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
The commutative property says that a+b=b+a. Basically the sum is the same no matter the order in which you add the terms.
Final answer: 9+3=12
Answer:
- domain: [0, 7]
- range: [-2, 4]
- is a function? YES
Step-by-step explanation:
The domain is the horizontal extent, which is from x=0 to x=7.
The range is the vertical extent, which is from y=-2 to y=4.
The curve passes the vertical line test, so the relation IS A FUNCTION.
_____
The vertical line test asks whether any vertical line intersects the curve at more than one point. If so, the relation is NOT a function.
This is an inverse function, so first we have to flip x and y:
y = 2x - 6
x = 2y - 6
Now, let’s substitute 2 into the equation:
2 = 2y - 6
Solve:
8 = 2y
y = 4
Hope this helped!
Answer:
16 team members.
Step-by-step explanation:
To find 80% of 20, multiply 20 by 0.8.
20 × 0.8 = 16.
