Step-by-step explanation:

Step 1: Define Systems

-2x - y = 0

10x + y = -8

Step 2: Solve for x

Elimination

Step 3: Solve for y

Answer:

Step-by-step explanation:

-2x -y = 0

10x+ y= -8

8x = -8

x = -1

-10 + y = -8

y = 2

(-1, 2)

Step-by-step explanation:

slope is the number before x so slope here is 3/1 always add the 1 if its a whole number if its a fraction leave it.

y=mx+b

the y-intercept is always be so graphing is now easy

put a dot on the y-intercept so in this case it is 3 on the y-axis. then use rise over run. rise being up and down and run being left and right. so go up 3 then right 1 and put a dot there and connect your 2 lines to make a graph. if the number was -3/1 you go down 3 and right one then but thats just hypothetical

now to make a equation for a point you put it in y=mx+b.

Because its a 2,2

Step-by-step explanation:

The given equation is : 3x-2(x+3)=4(x-2)-73x−2(x+3)=4(x−2)−7

On solving this equation and applying the distributive property, we have

⇒3x-2x-6=4x-8-73x−2x−6=4x−8−7

⇒x-6=4x-15x−6=4x−15

Combining the like terms like terms consisting of x are solved together and the constants are solved together,

⇒x-4x=-15+6x−4x=−15+6

⇒-3x=-9−3x=−9

⇒x=3x=3

Answer:

y=1/4x+2

Step-by-step explanation:

im not sure what your problem is here, so im just gonna assume you have to put it into slope intercept form

As We can see that point J is on (-2,5) and L is on (-2,-2)

So we know that distance cannot be in negative, thus

Distance between J and L =5+2=7 units

JL=7

Answer:

y = 3x - 16

Step-by-step explanation:

In this question, we have to write an equation in slope-intercept form with the given information.

Slope-intercept form: y = mx + b

We already know our slope: 3

However, we don't know what are y-intercept (b) is.

To find this, plug the given information in the equation and solve for b:

-1 = 3(5) + b

-1 = 15 + b

Subtract 15 from both sides.

-16 = b

This means that our y-intercept will be -16.

Now, plug in our new information to the equation:

y = 3x - 16

The equation y = 3x - 16 will be your answer.

Answer:

y = 3x - 16

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope: 3

Points: (5, -1)

y = 3x + b

-1 = 3 ( 5 ) + b

-1 = 15 + b

b = -16

y = 3x - 16

Answer:

Yes, the given figure are similar but not congruent. All the edges are making angles of 90°.

Answer: simplifying

Step-by-step explanation:

2y + -10 = 6x

Reorder the terms:

-10 + 2y = 6x

Solving

-10 + 2y = 6x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 2y = 10 + 6x

Combine like terms: -10 + 10 = 0

0 + 2y = 10 + 6x

2y = 10 + 6x

Divide each side by '2'.

y = 5 + 3x

Simplifying

y = 5 + 3x

Answer: -6a-15b+12y+6

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Angle 3 and angle 6 are congruent because they are alternate interior angles. Angle 3 plus angle 1 is 180 degrees. So you just subtract 123 from 180 (180-123) and you get 57 degrees.

The measure of angle 6 is 57°

The correct answer is an option (A)

"The lines in the same plane that are at equal distance from each other and never meet."

"A line that passes through two lines in the same plane at two distinct points in the geometry. "

"The angles directly opposite to each other when two lines intersect in a plane."

For given question,

Line n and line p are parallel lines and line t is the transversal.

Here, angle 1 and angle 4 are opposite angles.

⇒ ∠1 = ∠4

We have been given that ∠1 = 123°

⇒ ∠4 = 123°

Also, angle 4 and angle 6 are interior angles on the same side of the transversal.

We know that each pair of interior angles on the same side of the transversal is supplementary.

⇒ ∠4 + ∠6 = 180°

⇒ 123° + ∠6 = 180°

⇒ ∠6 = 180° - 123°

⇒ ∠6 = 57°

Therefore, the measure of angle 6 is 57°

The correct answer is an option (A)

Answer:

x = 40

Step-by-step explanation:

The figure shows two similar triangles. Thus, the side lengths of similar triangles are proportional to each other. Therefore:

[tex] \frac{24}{24 - 15} = \frac{x}{x - 25} [/tex]

[tex] \frac{24}{9} = \frac{x}{x - 25} [/tex]

Cross multiply

[tex] 24(x - 25) = 9(x) [/tex]

[tex] 24x - 600 = 9x [/tex]

Subtract 24x from each side

[tex] - 600 = 9x - 24x [/tex]

[tex] - 600 = -15x [/tex]

Divide both sides by -15

[tex] 40 = x [/tex]

x = 40
