hello :
Step-by-step explanation:
look the solution :
Answer:
B
Step-by-step explanation:
<em>y</em><em>=</em><em>kx</em><em>+</em><em>m</em>
<em>k</em><em>=</em><em>y2</em><em>+</em><em>y1</em><em> </em><em>/</em><em> </em><em>x2</em><em>+</em><em>x1</em><em> </em>
(3,5) and (7,9)
k=(9-5)/(7-3)=4/4=1
Now we want to find out what <em>m</em><em> </em>is. This is by inserting a point in the equation of the line y=kx+m.
so I'll pick (3,5)
5=1×3+m
m= 2
To check if it's correct we could try it with the other point, (7,9).
9=1×7+m
m=2
Therefor the equation would be. y=1x+2
Step-by-step explanation:
If two lines have the same slope and the same y-intercept, there are infinite solutions.
If two lines have the same slope and different y-intercepts, there are zero solutions.
Otherwise, if the two lines have different slopes, then there is one solution.
The slope of the first line is 3/8. The slope of the second line is 16/32 = 1/2. The slopes are different, so there is only one solution.
Answer:
22.5 degrees
Step-by-step explanation:
First angle = n
Second angle = x
Third angle = m
n = 30 + x
m = 2(30 + x) = 60 + 2x
60 + 2x + 30 + x + x = 4x + 90 = 180
4x = 90
x = 22.5
Please mark as brainliest if the answer is correct! :D

Writing? any ways if 3 miles is 1/4 of the total path then there is 3/4 remaining and we know that 1/4 is 3 miles so how many times does one fit into the denominator(4) it fits 4 times so muptily 3 by4 and you have your answer(12)
