Your question answers itself. You solve by graphing.
I like to subtract one side of the equation from the other, so the solutions are where the graph crosses the x-axis (the resulting function value is zero).
It can be useful to find the "turning point" of each absolute value expression (where its value is zero) and graph that and some points on either side.
Answer:
57.50+4x=75.10
x=4.4
So she can use up to 4.4 gigabytes of data
Answer:
2m
Step-by-step explanation:
2 * 1.5 = 3, the total height
we know that there are three metres total and 1 is half the other, so we divide 3m by 3 = 1m, the height of B,
as A = 2B, A = 2m
1. Rotation by 180° (clockwise or anti-clockwise) about the origin has a rule:
(x,y)→(-x,-y).
Then
(-4,-10)→(4,10).
2. Translation 1 unit to the right has a rule:
(x,y)→(x+1,y).
Then
(4,10)→(5,10).
3. After rotation and translation the image of point (-4,-10) is point (5,10).
Answer: (5,10).
14-21= -7
-7 is your answer ^^
