Answer:
b. x = 11/8, x = 59/72.
Step-by-step explanation:
4|8x - 6| = 5|-8x + 7|
square both sides:
16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)
1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0
576x^2 - 1264x + 649 = 0
x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)
x = 11/8, x = 59/72.
Answer:
103 to 107 is (2). 108 to 112 is (4). 113 to 117 is (2)
Step-by-step explanation:
You are 11 and 14
You can find this by guessing and checking, add any numbers that are 3 apart from each other.
14-11=3
14+11=25
I think the second one. as a pilgrimage, with some “warring on the side”.
Answer:
the quickest way would be to "complete the square"
on x^2 + 5x - 7
you will end up with (x+2.5)² = 13.25
or
y = (x+2.5)²-13.25
the vertex
VERTEX: (-2.5,-13.25)
Solution/X-Intercepts: -6.14 AND 1.14
