Answer:

Y = - 0.2X + 5

Step-by-step explanation:

Given that:

Distance between Leah's home and friend's house = 5 miles

Distance X:

After 5 minutes, she is 4 miles from home

After 15 minutes, she is 2 miles from home

Hence ;

Change in distance with time (slope) :

(2 - 4) / (15 - 5) = -2 / 10 = -0.2

Initial distance from home (intercept) = 5

Hence, using the linear equation model:

Y = mx + c

m = slope or gradient ; c = intercept

Y = - 0.2X + 5

Answer:

$4.68

Step-by-step explanation:

If the stereo is 15% of then you have to do 85% of 275

[tex].85*275= 233.75[/tex]

If the sales person only makes a 2% commission then we need to do 2% of 233.75

[tex].02*233.75=4.675[/tex]

Since money only goes to the hundredths place we need to round to the hundredths.

DEF HAVE TWICE THE LENGTH OF ABC

Answer:

[tex]x=\{\frac{3\pi}{4}, \frac{7\pi}{4}\}[/tex]

Step-by-step explanation:

For the tangent line to be horizontal, the derivative of the function at that point must be 0.

Thus, let’s first take the derivative of our function:

[tex]f ^\prime(x)=\frac{d}{dx}[\cos(x)-\sin(x)][/tex]

Differentiate:

[tex]f^\prime(x)=-\sin(x)-\cos(x)[/tex]

Now, let’s set our derivative equal to 0:

[tex]0=-\sin(x)-\cos(x)[/tex]

Let’s multiply everything by a negative:

[tex]0=\sin(x)+\cos(x)[/tex]

To solve for x, we can subtract sin(x) from both sides. This gives us:

[tex]\cos(x)=-\sin(x)[/tex]

Now, we can refer to the unit circle. First, remember that the only points for which cosine is equal to sine is at the π/4 points. That is, π/4, 3π/4, 5π/4 or 7π/4.

However, cosine is equal to negative sine. The only two quadrants for which cosine and sine are the same but also have opposite signs is QII and QIV.

Therefore, our answers are 3π/4 and 7π/4.

Let, number of roses, carnations and lilies are x, y and z respectively.

So,

x + y + z = 215    ....1 )

It is given that total cost is $410.00 :

3x + y + 2z = 410    ....2 )

Also, there are 15 more lilies than roses.

z = x + 15    ....3 )

Putting value of z in eq 1 and 2 , we get :

x + y + x + 15 = 215

2x + y = 200     ....4 )

3x + y + 2( x + 15 ) = 410

5x + y = 380     ....5 )

Solving equation 4 and 5, we get :

3x = 180

x = 60

z = 60 + 15 = 75

y = 215 - 60 - 75 = 80

Therefore, number of roses, carnations and lilies are 60, 80 and 75 respectively.

Hence, this is the required solution.

Answer:

The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].

Step-by-step explanation:

From Analytical Geometry we know that equation of the line in slope-intercept form is represented by:

[tex]y = m\cdot x + b[/tex] (Eq. 1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

If we know that [tex]m = 0[/tex] and [tex]b = -6[/tex], then the equation of the line is:

[tex]y = 0\cdot x +(-6)[/tex]

[tex]y = -6[/tex]

The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].

Answer:

well shiet

Step-by-step explanation:

y=5/3x+9 is the slope intercept form of the equation of line   20x-12y=-108

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given equation is 20x-12y=-108

We need to write this equation in the form of slope intercept form.

To do this we have to isolate the y term

-12y=-108-20x

Now divide both sides by 12 and multiply with minus.

y=9+20/12x

y=9+5/3x

y=5/3x+9 is the required equation.

Hence,  y=5/3x+9 is the slope intercept form of the equation of line   20x-12y=-108

Step-by-step explanation:

There are two solutions for h it is:

2h+7=4 and 2h+7=-4

Lets do 2h+7=4

2h=-3 (Move the 7 to the other side)

h=-3/2 (Answer)

Lets do 2h+7=-4

2h=-11 (Move the 7 to the other side)

h=-11/2 (Answer)

Answer:

h=-3/2, -11/2

Step-by-step explanation:

There are two solutions for h

2h+7=4 and 2h+7=-4

2h+7=4:

Move the 7 to the other side to eliminate the 7 on the left side: 2h=-3

divide: h=-3/2

h=-3/2

2h+7=-4:

Move the 7 to the other side to eliminate the 7 on the left side: 2h=-11

divide: h=-11/2

h=-11/2

Answer:

The amount is 440.71

Step-by-step explanation:

"The electric bill reflected a monthly fee of $42.00 as well as a kilowatt per hour charge of $0.0953 for electricity used. Which function determines the amount of electricity used based on the total bill cost? Group of answer choices"

Given data

monthly fee= $42

kilowatt per hour charge=$0.0953

let the number of hours be =x

let the expression be patterned after the model\

y=mx

here  y=42

m=0.0953

We want to find x, the amount of electricity used

42=0.0953x

divide both sides by 0.0953 we have

42/0.0953=x

x=440.71

Answer:

The figure is rotating clockwise

Step-by-step explanation:

Let us revise the cases of rotation

1. Rotation with positive direction (anti-clockwise)

- If the point (x, y) rotated about the origin by angle 90° anti-clockwise

∴ Its image is (-y, x)

- If the point (x, y) rotated about the origin by angle 180° anti-clockwise

∴ Its image is (-x, -y)

- If the point (x, y) rotated about the origin by angle 270° anti-clockwise

∴ Its image is (y, -x)

2. Rotation with negative direction (clockwise)

- If the point (x, y) rotated about the origin by angle 90° clockwise  (-90°)

∴ Its image is (y, -x)

- If the point (x, y) rotated about the origin by angle 180° clockwise  (-180°)

∴ Its image is (-x, -y)

- If the point (x, y) rotated about the origin by angle 270° clockwise  (-270°)

∴ Its image is (-y, x)

From the given

∵ The figure is rotating around the origin by d degrees

∵ d < 0, which means d is negative

→ According to rule 2 above

∴ The direction of rotation is clockwise

∴ The figure is rotating clockwise
