A home based sign company uses this function to model its monthly profit, where x is the price of each sign it sells. What is the company’s profit if each sign sells for $20
x = 10.1
step-by-step explanation:
all of the angles of a tirangle add up to 180º
180 - 65 = 115 (since we already know the value of one angle)
(2x + 7) + (8x + 7) = 115
(combins like terms) 10x + 14 = 115
(isolate the variable subtract 14 from both sides): 10x = 101
(find the variable divide both sides by 10): x = 101/10
x = 10.1
option a is correct.
step-by-step explanation:
scale factor: it is used to find proportional measurements.
proportions means having the same ratio.
scale factor is the ratio of the model measurement to the actual measurement in a simplest form.
or we can say that the ratio of any two corresponding lengths in two similar geometric figures
if the scale factor is more than 1, then it is an enlargement,
if the scale factor less than 1, then it is a reduction.
given the two geometric figure:
by definition of proportions, we have
