Answer:

y=2x-2

you could use y=mx+b

Answer:

7-(-3)/-4-(-6)

10/2

y=5x

Step-by-step explanation:

Answer:

the slope is 5.

Step-by-step explanation:

the equation for slope is y2-y1/x2-x1

the points are (-4,7), (-6, -3)

label the points:

x1: -4

y1: 7

x2: -6

y2: -3

Now, plug it into the equation

-3-7/-6--4

-10/-2

the slope is 5

Answer:

16 inches by 32 inches or 1 1/3 feet by 2 2/3 feet

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

x+ 7.05 = 45.3

Subtract 7.05 from each side

x+ 7.05-7.05 = 45.3-7.05

x =38.25

Let x be the number

x+3.5 = -4.3

Subtract 3.5 from each side

x+3.5 - 3.5 = -4.3-3.5

x = -7.8

x is the cost of the drawing tablet

x+ 3.95 = 6.94  correct

The second equation add the total cost plus the cost of the drawing tablet  and sets it equal to the cost of the pencils.  This is not correct

6.94+x = 3.95   incorrect

Answer:

1. x=38.25

2. -7.8

3. the second option

Step-by-step explanation:

1. x+7.05=45.3

(move the constant to the right)

x=45.3-7.05

(calculate)

x= 38.25

(answer)

2.

(you subtract -4.3 by 3.5)

3.

(you can't use $6.94 + x = $3.95 because $6.94 is your total overall so you can only use that as your end result)

Step-by-step explanation:

(10-(-9)*-1)

Remember that 2 negative equal a positive. So -(-9) is positive.

(10+9*-1)

Then, PEMDAS is how you should finish this.

So, 9*-1 is -9

Then, 10-9 is 1

Answer:

The slope intercept form of (0,3) and (4,2) is y= -1/4x+3

Step-by-step explanation:

The distance from our y values from 3 to 2 is -1.

The distance from our x values is 4.

We can put these values as our slope and we know that the Y values are always rise and the x values are always run

Therefore we get y= -1/4x+3 (side note: The 3 is our y intercept, this means that the x value of the three is always 0. For example, in (0,6) the y intercept would be 6.

Answer:

35

Step-by-step explanation:

(-5)(-7) is a multiplication problem, so you would multiply -5 and -7 together to get 35 as two negatives make a positive

=====================================================

Explanation:

The given angle is ∅ = 300. This x value is between 270 and 360, so we're in quadrant IV (the southeast quadrant)

The rule to get the reference angle y for this quadrant is

Ф = 360-∅

This tells us the angle made with the positive x axis

Ф = 360-∅

Ф = 360-300

Ф = 60

A 60 degree angle forms with the positive x axis as shown in the diagram below.

Answer:

AC=22

Step-by-step explanation:

The measure of the Length of AC is; 35

We are given;

ac = 5x

ab = 12

bc = 3x + 2

ab + bc = ac

Thus;

12 + 3x + 2 = 5x

14 + 3x = 5x

Subtract 3x from both sides to get;

5x - 3x = 14

2x = 14

x = 14/2

x = 7

ac = 35

Answer:

  9/5

Step-by-step explanation:

The slope between the two points can be found by ...

  m = (y2 -y1)/(x2 -x1)

  m = (-16-2)/(-10-0) = -18/-10

  m = 9/5

The slope of the line is 9/5. Perhaps this is a match to choice A.

Answer: 9/5

m = (y2 -y1)/(x2 -x1)

 m = (-16-2)/(-10-0) = -18/-10

 m = 9/5

Answer:

60n-30

Step-by-step explanation:

you would do 15 * 4n

that would give you 60. since 15 *4 is 60 and then you would just put the n

15*2 equals 30. You would make it a negative 30 since it is a negative 2.

then you would combine them and get the answer

60n-30
