8+ the product of 2 and a number to the third power, what it means 2×m cubed. So it is 8+2m (cubed)
hope it helps
Answer:
(-3,-10)
Step-by-step explanation:
Given part a, you seem to know the midpoint formula. We can easily edit that to figure out what an endpoint is. Say that a variable "a" represents the x coordinate of D, and b the y coordinate. As the x coordinate of M is 0.5, and the x coordinate of C is 2, we can use the midpoint formula to say that
. Multiplying both side by 2, we get that a+2=-1, and subtracting both sides by 2, a=-3. Similarly,
, b+7=-3, and b=-10, making our answer (-3, -10). Let me know if you have any questions.
Answer:
y = 2
Step-by-step explanation:
Addition Method:
4x - 2y = 6
2x + y = 7
-2(2x + y) = -2(7)
4x - 2y = 6
-4x - 2y = -14
-4y = -8
y = 2
Substitution Method:
4x - 2y = 6
2x + y = 7
-2y = 6 - 4x
2y = 4x - 6
y = 2x - 3
2x + (2x - 3) = 7
4x - 3 = 7
4x = 10
x = 2.5
2(2.5) + y = 7
5 + y = 7
y = 2

Answer:
14 weeks.
Step-by-step explanation:
15x-10=200
add 10 to both sides
15x= 210
divide by 15
x=14 .
