Answer:
1. -8,
2. 58
3. 0
4.
5. -14/8 or -1.75
Explanation:
1. You just plug in 8 for x into the g(x) equation
So, -(8)^2+7(8)= -8
2. You do the same thing you did for number one.
Plug in 13 for the h(x) equation
|2-4(13)|= 50
Then plug in -1 for the f(x) equation
-(-1)^2+7(-1)= -8
You then do as it says- subtract h(x) from f(x)
Which is 50-(-8) and you get 58.
(That subtraction sign turns into addition/ 2 negatives make a positive)
3. Same thing again.
Plug in what they gave you (3y-1) for X
8(3y-1)-9
You get 24y-17
You then subtract off the -17 and get 24y=17
Divide the 24 off and get y=17/24
Plug the Y back into the equation
8(3(17/24)-1)-9 and you get 0
*Im not a hundred percent sure I did this one right*
4. This is the same as number 3. Didn’t have time to solve this, but it’s the same steps as number 3 :)
5. This time they didn’t give you x so you set it up differently
Now you set the f(x) equation equal to -23
8x-9=-23
Add off the to the 23 to isolate the variable
8x= -14
Divide off the 8
X= -14/8 or -1.75
Answer:
Step-by-step explanation:
8 multiplied by .75 = 6 which is 25 percent off.
Answer:
Hi there, we are going to set up a proportion. 640 miles/25 hours ÷ 25/25. That would equal 25.6 miles/1 hours. Therefore, the answer is 25.6 miles per hour.
Step-by-step explanation:
PLZZ MARK BRAINLIEST THAT WILL MEAN SOOO MUCH TO ME
271, since if the last 4 numbers didn't change, you can only change the first 3, so that would be 270 different numbers, not forgetting just 2014 so it makes it 271
Answer:
The answer is 48a-6b-14
Step-by-step explantion:
simplify by combining liketerms:
-6- 2b•3 -6a+ 10a• 3-16÷ 2- 4 • -6a
-6-6b-6a+30a -8+24a
48a-6b-14
Good luck!
