Given:

The compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].

To find:

The solution for the given compound inequality

Solution:

We have, compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].

For [tex]2x-3 < 7[/tex],

Add 3 on both sides.

[tex]2x < 7+3[/tex]

[tex]2x < 10[/tex]

Divide 2 on both sides.

[tex]x< 5[/tex]            ...(i)

For [tex]5-x \leq 8[/tex],

Subtract 5 from both sides.

[tex]-x \leq 8-5[/tex]

[tex]-x \leq 3[/tex]

Divide both sides by -1. So, the sign of inequality is changed.

[tex]x \geq -3[/tex]            ...(ii)

Using (i) and (ii), we get the solution of given compound inequality as

[tex]x \geq -3[/tex]  and [tex]x< 5[/tex]

Therefore, the correct option is D.

Answer:

-2265

Step-by-step explanation:

First, we replace x with 20.

[tex]f(20)=-5*20^2-13*20-5[/tex]

Then, we evaluate.

The * stands for multiplication.

[tex]f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265[/tex]

[tex]f(20) = - 5 \times {20}^{2} - 13 \times 20 - 5 \\ [/tex]

[tex]f(20) = - 5 \times 400 - 260 - 5[/tex]

[tex]f(20) = - 2000 - 260 - 5[/tex]

[tex]f(20) = - 2265[/tex]

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

For us to compare negative fractions, we must know that higher negative fractions are less than the smaller ones

Given the fractions  −5/6 and −13/15

First we will need to write this fractions as percentage:

-5/6 * 100 = -500/6 = -83.3%

-13/15 * 100 = -1300/15 = -86.67%

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

Answer:

14

Step-by-step explanation:

(r + 3) + (4r - 28) = 45

5r - 25 = 45

5r = 70

r = 14

if you wanna check

14 + 3 + 4(14) - 28 = 45

45 = 45

Step-by-step explanation:

No she is not correct.

Since both angles have the same measurement you set them equal to each other as so & solve for x

2x+90= x+95

x+90=95

x=5

In order to find the angle measurements you plug in 5

2(5)+90

10+90

= 100 degrees

Supplementary angles add up to 180 degrees so the angle next to the 100 degree one is 80 degrees

The distance formular is represented as :

d = √(x2 - x1)² + (y2 - y1)²

Let d = distance

The vertical and horizontal coordinates as x and y respectively ;

The square root of the sum of square of the difference between the x and y coordinates ;

Distance = √(x2 - x1)² + (y2 - y1)²

Hence, d = √(x2 - x1)² + (y2 - y1)²
