Answer:
no answer choices shown but solution
would be [-2.8, -∞] and [2.83, ∞]
Step-by-step explanation:
Multiply first and last coefficients:
2*(-9) = -18
Find 2 factors which multiply to -18 and add up to 17:
18 and -1
Rewrite quadratic with 17y split up as' 18y - y', Then factor by grouping:
About 2 feet and 2 inches
y - 0 = 5(x-4)
y = 5x-20
5x - y = 20 Standard Form
Answer:
114.
Step-by-step explanation:
- remove parenthesis
- multiply the numbers 6 x 3 + 18
18 + 4 + 2 x 3 x 15 + 2
multiply the numbers 2 x 3 x 15 + 90
18 + 4 + 2 + 90 + 2
add the numbers : 18 + 4 + 2 + 90 + 2
= 114!
