Answer:
D. 4/7 = 24/28
Step-by-step explanation:
In any proportion, the value of the numerator and denominator does not change if is multiplied by the same value.
We know that 4*6 = 24, so the numerator holds true. However, 7*6 is 42. In the same vein, 7*4 is 28, so the denominator would hold true. However, 4*4 is 16. Thus, the proportion has not been multiplied by the same value.
In order to get 24/28 from 4/7, you would have to multiply by 6/4, which is not the same value.
Answer:
f(x) = (x + 4)² - 3
Step-by-step explanation:
The equation of a quadratic function in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² + 8x + 13
To obtain f(x) in vertex form use the method of completing the square
add/ subtract (half the coefficient of the x- term)² to x² + 8x
f(x) = x² + 2(4)x + 16 - 16 + 13
f(x) = (x + 4)² - 3 ← in vertex form
D=61d+30d=91d,
S=300+30d
S<D
300+30d<91d
300<61d
d>4.91 Since days are integers,
The skier would have to go at least 5 days to make the season pass less expensive than using the daily pass.
