Answer:

C. 6

Step-by-step explanation:

So it says read less thann 25 books --> that means the numbers are 13,14,14,16,19,21,21,22,23, and 24 --> a total of 10 numbers

Then it says read more than 35 books --> that means the numbers are 37,41,42,43 --> a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 = 10 - 4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.

Please help me with both of these questions I’m supper stuck

Answer:

ONE SOLUTION

Step-by-step explanation:

When two points on a line are given, the equation of the line is given by the formula:

$\frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}$

where $(x_1, y_1)$ and $(x_2, y_2)$ are the points on the line.

Here, the first set of points are: $(-1, 3)$ and $(0, 1)$ .

Therefore, $(x_1, y_1) = (-1, 3)$ and $(x_2,y_2) = (0, 1)$ .

The line passing through this is given by:

$\frac{y - 3}{1 - 3} = \frac{x + 1}{1}$

$\implies y - 3 = -2x - 2$

∴ 2x + y - 1 =0

Now, for the second line, the points are:

$(x_1, y_1) = (1, 4)$ and $(x_2, y_2) = (0, 2)$ .

Therefore, $\frac{y - 4}{-2} = \frac{x - 1}{-1}$

$\implies -y + 4 = -2x + 2$

∴ 2x - y + 2 = 0

Now, to determine the number of solutions the two equations have, we solve these two equations,

Adding Eqn(1) and Eqn(2) we get:

4x = -1

$\implies x = \frac{-1}{4}$

And $y = \frac{3}{2}$ .

Since, we arrive at unique values of 'x' and 'y', we say the lines have only one unique solution.

EFGH is a dilation and rotation of ABCD.
The shortest side of the smaller figure corresponds to the shortest side of the largest one, the largest sides correspond, etc.
AB -> EF
BC-> FG
CD->GH
DA->HE

Corresponding angles are congruent in dilations.
Angle A = angle E
Angle B= angle F
Angle C = angle G
Angle D = angle H

Explanation:
EFGH is a dilation and rotation of ABCD. If you take one of the figures, rotate it 180 degrees, and lay it on top of the other figure, the corresponding sides and angles will line up.
