Answer: -15

Step-by-step explanation:

You do what is in parentheses which comes out to be -3

So -24+ (-3) to the second power

Then do the exponent which comes out to be 9

So now we have -24+9

Solve this then we have our answer of -15

Graph both functions to find the solution(s) to the system. Use the line tool to graph the line.

kumpel [21]

The graph shows solutions to be ...
(x, f(x)) = (x, g(x)) = (-2, 5), (2, -3)

_____
Analytically, it works well to find
g(x) -f(x) = 0
(x^2 -2x -3) -(-2x +1) = 0
x^2 -4 = 0
x^2 = 4
x = ±√4 = ±2
Then
f(-2) = -2(-2) +1 = 5
f(2) = -2(2) +1 = -3

Which figure could be the result of dilating the trapezoid with a scale factor between 0 and 1? On a coordinate plane, a trapezo

Lelechka [254]

Answer:

On a coordinate plane, a trapezoid has points (0, 0), (0.5, 2), (1, 2), (1.5, 0).

Step-by-step explanation:

The given trapezoid has vertices at

(0, 0), (1, 4), (2, 4), (3, 0).

We want to choose from the given options the trapezoid with a scale factor between 0 and 1.

If a scale factor of a dilation is between 0 and 1, the size of the image trapezoid will be smaller than the preimage.

When we analyze the coordinates carefully, the answer is, a trapezoid has points (0, 0), (0.5, 2), (1, 2), (1.5, 0).

The reason is that, when we multiply the coordinates of (0, 0), (1, 4), (2, 4), (3, 0) by 0.5, we obtain (0, 0), (0.5, 2), (1, 2), (1.5, 0).

Hence the scale factor is 0.5 and this is between 0 and 1.

A class has 30 students,17 have taken science,19 have taken arts and two students have enrolled in any course. How many students

Bess [88]

Let x = number of students enrolled in both Science and Arts.

Then the number of students taking Science only is 17 – x and,
the number of students taking Arts only is 19 – x.

We know that
Total # of students in class = # Science only + # Arts only + Both Arts & Sciences + # Any
= (17 – x) + (19 – x) + x + 2
= 38 + x

This should be equal to 30 as given. So,
38 – x = 30

Subtract 38 from both sides:
–x = –8

So x = 8.
