================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (8-6)/(2-5)
m = (2)/(-3)
m = -2/3
As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.
The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.

This is a geometric sequence of the form [tex]F=Ir^t\text{ where I=initial value, r=common ratio, and t=number of terms or time. Notice each term is 1/4 of the preceding term. This is the common ratio. So your equation is }f(x)=40\left(\frac{1}{4}\right)^x[/tex]
A factory produced 4000 light bulbs in one day. A sample of 100 bulbs was randomly selected and tested. The tests revealed that 7 of the 100 light bulbs were defective. At this rate, how many light bulbs would be defective out of the 4000 produced?

Stephen purchased a guitar, which was originally priced at $80 but discounted at 25%. He also had to pay 5% sales tax. What amount did Stephen pay to purchase the guitar?
Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.

There were some pizzas in the library. 13 pizzas were eaten by zombies. There are now 20 pizzas in the library. Which equation can be used to find p, the number of pizzas that were in the library?
Answer:
p - 13 = 20
Step-by-step explanation:
p - 13 = 20
add 13 on both sides
p = 33
there were 33 pizzas in the library.
Answer:
p=13+20? or addition

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
Answer:
We can make the paint amount equal by making sure the parameters have the same unit
Step-by-step explanation:
Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?
To solve the above question, we have the conversion rate:
We can make the paint amount equal by making sure the parameters have the same unit
Hence:
1 gallon (gal) = 3.785411784 kilogram (kg).
Billy had 5 gallons of paint.
1 gallon (gal) = 3.785411784 kilogram (kg).
5 gallons of paint = x
Cross Multiply
x = 5 × 3.785411784 kg
18.92705892 kilograms of paint
Approximately 18.93 Kilograms of paint
Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

m - 6 = 10 and i need work plzzz
Answer:
m=16
Step-by-step explanation:
m=10+6
m=16
Answer:
Add the 6 to the other side, this cancels out the six.
Step-by-step explanation:
m - 6 = 10
+6 | +6
m = 16
\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} −x+4y=−9 y=−2x+6 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation

Please help!!!! Maths!!!!!
Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3

He math team does practice drills that each last hour. In February the team did practice drills for a total of 24 hours. How many practice drills did the math team do in feburary
Answer: 24 drills
Step-by-step explanation:
The math team in question does math drills that last for an hour each time.
In February, a total of 24 hours were used to practice drills.
If the team takes an hour to do one drill, the drills that will be done in 24 hours are:
= Number of hours / Drills per hour
= 24 / 1
= 24 drills

Brielle's piggy bank has all nickels and dimes. The total value of the money in her piggy bank is $7.80.
If Brielle has 66 nickels, write and solve a linear equation to find the number of dimes she has. In standard form
Answer:
66 nickels = 66 x $0.5 = $3.30
$7.80 - $3.30 = $4.50
$4.50 / $0.10 = 45
Brielle has 45 dimes.
Answer:
She has 156 nickles in $7.80
