Answer: 49</h3>
Work Shown:
Replace x with 3, replace y with -8. Use order of operations PEMDAS to simplify.
x^2 + y^2 + x*y
3^2 + (-8)^2 + 3*(-8)
9 + 64 - 24
73 - 24

Answer: 41,224
Step-by-step explanation:
Answer:
8/30
Step-by-step explanation:
Dividing fractions is almost the same as multiplying to do it you just have to flip the second fraction and change the division sign to a multiplication sign like this,
2/10×4/3
then from there, you have to multiply the top numbers and the bottom numbers
2×4=8
10×3=30
then put them together
8/30
Answer:
6 degrees
Step-by-step explanation:
-3 + 9 is 6. To check this answer you can subtract 9 from 6
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2
Hope that helps!
