Find the gradient of the line Joining the points p(-2,6) and Q(3,-2)​

Answers

Answer:

[tex] - \frac{8}{5} [/tex]

Step-by-step explanation:

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

(x₁, y₁) is the 1st coordinate while (x₂, y₂) is the 2nd coordinate.

Gradient of the line

[tex] = \frac{6 - ( - 2)}{ - 2 - 3} [/tex]

[tex] = \frac{6 + 2}{ - 5} [/tex]

Which values are restrictions on the domain of f(x)?
theres also an answer option of x=5 but it wouldnt fit in the picture

Answers

2&3

Step-by-step explanation:

You have to factorise the second equation and you have to solve it. so you have x²-2x-3x+6

x(x-2)-3(x-2)

(x-2)(x-3)=0

Then you have to find x for each equation.

x-2=0

x=2

x-3=0

x=3

So the restricions are 2&3.

Describe a way to make the arithmetic problem 45% x 680 mentally

Answers

Answer:

306.

Step-by-step explanation:

Firstly, we are aware 100% of 680 is obviously 680,

Next, we know half of a 100% is 50% therefore half of 680 is 340.

Then, we know 45% is 5% less than 50%

To find 5% of a number mentally, divide it by 10 as 100÷5=20

680÷20=34

Lastly 50% subtracted by 5%: 340-34=306.

Now we know, 45% of 680 is 306.

Hope this helps.

Step-by-step explanation:

First convert the equation -x+y=-5 into slope intercept form. Graph the line by plotting the y-intercept first, then another point using the given slope.

Answers

Step-by-step explanation:

-x + y = -5

Transform to slope-intercept form, y = mx + b:

-x + x + y = x - 5

y = x - 5 (Slope-intercept form where m = 1, b = -5).

Plot the y-intercept (0, -5) on the graph. Using the "rise over run" of the slope, m = 1, the next point will be: (1, -4).

I also plotted other points (please see the attached screenshot of the graph).

Scarlett has 14 gallons of gas in her car at the beginning of a trip. Every hour Scarlett drives, she uses 2.5 gallons of gas. Answer the questions below regarding the relationship between the gallons of gas remaining in the tank and the total hours driven.

Answers

Answer:N(5)=1.5

Step-by-step explanation:The independent variable x represents the Number of hours driven and the dependent variable is the gallons of gas remaining, because the gallons of gas remaining depends on the number of hours driven.

A function relating these variables is Nx=14-2.5

So N(5)=1.5 meaning 5 hours of driving will result in 1.5 gallons left in the tank.
