Which of these ordered pairs is a solution of 3x−y=12? Choose all that apply.

Answer:

x = 96

z = 25

Step-by-step explanation:

x and 84 are supplementary angles.

this means that they add together to make 180.

using this, you can make the following equation:

x + 84 = 180

subtract 84 from both sides of the equation

x + 84 - 84 = 180 - 84

x = 180 - 84

x = 96

84 and 3z + 9 are vertical angles

vertical angles are equal.

using this, you can make the following equation:

84 = 3z + 9

subtract 9 from both sides of the equation

84 - 9 = 3z

75 = 3z

divide both sides of the equation by 3

75/3 = 3z/3

25 = z

Answer:

x > 50

Step-by-step explanation:

Let

x = number of bags of popcorns to sell

Price of each bag of popcorn = $3

You hope to earn at least $150 for the trip.

At least in inequality = >

The inequality is

Price × quantity of popcorns to sell > 150

3x > 150

Divide both sides by 3

x > 150 / 3

x > 50

Answer:

1. 13/15

2. 4/13

3. 3/4

4. 1 1/18

5. 1/4

6. 3 1/6

7. 1

Step-by-step explanation:

i will use the last one as an example, first reduce, so you would find the common denominator, in this case its 6, so you simplify 6/30 to 1/5. then you have 4/5+1/5, so since u have the same denominator, you can add the two numerators above the common denominator, so it would look like 4+1/5. then add the numbers. so you are left with 5/5 which in other words is 1. i hope this helps!

Answer:

About $78

Step-by-step explanation:

The company is not complete. The question is to estimate the sales 8 weeks after release. To do that, we will substitute t = 8 into the modeled function s=10√5t+15

s = 10√5(8) + 15

s = 10√40 + 15

s =10(6.32)+15

s = 63.2+15

s = 78.2

Hence the sales after 8weeks is about $78.

So first you want to number your graph

The first number you want to graph is the first one on the x line, If you numbered in ones it should be 4 to the left from the center

Next graph the 2nd number on the y line, draw a line and connect the -4 and the 7

Answer:

7.9 units

Step-by-step explanation:

You are required to find the distance between the points P and Q whose coordinates are given:

P (0, 0), Q(-4, 7)

[tex] QP= \sqrt{ {( - 4 - 0)}^{2} + ( {7 - 0})^{2} } \\ \\ = \sqrt{( - 4) ^{2} + {(7)}^{2} } \\ \\ = \sqrt{16 + 49} \\ \\ = \sqrt{63} \\ \\ = 7.93725393 \\ \\ = 7.9 \: units[/tex]

Answer:

slope is -2/5

y-intercept is 4

Answer:

See Below

Step-by-step explanation:

Ok, so slope intercept form is:

y = mx +b

Where m = slope and b = your y-intercept

lets line them up

   y = mx + b

y =-2/5 x + 4

Notice that the m and b are lined up each corresponding #.

Therefore,

m = -2/5

B = 4

Slope = -2/5

y - intercept = 4

Answer:

Im pretty sure slope is 21 and y intercept is 15

The slope is 21 and the y-intercept is -33 of the graph of function h.

A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.

It represents the line's slope-intercept form, which is written as y = mx+ c.

The function is given in the question below as

f(x) = –7x + 9

⇒ f(x) = –7x + 9

Add 2 to the input of f to create a new function g,

⇒ g(x) = –7x + 9 + 2

⇒ g(x) = –7x + 11

Now, multiply the output of function g by –3 to create function h.

⇒ h(x) = (–7x + 11) × -3

⇒ h(x) = 21x - 33

Compare to the line's slope-intercept form,

Therefore, slope = 21 and y-intercept = -33

Answer:

[tex]P: (-2,4)[/tex]

[tex]P' : (-4,-2)[/tex]

Step-by-step explanation:

Given

[tex]P: (-2,4)[/tex]

Required

Rotate 90 degrees counterclockwise

Show both points on graph

[tex]P: (-2,4)[/tex]

When a point is rotated counterclockwise by 90 degrees, the new point is:

[tex]P':(-y,x)[/tex]

In

[tex]P: (-2,4)[/tex]

[tex]x = -2[/tex]

[tex]y = 4[/tex]

Hence:

[tex]P':(-y,x)[/tex]

[tex]P' : (-4,-2)[/tex]
