Answer:

y = -3x-1

Step-by-step explanation:

Point-slope equation of a line

y-y1=m(x-x1)

(x1,y1) are coordinates of a point in the line = (-3,8)

m is the slope of the line = -3

Fill in what you know and move constants to get y by itself (y=mx + b ... slope-intercept equation)

y-8=-3(x+3)

y-8=-3x-9

+8 +8

y = -3x-1

Answer:

$37.00 9 $49.00

Step-by-step explanation:

The solution of the formula for p is  p = I/ rt which is divided by the principle p times r. which is the correct answer would be an option (C)

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

Given that the formula as:

⇒ I = prt

where I = Interest, P = principal,

R = rate and T = time is used to calculate the amount of simple interest earned.

⇒ I = prt

After getting P on one side, you must divide rt to get the letter p by itself.

⇒ I = prt

⇒ p = I/ rt

Hence, the correct answer would be option (C)

Answer:

The fabric left over will be [tex]2\frac{5}{6}[/tex]

Step-by-step explanation:

Total fabric bought= [tex]8\frac{3}{4} \ yd[/tex]

Fabric used for skirt = [tex]1\frac{7}{8} \ yd[/tex]

Fabric used for pants = [tex]2\frac{3}{8} \ yd[/tex]

Fabric used for vest = [tex]1\frac{2}{3} \ yd[/tex]

Total fabric used = Fabric used for skirt+Fabric used for pants+Fabric used for vest

Total fabric used=[tex]1\frac{7}{8}+2\frac{3}{8}+1\frac{2}{3}[/tex]

[tex]=\frac{15}{8}+\frac{19}{8}+\frac{5}{3}\\=\frac{15*3+19*3+5*8}{24}\\=\frac{45+57+40}{24}\\=\frac{142}{24} \\=\frac{71}{12}[/tex]

So, Total fabric used = [tex]\frac{71}{12}[/tex]

Total Fabric left= Total fabric bought-Total fabric used

Total Fabric left=[tex]8\frac{3}{4}-\frac{71}{12}[/tex]

[tex]=\frac{35}{4}-\frac{71}{12}\\=\frac{35*3-71}{12} \\=\frac{105-71}{12}\\=\frac{34}{12}\\=\frac{17}{6}\\=2\frac{5}{6}[/tex]

So, the fabric left over will be [tex]2\frac{5}{6}[/tex]

Answer:

the number of men be 56

And, the number of women be 74

Step-by-step explanation:

The computation of the number of each genders attended the conference is shown below;

Let us assume the number of men be x

And, the number of women be y

Now the equations would be

x + y = 130 .............. (1)

And,

y = 18 + x ................ (2)

Now put the y value in the equation 1

x + 18 + x = 130

2x = 130 - 18

2x = 112

x = 56

Now the y is

= 18 + 56

= 74

So, the number of men be 56

And, the number of women be 74

Answer:

32.14 an hour

Step-by-step explanation:

Answer:

32.142857 miles per hour

Step-by-step explanation:

This is the answer because:

This is a fraction equal to

225 miles ÷ 7 hours

We want a unit rate where  1 is in the denominator,  so we divide top and bottom by 7 .

225/7 = 225/7 and 7/7 =  32.142857/1

Therefore, the answer is  32.142857 miles per hour.

Hope this helps!

Answer:

y = 3

m = 0

b = (0, 3)

Step-by-step explanation:

To put it in slope intercept form, divide each side by 2:

2y = 6

y = 3

So, y = 3 is the equation in slope intercept form.

The slope is 0, since there is no x value in the equation.

The y-intercept is (0, 3) since the equation is just y = 3.

Answer:

5.10 people

Step-by-step explanation:

Calculation to Find the standard deviation for the number of people with the genetic mutation

Using this formula

Standard deviation = √ ( n * p * q)

Where,

n = 400

p = .07

q = 100%-7% = 93% or .93

Let plug in the formula

Standard deviation =√400*07*.93

Standard deviation =√26.04

Standard deviation = 5.10 people

Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.

Answer:

My guess would be D.

Step-by-step explanation:

We can eliminate A and B right away considering the Slope of the first equation is already -1/3 and we need the slope to be opposite to be perpendicular. So right then It is either C or D. and with C It doesn't seem like the line intersecting the line above would be parallel so my guess is D.

The fraction of the shape which is shaded in simplest form is 1/3.

The square in the diagram provided has a total of 12 boxes .

The number of shaded part is 4

To calculate the shaded fraction of the shape we have to use the formula:

Number of shaded part/ Total number of boxes present.

= 4/12

We can divide the numerator and denominator by 4 to get the simplest form.

= 1/3

The fraction of the shape which is shaded in simplest form is therefore

= 1/3.

Answer:

y=7/6x

Step-by-step explanation:

When given an equation and asked to find the equation of a perpendicular line that intersects it, you know that the slope is the slope of the equation is the negative recipricoal of the given equation. i.e. y=2x+2 and y=-1/2x+2. The y-intercept does not matter.

Answer:

The answer is B.

Step-by-step explanation:

Please refer to the attachment (ignore the horrible drawing, thank you).

Let the distance from P to T be red. The length of the red distance is x radians.

T’ is π-x. Thus, it is the red distance subtracted from the purple distance.

So, T’ is the reflection of T across the y-axis.

Therefore, we can simply multiply the x-coordinate of T to get T’.

T is (3/5, 4/5)

Then T’ must be (-3/5, 4/5).

Hence, our answer is B.

  A  The number of miles driven will always be greater than or equal to zero and cannot be less than zero.

Step-by-step explanation:

The domain of a function such as this is the set of values that realistically may be given as input to the function. We know of no way to ride a motorcycle a negative number of miles, so the domain must be non-negative numbers.
