you can multiply 1.5 by 1.25 to get your answer
1.5 * 1.25 is 1.875
so the percent increase is 87.5 percent
a) 4k^2 + k – 5) + (7k^2 + 2k + 6)
11k^2 +3k +1
Choice A
Problem 1: Plug in the given value into the function and evaluate.
Problem 2: Solve the equation for y.
add 7x to both sides to move it to the right side of the equation.
Divide both sides of the equation by 2 to get a single y variable on the left hand side.
Simplify the terms to get the the equation into slope-intercept form.
The slope of the line is
I'm a unsure what Problem 3 is asking for sorry I hope the rest is helpful.
