Simplify the expression 9−8b+6b 9−8b+6b . 9−8b+6b=?? haha last one XD

1 answer:

5 0

You should get it now from my previous answer.

But to apply it.

9 - 8b + 6b
9 + (-8b + 6b) <- Collect like bases (b)
9 + (-2b)
9 - 2b

Therefore it simplified is 9 - 2b

2. 2(x+1.25) = 3.5

dangina [55]

Answer:

x = 0.5

Step-by-step explanation:

Given

2(x + 1.25) = 3.5 ← divide both sides by 2

x + 1.25 = 1.75 ( subtract 1.25 from both sides )

x = 0.5

Find the slope of the line that passes through the given points (-1.6) and (8.4) Select the correct choice below and, if necessa

fiasKO [112]

Answer:

The slope is $m=-\frac{2}{9}$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(-1,6)\ B(8,4)$

Substitute the values

$m=\frac{4-6}{8+1}$

$m=\frac{-2}{9}$

$m=-\frac{2}{9}$

A fitness club has two options, one for members and one for nonmembers. Members pay a one-time registration fee of $12 plus $8 p

Liula [17]

Answer:

See below.

Step-by-step explanation:

Let's look at the cost for members (C1) first. Let x be the number of visits.

C1(x) = 12 + 8x

For non-members (C2), we can do the same.

C2(x) = 10x

You can graph these two equations.

x C1 C2

0 12 0

1 20 10

2 28 20

3 36 30

4 44 40

5 52 50

6 60 60

7 68 70

Let's make the two equations equal, to find out where the benefit is the same.

12 + 8x = 10x

2x = 12

x = 6

Up to 5 visits, the non-member cost is better. At 6 visits, there's the same price. For more than 6 visits, the member cost is better.

H (t) = 2t - 2 g(t) = 4t + 5 Find (h(g(t))

ASHA 777 [7]

Answer:

$h(g(t))=8t+8$

Step-by-step explanation:

We are given the two functions:

$h(t)=2t-2\text{ and } g(t)=4t+5$

And we want to find:

$h(g(t))$

So, by substitution, we acquire:

$h(g(t))=2(4t+5)-2$

Distribute:

$h(g(t))=8t+10-2$

Simplify:

$h(g(t))=8t+8$
