Step-by-step explanation:
This can be modeled by the equation f(x)=7+5x
Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22
If x=50 then f(50)=7+5(50)
f(50)=$257
Answer: B!
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
Write the expression
-2x²y
substitute the real values with x=-3 and y= -1
-2(-3²)×(-1)
-2(9)×(-1)
-18×-1

Answer:
12,686
Step-by-step explanation:
add both numbers up then multiply by 2
First, you have to give each a variable. In this case, the smaller number will be x and the larger number will be y.
Next, you need to make the equations. Your equations are:
y+3x=14
x+2=y
What you're solving for is y because the questions asks what the larger number is.
Then, substitute. It will be this after substituted:
x+2+3x=14
Combine like terms.
4x+2=14
Subtract by 2 on both sides.
4x=12
Divide by 4 on both sides.
x=3
^This what your smaller number is but you can easily find what y (the larger number) is. Substitute x into the other equation, which is basically adding 2 to 3.
y=5
