Answer:

Y=1/3x-6

Step-by-step explanation:

Answer:

Subtract x from both sides.

-3y = -x + 18

Divide everything by -3.

y = -1/3 - 6

Answer:

Most precise value of the average weight is 0.56 pounds

Step-by-step explanation:

To get the precise value, we start by getting the average weight

That will be total weight/8

= 4.5 pounds/8 = 0.5625

we are told that the scale records to the nearest hundredth

So we need to express the obtained value in hundredths

That will be 0.56 pounds

140 gallons of water would it use for 10 loads of laundry.

For the given question;

The amount of water a washing machine uses varies directly with the number of loads it washes.

Let amount of water be 'w'.

The number of loads be 'l'

w ∝ l

w = kl

k = proportionality constant.

For, w =  28 gallons

l = 2 loads of laundry

Put in the equation;

28 = 2 k

k = 14

Now, when l = 10 loads of laundry, w = ?

w = 14 × 10

w = 140

Thus, 140 gallons of water would it use for 10 loads of laundry.

Answer:

4.6

Step-by-step explanation:

The distance run on day 3 is about 5.9 miles.

If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).

The data points given are:

(1,2.5), (2,4.2), (4.5,6), (6,7), (8,8.1), (10,11)

Note that the growth seems to be linear, therefore, find a linear equation for the data.

Use (1,2.5) and (2,4.2) to find the slope of the line:

m = (4.2-2.5)/(2-1)

m = 1.7

The equation of the line with slope m = 1.7 and passes through point (1, 2.5) is:

y - 2.5 = 1.7(x - 1)

y = 1.7x - 1.7 + 2.5

y = 1.7x + 0.8

Substitute x = 3 into the above equation:
y = 1.7(3) + 0.8

y = 5.9

Hence, the distance run on day 3 is about 5.9 miles.

Answer:

e = 16

Step-by-step explanation:

−5/6e−2/3e= −24

−e(5/6+2/3) = −24

-e((5+4)/6) = −24

-e(9/6) = -24

-e(3/2) = -24

-3/2e = -24

- e = -24/(3/2)

-e = -16

e = 16

Answer:

The probability of selecting a white marble is 0.368

Step-by-step explanation:

Given;

number of red marbles, R = 4

number of white marbles, W = 7

number of blue marbles, B = 8

Total number of marbles in the box = 4 + 7 + 8 = 19

The probability of selecting a white marble is given by;

P(W) = 7 / 19

       = 0.368

Therefore, the probability of selecting a white marble is 0.368

Answer:

y=-2x+25

Step-by-step explanation:

the slope has to be -2, becauze in perpendicular lines, the slopes are opposite.

put it into y-y1=m(x-x1) form, which is y-5=-2(x-10)

then get rid of the parenthesis by distribution, which gives you y-5=-2x+20 (-10x-2 gives a positive 20)

then isolate y and balance the equation.

y-5+5=-2x+20+5, which gives you

y=-2x+25

Answer:

Correct answer is C

Step-by-step explanation:

The Function is linear but is not a direct variation function

The function is linear but is not a direct variation function.

The correct option is C.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

As per the information provided:

The points are collinear (i.e. they lie on a straight line), which means that the function is linear. We can find the equation of the line using the two-point form:

(y - 18)/(x - 10) = (30 - 18)/(18 - 10)

Simplifying this equation gives:

y - 18 = 3/2(x - 10)

y - 18 = 1.5x - 15

y = 1.5x + 3

So the function is linear, but not a direct variation function, and has a slope of 1.5.

[tex]\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}=\frac{5}{6}[/tex]

Step-by-step explanation:

Fraction Division

The division of two fractions a/b and c/d is usually done by multiplying the first fraction by the reciprocal of the second fraction:

[tex]\displaystyle \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\cdot\frac{d}{c}[/tex]

We are required to divide:

[tex]\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}[/tex]

Applying the above rule:

[tex]\displaystyle \frac{\frac{3}{4}}{\frac{9}{10}}=\frac{3}{4}\cdot\frac{10}{9}=\frac{30}{36}[/tex]
