Answer:

-1/2

Step-by-step explanation:

You would do m which represents slope. So m = y2 - y1/x2-x1. I then plugged the points in and got -1/2. Did this help???

The length of a rectangle is 7 more than the width. The area is 744 sqaure yards, find the length and width of the rectangle

AVprozaik [17]

Answer:

Length of rectangle is 31 yards and Width is 24 yards.

Given:

The length of a rectangle is 7 more than the width.
The area is 744 sqaure yards

Solution:

Let's assume Width of rectangle be x and Length of rectangle be x + 7 respectively.

Using formula

$\\ \: \: \: \: \pink{ \dashrightarrow \: \: \: \: \sf { \underbrace{Area_{(Rectangle)} = Length × Width }}} \\ \\$

On Substituting the required values, we get;

$\\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x)(x + 7) = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 31x - 24x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x(x + 31) - 24 (x + 31) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x + 31)(x - 24) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x = 24 \: or \: - 31 \\ \\$

As we know that width of the rectangle can't be negative. So x = 24

<u>Hence</u>,

Width of rectangle = x = 24 yards
Length of the rectangle = x + 7 = 31 yards

$\therefore$ Length of rectangle is 31 yards<u> </u>and Width is 24 yards.

The sum of the ages of Levi and Monique is 76 years. 8 years ago, Levi's age was 3 times Monique's age. How old is Levi now?

andreev551 [17]

Answer:

Levi is 53 yrs now

Step-by-step explanation:

sum = 76yrs

Levi = 3x -8

Monique = x - 8

8yrs ago

sum= 76 - 8 - 8( the two 8s are from each of the two brothers).

= 60yrs

Levi=3x

Monique=x

3x + x = 60

4x = 60

x = 15yrs

Levi = 3x

= 15 x 3

= 45 yrs(8yrs ago)

now = 45 + 8

= 53yrs now

Monique = x

= 15

now = 15 + 8

23yrs now
