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

The Bulldogs gained 11 1/2 yards

Step-by-step explanation:

its sad that they could lose so much ground on a sack. their qb must suck

15 1/2 ---> 15.5

3 1/4 ---> 3.25

-7 1/4 ---> -7.25

15.5+3.25= 18.75

18.75 -7.25= 11.5 ---> 11 1/2 yards

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.

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:

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

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:

[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]

Simplifing by 6:

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

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.
