Answer:71
Step-by-step explanation:
This can be determined by finding the x-intercept. In doing so, we let y=0 to find the value of x.
y= 2x^2 -x -3
[0 = 2x^2 -x-3]÷2
0 = x^2 -1/2 x - 3/2
Complete the squares:
1/16 + 3/2 = x^2 - 1/2x + 1/16
25/16 = (x -1/4)^2
sqrt (25/16) = x - 1/4
+/- 5/4 = x - 1/4
Thus,
x = 1/4 + 5/4 = 3/2
x = 1/4 - 5/4 = -1
Thus, the graph crosses at x = 3/2 and x = -1.
Answer:
Step-by-step explanation:
Given rectangle JKLM
As per graph, the rectangle J'K'L'M' is the transformation of JKLM
Based on one of the points we can calculate the transformation rule:
<u>Let's use points K and K'</u>
- K((-4, -8) → K'(6, -5)
- 6 - (-4) = 10
- -5 - (-8) = 3
<u>So the rule is </u>
- (x', y') → (x + 10, y +3)
<u>Trapezoid STUV:</u>
<u>Applying same rule:</u>
- T' = (6 + 10, 4 +3) = (16, 7)
