Answer:
215; 8; 367
Step-by-step explanation:
231=7x+c
319=18x+c
c=The amount from bake sale (since it doesn't changes throughout the car wash)
x=$ earned per car
319=18x+c
-(231=7x+c)
Use elimination and subtract the values to get rid of a variable.
(319-231, 18x-7x, c-c)
88=11x
x=88/11
x=8
∴ The soccer team earns $8 per car.
231=7*8+c
231=56+c
c=231-56
c=175
∴ The soccer team made $175 from the bake sale.
The ans. is per blank from top ro bottom
1. c+5x=175+5*8
175+40 = 215
2. 255=c+?x
255=175+?*8
255-175=?*8
80=?*8
?=80/8
The soccer team washed 8 cars n earned $255
3. c+24x=175+24*8
175+192= 367
The soccer team earned $367 after 24 cars.
y=-5x-44
Step-by-step explanation:
5x+y=13 passes through (15,31)
rearrange the equation to y=mx+c
5x+y=13
y=-5x+13
substitute the points (15,31)
y=5x+c
31=5(15)+c
31=75+c
-44=c
y=-5x-44
Can be written as 5x+y=-44

Solution:
we have been asked to find
The equation of the line that has a slope of 1/4 and a Y intercept of -3.
The standard equation of straight line in the slope-intercept form is given by the formula
where m is the slope of the straight line and b is the y-intercept.
Substitute the given values we get
Hence the equation of the line that has a slope of 1/4 and a Y intercept of -3 is
