Answer:

2/3

Step-by-step explanation:

We know the value of y, so substitute y into the equation:

3x + (-4 + 11) = 9 --> remove parentheses

3x - 4 + 11 = 9

3x + 7 = 9 --> subtract 7 from 9

3x = 2 --> divide

x = 2/3

Arrange the hyperbolas in increasing order of the horizontal widths of their asymptote rectangles.
almond37 [142]

The  increasing order of the horizontal widths of their asymptote rectangles is dependent on the values gotten from  y = ± x.

<h3>What is a Hyperbola?</h3>

This is defined as a two-branched open curve formed by the intersection of a plane perpendicular to the bases of a double cone.

The rectangular hyperbola has two asymptotes which are defined as y = ± x in this scenario.

The two rectangles shown have equal areas. Find the value of x
Tema [17]

Answer:

x=18

Step-by-step explanation:

We need to find the areas of the rectangles

1st rectangle

A= l*w

A = (2x+4)*9

   = 18x+36



2nd rectangle

A = l*w

   = 15*(3x-30)

    = 45x-450


Since the area of the rectangles are equal, we set these two equations equal

18x+36 = 45x-450

Subtract 18x from each side

18x-18x+36 = 45x-18x-450

36 = 27x-450

Add 450 to each side

36+450 =27x

486 = 27x

Divide by 27 on each side

486/27 = 27x/27

18=x

Varvara68 [4.7K]

Answer:

\frac{6}{8} or \frac{3}{4}

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

2\frac{3}{8}-1\frac{5}{8}=\frac{19}{8}-\frac{13}{8}

Since the two fractions have the same denominator, just subtract the numerators.

\frac{19}{8}-\frac{13}{8}=\frac{6}{8}

If required, rewrite the fraction in simplest form.

\frac{6}{8}=\frac{3}{4}

Writing and Solving an Equation to Find Negative Integers Two negative integers are 5 units apart on the number line, and their
Shtirlitz [24]

Answer:

-23

Step-by-step explanation:

Let first negative integer = x

The second = x +5

Their product = 126, hence,

x * (x +5) = 126

x^2 + 5x = 126

x^2 + 5x - 126 = 0

Two numbers whose product gives - 126 and sun gives 5

x(x + 14) - 9(x+14) =0

(x - 9) = 0 or (x + 14) = 0

x = 9 or x = - 14

Since x is said to be a negative integer,, the our x = - 14

First integer = - 14

Second integer = (x + 5) = (-14 + 5) = - 9

Sum of both integers :

-14 + - 9 = - 23
