We have the inequality:
We can solve it by dividing each side by 8:
Answer: x<=7 (Option A).
Answer:
y = -1
Step-by-step explanation:
Details have been given in the question, we need to break them apart and create our equations accordingly.
"the sum of two times x and 3 times y is 5"
2x + 3y = 5
"the sum of two times x and 3 times y is 5"
x - y = 5
So, our two equations are:
2x + 3y = 5
x - y = 5
Solve using substitution method, by moving y to the other side.
x = y + 5
2(y + 5) + 3y = 5
2y + 10 + 3y = 5
Combine like terms
5y + 10 = 5
Subtract 10 from both sides
5y = -5
y = -1
Answer:
720
Step-by-step explanation:
600*.2=120
120+600
720
Yes, f(x) = 16 - 7x is a linear function because there are no exponents and the rate of change (which is the slope) only adds or subtracts a certain number each time.
