Where is the question?
Step-by-step explanation:
(amount raised) = $2 × (number of classmates)
Answer:
y = 10
x = 25
Step-by-step explanation:
From the U theorem the sum of these two angles 120+2x+y = 180
same goes for the bottom part too:
2x-y+140 = 180 now add two equations up
120+2x+y + 2x-y+140 = 180 + 180 add like terms (-y will eliminate +y)
4x + 260 = 360 subtract 260 from both sides
4x = 100 divide both sides by 4
x = 25 since the sum of 2x-y+140 = 180 we can find the value of y by replacing x with 25
2*25 - y + 140 = 180
50 - y + 140 = 180 add like terms
190 - y = 180 subtract 190 from both sides
-y = -10 and y = 10
Answer:
range: {y | y>= -8)
Step-by-step explanation:
We have a radical here.
y = root( x + 1) - 8
y is defined as long as x+1 >= 0
so domain must be x > -1
y values would start from -8
and go upward.
range: {y | y>= -8)
