Answer:6(a)+4(b)+9(c)
Step-by-step explanation:
Im pretty sure there was an equation that you did not put.
But the equal used to solve would be 6(a)+4(b)+9(c)
a= money earned pulling weeds
b=money earned raking leaves
c=money earned cutting grass.
Answer:
x intercept is -3
Step-by-step explanation:
We need to find the equation for the line
First we find the slope
m = (y2-y1)/(x2-x1)
= (2- -4)/(6- -3)
= (2+4)/(6+3)
=6/9
= 2/3
The we can write the equation
y= mx+b
y = 2/3x +b
We can substitute in (6,2)
2 = 2/3(6) +b
2 =4+b
Subtract 4 from each side
2-4 =b
b =-2
y = 2/3 x-2
We want to find the x intercept, so set y =0 and solve for x
0 = 2/3x -2
Add 2 to each side
0-2 = 2/3x
Multiply each side by 3/2 to isolate x
-2 *3/2 = 2/3x * 3/2
-3 =x
The x intercept is -3
Use law of sines and cross multiply and simplify
