Coordinates will be fine PLs ASAP cause I need this rn<br> 13 POINTS!!!

If the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

Given,

The vertices of the triangle = J(-3,-5), K(-2,2) and L(1,-4)

We know,

In reflection in y axis (x,y)  will become (-x,y)

Then the vertices of the reflection in y axis = J(3,-5), K(2,2) and L(-1,-4)

Draw the triangle using the vertices.

Hence, if the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

What is 5(x-2)-14x when x=4
nevsk [136]

Answer:

-46

Step-by-step explanation:

5 (x - 2) - 14x.   x=4

5 (4 - 2) - 14(4)  (distribute)

20 - 10 - 14(4)   (multiply)

20 - 10 - 56    (subtract and solve.)

10 - 56 = -46 - solution

hope this helps (:

The product of a number and -2/3 is -9/10<br> (20 Points)<br> What is the number?
poizon [28]

Answer:

\large\boxed{n=\dfrac{27}{20}}

Step-by-step explanation:

\text{Let}\ n\ \text{is a number.}\\\\\text{The product of a number and}\ -\dfrac{2}{3}\ \text{is}\ -\dfrac{9}{10}:\\\\-\dfrac{2}{3}\cdot n=-\dfrac{9}{10}\\\\-\dfrac{2n}{3}=-\dfrac{9}{10}\qquad\text{change the signs}\\\\\dfrac{2n}{3}=\dfrac{9}{10}\qquad\text{cross multiply}\\\\(2n)(10)=(3)(9)\\\\20n=27\qquad\text{divide both sides by 20}\\\\\dfrac{20n}{20}=\dfrac{27}{20}\\\\\boxed{n=\dfrac{27}{20}}
