Step-by-step explanation:

$4(3 + c) + c = c + 4 \\ 12 + 4c + c = c + 4 \\ 12 + 5c = c + 4 \\ 12 + 4c = 4 \\ 4c = 4 - 12 \\ 4c = - 8 \\ c = - 2$

If p(x) = X squared -1 and q(x) = 5(x-1), which expression is equivalent to (p-q)(x)

hram777 [196]

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

p(x)-q(x)= $x^2-1$ -5(x-1)
p(x)-q(x)= $x^2-1$ -5x+5
p(x)-q(x)= $x^2-5x+4$
(p-q)(x)= $x^2-5x+4$
or factored
(p-q)(x)=(x-4)(x-1)

Larisa earns $7 per hour.she worked 40 hours at the regular rate, 3 hours at time and half, and 6 hours at double time.

VARVARA [1.3K]

Answer:

$6.07/hr. if I understand the question properly. See below.

Step-by-step explanation:

I don't see the question, but will assume we want to find Larisa's base pay. The $7/hr given is the average for the work sequence noted in the problem. If this is incorrect, ignore the answer.

==================================

Let x be Larisa's base salary. We are told, I think, that in one stretch of time Larisa earned an average of $7/hour. That was composed of:

Hours Rate($/hr)

40 x

3 1.5x

6 2x

Her total income over this period would be:

40x +3(1.5x) + 6(2x) [The hours worked times the pay rate for each period]

Her average income per hour would be:

(40x +3(1.5x) + 6(2x))/49

which we are told is $7/hr.

(40x +3(1.5x) + 6(2x))/49 = 7
