Answer:
2, 1, 1/2, 1/4
Step-by-step explanation:
2¹ = 2
2^0 = 1
2^-¹
= 1/2¹
= 1/2
2^-2
= 1/2²
= 1/2*2
= 1/4
To complete the table
2² 2¹ 2^0 2^-1 2^-2
4 2 1 1/2 1/4
Answer:
<h2>2.) When dividing by −2, he did not change the direction of the sign. </h2>
Step-by-step explanation:
-4(x + 8) ≤ -2x + 50 <em>use the distributive property: a(b + c) = ab + ac</em>
-4x - 32 ≤ -2x + 50 <em>add 2x to both sides</em>
-4x + 2x - 32 ≤ -2x + 2x + 50
-2x - 32 ≤ 50 <em>add 32 to both sides</em>
-2x - 32 + 32 ≤ +50 + 32
-2x ≤ 82 <em>divide both sides by (-2) / </em><em>flip the inequality sign</em><em>/</em>
x ≥ -41
Andrew's mistake:
2.) When dividing by −2, he did not change the direction of the sign.
Answer: An equation is *629 = n - 99. The geometry book has 728 pages*
Step-by-step explanation: The Algebra book has 99 pages LESS than the geometry book, in other words, the geometry book has 99 pages MORE than the Algebra book. This equation can be used to find the answer. I’m afraid 530 is not the answer.
Hope this helps! :)
Answer: y = 1200m + 57,600
Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.
So, we have (2,60000) and (7,66000)
y = mx + b
66000 = 7m + b
60000 = 2m + b (-)
________________________
6000 = 5m
m = 6000/5 = 1200
60000 = 2m + b
60000 = 2.1200 + b
60000 = 2400 + b
b = 60000 - 2400
b = 57600
y = mx + b
y = 1200m + 57,600
