Find the equation of the line passing through (2,-1) and parallel to the line 2x-y=4

Mathematics

Answer:

y = 2x - 5

Step-by-step explanation:

The equation has to have the same slope -- in this case, it is 2 -- to be parallel to 2x - y = 4.

Now we have y = 2x - k.

Then, we plug in the coordinates to our new equation to solve for k.

-1 = 2(2)-k

-1 = 4-k

k = 5

So the final equation would be y = 2x - 5

What is the equation of the line x–3y=18in slope-intercept form?
masha68 [24]

Answer:

the answer would be done like this

Step-by-step explanation:

you have to get y by itself so you would need to move the x to the right of the equal sign

once you move anything to the opposite side it switches, so positive becomes negative vice versa

-3y=-x+18

you need to make sure you have positive 1 y so you would divide y by -3 to make it 1

everything else is multiplied by -3 as well

so the answer would be y=⅓x-6

Hattie accepted a job as a makeup artist after being offered a $550 signing
Radda [10]

The equation would be y=32x+550. 32 an hour is represented by 32x since she earned 32 an hour. 550 is the extra amount she is getting paid.

I hope this helps.

Write the standard equation of the circle shown.
zysi [14]

Answer:

b

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← r is the radius

The circle shown is centred at the origin and has a radius of 5, thus

x² + y² = 5² ⇒ x² + y² = 25 → b

I need geometry help please.
irina1246 [14]

Lets remember the property "alternative-interior angles" when we have parallels lines:

Given two paralles lines, the following is true:

In our question, we have:

We know that the angles J + P + K=180

So, the triangles have all the angles the same, so they are similar by angle-angle-angle, and they have one side congruent, AC=CD, so the triangles are congruents.
