Remember you can do anything to an equation as long as you do it to both sides

pemdas
first, subsitue z for the blank
(4z)-(1+8x2)=3
simplify
(4z)-(1+16)=3
(4z)-(17)=3
4z-17=3
add 17 to both sides
4z+17-17=3+17
4z+0=20
4z=20
divide both sides by 4
4z/4=20/4
1z=5
z=5
the blank is 5

What is the measure of angle x? . Enter your answer in the box <br> X=​
marshall27 [118]

Answer:

83 degrees

Step-by-step explanation:

The angles 56 and 41 plus the one in between should add up to 180 degrees. So you do 180 - 56 - 41 = 83.

83 and x are vertical angles so they are the same measure.

<x = 83 degrees

For the proportional relationship y = -5x, what is the ratio of vertical change to horizontal change? Will the graph of the line
NeTakaya
The given proportional relationship is y = -5x.
Therefore the ratio
y/x = -5 = -5/1

If x changes by 1, then y/x = y/1 = -5.
This means that y changes by -5 when x changes by 1.
The ratio of vertical change is -5:1

The standard equation for a straight line is
y = m*x + c
where
m = the slope,
c = the y-intercept.

Therefore the given relationship is a straight line with a negative slope of -5. This means that y decreases as x increases.

Answer: C
-5:1
The graph decreases from left to right.
