Answer:

33k - 15

Step-by-step explanation:

Given expression,

\qquad{8k-5(-5k+3)}

By the distributive property,

=8k-5(-5k) - 5(3)

=8k+25k-15

By combining like terms,

=33k-15

∵ Further simplification is not possible,

Hence, the required simplified form of the given expression is,

NEED HELP ASAP<br><br> Question A.) k=5<br> Question B.) ????
andrezito [222]

Answer:

b) f^{-1}(x) = \frac{4x+5}{3}

Step-by-step explanation:

b) To find the inverse function, switch the x and y variables and solve for y:

f(x) = \frac{3x-5}{4}\\y = \frac{3x-5}{4}\\x = \frac{3y-5}{4}\\4x = 3y-5\\4x+5 = 3y\\\frac{4x+5}{3} = y\\f^{-1}(x) = \frac{4x+5}{3}

Verify Answer:

f(1) = \frac{3(1)-5}{4} = -0.5\\f^{-1}(-0.5) = \frac{4(-0.5)+5}{3} = 1
