The answer is 10 i believe
Ok so since the ratio is 7:5 that means you have an 8'' sandwich with 12 (7+5) separate units. imagine drawing the sandwich and dividing it into 12 sections.
so 8/12= .6666666 (thats the length of 1 unit)
now take .6666666 x 7 units = 4.6666666 inches '' (thats the bigger half)now take .6666666 x 5 units = 3.333333333 inches (thats the shorter half)
you'll notice that 4.66666666'' + 3.3333333" = 8''
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = (x + 7)² - 9 ← is in vertex form
with h = - 7 and k = - 9
vertex = (- 7, - 9 )
