Answer:
-4Step-by-step explanation:
Let the number be x:
2x = 5x + 122x - 5x = 12-3x = 12x = -4It is -4
What is the slope-intercept form of the linear equation x+4y=12?
Answer:
y = -x/4 + 3
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: x + 4y = 12
Step 2: Rewrite
Find slope-intercept form
Subtract x on both sides: 4y = 12 - xDivide 4 on both sides: y = 3 - x/4Rearrange: y = -x/4 + 3we know that
The equation of the line in the slope-intercept form is equal to
we have
Solve for y
Subtract both sides
Divide by both sides
therefore
the answer is
Y= 1/4x+3
14 Divide 2+3(4)-(61/2-3)

Which of the following does NOT show an identity property?
2 + 1 = 3
5 ÷ 1 = 5
3 − 0 = 3
4 × 1 = 4
Answer:
2+1 = 3
Step-by-step explanation:
The first one
2+1 = 3
the identity properties are :
n+0=n
n-0=n
n/1=n

Recycling Tim's family was collecting aluminum cans to recycle. They found out that they would get two.cents for every three cans they collected. If they collected 2,187 cans, how much money did they receive? EXPLAIN YOUR ANSWER PLEASE
Answer: They received $14.58
Step-by-step explanation:
Set up a proportional relationship
If 2 cents equal to 3 cans then we will represent how 2,187 will be worth by x.
[tex]\frac{0.02}{3} / \frac{x}{2187}[/tex] Cross multiply
3x = 43.74 Divide both sides by 3
x = 14.58
what is the value of x in the figure
Answer:
x is 35
Step-by-step explanation:
the two angles are opposite so they are equal
Answer:
x = 35°
Step-by-step explanation:
Vertical Angles
When two lines cross, two pairs of angles are formed. Those who are opposed by the vertex are called vertical angles and they are always congruent.
Congruent angles have the same measure.
Thus, the angle marked as x is opposed to 35° and they have the same measure, thus:
x = 35°

If f(x) = 5x^2– 3 and f(x + a) = 5x^2+ 30x + 42,
what is the value of a ?
Answer:
The zeros are x=0,3,-2
There is a multiplicity of 1 for all of them.
Step-by-step explanation:
The required value of a is 3 for the given function.
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function is given as follows:
f(x) = 5x²– 3
Substitute the value of x = x + a in the above function,
f(x + a) = 5(x + a)²– 3
f(x + a) = 5(x² + a² + 2ax) - 3
f(x + a) = 5x² + 5a² + 10ax - 3
f(x + a) = 5x² + 10ax + 5a² - 3 ....(i)
As per the question, we have f(x + a) = 5x²+ 30x + 42 ....(ii)
Equating the equations (i) and (ii),
So, 10a = 30
a = 30/10
a = 3
Therefore, the required value of a is 3.

The image of a point (1, 2) under a translation is (-5, -4) what is the translation vector
Answer:
u = vector (-6 , -6)
Step-by-step explanation:
u = vector(a , b)
Left (-) 6 units and down (-) 6 units
The translation vector for the image is (-6,-6).
What is a translation vector?A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. Vectors are given in the form ( x y ) where x is the movement horizontally and y is the movement vertically.
For the given situation,
The image of a point (1, 2) under a translation is (-5, -4) .
The translation vector can be found by calculating the movement horizontally and vertically as
⇒ [tex](-5-1,-4-2)[/tex]
⇒ [tex](-6,-6)[/tex]
Hence we can conclude that the translation vector for the image is (-6,-6).

Using a linear function, the statement that best describes when she advances to the next phase is: 75 + 3x > 90.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Considering that she already has 75 points, and earns 3 points for each correct answer, her score is modeled by the following function:
T = 75 + 3x.
She advances to the next phase if she scores over 90 points, hence the statement is:
T > 90
75 + 3x > 90.

The annual enrollment of a university for the last nine years is recorded in the table. What quadratic function best models this set of data?
Answer:
y = 0.14 x^2 - 1.43 x + 10.75
Step-by-step explanation
got it correct on the test
The quadratic function best models this set of data is y = 10.75x² - 1.43x + 0.14.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have data shown in the table:
It is required to find the quadratic function best models this set of data.
Let the quadratic function is:
y = ax² + bx + c
We can find the values of a, b, and c from the table, which are constants.
From the table:
a = 10.75
b = -1.43
c = 0.14
The quadratic function is:
y = 10.75x² - 1.43x + 0.14
Thus, the quadratic function best models this set of data is y = 10.75x² - 1.43x + 0.14.
