"Vary directly" is another way of saying "directly proportional".
In simple English, this just means, as one increases, the other increases too.
a = 6
b = 4
The question says find out what a is when b is 16.
First, lets find how many times larger b has gotten.
16/4 = 4
b had gotten 4 times bigger to go from b=4 to b=16
If a is varying directly, it means that it will also get 4 times bigger.
Therefore, a = 6 x 4 = 24
Answer:
The slope would be C) -1/2
Step-by-step explanation:
To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -4)/(0 - 2)
m = 1/-2
m = -1/2
Answer:
3+(-4)= -1
-3+(-4)= -7

Answer:
The answer is 13 7/8
Step-by-step explanation:
First, you must add 2 to 11 3/8, which gives you 13 3/8. Then you change 1/2 to 4/8. Add 4/8 to 13 3/8 equals 13 7/8.
