20. Write the following equation in slop intercept form. -4x-3y=-18.
21. Write the following equation in slope intercept form. -2x+3y=21

please show your work and thank you.

Answers

Answer 1

Step-by-step explanation:

slope intercept form y=mx+b

you just need to move the letters and numbers around to match this.

-4x-3y=-18

add 4x to both sides of the equal sign

-3y =4x-18

divide by negative 3 on both sides

y = -4/3x + 6

21. -2x+3y=21

add 2x to both sides

3y = 2x + 21

divide by 3 on both sides

y = 2/3x +7

Step-by-step explanation:

Answer:

∠ C ≈ 22.6°

Step-by-step explanation:

Since Δ ABC is right at B

Using the sine ratio in the right triangle

sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{5}{13}[/tex] , then

∠ C = [tex]sin^{-1}[/tex] ( [tex]\frac{5}{13}[/tex] ) ≈ 22.6° ( to 1 dec. place )

A. x= 13 + 20
B. X = -2.75 +3
C. X = 2.5+ 3

The coins can be distributed in the following manner -

2 quarters (2 x 25) + 2 dimes (2 x 10) + 1 nickel (5) = $0.75

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Michele who has 5 coins Worth 0.75 in all.

We can distribute the coins in the following manner -

2 quarters (2 x 25) + 2 dimes (2 x 10) + 1 nickel (5) = $0.75

Therefore, the coins can be distributed in the following manner -

2 quarters (2 x 25) + 2 dimes (2 x 10) + 1 nickel (5) = $0.75

- Given: C is the midpoint of AE
C is the midpoint of BD
AE = BD

Prove: AC = CD

Answers

A midpoint is a point that bisects a line into two equal parts.

Given that  C is the midpoint of AE, hence;

AC + CE = AE ........ 1

Similarly, if C is the midpoint of BD, then;

BC + CD = BD................... 2

If AE = BD, then we will equate 1 and 2 to have:

AC + CE = BC + CD

Also since CE = BC, the equation becomes

AC + CE = CE + CD

AC = CD (Proved)

(b) It takes 37 pounds of seed to completely plant a 4-acre field. How many pounds of seed are needed per acre?​

Answers

Answer:

9.25 lbs

Step-by-step explanation:

37 is the amount for 4 acres or 4a:

37  = 4a

Isolate and find a by dividing both sides by 4:

4a = 37

4a ÷ 4 = [tex]\frac{37}{4}[/tex]

a = [tex]\frac{37}{4}[/tex] or 9.25 lbs

Answers

Answer:

Step-by-step explanation:

The triangle’s angles add up to 180°

so 180 - (5x - 2) = the another one interior angle

180 - 5x + 2

182 - 5x

and then 2x + 76 + (182 - 5x) = 180

2x + 76 + 182 - 5x = 180

258 - 3x = 180

78 = 3x

x = 26

so 2x = (26)(2) = 52

5x - 2 = (5)(26) - 2 = 128
