Answer:
Step-by-step explanation:
Equation 1:
Equation 2:
Subtract 3b from both sides in Equation 1:
Divide both sides by 2:
Substitute this into Equation 2:
Add 2 to both sides:
Divide both sides by -4:
We know that . Plug in b = -7 value:
25 times 18 times 6 would be best
Answer: r= -1000
Step-by-step explanation:
Solve for r by simplifying both sides of the equation, then isolating the variable
Answer:
The inverse f-1(x) = (2 - x)/4 + 1.
Step-by-step explanation:
Let y = -4 /(x - 1) + 2
-4/(x - 1) = y - 2
x - 1 = (y - 2) / -4
x = -(y - 2)/4 + 1
x = (2 - y)/ 4 + 1
Now replace x by f-1(x) ( the inverse) and y by x:
f-1(x) = (2 - x)/4 + 1.
Let be the measure of the angle in question. Its complement has measure . We're told that this angle is congruent to 1/3 of its complement, so that
