2x - 3 [5x - 2(6-x)] =
2x - 3 [ 5x - 12 + 2x ] =
2x - 3 [ 7x - 12 ] =
2x - 21x + 36 =
-19x + 36
Answer:
The value of y is 3.
Step-by-step explanation:
Given points: P(12,-2), Q(5,-10), R(-4,10) and S(4,y).
We need to find the value of y so that line PQ is perpendicular to line RS.
Slope formula:
Slope of PQ is
Slope of RS is
The product of slopes of two perpendicular lines is -1.
Add 10 on both sides.
Therefore, the value of y is 3.
Answer:
Step-by-step explanation:
<u>Multiply the number of containers by the amount in each to find the total amount of sugar:</u>
- 2 4/5 * 2 3/7 =
- 14/5 * 17/7 =
- 2*17/5 =
- 34/5 =
- 6 4/5
This is the answer to the problem. You basically substitute the -6 in for the f(x)
