F(x)=x^2 +8x
f(d-3) basically what we get from this is that the x value is d-3
to find f(d-3) simply plug in d-3 for every x
f(d-3)=(d-3)^2 + 8(d-3)
that would be one form of the answer, but we can also continue multiplying it out
f(d-3)= d^2-6d+9+8d-24
add like terms
f(d-3)=d^2+2d-15

have a nice day and i hope this helps :)

Given that lines b and c are parallel, and the m<1=4x-30 and m<5=2x+50. Find the measure of angle 1 and measure of angle 7

AfilCa [17]

4x-30=2x+50
+30 +30

4x=2x+80
-2x -2x

2x=80
/2 /2

X=40

4(40)-30=130°

2(40)+50=130°

180-130=50°

Angle 7=50°

The explicit rule for a sequence is

pishuonlain [190]

For an explicit formula in its simplified form, we must evaluate the first two terms.

For $a_n=48-11n$ , $a_1=48-11=37$ , and $a_2=48-22=26$ . We see that the common difference is $37-26=-11$ , and $a_1=37$ , so we write,
$a_1=37, \ \ \ a_n=a(n-1)-11$ .

The correct answer is B.
