Answer:
I think so.
Step-by-step explanation:
If you do the math 2(5-3) exponent 2 - 4 = 4
So if y is 4 you should be correct!
Thb I think you need to know the value of y to solve this question.
Answer: Ratio of Parts
<u>Step-by-step explanation:</u>
The ratios are equal so the triangles are similar.
Answer: m=-1
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
m-(-(4+m)+2)=0
1.1 Pull out like factors :
2m + 2 = 2 • (m + 1)
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
2.2 Solve : m+1 = 0
Subtract 1 from both sides of the equation :
m = -1
Answer:
B. stratified.
Step-by-step explanation:
If a population is composed by identifiable groups or strata, with large variations between groups, the stratified sampling should be applied in order to comprehend and represent all of the different groups in the sampling process.
Therefore, the answer is alternative B. stratified.
Answer:
C = 50p +900
Step-by-step explanation:
Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).
Equation: C = 900 +50p
__
The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.
