Rate of change of given points is 3/2.
Given that
The values of x and y,
x values are 2, 4, 6, 8 and
y values are 5, 8, 11, 14.
To find
Rate of change = ...?
So, according to the question
we have,
The values of x = 2, 4, 6, 8
The values of y = 5, 8, 11, 14.
We know that,
Rate of change = (change in y )/(change in x)
= [tex]\frac{8-5}{4-2}[/tex]
= [tex]\frac{3}{2}[/tex]
The difference of other points are same, so the rate of change of given coordinates is 3/2.
Rate of change = 3/2

Kendal bought x boxes of cookies to bring to a party. Each boxes contain 12 cookies. She decided to keep 2 boxes for herself. She brings 60 cookies to the party. What equation can be use to find the number of boxes, x kendal bought
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
Narek and his family are driving home from vacation and
plan on taking their time. They drive the same amount of
miles every day. After 4 days of driving, they are 400
miles from home. After 8 days of driving, they are 250
miles from home. Let x represent the number of days
Narek and his family are driving home from vacation and
y represent how far away from home (in miles) they are.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of days Narek and his family are driving home from vacation and y represent how far away from home (in miles) they are.
Narek and his family vacation can be represented by coordinate points (x, y) as (4, 400) and (8, 250). We can get an equation using this formula:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\Hence:\\\\y-400=\frac{250-400}{8-4}(x-4)\\\\y-400=-37.5(x-4)\\\\y-400=-37.5x +150\\\\y=-37.5x +550[/tex]
The x intercept is the value of x when y = 0:
0 = -37.5(x) + 550
37.5x = 550
x=14.7
The y intercept is the value of y when x = 0:
y = -37.5(0) + 550
y = 550
Therefore the x intercept is 14.7. Which means that when Narek and his family drive for 14.7 days, they are 0 miles from home.
Therefore the y intercept is zero. Which means that when Narek and his family drive for 0 days, they are 550 miles from home.
Comparing the above equation with the equation of a straight line y = mx + b, where m is the slope and b the y intercept, we can get that the slope (m) is -37.5.
The slope is -37.5. This means that for every one day, they have 37.5 miles less to drive to get home.

An angle pair that is on the exterior of two lines but on opposite sides of the transversal.
PLEASE HELP ME AS SOON AS POSSIBLE ITS AN EMERGENCY Caleb draws 2 triangles and claims that the triangles are congruent. For the case that his claim is true, determine whether each statement below must be true.Select yes or no for each statement.
Answer: 1 and 3
I just took the test
Calculate the size of angle a when two known angles are 80 degrees and 30 degrees
70° is the angle.
every triangle has a total of 180°, therefore 180-80-30=70°
Angle size calculation refers to the use of geometrical laws and invariants to find out how many degrees an angle is. Therefore, it is different from angle size measurement, which includes the use of a protractor or other tools to come up with the result. Calculating an angle's size demands knowledge of complementary, supplementary, and adjacent angles, as well as the properties of geometric shapes.
Subtract the given supplementary angle (its value in degrees) from 180 to calculate the size of the angle in question. Supplementary angles, or straight angles, are those whose sum adds up to 180 degrees.
Repeat the process, this time subtracting the given angle from 90, to calculate the size of an unknown complementary angle. Complementary angles, or right angles, are those summing up to 90 degrees.

Use the number line to add −3/5 and 1 1/4.
Answer:
13/20
Step-by-step explanation:
You can write 1 1/4 as 5/4. Any fraction that has the same number in the numerator and the denominator equals 1. For example 4/4 = 1, 20/20 =1, 5/5 = 1 and so on.
I can rewrite 1 1/4 as 4/4 + 1/4 = 5/4
Now we want to add -3/5 and 5/4. We need a common denominator because the pieces of the fractions are not equal. The smallest number that 5 and 4 will go into is 20. Si U an going to write the two fractions with 20 as the denominator.
-3/5 = -12/20 I multiplied the top and the bottom of -3/5 with 4.
5/4 = 25/20 I multiplied the top and the bottom of 5/4 by 5
-12/20 + 25/20 = 13/20

Answer:
Adrian lives closer to the school by A. 1,250 meters.
Step-by-step explanation:
1 kilometer = 1,000 meters
So, if Kevin's home is 2 kilometers from the school, then it is also 2,000 meters away, since 1,000 x 2 = 2,000.
Adrian lives 750 meters, or 0.75 kilometers away from school.
2,000 - 750 = 1,250.
Therefore, Adrian lives closer to the school by A. 1,250 meters.

Answer:
[tex]x=31.8[/tex]
Step-by-step explanation:
Use the trigonometry ratios to find x. The cosine ratio is used when you are given the side adjacent to the angle and the hypotenuse (the hypotenuse is never considered the adjacent side):
[tex]cosineX=\frac{adjacent}{hypotenuse}[/tex]
Insert the values:
[tex]cos51=\frac{20}{x}[/tex]
Solve for x. Multiply both sides by x:
[tex]x(cos51)=x(\frac{20}{x})\\\\x*cos51=20[/tex]
Isolate the variable. Divide both sides by cos51:
[tex]\frac{x*cos51}{cos51} =\frac{20}{cos51} \\\\x=\frac{20}{cos51} \\\\[/tex]
Insert the value into a calculator to be simplified:
[tex]x=31.78[/tex]

in a household, a business is run for an average of 6 hours per day. the total power consumed by a computer and its printer is 230 watts. in addition, a 100-w light bulb runs during the same 6 hours. if their utility charges 11.75 cents per kwh, how much do the owners pay every 30-days?
The amount that the owners will pay every 30 days is $6.98.
The total electricity consumed per hour equals power consumed by computers and printers plus light.The total electricity consumed per hour is 230 watts plus 100 watts.The total electricity consumed per hour equals 330 watts per hour.The total monthly electricity consumption equals total monthly electricity consumption * 6 hours * 30 daysThe total electricity consumed per month equals 330 watts x 6 hours x 30 days.The total electricity consumed is 59,400 wattsThe total electricity consumed is 59.4 kwhThe monthly electric bill equals the total electricity consumed multiplied by the utility charges per kwh.The monthly electric bill equals 59.4 kwh x 11.75 cents.The monthly electric bill is 697.95 cents.The monthly electric bill is $6.98.Therefore, the amount that the owners will pay every 30 days is $6.98.To learn more about power, visit :

sally has 2 cats and each cat eats 1/4 of a tin of cat food each day. sally buys 7 tins of cat food. for how many days will the cat food feed her two cats?
Division is one of the four fundamental arithmetic operations. The number of days this cat food will last is 14 days.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that each cat eats 1/4 of a tin of cat food each day. Therefore, the amount of food that two cats will eat in a day is,
= 2 × 1/4 of a tin of cat food each day
= 1/2 of a tin of cat food each day
Further, it is given that Sally buys 7 tins of cat food. Therefore, the number of days this cat food will last is,
= Total cat food / Cat food needed in a day
= 7tin of cat food / 1/2 of a tin of cat food each day
= 14 days
Hence, the number of days this cat food will last is 14 days.
