A plane has two dimensions and extends infinitely in both dimensions.
Enrollment at X = 0 is at 20.
Enrollment at X = 8 is 120.
Find the difference between those values:
120 - 20 = 100
Divide that difference by the difference in the x values:
100 /8 = 12.5
The answer is D. 12.5
Answer:
don't understand
but mean = <u>summation x</u>
total number
15=<u>7+4+5+2x+11</u>
5
15=<u>27+2x</u>
5
multiply both sides by 5
15×5=<u>2</u><u>6</u><u>+</u><u>2</u><u>x</u> ×5
5
75=26+2x
75-26=2x
<u>49</u>=<u>2x</u>
2. 2
x= 24.5
Answer: -6b - 12 + 8
Step-by-step explanation: To simplify/find an equivalent expression to -6(b + 2) + 8, we just need to get rid of the parentheses. This can be done by multplying -6 by everything insde the parentheses.
-6 × b = -6b
-6 × 2 = -12
Now, we add our answers together. Don't forget to add the 8 to the end!
-6b + -12 + 8
-6b - 12 + 8

= 
The 2 right triangles are similar and so the ratios of corresponding sides are equal
The corresponding sides are x and 2, 6 and 1.5, hence
=
