Answer should be:

y = -3x - 3

Answer:

The equation is y = - 3x - 3

Step-by-step explanation:

Step 1:

Equations always start with y = (unless you are in grade 11) in which case you start with f(x) =

Step 2:

Use rise over run to find the slope (since its based on graph, if not there is a formula to find it when given coordinate points only)

So to use rise over run, you count how many squares upwards starting from a point that aligns in the graph (in this case the bolded dots)

So you start at (-2, 3) and count how many squares up or down to the next bolded dot (if its up its positive, if you have to go down then its negative).

Then once youve reached the same y-value as the the other dot, count how many squares to the right.

So in this case, you have to go down 6 times and right 2 times.

So as a fraction its -6/2 but that can be simplified to just -3

So thats the slope: -3

Step 3

then you need to find the y-intercept (where the line touches the y-axis)

Its easy: you can visually see that the line crosses at -3.

and the format for the equation is y = mx + b

m = slope

b= y-intercept

SO: y= -3x - 3

Answer:

-19 + 5x

Step-by-step explanation:

-0.20(95 -30x) - x = (-0.20*95) + [ (-0.20)*(-30x)] - x

                              = - 19 + 6x - x

                              = -19 + 5x

Answer:

3

Step-by-step explanation:

N*(2/3)=4

N=4*(3/2)=6

1/2 of N is 3

If the 2/3rd fraction of N is 4, then 1/2 fraction of N is 3.

Fractions are representations of equal parts of a whole number.

It is written as a/b, read as "a by b", and represents 'a' equal parts of 'b' equal parts.

'a' is called the numerator, and 'b' is called the denominator.

In the question, we are asked if 2/3 N is 4, then what is 1/2 of N.

We can represent the first fractional expression as:

2/3 of N = 4.

Now, we will solve the above expression by replacing of with multiplication.

2/3 * N = 4,

or, 2N/3 = 4.

Now, we will cross-multiply to get:

N = (4*3)/2 = 6.

Now, we are asked to find 1/2 of N.

We simply multiply (1/2) to the value of N:

(1/2)*N = (1/2)*6 = 3.

Thus, if the 2/3rd fraction of N is 4, then 1/2 fraction of N is 3.

Using a proportional relationship, it is found that the area is of 637 square inches when the radius is of 7 inches.

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:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

In this problem, the surface area of a balloon varies directly as the square of mits radius, hence:

[tex]S = kr^2[/tex]

The area is 325 in² when the radius is 5 in, hence we use it to find r.

[tex]S = kr^2[/tex]

[tex]325 = 25k[/tex]

[tex]k = 13[/tex]

Hence:

[tex]S = 13r^2[/tex]

When the radius is of r = 7 in, the area in square inches is given by:

[tex]S = 13r^2 = 13 \times 49 = 637[/tex]

Step-by-step explanation:

Trig identities:

[tex]\csc(\theta)=\dfrac{1}{\sin(\theta)}[/tex]

[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]

[tex]\cos(2\theta)=cos^2(\theta)-sin^2(\theta)[/tex]

[tex]\implies2cos^2(\theta)= \cos(2\theta)+1[/tex]

[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]

Therefore,

[tex]\frac{x+3}{x}[/tex] or x+3/x

Step-by-step explanation:

Answers:

24 quarters

22 nickels

==========================================================

Work Shown:

q = number of quarters

n = number of nickels

q+n = 46 coins total which solves to n = 46-q

25q = value of all the quarters in cents

5n = value of all the nickels in cents

25q+5n = value (cents) of all the coins of both types

25q+5n = 710 cents total = $7.10

-------------

Apply substitution.

25q+5n = 710

25q+5(46-q) = 710

25q+230-5q = 710

20q+230 = 710

20q = 710-230

20q = 480

q = 480/20

q = 24

They have 24 quarters

This yields 25*q = 25*24 = 600 cents = $6.00 so far.

Use that value of q to find n

n = 46-q

n = 46-24

n = 22

They also have 22 nickels.

They have an additional 5n = 5*22 = 110 cents = $1.10

In total, they have 6.00+1.10 = 7.10 dollars which confirms we have the correct coin counts. Also, q+n = 24+22 = 46.

Answer:

  x -5y = -20

Step-by-step explanation:

One way to write the equation for a line through two points is to use the slope formula. The slope is the same everywhere on a line, so the slope between the given points is the same as the slope between one of them and the general (x, y) point.

  m = (y2 -y1)/(x2 -x1)

  m = (5 -3)/(5 -(-5)) = (y -3)/(x -(-5))

  2/10 = (y -3)/(x +5)

  x +5 = 5(y -3) . . . . . . . multiply by 5(x+5)

  x -5y = -20 . . . . . . rearranged to standard form

The diameter of Christy's pool is 4 times larger than the other .-.

We know that for a circle of radius R the area is given by:

A = π*R^2

Let's say that:

Then we have the corresponding areas.

We know that:

A = 16*A'

Replacing the equations, we get:

π*R^2 = 16*(π*R'^2)

R^2 = 16*R'^2

If we apply the square root in both sides, we get:

√R^2 = √(16*R'^2)

R = 4*R'

This means that the radius of Christy's pool is 4 times larger than the one of Emily's pool.

And the same is for the diameter (twice the radius).

D = 2*R

D' = 2*R'

Then:

D = 2*R = 2*(4*R') = 4*(2*R') = 4*D'

The diameter of Christy's pool is 4 times larger than the other diameter.
