Step-by-step explanation:
-4x + 9y = -22
-9x -9y = 126
-13x = 104
x = -8
8 +`y = 14
y = 6
(-8,6)
Answer:
A = 60°
Step-by-step explanation:
First to find the missing angle you add the three known angles,
90 + 135 + 75 = 300
Then, you subtract, 360 - 300 = 60
<h3>So, 360° = 60° + 90° + 135° + 75°</h3><h3 />
Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.
No, he needs to do 5(to the power of 2) plus 3(to the power of 2)
this should give him 25 plus 9 = 34
The answer isn't A or B because those two are not factored. D is wrong because 8•8=64 not 16. So that leaves us with C (4•4=16).
