Answer:
8
Step-by-step explanation:
Total meaning addition, you would use the opposite operation to find the answer.
28 - 20 = 8
And to check your work you would add;
20 + 8 = 28
which is the brothers total combined age.
Step-by-step explanation:
first one is 6:9
second is 20:40

Answer:
y-6 = -2(x+1)
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-2-6)/(3--1)
= (-2-6)/(3+1)
= -8/4
= -2
Then we can point slope form where
y -y1 = m(x-x1)
where m is the slope and x1,y1 is a point
y-6 = -2(x--1)
y-6 = -2(x+1)
Answer:-19=33y
Step-by-step explanation:
-5-15y-1=14y-32y
-19-15y=18y
18y+15y
-19=33y
Answer:
Y = 6*y
Step-by-step explanation:
We have Y = b * y by a factor of 6.
That is, b = 6.
now, to find what results only in a horizontal compression of y = b * y by a factor of 6.
By transformation rule, the function would be a horizontal compression f (a * x) if a> 1.
Therefore, knowing the above, the answer would be:
Y = 6 * y
