Solve the system by graphing.<br><br> 3x+8y=16<br><br> 3x+8y=-64
Gnesinka [82]

<em>-3x-y=10</em>

<em>4x-4y=8</em>

<em>or</em>

<em>y = -3x - 10 </em>

<em>P(0,-10) and P(-2, -4) on this line: Plot and connect with the Line.</em>

<em></em>

<em> </em>

<em>y = x - 2</em>

<em>P(0, -2) and (2,0) on this line: Plot and connect with the Line.</em>

<em>P(-2,-4) is the ordered pair that is the solution for this system of EQs</em>

<em>On may CHECK by substituting x= -2 and y = -4 into the EQs of these Lines</em>

If m_2= x, m/3=40, and m24=5x + 14, what is mZ1?<br> A. 80 <br> B. 121<br> C. 21<br> D. 61
Alenkasestr [34]

Answer:

<h2>D. 61</h2><h2 />

Step-by-step explanation:

find x from the given triangle.

first step is to get x

add all inside angles = 180

∠2 + ∠3 + ∠4 = 180

x + 40 + 5x + 14 = 180

x + 5x = 180 - 40 - 14

6x = 126

x = 126 / 6

x = 21

substitute x=21 into angle 4

∠4 = 5x + 14

∠4 = 5(21) + 14

∠4 = 119

lastly, add ∠1 + ∠4 = 180

∠1 + 119 = 180

∠1 = 180 - 119

∠1 = 61°

therefore, the answer is D. 61
