Answers

Answer:

y=-3x+7

Step-by-step explanation:

Rise/run

To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.

As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.

Plug your answers in and your equation should be y=-3+7.

You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.

Hope this helps :)

Which number sentence represents the Commutative Property of Addition?

44 + 1 = 45
44 + 1 = 45

(16 + 2) + 18 = 16 + (2 + 18)
(16 + 2) + 18 = 16 + (2 + 18)

56 + 0 = 56
56 + 0 = 56

32 + 9 = 9 + 32

Answers

32 + 9 = 9 + 32 is the answer

The number which represent represents the Commutative Property of Addition will be;

⇒ 32 + 9 = 9 + 32

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expressions are,

44 + 1 = 45

(16 + 2) + 18 = 16 + (2 + 18)

56 + 0 = 56

32 + 9 = 9 + 32

Now,

We know that;

The rule of the Commutative Property of Addition is,

⇒ a + b = b + a

Hence, The correct number which represents the Commutative Property of Addition is,

⇒ 32 + 9 = 9 + 32

If l || m, m7 = 2x and m2 = x, then what is the measure of angle 2?

90°
30°
120°
60°

Answers

120
Since we first have to find out what x would be in both situations and then do an equation to figure out angle 2

An l || m, m7 = 2x and m2 = x, then what is the measure of angle 2 is 30°.

To find the measure of angle 2, use the properties of parallel lines and transversals.

Given that line l is parallel to line m, and we have two angles formed by a transversal intersecting these lines, angles 2 and 7.

are given that m7 = 2x and m2 = -1.

Since lines l and m are parallel, alternate interior angles are congruent. Therefore, angle 2 and angle 7 are congruent.

m2 = m7 (alternate interior angles are congruent)

Since m7 = 2x, substitute:

m2 = 2x

But, we are also given that m2 = -1, so set up an equation:

-1 = 2x

Now, solve for x:

x = -1/2

Now that have the value of x, find the measure of angle 2:

m2 = 2x

m2 = 2(-1/2)

m2 = -1

Therefore, the measure of angle 2 is -1 degree. However, it's worth noting that angles are typically measured as positive values, so the answer in this case would be 1 degree (considered as an acute angle). None of the multiple-choice options provided matches this answer exactly, but the closest one would be 30°.

Answer:

okay sorry but its roofs, not rooves but the answer is

Step-by-step explanation:

2 3/5 divided by 3 1/2 which equals 13/5 divided by 7/2

13/5 times 2/7, which equals 26/35. This stands as 26/35 box of nails per roof. Altogether you get 5.94, which you would have to round to about 6 boxes.

a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.

Answers

Answer:

2x - 30

Step-by-step explanation:

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

Answer = 2x - 30

(5x-12)-(3x+18)

Simplified becomes 2x-30
