Answer:

For the equation y = -6.75x + 8.54 the slope is -6.75 and the y-intercept is 8.54.

Explanation:

The slope intercept equation is y = mx + b where m = slope and b = y-intercept.

Hey! Slope is the coefficient of the x variable: in this case: -6.75.

The y- intercept is the value when x = 0 (also the number without the x variable on it), which is 8.54.

Hope this helps!

Can someone please. Heck my answer if it’s wrong please answer it correctly and please show work first pic is the question and 2

Answer:

Correct

Step-by-step explanation:

4y = 3x Divide each side by 4

4y ÷ 4 = 1y

3x ÷ 4 = 0.75x

12y = 9x Divide each side by 12

12y ÷ 12 = 1y

9x ÷ 12 = 0.75x

We can see in both equations that 1y = 0.75x

(1y = just y) So the constant of proportionality can be written as y = 0.75x

All of your explanations and descriptions are accurate.

Change the width 20/16 inches to a mixed numeral in simplest form.

Iteru [2.4K]

Answer:1 and 1/4

Step-by-step explanation:

Okay, let's see the given: 20/16

So, we can take out 16 from the top to make it 1 4/16

Now, we can simplify that by dividing the top and bottom by 2: 1 2/8

We can simplify that again to get 1 1/4

So the answer is 1 and 1/4

The area of rectangular garden is $8 x^{2}+4 x-24$

<h3><u>Solution:</u></h3>

Given that a rectangular garden has width = 4x - 6

Length of rectangular garden = 2x + 4

To find: area of rectangular garden

<em><u>The area of rectangle is given as:</u></em>

$\text {area of rectangle }=\text { length } \times \text { width }$

Substituting the values in given formula,

$\begin{array}{l}{\text { area of rectangle }=(2x+4) \times(4x-6)} \\\\ {=8 x^{2}-12 x+16 x-24} \\\\ {=8 x^{2}+4 x-24}\end{array}$

Thus the area of rectangular garden is $8 x^{2}+4 x-24$

Help! I need help with finding the value of x.

Dmitry_Shevchenko [17]

Answer:

x = 18.64

Step-by-step explanation:

use tan:

⇒ tan = $\frac{opposite}{adjacent}$

⇒ tan 46 = $\frac{18}{x}$

tan of 46 is 1.0355

⇒ 1.0356 = $\frac{18}{x}$

multiply 18 on both sides

⇒ 1.0355 x 18 = $\frac{18}{x}$ x 18

⇒ 18.64 = x

Select the graph that best represents the solution set for 5x+1≤11

maksim [4K]

$5x+1 \le 11$

$5x+1-1 \le 11-1$ Subtract 1 from both sides

$5x \le 10$

$\frac{5x}{5} \le \frac{10}{5}$ Divide both sides by 5 to isolate x

$x \le 2$

To graph this, draw out a number line. Plot a closed circle at 2 on the number line. The closed circle indicates we include this value in the solution set. This is the endpoint. We shade to the left of the endpoint to represent all of the values smaller than 2. The endpoint is included because of the "or equal to" portion of the inequality sign.
