13.80 x 2= 27.60
1 pizza equals 13.80 so two pizzas will be twice that money amount. Both pizzas will cost $27.60.
I hope this helped
Answer:
the y-intercept is -1, or (0, -1)
Step-by-step explanation:
Identify the coordinates of the point where the line crosses the y-axis. They are (0, -1), and so the y-intercept is -1, or (0, -1).
f(x) = sqrt [( x - 3) / (x - 5)]
well x cannot be 5 because that would make x - 5 = 0.
Also the fraction x - 3 / x - 5 cannot be negative because theres no real square root of a negative.
So x must be <= 3 or > 5
In interval notation the domain is ( -∞,3] or (5 , ∞)
Since this is a quadrilateral, all angles together = 360°. The angle that is 128° is congruent to angle y, so y=128°. Angle x and y are supplementary, meaning together they equal 180°, or x+y=180°. So x=180°-y. Which means, x=180°-128°=52°.
