Answer:

11 months

788 disc

Step-by-step explanation:

Let

x = number of months

Fry's Electronics;

= 920 - 12x

Blu-ray discs:

= 502 + 26x

Equate both equations

920 - 12x = 502 + 26x

920 - 502 = 26x + 12x

418 = 38x

x = 418/38

x = 11 months

number of months = 11

Substitute 11 into any of the equation

Fry's Electronics;

= 920 - 12x

= 920 - 12(11)

= 920 - 132

= 788 disc sold in that months

Answer:

Step-by-step explanation:

point-slope equation of the line: y+1 = -(x-3)

rearrange to solve for y:

y+1 = -x+3

y = -x + 2   slope-intercept form

Answer:

y = -x + 2

Step-by-step explanation:

We are given that a line has a slope of -1 and passes through the point (3, -1)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept

As we are already given the slope, we can immediately plug its value into y=mx+b.

Replace m with -1 in y=mx+b.

y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).

Now we need to find b.

As the equation passes through the point (3, -1), we can use it to help solve for b.

Substitute 3 as x and -1 as y.

-1 = -3 + b
Add 3 to both sides

2 = b

Substitute 2 as b in the equation so far.

y = -x + 2

Answer:

C is the answer

Step-by-step explanation:

The equation of the red graph is [tex]x^{2} +2[/tex].

The equation of the parabola whose vertex is (h, k) is

[tex]y = a(x-h)^{2} + k[/tex]

According to the given question.

We have a graph for the function f(x) and g(x).

[tex]f(x) =x^{2}[/tex]..(i)

⇒ the equation of parabola whose vertex is (0, 0)

Since, we know the standard form of the  equation of parabola is

[tex]y = a(x-h)^{2} +k[/tex]

Substitute h = 0 and k = 0 in the above equation.

⇒ [tex]y = a(x-0)^{2} +0[/tex]

⇒ [tex]y = ax^{2}[/tex]..(ii)                          (where, y = f(x))

On comparing the first two equations we get a = 1.

From the graph we can see that g(x) is a equation of parabola, whose vertex is (0, 2).

Therefore, the equation for red graph is given by

[tex]g(x) =a(x-0)^{2} + 2[/tex]

[tex]g(x) = 1x^{2} +2[/tex]                 (because a = 1)

⇒ [tex]g(x) = x^{2} +2[/tex]

Hence, option c is correct.

Answer:

8 boxes of tissues

5 bags of cough drops

Step-by-step explanation:

You need to write a system of equations.

x = number of tissue boxes

y = number of cough drop bags

x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.

So, your first equation is

x + y = 13

Then, you need to write the second equation.

(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]

That's a lot to read, so here's the equation simplified!

1.69x + 1.19y = 19.47

Now, you have two equations:

x + y = 13

1.69x + 1.19y = 19.47

I would solve with the substitution method.

the first equation can be changed to x = 13 - y by subtracting y from both sides.

Then, your two equations are:

x = 13 - y

1.69x + 1.19y = 19.47

Now, you can plug in that value of x into the second equation!

1.69(13 - y) + 1.19y = 19.47

21.97 - 1.69y + 1.19y = 19.47

subtract 21.97 from both sides

-1.69y + 1.19y = -2.5

Add the y values

-0.5y = -2.5

divide both sides by -0.5

so, y equals 5 bags of cough drops

now that you know what y equals, plug it back into your original equation to find x!

x + y = 13

plug in y

x + 5 = 13

x = 8

so, x = 8 boxes of tissues

Hope this helps! Let me know if you have any questions!

Answer:

Length of side QP = 5

Answer:y=7(2)^x

Step-by-step explanation:

The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.

Exponential functions are functions where the independent variable, x is in the exponent.

The general form of exponential function is,

f(x) = abˣ

The function passes through (0,7) and (9, 3584).

Substituting (0, 7),

7 = a b⁰

7 = a  (since b⁰ = 1)

So, a = 7

Function is f(x) = 7bˣ

Now Substituting (9, 3584),

3584 = 7 b⁹

b⁹ = 3584 / 7

b⁹ = 512

b⁹ = 2⁹

b = 2

So the function is f(x) = 7(2)ˣ

Hence the function is f(x) = 7(2)ˣ.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

From the right triangle 1:

Let the hypotenuse be a.

So, a²=1²+1²

⇒a=√2

From the right triangle 2:

Let the hypotenuse be b.

So, b²=(√2)²+1²

⇒b=√3

From the right triangle 3:

Let the hypotenuse be c.

So, c²=(√3)²+1²

⇒b=√4=2

From the right triangle 2:

The hypotenuse=x

So, x²=2²+1²

⇒x=√5

Therefore, the x value for the given partial spiral is √5 units.

The line AB.

Slope = (7 - 5) / (-2 - 3) = 2 / -5 = -2/5

The line CD.

Slope = (15 - 5) / (6 - 10) = 10 / -4 = -5/2

slope of AB x slope of CD.

= -2/5 x -5/2

= 1

This means,

The lines are on the same line.
