Answer:

y = (3/-2)x + 4.

Step-by-step explanation:

slope intercept form is y = mx + b

1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.

2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).

3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.

8/9 divided by 2/3 is 1 1/3

does 9/20 and 18/30 form a proportion

Answers

Answer:

No, they don't.

Step-by-step explanation:

I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.

18 ÷ 9 = 2

30 ÷ 20 = 1.5

The quotients aren't the same. Same thing if you convert the fractions to decimals:

9 ÷ 20 = 0.45

18 ÷ 30 = 0.6

This means the two values do NOT form a proportion.

Hope this helps! Have a great day!

Answer:

No.

Step-by-step explanation:

9/20=18/30

9*30=20*18

120=360

Select the solution(s) of log2x=1−log(x+4).

Answers

Step-by-step explanation:

log2x = 1 - log(x+4)

log2x = log10 - log(x+4)

log2x = log[10/(x+4)]

2x = 10/(x+4)

2x(x+4) = 10

2x² + 8x - 10 = 0

÷2 both sides of equation

x² + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5, 1

x isn't be -5 because logA, A need to be > 0

So, x value is 1

-3(2x - 3) = 33 = ?

4x + 3x + 2x = 180 = ?

Answers

Answer:

-4x-6x=-20=

x=2

-3(2x-3)=33=

x=-4

4x+3x+2x=180

x=20

Step-by-step explanation:

-4x-6x=-20                                

-4+(-6)=-10x

-10x=20 (divide both by 10)

x=-2 (divide by -1 to get positive)

x=2

-3(2x-3)=33

-6x+9=33

     -9 .  -9

-6x=24 (divide both by -6)

x=-4 (divide by -1 to make positive)

4x+3x+2x=180

(combine like terms)

9x=180 (divide both sides by 9)

x=20
