Answer:
Step-by-step explanation:
Generally equation of a line is given as
y=mx+c
Then given the point (x, y)=(0,2)
Therefore x=0 and y=2
y=mx+c
2=m×0+c
2=0+c
Then, c=2
Then intercept is 2
Also given the point (x, y)=(3,4)
x=3 and y=4 and c=2
y=mx+c
4=m×3+2
4=3m+2
4-2=3m
2=3m
Then, m=2/3
Then, the slope of the graph is 2/3
y=mx+c
Now, m=2/3 and c=2
The general equation of the line becomes
y=2/3x+2
Multiply through by 3
3y=2x+6
Then this is the equation of the line
Answer:
x = 4.
Step-by-step explanation:
5x - 3.5 = 3x + 4.5
5x - 3x = 4.5 + 3.5
2x = 8
x = 4.
Answer:

Step-by-step explanation:
We are given with, in a tournament, Amanda scored 136 points in the first round and 127 points in the second round.
It is required to find the percent change between the two rounds. Percentage change between two rounds is given by :
So, the correct option is (A).
Answer:
p= -1
Step-by-step explanation:
5p-17p-9p+(-14)=7
5-17-9= -21p
-21p-14=7 add 14 to both sides
-21p=21 divide both sides by -21
p= -1
check 5(-1)-17(-1)-9(-1)+ (-14)=7
-5+17+9-14=7
8^2 + 2^2 = 64 + 4 = 68
(8 + 2)^2 = 10^2 = 100
The parentheses makes you add the numbers first then square it instead of squaring the numbers then adding
