I would just like to point out that you solved your first equation incorrectly.

I didn't try finding the correct answer but -23 + 5 = -18 not 18, you forgot the negative sign!!!

Find the slopes of the linear functions.
y = -2x + 7
The slope of the line given by the linear equation is
-2v.
The slope of the line shown in the graph is V-14

Answers

Answer:

Find the slopes of the linear functions.

On a coordinate plane, a line goes through points (0, 6) and (6, 0). Y = negative 2 x + 7.

The slope of the line given by the linear equation is

✔ -2

The slope of the line shown in the graph is

✔ -1

Step-by-step explanation:

on edge 2020

The slope of linear Equation is -2.

what is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y= -2x+ 7

Now, we know the standard form of slope- intercept form

y= mx+ b

where m is slope and b is the y- intercept

Now, Comparing it with given equation we get

slope, m= -2

The circumference of a circular garden is 75.36 feet. What is the radius of the garden

Answers

Answer:

12 rounded to a whole number.

Step-by-step explanation:

75.36 divided by pi (3.14159) = 23.987. this is diameter (the length from one side of a circle to the other).

but we need to find the radius. the radius is half way across a circle.

23.987 divided by 2 = 11.993.

round this to a significant whole number and you get 12.

The radius of the garden is,

⇒ r = 12

We have to given that;

The circumference of a circular garden is,

⇒ C = 75.36 feet.

Since, We know that;

The circumference of a circle is,

⇒ C = 2πr

Substitute given values,

⇒ 75.36 = 2 × 3.14 × r

⇒ 75.36 = 6.28 r

⇒ r = 12

Thus, the radius of the garden is,

⇒ r = 12

The ratio table below shows the relationship between the number of bricks in a wall and the length of the wall.
Brick Wall

6 3
8 4
12 6
18 9
When the number of bricks is multiplied by 2, the length is multiplied by
1.
2.
3.
6.

Answers

Answer:

The length will be multiplied by 2.

Step-by-step explanation:

By looking at the first and third ratio, we know that the no. of birck have been multiplied by 2 and the length has also been multiplied by 2 .

So when the number of bricks is multiplied by 2, the length is multiplied by 2

Answer:

Step-by-step explanation:

Using the table we observe the points

(6, 3) and (12, 6)

The number of bricks doubled

6*2 = 12, and

The length is doubled accordingly

3*2 = 6

So the answer is 2

Which of the following equations is equivalent to 3(a + 4) – 5(a – 2) = 22?
8a + 22 = 22
8a + 2 = 22
-2a + 2 = 22
-2a + 22 = 22

Answers

-2a + 22 = 22 is the answer

Answer:

-2a + 22 = 22

Step-by-step explanation:

Distribute the 3 to both terms in (a + 4) and -5 to both terms in (a – 2) to get 3a + 12 – 5a + 10 = 22. Simplify to get -2a + 22 = 22.

solve 8 + 7x = 14
solve y + (-12) = 10

Answers

Answer:First one is x=1

second is y=22

Step-by-step explanation:

Answer:

[tex]x = \frac{6}{7}[/tex] y = 22

Step-by-step explanation:

For first equation:

Subtract 8 from each side, so it now looks like this: 7x = 6Divide each side by 7 to cancel out the 7 next to x. It should now look like this: [tex]x = \frac{6}{7}[/tex]

For second equation:

Simplify: y - 12 = 10Add 12 to each side, so it now looks like this: y = 22

Line L is Parallel to Line M. Find the value of x and y (pls help asap)

Answers

10x-17 = 8x+1 (vertical angles)
2x = 18
x = 9

plug in to find angle measure
8(9)+1 = 73

73 + 6y + 29 = 180 (supplementary angles)
102 + 6y = 180
6y = 78
y = 13

The value of the variables 'x' and 'y' will be 9 and 13, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Line L is Parallel to Line M.

The vertical opposite angles (10x - 17) and (8x + 1) are equal. Then the equation is given as,

10x - 17 = 8x + 1

Simplify the equation, then the value of 'x' will be given as,

10x - 8x = 17 + 1

2x = 18

x = 9

The angle (6y + 29) and (8x + 1) are the supplementary angles. Then equation is given as,

6y + 29 + 8x + 1 = 180

6y + 29 + 8(9) + 1 = 180

6y + 102 = 180

6y = 76

y = 13

The value of the variables 'x' and 'y' will be 9 and 13, respectively.

- 1/2 y = 1+10 (by taking lcm)

[tex]\frac{-1}{2}[/tex] x 2y = 11

y = -11

[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]

5. m∠A = 26

6. m∠D = 118

7. m∠E = 43

8. m∠H = 85

Step-by-step explanation: complementary= 90 supplementary = 180

5. (2x - 8) + (4x +4) = 90

6x - 12 = 90

6x = 102

x = 17

m∠A = 2x - 8

m∠A = 2(17) - 8 = 26

6. (2x + 18) + (5x + 8) = 180

7x + 26 = 180

7x = 154

x = 22

m∠D = 5x + 8

m∠D = 5(22) + 8 = 118

7. (2x + 15) + (3x + 5) = 90

5x + 20 = 90

5x = 70

x = 14

m∠E = 2x + 15

m∠E = 2(14) + 15 = 43

8. (5x - 20) + (4x + 7 ) = 180

9x - 27 = 180

9x = 207

x = 23

m∠H = 4x -7

m∠H = 4(23) - 7 = 85

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?

Answers

Answer:

$4.7

Step-by-step explanation:

step one:

Let the cost be y

to solve for the cost of a movie ticket, we need to solve the expression

y=2.75+0.10x

step two:

given that x is the number of years between 1980-2000

the number of years is 20years

put x= 20 in the expression for the cost we have

y=2.75+0.10(20)

y=2.7+2

y=$4.7
