Answer:
she should use a scale 8)
Step-by-step explanation:
x = 3
Step-by-step explanation:
First we would simplify the left hand side of the equation by expanding the brackets
so 2(4-3x) = 8-6x and
5(2x-3) = 10x-15
This gives the left hand side as 8-6x+10x-15. So the overall equation becomes
8-6x+10x-15 = 20-5x.
Grouping the unknown values on one side and integers on one side of the equation gives us
8-15-20=6x-10x-5x (note the sign changes when numbers and unknown values are moved to the other side of the = sign
Solving further, -27 = -9x i.e x = -27/-9 = 3
Hence x = 3
Answer:
The angle is 28.
Step-by-step explanation:
If we consider the system below (were "A"is the angle):
A + [(x/2)-14] = 90 (complement)
A + x = 180 (suplement)
We can isolate "X=180 - A" and apply this in the first equation. This way we are able to have only one variable, and w'll see that A=28.
The first thing you would do is switch the x and y (B).
For example, to find the inverse of y = 2x + 8:
1. Swap x and y
x = 2y + 8
2. Solve for y (set the equation equal to it):
x - 8 = 2y
y = (x - 8) ÷ 2
= 1/2x - 4
Answer:
All the lines except the black one will exceed the yellow line as x approaches infinity.
Step-by-step explanation:
The yellow line grows at a linear fashion, assuming that it'll stay that way the only line that won't exceed it is the black line, since it also grows linearly, but with a slower rate, therefore it'll never surpass the yellow line. All the other lines have a growing rate of change, therefore they'll all eventually pass the yellow line.
