Answer: a ≤ 4 or (-∞, 4]
Step-by-step explanation:
Here we have the inequality:
4a ≤ 16
this means that the left sides is less or equal than the right side.
First, find the equal part:
4*a = 16
a = 16/4 = 4
So the maximum possible value of a is 4.
Now, all the values of a smaller than 4 also make the inequality true (even the negative values) so the possible values of a are:
a ≤ 4 or (-∞, 4]
We meet again
so first divide 60 by 5
this gives 12
then multiply 12 by 4
giving a final answer of 48
Answer:
t = 9
Step-by-step explanation:
Here, we want to find the value of t
2(t-3)^2 -72 = 0
2(t-3)^2 = 72
divide both sides by 2
(t-3)^2 = 72/2
(t-3)^2 = 36
(t-3)^2 = 6^2
Since powers are equal, we equate base
t-3 = 6
t = 6 + 3
t = 9
Answer:
domain: -2, -1, 0, 1, 2
range: 0, 2, -4, -8
Step-by-step explanation:
domain is the possible x values of the function. in this case, its a collection of plotted points, so we can just line up the x values of these points.
range is the possible y values of the function. again, we can just look at the y values of the points, line them up, and select our answer.
Answer:
4.9
Step-by-step explanation:
we can use tangent
tan = opposite / Adjacent
opposite = tan * adjacent
opposite = 4.9
