Step-by-step explanation: p(x) =18-5(-2) = 28
value of p(-2) is 28.
Answer:
3.39 + 0.59x
Step-by-step explanation:
Cost of a dish of ice cream = $3.39
Cost of toppings = $0.59 each
x = number of toppings
which expression can be used to determine the total charge in dollars, for a dish of ice cream with x toppings
Total charge for a dish of ice cream with x toppings = 3.39 + 0.59x
The expression is 3.39 + 0.59x
Answer:
1.6%
Step-by-step explanation:
The real GDP is given by the nominal GDP divided by the GDP deflator, the real GDP for year 1 and year 2, respectively, were:
The percentage change in GDP is:
Between year 1 and year 2, real GDP rose by 1.6%.
The correct answer is 75.7°.
The figure is described as a right triangle with a hypotenuse of 85, a base of x, and an angle at the top of 63°.
We have the side opposite the angle, x, and the hypotenuse. Opposite/hypotenuse is the ratio for the sine function:
sin 63° = x/85
Multiply both sides by 85:
85(sin 63°) = x
75.7 = x
Answer:
46
Step-by-step explanation:
PR = PQ + QR
4x - 10 =<u> x + 2x</u> + 4 {Combine like terms}
4x - 10 = 3x + 4 {Add 10 to both sides}
4x = 3x + 4 + 10
4x = 3x + 14 {Subtract 3x from both sides}
4x - 3x = 14
x = 14
PR = 4x - 10 {Plugin x = 14}
= 4*14 - 10
= 56 - 10
= 46
