Answer:
The answer is 0
Step-by-step explanation:
m(x)=2x3- 3x+12
m(-2)=6-3(-2)+12
=6-6
=0
Square root of 89 because 8^2+5^2 is 89 and it isn’t a perfect square
You need to get the denominator at the same number first. The Lowest common denominator is 6. So multiple 7/3 by 2 and 5/2 by 3 to get 14/6 and 15/6. 15/6 is greater. 15/6 is 5/2, so the answer is 5/2. I hope this helps!
Answer:
r = 2.5
Step-by-step explanation:
x is directly proportional to y. This can be written as,
x ∝ y
In terms of constant, the proportionality can be written as,
x = ry
Where r is the constant. The table has a set of values for x and y. Let's substitute the values in the first row into the equation with the constant.
10 = r × 4
r =
r = 2.5
Lets check with the second row.
12.5 = r × 5
r =
r = 2.5
Since both sets of values have the same answer for the constant, this means that the third row of values should probably have the same constant.
r = 2.5
