H/4=7/14
we cross multiply , so
14*h = 7*4
14h=28
divide by 14 on both sides
h=28/2=2
F(x) = 3x+1
put x = a+h
f(a+h) = 3(a+h) + 1
f(a+h) = 3a + 3h + 1
put x = a
f(a) = 3a + 1
f(a+h)-f(a) = 3a + 3h + 1 -(3a+1)
f(a+h)-f(a) = 3a +3h + 1 - 3a -1
f(a+h)-f(a) = 3h
Answer:
1) the factored form is y= ( x-5 ) ( x+4 )
2) the vertex is (4.5, -0.25)
3) the y intercept is when x equals 0 so it is at (0,20)
4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)
5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
Answer: The steak costs $ 7.67.
Step-by-step explanation:
Given: Cost per pound of Rib-eye steaks = $8.52
Ms. Markum bought a 0.9-pound steak.
To find : cost of 0.9 pound steak =
Then cost of 0.9 pound steak = 0.9 x (Cost per pound of Rib-eye steaks )
= $ (0.9 x 8.52)
= $7.668 ≈ $ 7.67
Hence, the steak costs $ 7.67.
