Given : Function f(x) = x⁵ + (x + 3)²

The Question is to find the image of the given function at x = -1

In order to find the image of a function for a given value, We need to substitute the value in the respective function

:\implies  f(-1) = (-1)⁵ + (-1 + 3)²

:\implies  f(-1) = -1 + (2)²

:\implies  f(-1) = -1 + 4

:\implies  f(-1) = 3

14. What is the solution of the system? Use elimination.<br> 9x + y = 30<br> 6x - y = 15
klemol [59]

Answer:

x=90/16,y=-150/16

Step-by-step explanation:

Simultaneous equation and we are to use elimination method

9x+y=30...(1)

6x-y=15..(2)

Add (1) and (2)

16x=15

Divide both sides by 16

x=15/16

Then substitute the value of x into (2)

6(15/16)-y=15

90/16-y=15

Substrate 15 from both sides

90/16-y-15=0

Add y to both sides

90/16-15=y

Lcm for only the left side which is 16

90-240/16=y

-150/16=y

Therefore x is 90/16 and y is -150/16

Suppose you average 82 on your first 7 test. What must you score on the eighth test to raise your average to 84?
natima [27]

so hmmm on average on the last 7 test, you get 82, so hmmm we could say that on each of the 7 tests you got 82, so you got 82, 7 times.

now, let's say in the 8th test, you get a grade of "g", now, if we were to get an average of all 8 tests, that means the average will simply be (82*7) + "g", and we know that's 84, so

\cfrac{(\stackrel{\textit{sum of all first seven tests}}{82+82+82+82+82+82+82})~~ + ~~g}{8}~~ = ~~84\implies \cfrac{(82\cdot 7)~~ + ~~g}{8}~~ = ~~84 \\\\\\ \cfrac{574+g}{8}=84\implies 574+g=672\implies g=672-574\implies g=98
