Answer:
smaller angle is 50.5 degrees
Step-by-step explanation:
supplementary angles when added together = 180 degrees
(2x + 10) + 6x + 8 = 180
combine like terms
8x + 18 = 180
move the 18 over by subtraction
8x = 162
divide by 8 to get x by itself
x = 20.25
so plug in to find smaller angle
2(20.25) + 10 = 50.5
6(20.25) + 8 = 129.5
The values of x and y that satisfy this system of equations are 10 and 5 respectively
<h3>Simultaneous equation</h3>
Given the system of equations
x + y = 20
3x - 3y = 30
_____________________
x + y = 20
x - y = 10
Add the equations
2x = 20 + 10
2x = 30
x = 30/2
x = 15
Substitute
x -y = 10
15 - y = 10
y = 5
Hence the values of x and y that satisfy this system of equations are 10 and 5 respectively

Answer:
I am sorry. To answer a test is against the Honor Code, I cannot help you.
Step-by-step explanation:
Remember PEMDAS :)
F(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11
f(x) = x < 1
f(-2) = -2 < 1
f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0
f(x) = x > 1
f(-2) = -2 > 1
f(-2) = -2 < 1
