Answer:
Equation in square form:
Extreme value:
Step-by-step explanation:
We are given
we can complete square
we can use formula
now, we can add and subtract 5^2
So, we get equation as
Extreme values:
we know that this parabola
and vertex of parabola always at extreme values
so, we can compare it with
where
vertex=(h,k)
now, we can compare and find h and k
we get
h=-5
k=-4
so, extreme value of this equation is
745/x=100/36
<span>(745/x)*x=(100/36)*x
</span><span>745=2.7777777777778*x
</span>(2.7777777777778) to get x
<span>745/2.7777777777778=x </span>
<span>268.2=x </span>
<span>x=268.2
</span>
answer <span>36% of 745=268.2</span>
Answer:
11a. 15x + 6
11b. x + 8 < 16 or x + 8 - 16
12. 3x + 15 + 5x = 8x + 15
13. 7x + 31
Step-by-step explanation:
Answer:
Y=-1/3x+2
Reason:
the line is negative so it Goes down one right 3 and the line is on the positive 2 on the y axis.
Based on the amount that Fatima wants to spend in total and the price of the sketch pads and pencils, the number of pencils she can buy is 12 to 18 pencils.
<h3 /><h3>What number of pencils can Fatima buy?</h3>
If Fatima bought 2 sketchpads, she would have spent:
= 3.25 x 2
= $6.50
If she spent at most $20, the amount to spend on pencils is:
= 20 - 6.50
= $13.50
Pencils are $0.75 so the number of pencils Fatima can buy are:
= 13.50 / 0.75
= 18 pencils
If she spent at most $15, the number of pencils to buy is:
= (15 - 6.50) / 0.75
= 12 pencils
Missing details from the question:
the sketchpad is $3.25 each and the pencils are $0.75 each
