Answer:
An equation in slope-intercept form for this line is ![y=\frac{5}{2}x-19](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B2%7Dx-19)
Step-by-step explanation:
Slope intercept form : ![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We are given that A line passes through the point (4, −9) and has a slope of 5/2.
So, ![(x_1,y_1)=(4,-9)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%3D%284%2C-9%29)
![m = \frac{5}{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B5%7D%7B2%7D)
Substitute the value in the equation :
So,![y-(-9)=\frac{5}{2}(x-4)](https://tex.z-dn.net/?f=y-%28-9%29%3D%5Cfrac%7B5%7D%7B2%7D%28x-4%29)
![y+9=\frac{5}{2}x-10\\y=\frac{5}{2}x-10-9\\y=\frac{5}{2}x-19](https://tex.z-dn.net/?f=y%2B9%3D%5Cfrac%7B5%7D%7B2%7Dx-10%5C%5Cy%3D%5Cfrac%7B5%7D%7B2%7Dx-10-9%5C%5Cy%3D%5Cfrac%7B5%7D%7B2%7Dx-19)
So, an equation in slope-intercept form for this line is ![y=\frac{5}{2}x-19](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B2%7Dx-19)
Answer:
c
Step-by-step explanation:
an exponential function of the form
y = a![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
to find a and b use ordered pairs from the table
using (0, 0.5 ) , then
0.5 = a
[
= 1 ] , then
a = 0.5
so y = 0.5![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
using (1, 2 ) , then
2 = 0.5
= 0.5b ( divide both sides by 0.5 )
4 = b
then exponential function represented by the table is
y = 0.5 ![(4)^{x}](https://tex.z-dn.net/?f=%284%29%5E%7Bx%7D)
0-1/4-2/3-3/4-4/4
0-1/8/2/8-3/8-4/8-5/8-6/8-7/8
the answer is $7
Step-by-step explanation:
70 divided by 14 is 5.
cost would be $5 per person before discount of $2
$5 plus $2 equal $7
p= $7
