It's not a linear equation, but its grapg is a straight line.
It is a linear equation, and its graph is a straight line.
It's not a linear equation and its graph is not a straight line.
it's a linear equation, but the graph is not a straight line
Answer:
The given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Step-by-step explanation:
Given the equation
y = -2x +30
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
The graph of y=mx+b is a straight line as it is the line equation.Writing the equation in the slope-intercept form
y = -2x +30
y = mx + b
Thus,
m = -2
b = 30
Thus, the given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Lin bought x grams of sugar. Jada bought 3⁄4 more than that. what is the equation that will represents the relationship between the amount of sugar that Lin bought, x, and the amount of sugar that Jada bought, y.
Answer:
y = 7/4xStep-by-step explanation:
Lin bought x grams of sugar.
Jada bought 3⁄4 more than Lin bought.
The equation:
y = x + 3/4x ⇒ y = 7/4xBut his teacher that he needed to measure the height of a building in which his classroom is located he backs away from the building and places a mirror on the ground between him and the wall when he can see the top of the building in the mirror Peter is 2‘9“ away from the mirror and the mirror is 11 feet away from the wall of the building Peter knew his eye level was exactly 5‘6“ off the ground so he was able to calculate the height of the building how tall is the building in feet

Jeremy was 45 inches tall when he started kindergarten. He grew an average of 2.5
inches every year. Jeremy is now 62.5 inches tall.
Which equation can be used to find how many years ago Jeremy started kindergarten,
and how many years ago was it?
Answer:
subtraction
Step-by-step explanation:
its subtraction because if you do 62.5-2.5 it = 60 and then 60-2.5=57.5 57.5-2.5=55 55-2.5=52.5 52.5-2.5=50 50-2.5= 47.5 47.5-2.5 = 45 s so it was 7 or 8 years ago idk count them see how many times i did it

If the binomial (x−7) is a factor of the polynomial function f(x), which statement must be true?
If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0
How to determine the true statement?The given parameters are
The binomial (x−7) is a factor of the polynomial function f(x)
The above means that
When the function f(x) is divided by x - 7, it has no remainder
So, we have
x - 7
Set to 0
x - 7 = 0
Add 7 to both sides
x = 7
Substitute x = 7 in f(x) = 0
f(7) = 0
Hence, if the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

The surface area of the triangular prism pictured below is 204 square centimeters. What is the height of the prism?
Answer:
height x=21.5cm
Step-by-step explanation:
Surface area = 2+ area of triangles + area of the 3 rectangles
SA = 204
204 = 4*3 + x*5 + 5*4 + x*3
204 = 12 +20 +8x
204 -12-20 = 8x
172/8 = x
21.5 = x
Solve for x plz. Ens
Answer:
9
Step-by-step explanation:
triangles always = 180 degrees
we know there is a 90 degree angle so 180-90=90
we know the other angle is 20 degrees so you do 90-20 which equals 70
now we know that the angle with x equals 70
so then you do 70-16 which equals 54
now just divide 54 by 6 and you get 9
so x=9
hope this helped ;)
Use the discriminant to describe the number of solutions of the equation 2x^2+5x−12=0
Multiple choice question.
A)
The discriminant is 121, and the equation has two real, rational roots.
B)
The discriminant is 121, and the equation has one real, rational root.
C)
The discriminant is –71, and the equation has two real, irrational roots.
D)
The discriminant is –71, and the equation has two complex roots.
Answer:
a = 2
b = 5
c = -12
The discriminant is sqr root (b^2 - 4*a*c)
= sqr root (25 -4 * 2 * -12)
= sqr root (25 + 96)
= sqr root (121)
Answer is A)

What is the domain of the function f(x) = + 5?
f(x) ≥ –9
f(x) ≥ –5
f(x) ≥ 5
f(x) ≥ 9
Answer:
The domain of the function is:
[tex]\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)\:=\sqrt{x+5}[/tex]
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
From the function, it is clear that for the values x<-5, the function becomes undefined.
For example, for x=-6
√x+5 = √-6+5 = √-1 which is undefined
and for x=-5
√x+5 = √5+5 = √0 which is defined
Thus, the domain of the function is:
[tex]\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}[/tex]

The common difference is positive because the arithmetic sequence is increasing.
Answer:
B. arithmetic sequence; 9
Step-by-step explanation:
An arithmetic sequence is a sequence where there is a common difference between each term. A common difference is a number that is added to the previous term to get the current term. For a sequence to be considered arithmetic this common difference must remain constant. This sequence is arithmetic because each time 9 is added to the previous term to get the next one. So the common difference is 9 and B is correct.
