Activity 1: rewrite me!
1. write the equation 2x+3y=12into y=mx+b
Solution
2x+3y=12
2x + (____) + 3y = 12+(-2x)
(____)3y=(-2x+12)(____)
y= - ⅔x +4
Given:
Simplified as y= mx+ b
2.write the linear equation y= -2x -1 into Ax + By = C.
solution
y = -2x-1
y +(____) = - 2x + (___) - 1
2x + y = -1
Given:
Questions:
1. how did you write the linear equation y = mx + b to the form Ax + By = C?
2. how did you write Ax + By = C?
3. what mathematical concepts or principles did you apply to write each linear equation to standard form?
to y=mx+b form?

1) The equation 2y + 3x = 12 in the y = mx + b form is [tex]y = -\frac{2}{3} x + 4[/tex]
2) The linear equation y = -2x - 1 in the Ax + By = C form is 2x + y = -1
The point-slope form of the equation of a line is y = mx + b
where m represents the slope
b represents the y-intercept
The given equation is:
2x + 3y = 12 (Given)
Subtract 2x from both sides
2x + (-2x) + 3y = 12 + (-2x)
3y = 12 - 2x (Equality property of addition)
3y = -2x + 12 (Commutative property of addition)
Divide both sides by 3
[tex]\frac{3y}{3} = -\frac{2}{3} x + \frac{12}{3} \\\\y = -\frac{2}{3} x + 4[/tex](Equality property of division)
2) Write the linear y = -2x - 1 into Ax + By = C
y = -2x - 1 (Given)
Add 2x to both sides
y + 2x = -2x + 2x - 1 (Equality property of addition)
y + 2x = -1
2x + y = -1 (Commutative property of addition)

For a science project hailey puts a cylindrical can out to collect rain water the can was 11 inches tall and diamamter of 8 inches if it rained exactly 20 cubic inches a day how many days
Answers
Answer:
27.7 days
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 8/2
(22/7) x (4^2) x 11 == 553.14 in^3
if it rains 20 cm^3 per day, the can would fill in : volume of can / amount of rain = 553.14/20 = 27.7 days

Answers
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate

Answers
Answer:1/343
Step-by-step explanation:
you can use the exponent rule so you would be left with (1/7)^9-6 which would simplify to (1/7)^3. The if you not using a calulater, you can take 1/7 and individually cube the numbers to find the final answer. So 1^3/7^3. This would simplify to 1/7^3. 7^3 is 343. This leaves you with the final answer.
