Answer:
Uhm anything that includes minus, times, divide, subtract, and equal would be a equation
Step-by-step explanation:
X = 1
3( x - 2 ) + 2 ( x + 5 ) = 9 x
5x+4=9x
x=\frac{-4}{-4}
x=1
1) The domain is all the possible x values in the function so it would be [-4,4]
2) There are only 3 zeros shown on the graph and they are (-2, 0) (0, 0) (2, 0) the zeros are the value of x when y = 0.
3)The function is positive/Negative is asking for what x values make the y values positive aka interval notation. The function is positive if x = (0, 2) because 0 and 2 aren't included you use parentheses () instead of brackets []
The function is negative if x [-4, -2), (-2,0), (2,4]
Note that m∠4 and m∠1 are vertical angles, and so they would have the same measurements (same for m∠3 & m∠2). Note that m∠1 and m∠2 are supplementary angles (going to have a total measurement of 180°)
m∠2 = 50° (given)
m∠1 + m∠2 = 180
m∠1 + 50 = 180
Isolate m∠1. Note the equal sign. What you do to one side you do to the other. Subtract 50 from both sides
m∠1 + 50 (-50) = 180 (-50)
m∠1 = 180 - 50
m∠1 = 130°
m∠1 = 130° is your answer
hope this helps
