Answer:

Step-by-step explanation:

y=-1,869.5x+27,995

Step-by-step explanation:

Let

x-----> the time in years

y----> value of Zachary’s car in dollars

A(0,27,995), B(10,9,300)

step 1

Calculate the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute

m=\frac{9,300-27,995}{10-0}=-1,869.50

step 2

Find the equation of the line

The equation of the line into slope intercept form is equal to

y=mx+b

we have

m=-1,869.50

b=27,995  -----> the y-intercept is the point A

substitute

y=-1,869.5x+27,995

Answer:  " 4 − 3a " .

________

Step-by-step explanation:

" 4 − a − a − a " ;

        = 4 − 1a − 1a − 1a " ;

        =  ?  " ;

________

Combine the "like terms" :

________

         →   " − 1a − 1a − 1a " ;

               = (− 1a − 1a) − 1a ;

               = ( − 2a) − 1a ;

               =  − 3a ;

________

Now, bring down the "4" ;

  and rewrite the expression:

________

        →  " 4 − 3a " ;

which cannot be simplified further.

________

The answer is:  " 4 − 3a " .

Answer:

y=24x/13+317/13

Step-by-step explanation:

Answer:

So for the coorfinates of F, you have to see how far it is from y=1. The F is 2  points under the 1 so you have to count 2 above the 1. So the point would be (7,3). Same for the other ones. For example like D. It's 2 above 1 so its going to be 2 under which would result in (1, -1)

Hey there!

5x - 6y - 3a

= 5(-2) - 6(3) - 3(-4)

= -10 - 18 - 12

= -28 - (-12)

= -28 + 12

= -16

Therefore, your answer is: -16

Answer:

Step-by-step explanation:

This is a linear relationship.

Using the slope intercept form:

Given:

The equation is:

Answer:

m = 5 / 2

Step-by-step explanation:

Given

(4, 10)

Here,

x=4 and y=10

Given equation,

y=mx _ equation 1

putting the value of x and y in equation 1. we get,

y = mx

or, 10 = m4

or, 10 / 4 = m

or, 5 / 2 = m

therefore, m = 5 / 2

1) The equation 2y + 3x = 12 in the y = mx + b form is [tex]y = -\frac{2}{3} x + 4[/tex]

2) The linear equation y = -2x - 1 in the Ax + By = C form is 2x  +  y  =  -1

The point-slope form of the equation of a line is y = mx + b

where m represents the slope

b represents the y-intercept

The given equation is:

2x  +  3y  =  12    (Given)

Subtract 2x from both sides

2x  +  (-2x)  +  3y   =  12  +  (-2x)

3y   =  12 - 2x  (Equality property of addition)

3y   =  -2x  +  12 (Commutative property of addition)

Divide both sides by 3

[tex]\frac{3y}{3} = -\frac{2}{3} x + \frac{12}{3} \\\\y = -\frac{2}{3} x + 4[/tex](Equality property of division)

2) Write the linear y = -2x - 1 into Ax + By = C

y   =   -2x  -  1  (Given)

Add 2x to both sides

y  +  2x  =  -2x  + 2x - 1 (Equality property of addition)

y   +  2x   =  -1

2x   +   y   =   -1   (Commutative property of addition)

Answer:

Chelsea can make 3 [tex]\frac{1}{2}[/tex] batches of icing with 7/8 pounds of butter.

Step-by-step explanation:

7/8 ÷ 1/4  (reciprocate 1/4 to replace division sign with multiplication sign)

= 7/8 x 4/1

= 28/8

= 7/2

= 3 [tex]\frac{1}{2}[/tex]

This means that Chelsea can make 3 [tex]\frac{1}{2}[/tex] batches of icing with 7/8 pounds of butter.
