Hi there!

We could use elimination to find the y-coordinate of those two equations.

First multiply the first equation by 2, so that we could get rid of x.

2 (5x + 2y = 7)
10x + 4y = 14

Then multiply the second equation by 5.
5 ( -2x + 6y = 9)
-10x + 30y = 45

Add the two equations.

          10x + 4y = 14
+      - 10x + 30y = 45
------------------------------
                    34y = 59
                        y = 1.74

The y-coordinate is 1.74. 
Hope this helped! :)

Find the unit rate and slope of the graph (ignore what I put down)
Vilka [71]

Answer:

slope: 5/7

0.714 mile per hour

Step-by-step explanation:

slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)

Mile per hour: 5/7 cross multiply with x/1, make into an equation:

7x=5 x 1

7x = 5

x = 0.714

<h2><em><u>16h2</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>4h</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>42</u></em></h2>

Step-by-step explanation:

(4h + 6)(4h − 7)

= 4h(4h - 7) + 6(4h-7)

= 16h2 - 28h + 24h - 42

= <em><u>16h2 - 4h - 42 (Ans)</u></em>

PLZ HELP
Alex

Answer:

The correct option is C ) 109.5°

Therefore,

m\angle E=109.5\°

Step-by-step explanation:

Given:

In Triangle DEF

d = 10

e = 18

f = 12

To Find

angle E = ?

Solution:

In Triangle DEF , Cosine Rule says

\cos E=\dfrac{f^{2}+d^{2}-e^{2}}{2fd}

Substituting the values we get

\cos E=\dfrac{12^{2}+10^{2}-18^{2}}{2\times 12\times 10}

\cos E=\dfrac{-80}{240}=-\dfrac{1}{3}

Therefore,

\angle E=\cos^{-1}(-0.3333)

m\angle E=109.5\°       ............As it is in Second Quadrant

Therefore,

m\angle E=109.5\°
