Answer:
(-2,4)
Step-by-step explanation:
This implies 
.
This means 
and 
.
Subtract 3 on both sides for first equation: 
.
Add 3 on both sides for the second equation: 
.
So the pre-image (x,y) is (-2,4) if the image is (1,1).
Let's check:
So the solution has been checked and verified.
Her profit was 126$ because she spent 24$ on her materials and then charged 5$ per 2 so you get 150$ then subtract the 24
(I think)
Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
The answer is 3.92 so the first one
