Answer:
Matt should have factored out the leading coefficient 2 on the second step before completing the square
Step-by-step explanation:
To complete the square, you must first factor the leading coefficient from the first two terms.
y = 2x² − 10x − 4
y = 2 (x² − 5x) − 4
y = 2 (x² − 5x + 25/4 − 25/4) − 4
y = 2 (x² − 5x + 25/4) − 25/2 − 4
y = 2 (x − 5/2)² − 33/4
9 the smallest angle is always opposite the smallest side
Answer: choice d, angle B
They couldn't match the choice letters with the angles? Geez.
10. That's an isoscles triangle
d + d + 116 = 180
2d = 64
d=32
choice a
11. 62+45+k=180
k=180-107 = 73
choice b
The order from least to greatest would be 1/5, 1/3, then 4/6.
To solve, multiply the fractions so that they all have the same denominator. I multiplied the 1/3 by 10, 1/5 by 6, and 4/6 by 5. After they all have a common denominator, you can easily order them from the numerator.
10(1/3) = 10 / 30
6(1/5) = 6 / 30
5(4/6) = 20 / 30
6/30, 10/30, 20/30
Hope this helps! :)
