Answer:
1. x=1
2. x=7
Step-by-step explanation:
1. -8(1+4x)+7x=-25-8x
-8-32x+7x=-25-8x
8x-32x+7x=-25+8
-17x=-25+8
-17x=-17

2. -5+6(x-7)=-40+5x
-5+6x-42=-40+5x
-47+6x=-40+5x
x=47-40
x=7
Answer:
-1/3
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 9-10)/(10-7)
= -1/3
Answer:
The answer is 4.2 kilograms of dog food
Step-by-step explanation:
it says that ray feeds his dog 0.12 kilogram of food each day
he needs for 1 month
1 month = 31 days or 30 days
since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month
i.e; 0.12*31 or 0.12*30
0.12*31=3.72 and 0.12*30=3.6
since we don't have an option we'll have to choose something bigger than this
therefore, the answer is 4.2
