Answer:
(-2,3)
Step-by-step explanation:
You can see that the purple is the new triangle. So look at the coordinate of the D. You can see that it is plotted at (-2, 3)
Answer:
b
Step-by-step explanation:
to determine which point is a solution, substitute the x-coordinate of the point into the equation and if the value is equal to the y-coordinate of the point then it is a solution.
(a) (- 1, 3)
y = (- 2 × - 1) + 4 = 2 + 4 = 6 ≠ 3 ⇒(-1, 3) is not a solution
(b) (- 2, 8)
y = (- 2 × - 2) + 4 = 4 + 4 = 8 ⇒ (- 2, 8) is a solution
(c) (0, 1)
y = 0 + 4 = 4 ≠ 1 ⇒ (0, 1) is not a solution
(d) (4, 2)
y = (2 × 4) + 4 = 8 + 4 = 12 ≠ 2 ⇒ (4, 2) is not a solution
Answer:
the greatest common factor is 2
Step-by-step explanation:
none of the other numbers listed can go into 10, 14, and 16.
Answer:
x = 8
Step-by-step explanation:
Chords AB and BD form an inscribed angle so <ABD = 5x
also given mAD = 80
Since inscribed angles are half the measure of their intercepted arc, angle <ABD is equal to 1/2(80 degrees), which is 40 degrees.
Now you have:
<ABD = 40
5x = 40
x = 8
Answer
x = 8
Class 2 scored better on average
<h3>How to determine which class scored better on average?</h3>
The averages and the standard deviations are given as:
Class 1
Mean score = 7.8
Standard deviation = 1
Class 2
Mean score = 8.1
Standard deviation = 0.2
As a general rule, the smaller the standard deviation; the better the average
Class 2 has a smaller deviation
Hence, class 2 scored better on average
