Step-by-step explanation:
<u>Step 1: Define</u>
(6c - 1)(7c + 3)
<u>Step 2: Expand</u>
- Expand [FOIL]: 42c² + 18c - 7c - 3
- Combine like terms: 42c² + 11c - 3
Answer: -2
=====================================================
Draw a vertical line through 4 on the x axis. This vertical line crosses the parabola at some point (which we'll call point A). Draw a horizontal line from point A to the y axis and note how it lands on y = 12. Therefore the point (4,12) is on this parabola.
Repeat the same steps as before to find that (8,4) is also on the parabola
We need to find the slope of the line through (4,12) and (8,4)
m = (y2 - y1)/(x2 - x1)
m = (4-12)/(8 - 4)
m = -8/4
m = -2
The slope of this line is -2 meaning that the average rate of change from x = 4 to x = 8 is -2.
The line goes down 2 units each time you move to the right 1 unit.
Answer:
Square
x = 2
y = 1
Step-by-step explanation:
- All sides of the given quadrilateral are marked with identical signs so all sides are equal.
- Also, each angle is right angle.
- So it is a square.
Measures of all ll sides of a square are equal.
Therefore,
5x - 4 = 3x
5x - 3x = 4
2x = 4
x = 4/2
x = 2
5y + 1 = 2y + 4
5y - 2y = 4 - 1
3y = 3
y = 3/3
y = 1
Answer:
The correct option is A.
Step-by-step explanation:
The correct option is A.
If u notice the second transformation it would shift triangle ABC 3 units to the left and reflect it across x = 4 so this will not map ABC into DEF.
If u notice first transformation it will shift triangle ABC 7 units down and reflect it across x=4 so this will map ABC into DEF.
Thus option A is correct....
