Elimination would be the best way to answer this question because you can multiply the top by 3 and the bottom by -4
Answer:
x = 4; y = 2
Step-by-step explanation:
(1) 3x + 2y = 16
(2) 2x – 2y = 4 Add (1) and (2)
5x = 20 Divide each side by 5
(3) x = 4 Substitute (3) into (2)
2×4 – 2y = 4
8 - 2y = 4 Subtract 16 from each side
-2y = -4 Divide each side by -2
y = 2
<em>Check:
</em>
(1) 3×4 + 2×2 = 16
12 + 4 = 16
16 = 16
(2) 2×4 – 2×2 = 4
8 - 4 = 4
4 = 4
=2(5x2+20x-1)
The 2 by the x has to be on top of the x
Answer:
scatter plot A: -0.90
scatter plot B: 0.89
scatter plot C: -0.76
scatter plot D: 0.55
Step-by-step explanation:
if the line is going down, it's negative and if it goes up it's positive. The closer the points are <em>the higher the number</em>.
HOPE THIS HELPS!!
The answer is 71°.
x = angle
3x = 90 - x - 14
4x - 76
x = 19°
90 - x = 71°
