What is the equation for the line that passes through (-4,-3) and (-2,3)

alekssr [168]

Answer: $y=3x+9$

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

We can calculate the slope of the line with this formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Given these points:

$(-4,-3)\\\\ (-2,3)$

We can identify that:

$y_2=-3\\y_1=3\\\\x_2=-4\\x_1=-2$

Then, the slope is:

$m=\frac{-3-3}{-4-(-2)}=3$

Now we have to substitute the slope and one of the points into $y=mx+b$ and solve for "b":

$3=3(-2)+b\\\\3+6=b\\\\b=9$

Then, the equation of this line is:

$y=3x+9$

A candy box is made from a piece of cardboard that measures 15 by 9 inches. Squares of equal size will be cut out of each corner

Valentin [98]

Answer:

1.82 inches

Step-by-step explanation:

Let the size of square piece cut from the corner is d.

So, the length of the box is 15 - 2y

width of the box is 9 - 2y

height of the box is d.

Volume of the box

Volume = length x width x height

V = (15 - 2y)(9 - 2y)y

V = 4y³ - 48y² + 135y

Differentiate with respect to y.

$\frac{dV}{dy}=12y^{2}-96y+135$

It is equal to zero for maxima and minima

$12y^{2}-96y+135=0$

$y=\frac{96\pm \sqrt{96^{2}-4\times 12\times 135}}{24}$

So, y = 1.82 in or 6.2 in

Now

$\frac{d^{2}{V}}{dy^{2}}=24y-96$

For y = 1.82 in, it is negative

and for y = 6.2 in, it is positive

So, the volume of the box is maximum if the height of the box is 1.82 inch.

Thus, the size of the square cut from each of the corner is 1.82 inches.

The length of a rectangle is three times longer than its width. The perimeter of the rectangle is 16 feet. If x represents the w

scoray [572]

<span>Given that x represents the width of the rectangle and that the length of the rectangle is three times longer than the width. Then the length is 3x. The perimeter of a rectangle is given by 2(length + width) = 2(3x + x) = 2(4x) = 8x. The perimeter of the rectangle is 16 feet. Therefore, the required equation is 8x = 16. </span>

4x – 2y = –1 3 and –4x + 4y = –2 what does x and y equal?

Harrizon [31]

Answer:

X = -7 and y = -7.5

Step-by-step explanation:

Use substitution. Let’s try to get x by itself in the second question since it seems easier.

-4x + 4y = -2

-4x = -2 -4y

x = 1/2 + y

Subsitute that into the other equation for y.

4x -2y = -13

4(1/2 + y) - 2y = -13

2 + 4y -2y = -13 # Use the distributive property

2y = -15 # put together like terms

y = -7.5

Then plug it into the x formula

x = .5 -7.5

x = -7
