Answer:
f(3) = -2
Step-by-step explanation:
Given the f(x) = -2x² + 3x + 7, to find f(3):
We can substitute 3 as the value of x in the given function:
f(x) = -2x² + 3x + 7
f(3) = -2(3)² + 3(3) + 7
f(3) = -2(9) + 9 + 7
f(3) = -18 + 9 + 7
f(3) = -9 + 7
f(3) = -2
Therefore, f(3) = - 2.

Your answer is B, (1,5)
Based on your equation, 5x means in one movement of the x axis it increases 5 spaces on the Y axis. Since there is nothing after the 5x indicating it is starting elsewhere this means it starts at 0.0. So after the first movement on the x axis your value will be 1 plug in your x axis value to the equation f(x)=5x so it will look like f(1)=5•1 and then you will have both values needed to form your answer (1,5)
Since it is shown that 2 of the sides of the triangle are congruent, we can assume that they have the same angle measures.
so to solve for the missing angle you can set up an equation equal to 180 since all triangles add up to 180 degrees.
21 + 21 + x = 180
42 + x = 180
x = 138
the value of the missing angle should be 138 degrees

No, it isn't!
first, the discount is 20 percent of 18 dollars, that is 18/5=3.6
this means that during the first week the prize is 18-3.6=14.4
now, the prize is marked up 20 % of 14.4! this is 2.88
so the prize later will be 14.4+2.88, that is 17.28, not 18
what is relevant here is what a number is a percent OF
