Answer: f(a-2) = 2a² - 14a + 28
Step-by-step explanation:
f(x) = 2x² - 6x + 8
you can take a-2 and substitute it for each x, which would look like this:
f(a-2) = 2(a-2)² - 6(a-2) + 8
then distribute those in ( )
f(a-2) = 2a² - 8a + 8 - 6a + 12 + 8
combine like terms
f(a-2) = 2a² - 14a + 28
Answer:
3.162
Step-by-step explanation:
√10 = 3.162
2 3/4a=9 1/4
2.75a= 9.25
cross off 2.75 and a will remain
divide 9.26 and 2.75
so a=3.36363636
a=<span>3.36363636
but you can round it to a=3.4ish i guess</span>
Answer:
a) F(d)=350+0.06d
b)$390.2
Step-by-step explanation:
350+0.06(670)=390.2
<u>Given</u>:
On a coordinate grid, point M is at (-8,2) and point S is at (10,2).
We need to determine the distance between the points M and S.
<u>Distance between the point M and S:</u>
The distance between the points M and S can be determined using the formula,
Substituting the points (-8,2) and (10,2) in the above formula, we get;
Simplifying, we have;
Taking square root, we get;
Thus, the distance between the points M and S is 18 units.
