PLEASE HELP 7TH GRADE MATH 24 POINTS

Answer:

Step-by-step explanation:

Let the number = x

x^3 = x^2 + 100

x^3 - x^2  +0x - 100 =0

a = 1

b = - 1

c = 0

d = -100

My calculator solves these kinds of questions. The answer is

x1 = 5                  Which we should be able to get without a special calculator

x2=-2+4i

x3 = - 2 - 4i

I doubt you need anything more than 5. If she is thinking of the complex numbers, she should be in a special class for people who think about such things  

Here is a graph of the problem.

Answer:

The second one from the top

Step-by-step explanation:

     This table shows a proportional relationship between x and y because when y is multiplied by 7, we get x.

     (or when x is divided by 7 we get y, my thoughts first go to the multiplication)

     Hope this helps, have a nice day! :D

Answer:

Step-by-step explanation:

y = -x + 7 is a linear equation in slope-intercept form, y = mx + b.

The slope (m) measures the unit changes in the output (y ) for each one-unit change in the input (x) value.

b =  the y-ccordinate of the y-intercept, (0, b). The y-coordinate, b, is what you will use for the slope-intercept form. The y-intercept is the point on the line where it crosses the y-axis.

To graph y = -x + 7, use the slope, m = -1 (down 1 unit, run 1 unit), and the y-intercept,  (0,7) to plot points on the graph to connect a line with.

The equation, x = 3 represents a vertical line with an undefined slope. A vertical line has undefined slope because all points the line have the same x-coordinate.  Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as using the slope formula, m = (y₂ - y₁)/(x₂ - x₁), as it will involve a division by zero (which consitutes an undefined operation).        

To graph x = 3, choose any point on the graph that has an x-coordinate of 3, then draw a vertical line from there.

The given equation has a solution that occurs at point (3, 4). Attached is an edited screenshot of the image that you uploaded.

Answer:

There is no common ratio.

Step-by-step explanation:

I divided each number in the sequence from the number preceding it and the answer was not one of the numbers in the series. this would mean that there is no common ratio. (please correct me if i am wrong)

Answer:

She can bake 3/8 of a batch of cupcakes.

Step-by-step explanation:

If she only has 1/2 of the flour and you are trying to find the fraction of a batch she can make, you are essentially trying to figure out what is 1/2 of 3/4, which is basically just multiplying 1/2 by 3/4. This would get you the answer of 3/8. Hope this helps:)

Answer:

y = 10x + 50

Step-by-step explanation:

Answer:

y=4500x+32000

Step-by-step explanation:

If they are increasing at a constant rate of 4500 then that is the coefficient of x, and if they received a 32000$ donation then that is the y-intercept so you add that to 4500x to get this equation.

Answer:

The range is 13.

Step-by-step explanation:

The definition of the range is to subtract the largest number from the smallest number. Looking at this set of numbers, the largest number is 30, and the smallest number is 17. When you subtract 30 - 17 you end up with 13.

Answer:

y=[tex]\frac{24-17t}{3h}[/tex]

Step-by-step explanation:

Hi there!

We are given the formula 17t+3hy=24

We want to make y the subject of the formula, which also means that we want to solve the equation for y

To do that, we'll need to isolate y on one side, much like solving for an equation with real numbers.

Let's first subtract 17t from both sides.

17t+3hy=24

-17t         -17t

___________

3hy=24-17t

Now on the left, we have 3hy, but remember; we want just y by itself. Once again, similar to solving an equation with real numbers, we can pretend that 3h is the coefficient of the equation, while y is our variable.

So to get y by itself, we'll need to divide both sides by 3h

y= [tex]\frac{24-17t}{3h}[/tex], which can also be written as y=[tex]\frac{8}{h} -\frac{17t}{3h}[/tex]

Hope this helps!

Step-by-step explanation:    I TOOK THE QUIZ AND GOT 100%

Answer:

Step-by-step explanation:

Solve the  y

y -3 = 1/2(x + 2)

y =  1/2(x + 2) + 3                Add

Pick  points that you wish to substitute for x values.

       x = 0                                   x  = 2                                       x = 4

  y = 1/2(x + 2) + 3                y = 1/2(x + 2) + 3               y = 1/2(x + 2) + 3

  y = 1/2(0 + 2) + 3               y = 1/2(2 + 2) + 3               y = 1/2(4 + 2) + 3

    y = 1/2(2) + 3                    y = 1/2(4) + 3                     y = 1/2(6) + 3

    y = 1 + 3                            y = 2 + 3                            y = 3 + 3

    y = 4                                 y = 5                                  y = 6

Locate the following point on  graph (x, y); (0, 4), (2, 5), (4, 6)  

The dimension of the truck is 8ft by 6t by 2ft

The volume of the rental cargo is expressed according to the formula;

V = lwh

l is the length of the box

w is the width

h is the height

Given the following parameters

V = 96ft^3

h = 8ft

Substitute into the formula

96 = 8lw

lw = 96/8

lw = 12

The other dimensions of the tuck will be 2ft and 6ft respectively

Hence the dimension of the truck is 8ft by 6t by 2ft

Answer:

m ∠DCA

m ∠CAD = 56

m ∠CBA = 83°    

Step-by-step explanation:

A parallelogram is a polygon with two pairs of parallel lines

m ∠CDA = m ∠CBA = 83°       Opposite angles in a parallelogram are =    

m ∠CAD = m ∠ACB  = 56°     CB ║ DA and alternating interior angle are =

m ∠DCA = 180°                           The sum of the angles in a triangle = 180°

m ∠ADC + m ∠CAD + m ∠DCA = 180            Parts of the triangle

       83° +  56° + m ∠DCA = 180                     Substitution

            139° + m ∠DCA = 180°

                  m ∠DCA = 180° - 139°

                   m ∠DCA = 41°

Answer:

y = 86

Step-by-step explanation:

We know the slope is 5 so we can write our equation like this:

y = 5x + b

Since we know that (5, 6) is on our equation, we can substitute it into our equation:

6 = 5(5) + b

b = 6-25 = -19

Now we know our equation is y = 5x - 19

Next, we plug in 21 for x to find our y-value:

y = 5(21)-19 = 105-19 = 86
