What is a slope?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.

what is the equation of the line perpendicular to y=1/2x-3 going through the point P(10,5)?
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:
[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]

James buys 8 tomatoes that have a combined weight of 4.5 pounds. The scale measures to the nearest hundredth of a pound. What is the most precise value of the average weight of the tomatoes that James purchases, given the level of accuracy of the scale?
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

At a gas station, the price of gas is $2.40 a gallon. Write an equation using slope-intercept form that relates the total cost, C, to the price per gallon of gas, g
Answer:
C= 2.40g+0
Step-by-step explanation:
The total cost is reliant on how many gallons of gas the customer buys. If the person bought 8 gallons, you'd plug 8 in for g. 8 times 2.40 = $19.20

The amount of water a washing machine uses varies directly with the number of loads it washes. If a washing machine uses 28 gallons for 2 loads of laundry, how many gallons would it use for 10 loads of laundry?
140 gallons of water would it use for 10 loads of laundry.
What is meant by the term direct proportional?A direct proportion is an arithmetical comparison of two numbers whose ratio is comparable to a constant value. According to the proportion definition, two ratios are in proportion when they are equivalent. The proportions are indicated by the symbol "∝".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.

A box contains 4 red marbles, 7 white marbles, and 8 blue marbles. If a marble is randomly selected from the box, what is the probability that it is white? Express your answer as a fraction or a decimal number rounded to three decimal places, if necessary.
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
−5/6e−2/3e=−24 please help aa (also the slash is fraction)
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
