Answer:
D
Step-by-step explanation:
to show the general direction of the graph, we should find the end points and one in the middle, lets see what happens why x is -4, 0, and 4. when x=-4, it is 16*-3/4 (which is negetive), when x is 0, y is 0, and when x is 4, the same this happens in the first number. If these points are plotted, it is shown as a parabola pointing downwards. The max is will be is 0. because before 0, the numbers are negetive in the y axis, and after they are negetive in the y axis, and it tops out at y=0 when x=0. Therefore Y is smaller than or equal to 0, or D.
Company a = 22 + 0.07m
company b = 8 + 0.12m
We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b
company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280
Therefore, the two companies will cost the same if you talk for 280 minutes
When using technology,the first step in copying a line segment is to <span>Create a point anywhere on the circle. The answer is letter D.</span>
<span>So we want to know which of theese products are negative. We have three rules: -1*(+1)=-1 and -1*(-1)=+1 and +1*(+1)=+1 Lets calculate and check: A. is negative, B. is negative, C. is positive and D.positive. So Aand B are negative and that is the correct answer.</span>
Answer:
Wrong problems = 32
Step-by-step explanation:
Total no of problems = 200
Charlotte earned a grade of 84% on her multiple-choice.
Correct problems,
Wrong problems = 200 - correct problems
= 200 - 168
= 32
Hence, there are 32 problems on the final exam Charlotte get wrong.
