Answer:
3x + 5 = 30
Step-by-step explanation:
Tate has 2x + 5 pennies and since Tate and Mia have 30 pennies all together you would add an x to the equation of how many pennies Tate has and set it equal to 30 making the equation 3x + 5 = 30
y = k/x, where k is the variation constant.
We need to find k.
5 = k/15...This equation leads to the correct value of k (our variation constant).
5(15) = (k/15)(15)
75 = k
Done!
Answer:
3x-7y
Step-by-step explanation:
9x^2 - 49y^2
find the square root of a values
=3x-7y
First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665
