Answer:
A. coefficient
Step-by-step explanation:
A constant is the number that isn't with any variable, which in this case, the constant would be 15.
A variable is a unknown value, which in this case, the variable would be x.
The term are the numbers in the equation, which in this case, the terms would be 7x and 15.
The 7 in the expression 7x + 15 is the coefficient.
The correct option is A.
What is an expression?A term is composed of one mathematical expression. A single variable (a letter), a single integer (positive or negative), or a number of variables that have been multiplied but never added or subtracted are all examples of single variables. There is a number in front of certain words that are variables. A word or phrase is preceded by a coefficient.
In general, a coefficient is the numerical factor of a term that contains a variable. In this case, the term containing the variable x is 7x, and the coefficient of this term is 7. The term 15 is a constant term, which is a term that does not contain any variables.

whats 2+2x (7/7)= to
Answer:
2+2x(7/7)= 0 (you do what's in the parenthesis first)
2+ 2x (1) =0 (then you multiply, and anything times 1 is itself)
2 + 2x= 0 (subtract 2 from both sides to get the x-term alone)
2x= -2 (divide both sides by 2 to get x isolated)
x= -1 (is your answer)

Does 12cm, 7cm, 5cm, make a triangle
Answer:
No, it doesn't.
Step-by-step explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.) a + b > c
2.) a + c > b
3.) b + c > a.
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if all the two side lengths of a triangle is greater than the third side, then it makes a triangle.

Answer:
18 and 13
Step-by-step explanation:
The two numbers are 13 and 18 respectively.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the difference of two integers is 5. Twice the smaller integer is 8 more than the larger integer.
Assume the number to be [x] and [y]. We can write -
x - y = 5
2y = x + 8
2y = 5 + y + 8
y = 13
Then -
x = 13 + 5
x = 18

Considering the roots of function f(x), the correct statement is given by:
D. f has exactly two zeros of [0,4].
What are the roots of a function?The roots of a function are the values of x for which f(x) = 0.
In this problem, we have that:
f(2) = 0, hence x = 2 is a root.f(3) < 0 and f(4) > 0, meaning that between x = 3 and x = 4, there is a root of a function, as to go from negative to positive, it has to pass through f(x) = 0.For values of x less than 2 on the interval, the function is never negative nor zero, hence there are no roots in that interval and option D is correct.

Salim wants to purchase tickets from a vendor to watch a tennis match. The vendor charges a one-time service fee for processing the purchase of the tickets. The equation T = 15n +12 represents the total amount T, in dollars, Salim will pay for n tickets. What does 12 represent in the equation?
Given:
The equation [tex]T=15n+12[/tex] represents the total amount T, in dollars, Salim will pay for n tickets.
To find:
What does 12 represent in the equation?
Solution:
The vendor charges a one-time service fee for processing the purchase of the tickets.
We have, the equation
[tex]T=15n+12[/tex]
Here, 15 is the coefficient of n and 12 is constant.
If n is number of tickets then 15 must be the price of each ticket.
12 is free from variable and it is fixed. So, it represents one-time service fee for processing the purchase of the tickets.
Therefore, 12 represents that one-time service fee for processing the purchase of the tickets is $12.
Translate (3, – 4) down 3 units.
Then reflect the result over the y-axis.
Answer:
Step-by-step explanation:
Best advice: make a sketch (which I can't do here).
When you reflect in the x axis, only the y value changes...so (3, -4) reflects to (3,4).
Translating down (i.e. in the negative direction) again means the x value (the abscissa) doesn't change, only the y value (the ordinate)...so the final value of the point is (3,1).
Table of values are provided for functions f(x) = |x| and g(x) = -|x +2|+3.
Complete the table of values for the missing values of g(x).
Answer:
for answer to be 2
mod of x +2 should be equal to 1
so the answer will be x = -3 or -1
for x = 1 we will get gx 0
for g(x) = -2 mod x +2 should be equal to 5
so x is -7 or 3

A ball is thrown from a height of 40 meters with the initial downward velocity of 5 m/s. the ball's height h ( in meters) after t seconds is given by the following
h= 40 - 5t -5t^2
How long after the ball is thrown does it hit the ground?
round your answer(s) to the nearest hundredth.
The time which it will take for the ball to hit the ground after bring thrown from a height of 40 meters as described in the task content is; 2.37 seconds.
How long will it take for the ball thrown to hit the ground after being thrown from a height of 40meters?It follows from the task content that the equation given for the height, h in meters of the ball thrown is;
h = 40 - 5t - 5t²
Therefore, when the ball hits the ground, the height at this point is; 0.
0 = 40 - 5t - 5t²
Divide through by -5 so that we have;
t² + t - 40 = 0.
Hence, by solving using the quadratic formula; the values of t are;
t = 2.37 sec or -3.37 sec.
Ultimately, since the time taken can only have a positive value, it follows that the time taken by the ball to hit the from the 40 meters height is; t = 2.37.

On a coordinate plane, how are the locations of the points (-3 , -8) and (3 , -8) related? A. reflection across the x-axis B. reflection across both axes C. reflection across the y-axis D. locations unrelated
Given:
The locations of the two points are (-3 , -8) and (3 , -8).
To find:
The relation between two points.
Solution:
From the given points (-3 , -8) and (3 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.
If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,
[tex](x,y)\to (-x,y)[/tex]
For (3,-8),
[tex](3,-8)\to (-3,-8)[/tex]
So, it is reflection across the y-axis.
Therefore, the correct option is C.

A plane traveled 3355 miles with the wind in 5.5 hours and 2585 miles against the wind in the same amount of time. Find the speed of the plane in still air and the speed of the wind.
HELP QUICKKKKK
Answer:
Speed of the plane in still air is 540 mph,Speed of the wind is 70 mph
=======================
Let the speed of plane is x and speed of the wind is y.
The speed of the plane with the wind is x + y and speed of the plane against the wind is x - y.
Equation for speed:
speed = distance / timeSince the same amount of time spent in both cases, we can set equations:
x + y = 3355/5.5 ⇒ x + y = 610x - y = 2585/5.5 ⇒ x - y = 470Add up the two equations and solve for x:
x + y + x - y = 610 + 4702x = 1080x = 540Find y:
540 + y = 610y = 610 - 540y = 70Which of the following statements must be true if AGHI AJKL? Select all the apply.

Triangle ABC has coordinates A (0, 4), B (1, 3), and C (-2, 4). If triangle ABC is reflected over the x axis and then translated such that (x, y) → (x+3, y-1), what is the resulting image of point C?
The resulting image of point C is C''(x, y) = (1, - 5).
What are the coordinates of the image of a point by using a rigid transformation?
The triangle seen on the Cartesian plane is generated by three points on that plane. The image of the triangle is the result of reflecting the three vertices over the x axis and later translating them 3 units in the +x direction and a unit in the - y direction, two kinds of rigid transformations.
Now we proceed to show the entire procedure:
Reflection over the x-axis
C'(x, y) = C(x, y) + (0, - 2 · c)
C'(x, y) = (- 2, 4) + (0, - 8)
C'(x, y) = (- 2, - 4)
Translation
C''(x, y) = (- 2, - 4) + (3, - 1)
C''(x, y) = (1, - 5)
The resulting image of point C is C''(x, y) = (1, - 5).

why did you choose this strategy:
======================================================
Explanation:
Check out the diagram below
I drew a rectangle with dimensions 56 ft by 78 ft.
Then I broke up the 56 into 50+6, and I broke up the 78 into 70+8
The reason for this is because it's fairly easy to multiply the areas of each smaller rectangle at this point
In the upper left corner, we have an area of 50*70 = 3500. Note how this is basically 5*7 = 35, but we tack on the two zeros (from 50 and 70 combined)In the upper right corner, we have an area of 70*6 = 420In the lower left corner, we have an area of 50*8 = 400In the lower right corner, we have an area of 6*8 = 48Add up all the areas found: 3500+420+400+48 = 4368
As a way to check, using your calculator shows that 56*78 = 4368
