Answer:

Step-by-step explanation:

Let, x, represent the value of Dave's markers. You then make the equation (5x+x=18) because both markers combined is 18 and Sheila has 5 times the markers of Dave so her value would represent 5x. Solving the equation would get you x=3 BUT THAT IS THE VALUE OF DAVE'S MARKERS! The question asks for Sheila's with is 5*3. So the answer is 15 markers.

Solving polynomial(2y-4)(3y+6)

Answer:

6y² - 24

Step-by-step explanation:

Expand. Follow FOIL method. FOIL =

First

Outside

Inside

Last.

First, multiply the first term of each parenthesis:

2y * 3y = 6y²

Next, multiply the outside terms from both parenthesis:

2y * 6 = 12y

Then, multiply the inside terms from both parenthesis:

-4 * 3y = -12y

Finally, multiply the last terms of each parenthesis:

-4 * 6 = -24

Combine like terms:

6y² + 12y - 12y - 24

6y² + (12y - 12y) - 24

6y² - 24

6y² - 24 is your answer.

Write an inequality to represent the graph. a solid line passing through points 0 comma negative 7 and 3 comma negative 5 with s

lesantik [10]

Answer:

$y> \frac{2x}{3} -7$

Step-by-step explanation:

The equation of the straight line passing through the points (0,-7) and (3,-5) will be $\frac{y-(-7)}{-7-(-5)} =\frac{x-0}{0-3}$

⇒ $\frac{y+7}{2} =\frac{x}{3}$

⇒ $y=\frac{2x}{3} -7$ ......... (1).

Now, the inequality shades the upper portion of the straight line.

Therefore, the y value for the inequality will be more than y value for the equation corresponding to a fixed value of x.

Hence, the inequality equation will be $y> \frac{2x}{3} -7$ . (Answer)

On the coordinate plane, Kyle graphs a line that represents a proportional relationship between x and y

goldenfox [79]

Option D) (0, 0)

<h2>Explanation:</h2>

The complete question is:

_______________________________________

On the coordinate plane, Kyle graphs a line that represents a proportional relationship between x and y. Which point MUST be on the line?

A) (0, 1)

B) (1, 0)

C) (1, 1)

D) (0, 0)

_______________________________________

A proportional relationship between x and y can be written in a mathematical language as follows:

$y=kx$

For any non-constan k-value. As you can see, this k-value represents the slope of a line. Remember that the Slope-intercept form of a line is given by:

$y=mx+b \\ \\ m:Slope \\ \\ b:y-intercept$

In the case of $y=kx$ the y-intercept is zero, so the line passes through.

In conclusion, <em>Kyle's graph is a line that represents a proportional relationship between x and passes through point (0, 0)</em>
