Step-by-step explanation:
the square root is basically exponents 6*6 is 6^2 which is 36.
Answer:
f(-3)=3
Step-by-step explanation:
Plug in -3 for x.
f(-3)=-4(-3)-8
f(-3)=12-8
f(-3)=3

Answer:
See below for answer.
Step-by-step explanation:
RP/RT =RQ/RS Given
∠R = ∠R
ΔPQR similar to Δ TSR If the measures of two sides of a triangle are proportional to the measures of two corresponding sides of another triangle and their included angles are congruent, then the triangles are similar.
Answer:
(- 3, 2 )
Step-by-step explanation:
To determine which ordered pair is a solution, substitute the x and y- coordinates of the given points into the left side of the equation.
If the result is equal to the right side then the pair is a solution.
(2, - 2)
- 6(2) - 7(- 2) = - 12 + 14 = 2 ≠ 4 ← not a solution
(- 2, 2 )
- 6(- 2) - 7(2) = 12 - 14 = - 2 ≠ 4 ← not a solution
(- 3, 2 )
- 6(- 3) - 7(2) = 18 - 14 = 4 = right side ← a solution
(2, - 3 )
- 6(2) - 7(- 3) = - 12 + 21 = 9 ≠ 4 ← not a solution
(- 3,2 ) is a solution of the equation
Answer:
Pipe 1 twice as fast as pipe 2.
(Pipe 1 time * Pipe 2 time) / (Pipe 1 time + Pipe 2 time) = combined time
(x * (x/2)) / (x + x/2) = 10
(x^2/2) / 1.5 x = 10
x^2 / 2 = 15 x
x^2 /2 - 15 x = 0
x = 30 (slow pipe)
x/2 = 15 (fast pipe)
So it would take 30 hours using the slow pipe only.
