Answer:

You're wrong, it's the bottom left

Step-by-step explanation:

x^2-49 is a difference of squares so it factors into (x+7)(x-7) which obviously cancels out with the denominator leaving x-7 left. This is the line you should graph, but keep in that x+7 is still in the denominator so x cannot be equal to -7 which means that this point should be be on the line which leaves the answer to be the one on the bottom left.

Answer:

[tex]x + 7[/tex]

is the answer because 7×2+42x-49

Answer:

The expression to represent number of cherries Leslie ate = ( x + [tex]\frac{6}{9}[/tex] ) pound.

Step-by-step explanation:

As given,

Mary ate cherries = x pound

And

Leslie ate [tex]\frac{6}{9}[/tex] more.

⇒Leslie ate cherries = ( x + [tex]\frac{6}{9}[/tex]  ) pound.

Answer:

60

Step-by-step explanation:

so first you multiply 2 times 5 =15 and the we do 15 times six which is 90 and then subtract one and keep subtracting util you get to 60

Answer:

x=-1

Step-by-step explanation:

2(x-5)=6(x-1)

2x-10=6x-6

-4x-10=-6

-4x=4

x=-1

Answer:

6 1/6.

Step-by-step explanation:

That would be 6 1/6. Because 37/6 = 6 remainder 1, which is 1/6, so 6 1/6.

Answer:

1.5 or 1 1/2 pounds of candy

Step-by-step explanation:

First, divide 2 into 4 equal pieces. You do this because of the denominator in 3/4.

2 divided by 4= 0.5

Then 0.5 times 3 because of the numerator in 3/4.

0.5 times 3= 1.5

You can convert this into the fraction 1 1/2 or you can leave it a 1.5

Hope this helps!

Answer:

the money left is $487.50

Step-by-step explanation:

The computation of the money left is shown below:

= Total money - spent money

= $750 - $750 × 35%

= $750 - $262.50

= $487.50

Hence, the money left is $487.50

We simply deduct the spent money from the total money

Answer:

192.5 in³

Step-by-step explanation:

The cardboard is 10 by 20 before removing a square from each end. Assuming that the square is x inches wide. Therefore, the 20 in side gets reduced by x inches on both sides, or say it becomes 20 - 2x inches. On the other hand, the 10 in side is also reduced by 2x. The x value we get happens to be the height of the box when the sides are folded up.

Thus the volume V = lbh =

V = (20-2x)*(10-2x)*(x)

V = 4x³ - 60x² + 200x

On differentiating, we have dv/dx to be

dv/dx = 12x² - 120x + 200

Using general formula to find the roots of this equation, we can solve that x = 7.886 and x = 2.113

This roots we got are possible values of x, the square we cut. Since 7.886 * 2 = 15.772 inches, this is more than the 10 inch side, henceforth x = 2.113 inches.

You cut 2.113 inches from each corner to obtain the maximum volume.

The sizes of the cubes are

20 - (2 * 2.113) = 15.774

10 - (2 * 2.113) = 5.774

2.113

The volume of the cube is 15.774 * 5.774 * 2.113 = 192.5 cubic inches.

Step-by-step explanation:

Answer:

[tex]y=\frac{1}{2}x-\frac{13}{2}[/tex]

Step-by-step explanation:

Move all terms not containing  y  to the right side of the equation.

[tex]y = \frac{x}{2}-\frac{13}{2}[/tex]

Rewrite

[tex]y=\frac{1}{2}x-\frac{13}{2}[/tex]

Use the slope-intercept form to find the slope and y-intercept.

Slope: [tex]\frac{1}{2}[/tex]

y-intercept: [tex](0, -\frac{13}{2})[/tex]
