Answer:

$2x+ \frac{156}{5}$

Step-by-step explanation

simplify step-by-step.

2(x+7)−(−18+

)

Distribute the Negative Sign:

=2(x+7)+−1(−18+

)

=2(x+7)+(−1)(−18)+−1(

)

=2(x+7)+18+

−4

Distribute:

=(2)(x)+(2)(7)+18+

−4

=2x+14+18+

−4

Combine Like Terms:

=2x+14+18+

−4

=(2x)+(14+18+

−4

)

=2x+ $\frac{156}{5}$

There is a line that includes the point (2, 10) and has a slope of 1. What is its equation in

rjkz [21]

Answer:

The line is y=1x+8

Step-by-step explanation:

We can use point-slope form of a line to make an equation. Point-slope form is as follows:

y-y₁=m(x-x₁)

**The variables y₁ and x₁ are where we will plug in our given coordinates and the variable m is your slope.

1. Plug in the given info:

y-10=1(x-2)

2. Distribute the 1:

y-10=1x-2

3. Add 10 to both sides:

y=1x+8

The coordinates of LMN are L (4,5), M (5,-2), and N (0,0). If the triangle is rotated 270° about point N, what are the coordinat

tester [92]

Answer: (-2,-5)

Step-by-step explanation:

The rotation rule for rotating a figure about $270^{\circ}$ is given by :-

$(x,y)\to (y,-x)$ , where (x,y) is the coordinates for pre-image and (y,-x) is the coordinates for image. (1)

Given : The coordinates of LMN are L (4,5), M (5,-2), and N (0,0).

If the triangle is rotated 270° about point N

Then, the coordinates of M , will be :

$(5,-2)\to (-2,-5)$ (Using the rule described in (1))

Hence, the coordinates of M after rotated 270° about point N=(-2,-5).
