Answer:
M=(2,1)
Step-by-step explanation:
The mid points is half the distance of the x and y values so
-4 and 8 are 12 apart so 12/2=6 so -4+6=2
so the x value of M is 2
same for the y value 6 and -4 are 10 apart 10/2=5 and 6-5=1 so
so the y value of M is 1 so
M=(2,1)
Answer:
-2k+6
Step-by-step explanation:
-2k-(-5)+1
multiply negative to negative 5 and get a positive
-2k+5+1=
-2k+6 or 6-2k
Answer:
16
Step-by-step explanation:
6+8+10+20=44+16= 60 divided by 5 is 12
Answer:
b= y-intercept m=slope x=variable.
Step-by-step explanation:
x= y/m-b/m
m=y/x-b/x
b=y-mx
Answer:
<h2>15</h2>
Step-by-step explanation:
∠6 and ∠7 are Alternate Interior Angles.
The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.
m∠6 = m∠7 → 4x - 15 = x + 30 <em>add 15 to both sides</em>
4x = x + 45 <em>subract x from both sides</em>
3x = 45 <em>divide both sides by 3</em>
x = 15
