Answer:
19
Step-by-step explanation:
f(x) = 3x^2-3x + 1
Let x = -2
f(-2) = 3( -2)^2-3*-2 + 1
= 3 * 4+6+1
= 12 +6+1
= 19
Part A
49-14 = 35
<span>35/7 = 5 </span>
Part B
5 miles each day
Part C
<span>49+35 = 84 </span>
<span>84+40 = 124, which is a good estimate and it is reasonable</span>
Answer:
Yes she can.
Step-by-step explanation:
Val can make 6 slides in an hour.
1/6 * 60 minutes = 10 minutes. per slide
10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.
=====================
In one hour, she can produce 6 slides.
In two hours, she can produce 12 slides (2 * 6 = 12)
Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.
It would be C since it would be f(x) = 7x
