Okay so first let’s bring the variables to one side and the constants on the other side of the equal sign. (Remember that the sign changes for every coefficient/variable/constant.):

3b + b = -5 + 1 + 12

Add like terms:

4b = 8

Now you have to both sides by 4 considering that’s the biggest number 4 and 8 are divisible by:

b = 2

Your solution is b = 2

Suppose f(x)=2×+5 find the value of -2f(x+1)

loris [4]

F(x) = 2x + 5

-----------------------------------
Find f(x + 1) :
-----------------------------------
f(x +1) = 2(x + 1) + 5
f(x +1) = 2x + 2 + 5
f(x + 1) = 2x + 5

-----------------------------------
Find -2f(x+1):
-----------------------------------
-2(fx+1) = -2(2x + 5)
-2(fx+1) = -4x - 10

----------------------------------------------------------------------
Answer: -2(fx+1) = -4x - 10
----------------------------------------------------------------------

I need help please. I need the the discount and selling price. Thank you

salantis [7]

Answer:

<h2><u>15.12 is the discount</u></h2><h2><u>68.88 is the sell price</u></h2>

Step-by-step explanation:

When you are taking off percentages from numbers, you first want to make the percent a number. This step is super simple. Just divide the 18 by 100

This gets you 0.18

Now multiply

84 * 0.18 = 15.12

So 15.12 is the discount

Then take 84 and subtract 15.12

84 - 15.12 = 68.88

So 68.88 is the sell price

What step is wrong -12=4(f-6) step 1 12=4f step 2 4=f step 3

kirza4 [7]

Answer:

Step(iii)

The value of 'f' = 3

Step-by-step explanation:

Given - 12 = 4(f-6)

Multiply

- 12 = 4 f - 24

- 12 = 4 f - 24

Adding '12' on both sides, we get

- 12 + 12 = 4 f - 24 + 12

0 = 4 f - 12

4f - 12 =0

4 f = 12

<u><em>Step(iii):</em></u>-

Dividing '4' on both sides, we get

f = 3
