Answer:
1.) 5(4)-3(5)+8
20-15+8
5+8
13
The other ones make no sense. Can you take a picture of the problems
Slope intercept looks like this:
y = ax + c
So:
-5y = 9x + 35
We need to isolate y, so divide both sides by -5:
y = -
x - 7
2x-1=3/4x+9
2x-3/4x=9+1
1.25x=10
X= 8
Answer:
Sum is 1836.
Step-by-step explanation:
