Answer:
x=1, y=8
Step-by-step explanation:
Plug y=8x into y=10x-4.
8x=10x-4
Subtract 10x from each side.
-2x=-2
Divide each side by -2.
x=1
Plug x=1 into y=8x.
y=8(1)
y=8

Answer:
proably and acute angle
Step-by-step explanation:
acute angles are angles that are less than 90 degrees and the picture obviouly shows an angle that is less than 90
The answer would be:
The y-intercept is 1 space higher.
This equation is a y=mx+b and if you didn't already know, the +b is the y-intercept. It's where the equation intersects with the y line. Since the original equation didn't have one, it means it passed through the origin and now that it has one, the intersection would be (0,1). Because of this, the whole equation would shift up 1 whole unit.
Answer:
fourth option
Step-by-step explanation:
The mean is calculated as
mean = 
= 
= 
= 23.6 ( to 1 dec. place )
The median is the middle value of the data set. If there is no exact middle then it is the average of the values either side of the middle.
15 16 21 23 25 25 25 39
↑ middle
median = 
= 
= 24
The mode is the value that occurs most often, that is 25
Thus
mean = 23.6 , median = 24 , mode = 25
