Answer:

x = 2

y = 4

Step-by-step explanation:

<em><u>Since it gives you the "value" of y, just plug one of them into an equation:</u></em>

y = x + 2

3x - 2 = x + 2

<em><u>Now, subtract x from both sides:</u></em>

3x - 2 = x + 2

-x         - x

__________

2x - 2 = 2

<em><u>Then, add 2 to both sides:</u></em>

2x - 2 = 2

    + 2  + 2

________

2x = 4

<em><u>Finally, divide both sides by 2:</u></em>

2x = 4

x = 2

<em><u>Now to get y, just plug in 2 for x in an equation:</u></em>

y = x + 2

y = 2 + 2

y = 4

kelli and her faimly went to the beach for a vacation. they drove 293 miles 7 hours to get theredid they drive each hour
Inessa [10]
Ok so, Since Kelli and her family drove a total of 293 miles in 7 hours, then your equation should be \frac{293miles}{7hrs} 
Now, since you have your ratio you divide 293 by 7 in order to get how many miles were driven in one hour
\frac{293}{7} = 41.85714286 miles/hr

Find the distance between points M(-7,5) and Z(2,-3)
julsineya [31]

Hey there! I'm happy to help!

To find the distance between two points, you find the difference between the x values, square that, find the difference between the y values, square that, add the two numbers you got, and then find the square root.

We find the difference between the x values.

-7-2=-9

Square it.

-9²=81

We find the difference between the y-values.

5--3

5+3=8

We square it.

8²=64

We add the numbers we got.

81+64=145

We square root.

√145≈12.04

This formula comes from the Pythagorean Theorem! Now you can find the distance between any two points! Have a wonderful day! :D

Can someone explain how to find z?
Julli [10]

The vlaue of z is 27°

Step-by-step explanation:

Given,

The angle is 63°

To find the value of z

We know that the diagonals of rhombus perpendicularly bisect each other.

Again,

z+63°+90° = 180° [ sum of all the triangle is 180°]

or, z = 27°
