Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51

Answers

Answer:

The solution of the equation    y = 36

Step-by-step explanation:

Explanation:-

Given equation -3x-y =-51

Given that x =15 in equation -3x-y=-51

                 ⇒        - 3(15) - y = -51

                ⇒         - 15 - y =-51

                 ⇒         -15+ 51 = y

               ⇒            y = 36

Answers

Answer:

( 1, 5 )

x = 1

y = 1

Step-by-step explanation:

y = x + 4

2x + 3y = 17

Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.

2x + 3y = 17

2x + 3 ( x + 4 ) = 17

Distributive Property

2x + 3 * x + 3 * 4 = 17

2x + 3x + 12 = 17

Combine Like Terms ( 2x and 3x)

5x + 12 = 17

Subtract 12 on both sides of the equation

5x + 12 - 12 = 17 - 12

5x = 5

Divide by 5 on both sides to isolate the variable

5x/5 = 5/5

x = 1

Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"

y = x + 4

y = 1 + 4

y = 5

x = 1

y = 5

( x, y )

solve . 15 - 10x = 5(x + 9) show your work

Answers

Answer:

x= -2

Step-by-step explanation:

Let's solve your equation step-by-step.

15−10x=5(x+9)

Step 1: Simplify both sides of the equation.

15−10x=5(x+9)

15+−10x=(5)(x)+(5)(9)(Distribute)

15+−10x=5x+45

−10x+15=5x+45

Step 2: Subtract 5x from both sides.

−10x+15−5x=5x+45−5x

−15x+15=45

Step 3: Subtract 15 from both sides.

−15x+15−15=45−15

−15x=30

Step 4: Divide both sides by -15.

−15x/-15 = 30/ -15  

x= −2

Answers

Answer:

14 units²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 7 and h = 4 , so

A = [tex]\frac{1}{2}[/tex] × 7 × 4 = [tex]\frac{1}{2}[/tex] × 28 = 14 units²

What is y? Helppp thank you !

Answers

Answer:

y = 42

Step-by-step explanation:

Since QT is a midsegment then it is half of RS , that is

QT = [tex]\frac{1}{2}[/tex] RS, substitute values

y = [tex]\frac{1}{2}[/tex] (y + 42) ← multiply both sides by 2 to clear the fraction

2y = y + 42 ( subtract y from both sides )

y = 42

Y= 42 this is the answer hope it helps

B.

C.
2y =-3x + 6
D.
2y + 3x = 6
E.
y=-2x + 3

Answers

Answer:

Its would be E

Step-by-step explanation:

1.5x + 3 = -2x + 3    -1.5x = -2x   0.5x = 0  x = 0

Which is 0,3 and it’s only one solution.

The equation that gives the solution together with y = -1.5x + 3 is

y = -2x + 3

Option E is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 is an equation.

We have,

y = -1.5x + 3 ____(1)

y = -2x + 3 ____(2)

From (1 ) and (2) we get,

-2x + 3 = -1.5x + 3

-2x + 1.5x = 3 - 3

-0.5x = 0

x = 0

Now,

y = -2x + 3

y = 0 + 3

y = 3

Thus,

The solution is (0, 3).
