Answer:

3y+5

Step-by-step explanation:

You will have to distribute the negative to (y-2).

4y+3-y+2

3y+5

Answer:

(4y + 3) - (y -2)

(4y + 3) - y + 2

3y + 3 + 2

3y + 5

Answer:

m= -1/2, (0,5), (10,0)

Step-by-step explanation:

Let us write it in slope intercept form, y=mx +b where m is the slope:

2x+4y=20

4y= -2x+20

y= -1/2x+5

Therefore, the slope is -1/2

The y intercept can be found when we substitue 0 as x.

y= -1/2*0 +5

y=0+5

y=5

(0,5)

The x intercept can be found when we substitute 0 as y.

0=-1/2x+5

-5 =-1/2x

x= 10

(10, 0)

I hope this helped! :)

Answer: b

Step-by-step explanation:

X is defined for all numbers on the domain starting at x=0. It doesn’t show or mention a cutoff/equation in the picture so it’s safe to assume it continues forever

To find the domain from the graph, you have to focus only x-axis because domain is the set of x-value.

From the graph, we can see that domain starts at x = 0 and keeps going and going positive infinitely. That means the domain must be greater or equal to 0.

Here is an easier way to understand

[tex]\large \boxed{ \sf{left/start}} \Longrightarrow \large \boxed{ \sf{right/end}}[/tex]

[tex] \large \sf{left = 0} \\ \large \sf{right = + \infin}[/tex]

And if we combine both, we get

[tex]0 \leqslant x \leqslant + \infin[/tex]

But we don't usually write positive infinity, therefore we convert to

[tex]0 \leqslant x \longrightarrow x \geqslant 0 \\ x \geqslant 0[/tex]

[tex]x \geqslant 0[/tex]

Answer:

360

Step-by-step explanation:

I just done the quiz and got it right :) Choice C! Have a great day! Sub to my YT Channel plz

The permutation of 6 things taken 4 at a time is 360 So, option C is correct.

The different arrangements which can be made out of a given number of objects by taking out some or all at a time are called permutations.

The permutation of 6 things taken 4 at a time.

It is calculated as follows;

[tex]^6P_ 4[/tex] = 6!/(6-4)! =6!/2!

[tex]^6P_ 4[/tex] = (6×5×4×3×2×1) ÷ (2×1)

[tex]^6P_ 4[/tex] = 720/2  = 360

So, option C is correct.

Answer:

an exponential growth function to represent this situation is:

[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]

Step-by-step explanation:

We know that the exponential growth function is of the form

[tex]x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t[/tex]

where

In our case,

Given that

A social media website had 100,000 followers its first year. Thus,

The number of followers increased by 9% each year. Thus,

Thus, substituting r = 0.09 and x₀  = 100,000 in the growth function

[tex]x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t[/tex]

[tex]x\left(t\right)=100,000\times \left(1+0.09\right)^t\:[/tex]

[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]

Therefore, an exponential growth function to represent this situation is:

[tex]x\left(t\right)=100,000\times \left(1.09\right)^t\:[/tex]

Answer:

The width of the rectangular park is 40m.

Step-by-step explanation:

We are given that the area of a square has the same area as the rectangle (the fact that they're parks doesn't matter)

We are also given one length side of the square, and since squares have all equal sides, we know all the side lengths are 60m.

To find Area, we do L * W, so it would be 60 * 60 = 3600.

That means the area of the rectangle park is 3600m. One side of the rectangle is 90m, so the formula is L * W = A. So we plug in known values of the rectangle which would be 90 * W = 3600. To find W, we do 3600/90 which is 40.

Answer:

Kindly refer to below explanation.

Step-by-step explanation:

Given equation of line:

[tex]\dfrac{x}{a}cos\theta+ \dfrac{y}{b}sin\theta =1\\OR\\\dfrac{x}{a}cos\theta+ \dfrac{y}{b}sin\theta-1=0[/tex]

Given points are:

[tex](\sqrt{a^2-b^2},0), (-\sqrt{a^2-b^2},0)[/tex]

Formula for distance between a point and a line is:

If the point is [tex](m, n)[/tex] and equation of line is [tex]Ax+By+C = 0[/tex]

Then, perpendicular distance between line and points is:

[tex]Distance = \dfrac{|Am+Bn+C|}{\sqrt{A^2+B^2}}[/tex]

Here,

[tex]A = \dfrac{x}{a}cos\theta\\B = \dfrac{y}{b}sin\theta\\C = -1[/tex]

For the first point:

[tex]m = \sqrt{a^2-b^2}, n = 0[/tex]

By the above formula:

[tex]p[/tex] and [tex]p'[/tex] can be calculated as:

[tex]p\times p' =\\\Rightarrow \dfrac{|\dfrac{cos\theta}{a}\times \sqrt{a^2-b^2}+ 0 -1|}{\sqrt{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\times \dfrac{|-\dfrac{cos\theta}{a}\times \sqrt{a^2-b^2}+ 0 -1|}{\sqrt{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}\\\Rightarrow \dfrac{1-(\sqrt{a^2-b^2}\times \frac{cos\theta}{a})^2}{\dfrac{cos^2\theta}{a^2}+\dfrac{sin^2\theta}{b^2}}}[/tex]

Formula used:

[tex](x+y)(x-y) = x^2 - y^2[/tex]

[tex]\Rightarrow \dfrac{\dfrac{a^2-a^2cos^2\theta+b^2cos^2\theta}{a^2}}{\dfrac{b^2cos^2\theta+a^2sin^2\theta}{a^2b^2}}\\\Rightarrow b^2(\dfrac{a^2sin^2\theta+b^2cos^2\theta}{a^2sin^2\theta+b^2cos^2\theta})\\\Rightarrow b^2[/tex]

(Using the identity:

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

(Hence provded)

Answer:

y = 5x - 22

Step-by-step explanation:

In this question, we have to find the equation of the line.

We know that the slope is 5 and passes through (5, 3) on the graph.

We know that our equation must be in slope-intercept form: y = mx + b

To find our y-intercept, or "b", we would plug in our given information and solve for b.

Solve for b:

3 = 5(5) + b

3 = 25 + b

Subtract 25 from both sides.

-22 = b

This means that our y-intercept is -22. We can now make our equation with our new information:

y = 5x - 22

The equation of the line is y = 5x - 22

Answer:

12% decrease

Step-by-step explanation:

[(new value - old value) / old value] x 100

(22 - 25) / 25 = -3/25 = -0.12

-0.12 x 100 = -12%

when you have a negative it indicates a decrease rather than an increase
