Answer:

x = 8

I dunno what the question is in the first place, but I assume you are solving for x.

Step-by-step explanation:

The two given angles are equivalent because they are parallel and they have a line that intersects.

The line creates two angles on each side of each line, which is 120 or 60 because there are 180 degs on a straight line.

The obtuse side is 120, and the -8 + 16x is also on an obtuse angle, showing that they are equal.

120 = -8 + 16x

128 = 16x

8 = x

x = 8

Answer:

X = 8 And y = 1/5

Step-by-step explanation:

add equaction i and education ii,

2 -5y = 1

2x +5y = 17

------------------

2+2x = 18

or, 2x = 18 - 2

or X = 16/2

or X = 8

Again from equation i,

2 - 5y = 1

or, -5y = 1 - 2

or, -5y = -1

or, y = -1/-5 (cut the subtraction sign)

or, y = 1/5

Alan needs to drive 400 miles to reach Madison. He is driving at a constant speed of 55 miles per hour. The function y = 400 − 5

lord [1]

Question is not written properly but i think you are looking for the table of given equation y=400-55x. So I will explain about how to get that.

number of hours can't be negative so that means x must be 0 or more.

like x=0,1,2,3,...

we just have to plug these x-values into above equation to find the y-value in order to calculate table.

I will show you calculation for x=2

y=400-55x=400-55*2=400-110=290

so the point in table will be (2,290)

similarly we can find more point and get final table as shown below:
