Answer:
Step-by-step explanation:
<u>Solving by completing square</u>
- -14 + x^2 = 5x
- x^2 - 5x - 14 = 0
- x^2 -2*2.5x + 6.25 - 20.25 = 0
- (x -2.5)^2 = 20.25
- (x - 2.5)^2 = 4.5^2
- x - 2.5 = 4.5 ⇒ x = 7
- x - 2.5 = -4.5 ⇒ x = -2
Answer:
c)
Step-by-step explanation:
A function is a relation that maps each input to exactly one output. It may be linear or non-linear, and may have positive, negative, or zero slope.
<span>They use 9 blocks each, a total of 18 blocks.
Bill: 4b + 2
Ron: 8b - 5
To look for the value of b; I assume that both used the same number of blocks.
4b + 2 = 8b - 5
4b - 8b = -5 -2
-4b = -7
-4b/-4 = -7/-4
b = 1.75</span>
Bill: 4b + 2 where b = 1.75 ; then, 4(1.75) + 2 = 7 + 2 = 9
<span>Ron: 8b - 5 where b = 1.75; then, 8(1.75) -5 = 14 - 5 = 9</span>
Because the triangles are similar, their corresponding sides will have the same ratio. Side corresponding to PQ is AC and side corresponding to RC is PR. Thus:
RC/PR = AC/PQ
5.1 / 3.4 = 4.2 / PQ
PQ = 2.8 inches
