Answer:
3x^2 -7x +2
Step-by-step explanation:
(15x^2 -35x+10) ÷5
(15/5x^2 -35/5x+10/5)
3x^2 -7x +2
This will factor
(3x-1) (x-2)
Answer:
1/2 IN FRACTION FORM
0.5 IN DECIMAL FORM
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
Let x equal each of the values on the table, and find the value of the function for that value of x.
f(x) = 5x - 5
x = -4
f(-4) = 5(-4) - 5
f(-4) = -20 - 5
f(-4) = -25
x = 0
f(0) = 5(0) - 5
f(0) = 0 - 5
f(0) = -5
x = 1
f(1) = 5(1) - 5
f(1) = 5 - 5
f(1) = 0
x = 3
f(3) = 5(3) - 5
f(3) = 15 - 5
f(3) = 10
x = 5
f(5) = 5(5) - 5
f(5) = 25 - 5
f(5) = 20
x f(x)
-4 -25
0 5
1 0
3 10
5 20
Answers:
- Vertical change = 1
- Horizontal change = 2
- Rate of change = 0.5
====================================================
Explanation:
Imagine that we have point A as a buoy in the water. So the horizontal line through 1 on the y axis is the water line. How much should the water line go up so that points A and B are on the same horizontal level? That would be 1 unit up. This is the vertical change. Another term for this is "rise".
After the water goes up, and A and B are on the same level, the question is now: how far to the right do we go from A to B? That would be 2 units. This is the horizontal change. Another term for this is "run".
Using those two values, we can compute the rate of change aka slope.
slope = rise/run = 1/2 = 0.5
So each time we go up 1 (rise) we move to the right 2 (run).
The slope is positive since we're moving uphill while moving to the right.
Answer: 80 g
Step-by-step explanation:
Given
The frosting is made of cream cheese and Powdered sugar in the ratio of 3:2.
If 120 g of cheese is used
Assume the quantity of powdered sugar is x
So, we can write the ratio as
So, 80 g of powdered sugar is used.
