The measures of two supplementary angles are (2x + 10)° and (6x + 8)°.
bearhunter [10]

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

Amelie solves the following system of equations.
PIT_PIT [208]

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

Find f(-2) for the function:<br><br> f(x)= 3x^2-1, x&lt;1<br> x+2, x&gt; 1
azamat
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
