Answer:
Yes
Step-by-step explanation:
Tan = sin / cos
If sin is negative, ans cos is negative, then tangent is positive.
Tan= (-)/(-) = (+)
Let's do an equation. 5(x+6)=9x-2. Now distribute into parentheses. 5x + 30=9x-2. Now -5x on both sides. New equation is 4x-2=30. Add 2 on both sides. 4x=28. Now divide by 4. X=8. Your number is 8
C because the highest and lowest Y values are at -7 and 4.
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:

Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12
