Answer:
What is the expression? All I see are the answers.
Step-by-step explanation:
The selling price of 18 shirts is given by g(f(18))
g(f(x))= 5.f(x) + 6= 5[(5/6)x+5]+6=(25/6)x+25+6
g(f(x))=25/6)x+25+6
g(f(18))=25/6).18+25+6=106
the answer is 106

Step-by-step explanation:
The vertex of the parabola is (1, 2), focus of the parabola is (-2, 2), and directrix x = 4.
<h3>What is a parabola?</h3>
It is defined as the graph of a quadratic function that has something bowl-shaped.
We have a parabola equation:
The standard form of the parabola:
(h, k) is the vertex of the parabola and (f, k) is the focus.
h = 1, k =2, and f = -2
The directrix is x = 4
Thus, the vertex of the parabola is (1, 2), focus (-2, 2), and directrix x = 4.

Answer:
Two buses leave towns 760 mi apart at the same time and travel toward each other. One bus travels
18 mi/h slower than the other. If they meet in
5 hours, what is the rate of each bus?
~~~~~~~~~~~~~~~~
Let x be the rate of the slower bus, in miles per hour.
Then the rate of the faster bus is (x+18) mph, according to the condition.
The slower bus covered 5x miles before the buses meet each other.
The faster bus covered 5*(x+18) miles before they meet each other.
The sum of distances covered by buses is 3x + 5*(x+18).
It is equal exactly 760 miles. It gives you an equation
5x + 5(x+18) = 760.
Simplify and solve for x:
5x + 5x + 90 = 760,
10x = 760 - 90,
10x = 670 ====> x = 670%2F10 = 67.
Thus you found the rate of the slower bus. It is 67 miles per hour.
Then the rate of the faster bus is 67 + 18 = 85 mph.
Solved.
