Solve the y for the equation 5x-2y=10

Answers

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for x

Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5

Answer:

y = (5/2)x - 5

Step-by-step explanation:

5x-2y = 10

Subtract 5x from both sides

-2y = 10 - 5x

Rearrange

-2y = -5x + 10

divide both sides by -2 to isolate y

y = (5x/2) + (10/-2)

y = (5/2)x - 5

b is a point between a and c where ac = 5x, ab = 12, and bc = 3x + 2. what is the measure of the length of ac?

Answers

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

We are told that b is between a and c. This means that;

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

Thus, ac = 5x = 5 * 7

ac = 35

Answers

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

Identify the reference angle Ф for each given angle, Ф.
When ∅=300°, Ф=

Answers

Answer: 60 degrees

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

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.

PLEASE HELP! MUCH APPRECIATED. MATH IS SO HARD :(

Answers

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)

(you subtract -4.3 by 3.5)

(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)
