I hope the chart above makes sense. If not, plot the points as follows:
- for the top section, (-2, -4), (-3, -4), (-4, -4) ... draw an arrow to -∞
- for the middle section, (-2, -4), (0, 0), (2, 4) then connect them
- for the bottom section, (2, 4), (3, 4), (4, 4) ... draw an arrow to ∞
Answer:
x = -5 or x= 2
Step-by-step explanation:
|-4x-6| = 14
There are two solutions, one positive and one negative
-4x-6 = 14 -4x-6 = -14
Add 6 to each side
-4x-6+6 = 14+6 -4x-6+6 = -14+6
-4x = 20 -4x = -8
Divide by -4
-4x/-4 = 20/-4 -4x/-4 = -8/-4
x = -5 x = 2
Answer:
The coordinate of the midpoint is -2 1/2.
Step-by-step explanation:
Think of "midpoint" as "average" in this problem. The average of the endpoints -10 and 5 is (-10 + 5)/2, or -5/2, or -2 1/2
Assuming the numbers after 10 are exponents:
1 million is equal to 10^6. Let's multiply this by the original expression.
8.7*10^4*10^6
Add exponents when multiplying with the same base
10^4*10^6= 10^10
Final answer: 8.7*10^10, or D
