Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
Answer:
no solutions
Step-by-step explanation:
b-9-b=-18
Combine like terms
0b -9 = -18
-9 = -18
This is never true so there are no solutions
Answer:
C
Step-by-step explanation:
we know that
In a right triangle
The cosine of an angle x is equal to
cos(x)=\frac{adjacent\ side\ angle\ x}{hypotenuse}
The sine of an angle x is equal to
sine(x)=\frac{opposite\ side\ angle\ x}{hypotenuse}
The tangent of an angle x is equal to
tan(x)=\frac{opposite\ side\ angle\ x}{adjacent\ side\ angle\ x}
therefore
the answer is the option C
Answer:
21
Step-by-step explanation:
Midpoint means the middle, so all you have to do is divide 42 by 2 :)
