Answer: A) and B)
Step-by-step explanation:
So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.
The second one you find the distance it moves each second.
You do this by distance over time d/t. Then you divide the 408 by that number.
So 264cm / 11 seconds = 24 cm/sec
Then 408cm/ 24cm per sec = 17s
Answer:
32
Step-by-step explanation:
subract the amount he needs by the number he has
Answer:
x ⥶ -3
Step-by-step explanation:
2x - 7 -3x ⥶ 10
-x + 7 ⥶ 10
-x ⥶10 - 7
-x ⥶ 3
Answer:
x= 2y - 3/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Problem 44
The term "bisect" means "cut in half".
Since BD bisects angle ABC, this means the smaller angles ABD and DBC are congruent.
angle ABD = angle DBC
x+15 = 4x-45
15+45 = 4x-x
60 = 3x
3x = 60
x = 60/3
x = 20
<h3>Answer: x = 20</h3>
========================================================
Problem 45
We use the same idea as the previous problem
angle ABD = angle DBC
2x+35 = 5x-22
35+22 = 5x-2x
57 = 3x
3x = 57
x = 57/3
x = 19
<h3>Answer: x = 19</h3>
