Answer:

y= -3/2x - 5

Step-by-step explanation:

Substitute (-6,4) into equation:

y = -3/2x + c

4 = -3/2 x -6 + c

4 = 9 + c

-9

-5 = c

A bakery sells 3642 pastries in 2010. The bakery sells 8422 pastries in 2015. Write a linear model that represents the number y

Simora [160]

Answer:

y = 936x + 3742

Step-by-step explanation:

If it is a linear model, then we should have a slope and y-intercept with the equation representing the model as;

y = mx + c

where m is the slope and c is the y-intercept

Thus, we have for the slope;

(8422-3742)/(2015-21010) = 4680/5 = 936

So the equation will be;

y = 936x + c

To get c , we can use the years after 2010 which is 2015 in this case

8422 = 936(5) + c

c = 8422- 4680

c = 3742

So the linear model is;

y = 936x + 3742

The diameter of a circle has endpoints whose coordinates are R(-2, 2) and S(4, 2). The radius of the circle has length _____.

expeople1 [14]

A - 3

Using the coordinates of the diameter, it is possible to figure out the radius.

Using the y axis, you can determine that 4 and -2 total to be six apart, leaving the diameter to be six. Knowing that the radius is half of the diameter, you can easily split the diameter in half to get the radius of 3.

Hope this helps!

PLEASE HELP!!!!!!!!

Taya2010 [7]

Answer:

Step-by-step explanation:

A quadratic equation is

$ax^{2} +b+c$

The axis of symmetry is 1. This means that some value of

-b/2a =1.

f(0) represent one of the horinzontal roots. Since f(0) equal 0, the constant is 0.

Notice how x=1 is the line of symmetry. This means when x=4 and x=-2, the quadratic is equal. so consider this equation.

$a(4)^{2} +b(4)= a(-2)^{2} +b(-2)$ =-24

16a+4b= -24

4a-2b=-24

Solve for a by elimination.

2(4a-2b=-24)= 8a-4b=-48

Add both equations.

(16a+4b=-24)+(8a-4b=-48)= 24a=-92

Solve for a.

24a=-92

a=-3

Subsitute to in for b.

16(-3)+4b=-24

-48+4b=-24

4b=24

b=6

This means a=-3

b=6

So b-a is

6+3=9
