Answer:
B: (2, -1)
Step-by-step explanation:
1) First isolate the y in both equations
2) Set the equations equal to each other
3) Solve for x (you should get 2 and 5)
4) Insert the x values back in to get your y values
5) You should have gotten (2, -1) and (5, 2)
These are your two answers, but the question is only asking for one solution and (5,2) isn't one of the options, so it has to be (2,-1).
Cube has 4 lateral faces
4s² = 676 = 4 × 169
s² = 169
s = 13
your answer is 13

Answer: Her weekly allowance is 24 dollars
Step-by-step explanation:
If she is left with $12 spending half of her weekly allowance the we could set up the equation.
1/2 of x = 12 where x is her weekly allowance.
1/2x = 12
x = 24
Answer:
d = -19
Step-by-step explanation:
64 = -3d + 7
Subtracting 7 on both sides,
64-7 = -3d
57 = -3d
Divide both sides by -3,
d = -19
