Answer:

x = 4

Step-by-step explanation:

Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.

Taking [tex]-24x=6x^2[/tex], we can simplify this just to make it a bit more professional, to say [tex]6x^2=-24x[/tex] (We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).

Now, we can really start by dividing both sides by 6, to get [tex]x^{2} =-4x[/tex], and then divide both sides by x to get [tex]x=4[/tex].

So, the answer of this quadratic equation is x = 4.

Answer:

13 dollars per hour ! ^^

Step-by-step explanation:

According to the proportional relationship shown by the graph, the rate of change is of 13 dollars per hour.

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality, which is also the rate of change.

Considering the graph, the rate of change, in dollars per hour, is given by:

k = 65/5 = 26/2 = 13.

Answer:

80 yd^2

Step-by-step explanation:

Since the formula for squares is s^2, we can use this to set up an equation, which is

s^2=400

If we square root this, we get

s=20

The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

Answer:  28x  + 15y = 131   and x + y =  7   where x is the number of Dress shirt and y is the number of T-shirt.

Step-by-step explanation:

We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.

We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal  131.  Also, he bought 7 total shirts so x plus y has to equal 7.

28x  + 15y = 131  

x + y =  7

Note: it says don't solve so I didn't solve but if you want to solve use these equations.

Answer:

3/2

Step-by-step explanation:

Given y = 2x + 5, let's rewrite the equation in terms of x;

y = 2x + 5 => Bring 5 to the other side

2x = y - 5 => Divide either side by 2

x = (y - 5)/2

If we want to take the inverse, simply swap the variable's positions...

We have y = (x - 5)/2

Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1

f^-1(8) = (8 - 5)/2 = 3/2

Solution: 3/2

Answer:

-1/3 x 9x -1/3 x 30 + 2

-3x -10 +2

-3x - 8

Step-by-step explanation:

this is a distributive type of problem you distribute the -1/3 to the 9x and the 30 by distribute i mean multiply. if you dont know how to multiply this use the calculator but you multiply it by the 2 pairs of numbers in the parenthesis and then you just add the 2

multiply the percent by the money

Step-by-step explanation:

Order these numbers from largest at the top, to smallest at the bottom.

1.57x10^-4

4.5x10^3

1.3x10^1

987

We can see that:-

The exponent with highest power is the largest number.

Here, the largest number is

[tex]1.3 \times 10 ^3[/tex]

Next, is [tex]987[/tex]

Smaller than this, next is :-

[tex]1.3 \times 10^1[/tex]

A number with negative power is smaller.

So, last is

[tex]1.57 \times 10^{-4}[/tex]
