Step-by-step explanation:
See figure for intermediate steps.
From question,
lacy learned 34 recipes in 17 weeks,
so in 1 week she learns = 34/17 =2 recipes,
hence she learns 40 recipes in
= 40*2
=80 recipes.
Answer:
6 and 36
Step-by-step explanation:
I just took the test.
Answer:
y = 6x² -13x -5
Step-by-step explanation:
(1,-12) (2,-7) (5,80)
y = ax² + bx + c
-12 = a*1² + b*1 + c = a+b+c (1)
-7 = 4a + 2b + c (2)
80 = 25a + 5b + c (3)
(2)-(1): 3a + b = 5 (4)
(3)-(2): 21a + 3b = 87 (5)
(4)*3: 9a + 3b = 15 (6)
(5)-(6): 12a = 72 a = 6
(4) b = -13
(2) c = -5
Heather runs 7 miles in 80 minutes.
At the same rate, how many miles would she run in 64 minutes?
Let x represent miles would she run in 64 minutes?
Question Sets Up the Proportion
7/80= x/63 |Cross Multiplying to solve for x
x = 7*64/80
x = 5.6mi
Hope this helps!
