find DF if D is between E and F, ED = 6x-4 , DF =3x+5 and EF= 46

Answer:

6 quarters and 9 nickels

Step-by-step explanation:

alright so this took me like an hour or two to figure out cause I'm stubborn. but I wanted to give an in depth answer

..

1) first we need to know how to write it.

___=___+___

1.95 is the full value of all of the coins so it goes here. (___)=___+___

1.95=___+___

We will use q for number of quarters and n for number of nickels. the value of a quarter .25 and the value of a nickel is .05. put the value of a quarter here. ___=(___)+___

1.95=.25q+___

we will put the value of the nickel here ___=___+(___)

1.95=.25q+.05n

now that we know how to write it, we can move onto step two.

2) figuring out what variable n is

n=___

Since we know that there are three more nickels than quarters, we can start to solve this equation.

n=q+3

3) change (n) to (q+3). dont forget to use parenthesis!

1.95=.25q+.05(q+3)

4) i forget what its called but multiply .05 throughout your parenthesis. ill show you.

1.95=.25q+.05(q+3)

                  .05*q= .05q and .05*3=.15

1.95=.25q+.05q+.15

5) add variables together.

1.95=.30q+.15

6) subtract .15 from both sides to get rid of it.

1.95=.30q+.15

-.15            -.15

1.80=.30q

7) divide .30 from both sides to isolate the q and get the answer of quarters

1.80=.30q

/.30 /.30

6=q

8) add three to the number of quarters to get the number of nickels.

6+3=9 nickels

Here we need to create and solve a system of equations to find the number of coins in the piggy bank.

We will see that there are 6 quarters and 9 nickels.

let's define the variables:

x = number of nickels in the piggy bank

y = number of quarters in the piggy bank.

Knowing that the total value of the coins in the piggy bank is $1.95, then we have:

x*$0.05 + y*$0.25 = $1.95

We also know that there are 3 more nickels than quarters, then we also have:

x = y + 3

Then the system of equations is:

x*$0.05 + y*$0.25 = $1.95

x = y + 3

To solve this, we can see that x is isolated in the second equation, so we can replace it in the other equation to get:

(y + 3)*$0.05 + y*$0.25 = $1.95

Now we can solve this for y:

y*$0.05 + 3*$0.05 + y*$0.25 = $1.95

y*$0.30 + $0.15 = $1.95

y*$0.30 = $1.95 - $0.15 = $1.80

y = ($1.80)/($0.30) = 6

So we have 6 quarters.

Then the number of nickels is given by:

x = y + 3 = 6 + 3 = 9

x = 9

There are 9 nickels.

Answer:Let n = the smallest integer

Then the other integers are n+1, n+2, n+3 and n+4

Sum = n + n+1 + n+2 + n+3 + n+4 = 5n + 10 = 5(n + 2)

So the sum is always divisible by 5, for any value of n

Step-by-step explanation:

The vertical line (V) and horizontal line (H) intersect at point C are V: x = 5.5; H: y = –2.5 option (D) is correct.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

From the graph,

The coordinate of point C is (5.5, -2.5)

The vertical line (V) and horizontal line (H) intersect at point C are:

x = 5.5 (Vertical line)

y = -2.5 (Horizontal line)

Thus, the vertical line (V) and horizontal line (H) intersect at point C are V: x = 5.5; H: y = –2.5 option (D) is correct.

[tex]3x-y=14[/tex]

Step-by-step explanation:

To convert an equation into standard form, we want to get into the form [tex]ax + by = c[/tex].

If we have [tex]y=3x-14[/tex], our first step is to get the x term on the left side. We can do this by subtracting 3x from both sides.

[tex]-3x + y = -14[/tex]

I find it easier now to just divide both sides by -1, so that we have a more consistent equation.

[tex]3x - y = 14[/tex]

Answer: 4x³+29x²+40x-48

Step-by-step explanation:

To solve f(x)·g(x), you multiply them together.

(4x²+13x-12)(x+4)                           [distribute by FOIL]

4x³+16x²+13x²+52x-12x-48          [combine like terms]

4x³+29x²+40x-48

Now, we know that f(x)·g(x)=4x³+29x²+40x-48.

Answer: 4x³+29x²+40x-48

Step-by-step explanation:

The product of two functions=f(x)·g(x)=fg(x)

Use FOIL method to simplify expression.

 f(x)·g(x)

=(4x²+13x-12)·(x+4)

=4x³+16x²+13x²+52x-12x-48

=4x³+29x²+40x-48

Answer: If you trying to find the distance [tex]d=\sqrt{16}[/tex] or 4. If you trying to find midpoint its MP= (-3,2)

Step-by-step explanation:Distance formula[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{2})^{2} }[/tex]

[tex]d=\sqrt{(-2-(-4))^{2}+(3-1})^{2} }[/tex] -2-(-4)=2     3-1=2

[tex]d=\sqrt{2^{2}+2^{2} }[/tex] 2 squared is 4

[tex]d=\sqrt{4+4}[/tex]  equals [tex]d=\sqrt{16 }[/tex] or 4 simplyfied

Midpoint formula [tex]MP= (\frac{x_{1}+x_{2} }{2}), (\frac{y_{1}+y_{2} }{2} )[/tex]

[tex]MP= (\frac{-4+-2 }{2}), (\frac{1+3 }{2} )[/tex] -4+-2=-6     1+3=4

[tex]MP= (\frac{-6}{2} ), (\frac{4 }{2} )[/tex] -6/2= -3    4/2= 2

[tex]MP= (-3,2)[/tex]

Hey there!!

Given,

[tex] \frac{24}{28} [/tex]

We generally divide the fraction from smallest prime number if they are divisible and make it in a simplest form.

So, let's work with it.

[tex] = \frac{24}{28} [/tex]

Divide it by 2.

=[tex] \frac{12}{14} [/tex]

See, it's again divisible by 2, so again divide it by 2.

=[tex] \frac{6}{7} [/tex]

Now, here 6 can be divided by 2, 3 but 7 can't be divided, as it is a prime number.

So, the answer is option D.
