No, because it is not a straight line
Step-by-step explanation:
<u><em>f(a):</em></u>
So for this you simply plug in "a" as x, and this doesn't really do anything beside replace all values with x, so you just have the equation:
<u><em>2 f(a):</em></u>
So for this one, you want to represent f(a) using the equation it's equal to (5a + 4), and substitute it in for f(a). In doing so, you get the expression:
2*f(a) -> 2(5a + 4) -> 10a + 8
<u><em>f(2a):</em></u>
So this is very similar to the first question, although you will have to do some multiplication. So just plug in 2a as "x" to get the equation:
<u><em>f(a+2):</em></u>
Basically the same process, you plug in (a+2) as "x" and simplify:
<u><em>f(a) + f(2)</em></u>:
This is similar to the second question, and you simply want to replace the f(a) with the equation that represents it (5a + 4) and same thing for f(2) = 5(2) + 4
Answer:
D if car's length is 180 and not 108
Step-by-step explanation:
Truck is 75% longer than the car implies that the length of the truck is 175% (100+75 = 175) of the length of the car.
175/100 × 108
= 189 inches
None of the above
If we take the car's length to be 180 inches, then
175/100 × 180 = 315 inches
<span>the sequence is geometric, with the common ratio being 1/6 (48 * 1/6 = 8
The formula for a geometric sequence is cr^n where "c" is a constan</span>t <span> and "r" is the common ratio
=48(1/6)^n.
A geometric series converges only if the absolute value of the common ratio is < It diverges if the ratio is >or equal to 1.
the ratio is 1/6, so the sequence converges.
Now in this case, the limit seems to approach 0,
values can only keep getting smaller.
If the limit approaches 0, then the series will converge to a definite sum
S = c / (1 - are)
S = 48 / (1 - 1/6)
S = 57.6
series converges, has a limit of 0,
sum of 57.6.

-7(3x-1)
Let’s distribute that.
-7 x 3x = -21x
-7 x -1 = 7
Let’s rewrite, using the distributed numbers I just got.
91 = -21x + 7
Now, let’s solve for x.
91 -7 = -21x + 7 -7
(Remember, whatever you do on one side you do on the other)
84=-21x
84/-21=-21x/-21
-4=x
Solution : x=-4
