3 0

Answer:

Single Solution of 3.2 (16/5)

Step-by-step explanation:

3x = 8x -16 <--- I combine like terms.

-5x = -16

-16/-5 = x

x = 3.2

BTW Negative times a Negative equals a positive.

Write an equation in slope intercept form for the line that passes through (2,-2) and is parallel to y=-5/2x+5
DENIUS [597]

y=mx+b\\y=x-2

<em>Only y= x - 2 intercepts x-axis at 2 and y-axis at -2. Thus meaning that they intercept oppositely.</em>

<em>Find if both graphs are parallel, that means the equation must be false.</em>

<em />x-2=-\frac{5}{2}x+5<em />

<em>Multiply whole equation by 2 to get rid of the fractional 2.</em>

<em />2x-(2)(2)=-\frac{5}{2}(2)(x)+5(2)\\ 2x-4=-5x+10\\2x-4+5x-10=0\\7x-14=0\\7x=14\\x=2<em />

<em>Well, that doesn't seem to be parallel. This is called one solution answer. Both graphs intercept at (2,0). There are no linear graphs that intercept at (2,-2) except for y = x-2 so there are no graphs with (2,-2) that are parallel to the equation y = -5x/2+5 </em>

Answer all 4 please
FrozenT [24]
1)
180 - (37 + 90) = 180 - 127 \\ = 53
2)
(180 - 15) \div 2 = 165 \div 2 \\ = 82.5
each of other angles measures 82.5 degrees

3)
180 - (42 + 20) = 180 - 62 \\ = 118
4)sorry I don't know the last one
