Answer:

Step-by-step explanation:

Answer:

x = 1

y = -2

Step-by-step explanation:

adding both quation we get

3x -2y + x + 2y =7 + -3

4x = 4

x = 1

substituting this equation in the earlier equation we get

3 * 1 -2y = 7

3 - 2y = 7

-2y = 4

y = -2

The amount of time it would will it take him to achieve his goal is B. $5,136; approximately 24 months.

This refers to the emergency funds that are set aside for situations that were not initially budgeted for.

Hence, because Sammy makes about $2,362/month

Rent, car insurance $1,292

Basic groceries, telephone $420

Snack items $260

Annual Savings $130

Annual emergency savings $210

5 years of vacation savings $50

Total= $2,362

Using Sammy's method of putting these budgets into separate checking accounts, the amount which Sammy needs to save to have x3 of his living expenses and the length of time it would take is $5,136; approximately 24 months.

Answer:

[tex]q = 34[/tex] when [tex]p = 2[/tex].

Step-by-step explanation:

Variables [tex]p[/tex] and [tex]q[/tex] ([tex]p \ne 0[/tex], [tex]q \ne 0[/tex]) are inversely proportional to one another if one variable- for example, [tex]p[/tex]- is proportional to the reciprocoal of the other variable- [tex](1/q)[/tex].

In other words, if [tex]p[/tex] and [tex]q[/tex] ([tex]p \ne 0[/tex], [tex]q \ne 0[/tex]) are inversely proportional to one another, there would exist a constant [tex]k[/tex] ([tex]k \ne 0[/tex]) such that:

[tex]\displaystyle p = k\times \left(\frac{1}{q}\right)[/tex].

The value of [tex]k[/tex] is constant and is independent of [tex]p[/tex] and [tex]q[/tex]. Given that [tex]p = 17[/tex] when [tex]q = 4[/tex], rearrange the equation above to find the value of [tex]k\![/tex]:

[tex]k = p\, q = 68[/tex].

Rewrite the equation again to find [tex]q[/tex] in terms of [tex]k[/tex] (which doesn't change) and [tex]p[/tex] (which might change):

[tex]\begin{aligned}q &= \frac{k}{p}\end{aligned}[/tex].

Since [tex]k = 68[/tex], given that [tex]p = 2[/tex], the value of [tex]q[/tex] would be:

[tex]\begin{aligned}q &= \frac{k}{p} \\ &= \frac{68}{2} = 34\end{aligned}[/tex].

Answer:

34 inches.

Step-by-step explanation:

In order to ger perimeter you need to find the value of all sides. We know one side is 9 inches. To find the other side length you divide the area by the side length (72/9=8). This is because the formula for area is length times width. To find permiter you add all the side lengths together. A rectangle has 4 sides, so you would do 9+9+8+8

Answer:

82.799...°

Step-by-step explanation:

First, we have to identify how many votes equals 1°

Therfore we divide 4700 by 360° because there are a total of 4700 votes and there are 360° in a circle.

(4700/360) = 13.055...

1° = approximately 13 votes

Secondly, let's look at how many votes Watkins received.

1081 votes

Lastly, since 1° equals 13.055... votes,

then if we divide the number of total votes Watkins got by 13.055 we will find the value of the central angle for the Watkins slice.

1081 ÷ 13.055... = 82.7999..

Answer:

[tex]\sf \dfrac{7}{17}[/tex]

Step-by-step explanation:

Given information:

⇒ total number of crayons = 6 + 7 + 4 = 17

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

[tex]\implies \sf P(red\:crayon) =\dfrac{\textsf{Number of red crayons}}{\textsf{Total number of crayons}}=\dfrac{6}{17}[/tex]

If the red crayon is put back in the bag, the drawing of the red crayon prior to drawing the blue crayon will not affect the probability of drawing a blue crayon.

[tex]\implies \sf P(blue\:crayon)=\dfrac{\textsf{Number of blue crayons}}{\textsf{Total number of crayons}}=\dfrac{7}{17}[/tex]

Answer:

y = 1/4x + 2

Step-by-step explanation:

We do y = mx + b

slope = rise over run = 1/4

Y-intercept = 2

Equation is y = 1/4x + 2

Answer:

y = -0.25x + 2

Step-by-step explanation:

When x=0, y = 2

When y=0, x = 8

X = 0 – 4 = -4

Y = 2 – 1 = 1

[tex]Slope\:(m)=\frac{y}{x} =\frac{1}{-4} =-0.25[/tex]

Answer:

720

Step-by-step explanation:

16=2^4

30=5*3*2

36=(2^2)*(3^2)

so

(2^4)*5*(3^2)=720

Answer:

The error is founded in the slope, specifically in the run.

When seen a negative slope, that only applies to the rise but not the run.

Instead, the student should run 1(not 2) units to the right.

The slope had not mentioned any 2 in the run.

So it would sound like down 3, over 1, starting from 2.

The y intercept at 2 is correct. This is the location (0,2)

The slope is -3 or -3/1, meaning that we move down 3 and to the right 1 unit. Doing so has us go from (0,2) to (1,-1). Plot these two points together on the same xy grid and draw a straight line through the two points.

See below.

Using linear function concepts, it is found that the change in the breaking weight of the pennies was of -6 units of weight.

A linear function is modeled by:

y = mx + b

In which:

In this problem, the function is:

y = -6x + 136.

The slope is of m = -6, hence the change in the breaking weight of the pennies was of -6 units of weight.
