Answer:
y=-1/2x+3/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(5-1)
m=-2/4
m=-1/2
y-y1=m(x-x1)
y-1=-1/2(x-1)
y=-1/2x+1/2+1
y=-1/2x+1/2+2/2
y=-1/2x+3/2
6r+70=-2(35+3r)
multiply the bracket by -2
(-2)(35)=-70
(-2)(3r)=-6r
6r+70=-70-6r
move -70 to the left side
sign changes from -70 to +70
6r+70-70=-70-70-6r
6r=-70-70-6r
move-6r to the left side
6r=-140-6r
move -6r to the other side
6r+6r=-140-6r+6r
12r=-140
divide both sides by 12
12r/12=-140/12
r=-140/12
reduce- by dividing by 4
-140/4=-35
12/4=3
Answer:
r= -35/3 and r=-11 2/3
B ,, because 12÷4 is 3,, and each 4th is 3,, which here misna only used 1/4
Let's call the number "n"
if we write in an equation what you said it's like this:
n*2+4-n-3=n+1.
first i will move all the "n"s to the left and all the numbers to the right
n*2-n-n=1+3-4
which is....
0=0
this means that for EVERY number, if you double it, add four, subtract three, you will get this number plus one. <span />
