Answer:
x = 27
Step-by-step explanation:
2/3x -2= 16
+2 +2
---------------------
2/3x = 18
multiply by 3 on both sides
2x = 54
divide by two on both sides
x= 27
Answer:
y = 54
Step-by-step explanation:
We know the sum of the angles of a triangle are 180
72+y+y = 180
Combine like terms
72 + 2y = 180
Subtract 72 from each side
72-72 +2y = 180-72
2y = 108
Divide each side by 2
2y/2 = 108/2
y = 54
For this question it is the difference of two perfect squares. This means your final answer will be (2x - 5)(2x + 5). This answer is not listed so it would be none of the above.
After review, B technically works because it is the difference of two perfect squares. This allows you to take the square root of each term while ignoring the sign and then place that back in with the original sign.
Answer:
y = 
+3
Step-by-step explanation:
PART A)
The rate of change is -40 songs each week, because the amount of songs left to be downloaded decrease by 40 every week.
<span>the initial value is 200 at 0
weeks, which means that there are 200 songs to be downloaded at the
beginning</span>
PART B)
<span><span><span>
<span><span>calculate the slope:
</span><span>
m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use the line equation in form of point-slope
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200</span></span>
