What is the value of b if -7+b= -8

Answer:

Step-by-step explanation:

Given:

To find h(g(f(x))) first find g(f(x)), substitute x with f(x):

Since g(x) = x², the value of g(2x + 5) is:

Now, the next step:

Answer: 4 months

Step-by-step explanation:

$75 + $152X = 683

That's the equation you need to set up, with X being the number of months.

To solve, first subtract 75 from both sides.

$152x = 608

Then, divide each side by 152

X = 4

The answer is 4 months.

Answer:

A) - 4x + 7

B) terms: 2x,-3,4x,-10x,10

Coefficients: 2,4,- 10

Constants: -3, and 10

Step-by-step explanation:

1/2(4x-6)+2(2x-5x+5)

2x-3+4x-10x+10 =

-4x+7

Answer:

m=7

Step-by-step explanation:

divide by both sides by 2 then you will remain with m is the equal to 7

Answer:

7

Step-by-step explanation:

2m = 14

=> m = 14/2

=> m=7

Answer:

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

7(-5)(x)+1 1+(x)(-5)7

= -35x+1 = 1+(-35x)

= 1-35x = 1-35x

So, the expressions are equivalent.

rational as it can be in form b/q

Answer:

x = 7

Step-by-step explanation:

8(5x + 2) = 296

40x + 16 = 296

40x = 280

x = 7

Answer:

x=7

Step-by-step explanation:

➼Okay, so first thing you need to do is to distribute the 8 to everything in the parentheses:

8(5x+ 2) = 296

8 times 5x

8 times 2

(8 x 5x) + (8 x 2) = 40x + 16

➼Now you solve for x

40x+16=296

➼to get rid of 40 you have to do the opposite and divide it by everything

40x+16=296

40/40=0

16/40=0.4

296/40=7.4

➼all adds up to x + .4 = 7.4 but to get the x alone you need to get rid of the .4, we'll do this by doing the opposite and subtract it from everything

.4-.4=0

7.4-.4=7

➼so in conclusion

x=7

Answer:

the awnser of this question is 3,5,8

Answer:

Step-by-step explanation:

(f-g)(x) = f(x)- g(x)

= (3x + 7) - (3x)

= 7

Therefore (f-g)(x) = 7

Answer:

(f - g)(x) = 7

Step-by-step explanation:

Here, we should subtract the two functions:

f(x) = 3x + 7  and g(x) = 3x

(f - g)(x) = 3x + 7 - 3x

            = 3x - 3x + 7

           = 7

Hence, (f - g)(x) = 7

Answer:

150

Step-by-step explanation:

The overall answer should equal 360. 90+90+30=210. That leaves us with x. Try subtracting 360-210=x. :) Hope this helps!

Answer:

m = 1/3

Step-by-step explanation:

-3.3m = -1.1

(-3.3/-1.1)m = (-1.1/-1.1)

3m=1

3m/3 = 1/3

m = 1/3

Answer:

Step-by-step explanation:

1/3

Answer:

(13,-6)

Step-by-step explanation:

The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.

First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.

Then do the same thing with the y coordinate. And you get -6.

Your endpoint is (13,-6)

Answer:

x= (1,8)

Step-by-step explanation:

Answer:

Step-by-step explanation:

-3≤ 6x - 9                 Add 9 to both sides

-3 + 9 ≤ 6x               Combine left

6 ≤ 6x                       Divide by 6

6/6 ≤ 6x/6

1 ≤ x

6x - 9 < 39               Add 9 to both sides

6x < 39 + 9              Combine

6x < 48                     Divide by 6

6x/6 < 48/6

x < 8

So the inequality is

1 ≤ x < 8

I think that is what you want. You have to express it as a combined inequality.

Answer:

u > - 7

Step-by-step explanation:

7u - 32 < - 3(6-3u)

7u - 32 < - 18 + 9u

18-32 < - 7u + 9u

-14 < 2u

2u > - 14

u > - 7

Answer:

The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.

Step-by-step explanation:

To check whether the sequence proves that shape I is similar to shape IV, check whether the given sequence of transformations maps shape I onto shape IV.

1. Dilate shape I by a scale factor of 2.

2. Then, reflect the dilated shape across the x-axis.

3. Finally, translate the reflected shape 1 unit left.

Answer:

add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate

Answer:

147

Step-by-step explanation:

If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Answer:

Step-by-step explanation:

a) Number = x

Multiply it by 3 = 3*x = 3x

Now add 4 to it: 3x + 4

Equation:  

3x +4 = 22

b)

3x + 4 = 22

Subtract 4 from both sides

3x + 4 -4 = 22 - 4

        3x = 18

Divide both sides by 3

3x/3 = 18/3

x = 6

Answer:

Below in bold.

Step-by-step explanation:

The equation is

3x + 4 = 22

3x = 22 - 4 = 18

x = 18/3

x = 6.
