if p(x)=x*2-1 and q(x)=5(x-1),which expression is equivalent to (p-q)(x)?

umka2103 [35]

Answer:

$(p - q)(x) = (x -1) (x - 4)$

Step-by-step explanation:

Given

$p(x) = x^2 - 1$

$q(x) = 5(x - 1)$

Required

(p - q)(x)

This is represented as:

$(p - q)(x) = p(x) - q(x)$

$(p - q)(x) = x^2 - 1 - 5(x - 1)$

$(p - q)(x) = x^2 - 1 - 5x + 5$

Collec like terms

$(p - q)(x) = x^2 - 5x + 5 - 1$

$(p - q)(x) = x^2 - 5x + 4$

Expand

$(p - q)(x) = x^2 -4x - x + 4$

Factorize

$(p - q)(x) = x(x -4) - 1(x - 4)$

$(p - q)(x) = (x -1) (x - 4)$

Match each point with one of the following fractions 5/6, 7/12, 1/8, 5/16

BabaBlast [244]

What you need to do is make each fraction into a decimal and then put them in order from least to greatest.

7/12=0.583

1/8= 0.125

5/16= 0.3125

5/6= 0.83

The order for this is 0.3125, 0.125, 0.583, and 0.83. So the answer is last option

Why did the paper rip when the student tried to stretch out the horizontal axis of his graph

OlgaM077 [116]

The horizontal axis only goes so far on a paper so it can’t stretch without ripping.
