ILL GIVE BRAINIEST find the solption for each system of equations using substitution. check ur solution in both original equations and make sure equations are in slope intercept form before u set them equal

y= -2x+6 and y=3x-4


check:

Answer:

D

Step-by-step explanation:

y_2 - y_1 / x_2 - x _1

4 - 2 / 3 - (-1) = 2/4 = 1/2

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2

hope this helps :)

Answer:

[tex]168[/tex]

Step-by-step explanation:

Because we are missing the options to this question we will have to answer this question using what we know.

[tex]7\times3\times8[/tex]

Solve

[tex]7\times3=21[/tex]

[tex]21\times8=168[/tex]

[tex]=168[/tex]

All you have to do now is find the expression that also equals to 168, when you do that option is your answer.

Hope this helps.

Solution:

Rewrite 3 ≥ y - 2 for easier calculation:

y - 2 ≤ 3

Move the term:

y ≤ 3 + 2

y ≤ 5

When graphing the solution, filled dot (black arrow) is used for ≤ and ≥ while empty dot (white arrow) is used for < >

Answer:

6x + 2

Step-by-step explanation:

The area of a square is side length times itself.

In this problem, the area of one square is:

x², or x * x. So the side length of each square must be x.

In the rectangular shape, the area would be top * side. The side is equal to x because "side" is equal to the sides of the other squares (because a square's sides are all the same).

Plugging that into the equation, top * x = x, so the top must be 1.

There are 5 "full-length sides" on the two "full" squares on the left. Then, in the last skinny rectangle, there are two "tops", and one "full-length side".

Substitue the values of each side.

5x + 1 + 1 + x = 6x + 2

Answer:

The graph is not a function.

Step-by-step explanation:

Using the "vertical line test" to attach a vertical line to each of the points on the graph, we will find that the vertical line that passes through (0,0) has ot one, but two points on it. Remember, if the vertical line passes through more than one points, the graph is not a function. As we know, the vertical line passes through two points, those being (0, -4) and (0, -3). So, we can conclude that the graph is not a function.

Answer:

112,5°

Step-by-step explanation:

angle of WXZ + angle of ZXY = 180

180 / 8 = 22,5

5 × 22.5 = 112,5 = angle of WXZ

There you go, hoped it helped!

Answer:

A, d

Step-by-step explanation:

A) reflection, A) dilation

Step-by-step explanation:

To produce a congruent figure, the angle measures of the image and the side lengths of the image must be the same as the angle measures and side lengths of the pre-image. This means we cannot shrink, expand, or contract the figure; by definition, those transformations change the size. This leaves reflection.

To produce a similar, but no congruent figure, we must change the side lengths while keeping the angle measures preserved. Translations, reflections and rotations will move a figure but do not change the side lengths; dilation is the only choice that will change the side lengths.

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1

Answer:

21/40

Step-by-step explanation:

First you multiply the numerators (7 & 3) to get 21, then denominators (8 & 5) to get 40, unfortunately it cannot be reduced

In the scenario that it could be reduced, I was taught to cross reduce. lets say we had 2/8 x 4/6

You could divide by four for the 8 (denominator) and 4 (numerator) getting you 2/4 and 1/6

Then you do the same thing for 2 (numerator) and (6 denominator) so 2/2 is 1 and 6/2 is 3

Leaving you with 1/4 x 1/3 making it easier to multiply, and you don't have to reduce! Hope this helps!!
