Given the equation 9x - 3y - 27 in standard form. Show how you would
convert the equation into slope-intercept form - y = mx + b. You must
show your work to receive full credit. (3 points)
A standard form equation is when it is set up
Ax + By = C.
6x + 2y = 4
A slope-intercept form equation is when it is set up y=mx+b.
Y = - 3x + 2
In order to go from one form to another, all you have to do is change the order of the given numbers. First you want to move the Ax to the opposite side of the equation, by either adding or subtracting it. At this point your equation will be set up By = -Ax + C. Then you want to divide the B from the By and the rest of the equation. Therefore you will have y = - Ax/B + C/B. This is the same thing as the slope-intercept form, just a few of the letters are different.
Example 1:
Change from standard to slope form
8x + 4y = 16
8x + 4y = 16 first subtract 8x
4y = -8x + 16 then divide all by 4
y = -2x + 4 slope form
Example 2:
6x + 3y = 21
6x + 3y = 21 subtract 6x
3y = -6x + 21 then divide all by 3
y = -2x + 7 slope form

Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 4 as the denominator :
28 28 • 4
28 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (28 • 4) x - 112
———————————— = ———————

When a fraction equals zero
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-112
————— • 4 = 0 • 4
4
Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-112 = 0
Solving a Single Variable Equation:
4.2 Solve : x-112 = 0
Add 112 to both sides of the equation :
x = 112
One solution was found :
x = 112

Given the following two points write the equation in slope intercept form: (0, -5) and (4, 3)
Answer:
[tex]y=2x-5[/tex]
Step-by-step explanation:
Let's start by finding the slope using the two points given. Use the formula for slope below:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Identify your values:
[tex]x_1=0\\x_2=4\\y_1=-5\\y_2=3[/tex]
Substitute:
[tex]m=\frac{3-(-5)}{4-0}[/tex]
Combine terms:
[tex]m=\frac{8}{4}[/tex]
Simplify:
[tex]m=2[/tex]
_
Let's graph these two points. As seen on the graph attached, we can see that [tex]-5[/tex] is the y-intercept. With our slope and y-intercept, we have the information needed to formulate an equation in slope-intercept form:
[tex]y=mx+b[/tex]
Identify your values:
[tex]m=2[/tex]
[tex]b=-5[/tex]
Substitute:
[tex]y=2x-5[/tex]

which expressions are equal to 3/5 × 6
a. 3 × ( 6 ÷ 5 )
b. 3 ÷ (5 × 6 )
c. ( 3 × 6 ) ÷ 5
d. 3 × 6/5
Answer:
A & C & D
Step-by-step explanation:
A & C & D both show the commutative property of multiplication and therefore is the correct answer because 3/5(6) = 18/5 and 3(6/5) is also 18/5.
3 x (6÷5) is also 18/5
(3×6)÷5 is also 18/5
A farmer has 48 feet of fence with which to make a corral. If he arranges it into a rectangle that is twice as
long as it is wide, what are the dimensions?
The shorter side is ?
feet while the longer side is ?
feet.
Answer:
The shorter side is 8 feet
the longer side is 16 feet
Step-by-step explanation:
lets call the shorter side x.
let's call the longer side 2x (because it's twice as long as the shorter side)
you know that the perimeter is 48 feet.
the perimeter would be 2(short side) + 2(long side)
using this, you can make the following equation:
2(x) + 2(2x) = 48
open the parenthesis.
2x + 4x = 48
6x = 48
x = 8
2x = 16

A bird leaves its nest and travels 15 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
a. What is the distance of the entire trip?
miles
b. How long does the entire trip take?
_hours
_minutes and
_seconds
Answer:
A)
10 miles.
B)
0 hours, 40 minutes, and 0 seconds.
Step-by-step explanation:
Remember that distance is given by the formula:
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
We know that the bird leaves its nest and travels 15 miles per hour for x hours. So, let's substitute 15 for s and x for t:
[tex]d=15x[/tex]
On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
Since this is the return trip, the distance d remains the same. We know that the bird travels 3 miles per hour slower, so it's speed is 15-3 or 12 miles per hour.
However, after x hours, it still has 2 miles left until reaching the destination. So, we will subtract 2 from d. This gives us the equation:
[tex]d-2=12x[/tex]
We can solve this using substitution. Since we already know that d is 15x. Substitute:
[tex]15x-2=12x[/tex]
Solve for x. Subtract 12x from both sides:
[tex]3x-2=0[/tex]
Add 2 to both sides:
[tex]3x=2[/tex]
Divide both sides by 3:
[tex]x=2/3[/tex]
Therefore, the bird traveled for a total of 2/3 hours or 40 minutes.
And the distance the bird traveled is:
[tex]d=15x[/tex]
Substitute 2/3 for x to get:
[tex]d=15(2/3)=30/3=10\text{ miles}[/tex]

? to ?
The ratio of dollars to slices is 2 and the cost per slice is $2.
What is ratio?In mathematics, a ratio shows how many times one number contains another.
Given is that a large two-topping pizza from Tony's Pizzeria has 8 slices and costs $16.
The ratio of dollars to slices is given as - r = 16/8 = 2The ratio of dollars to slices is given as is also equal to cost per slice as - r = cost per slice = $2
Therefore, the ratio of dollars to slices is 2 and the cost per slice is $2.

The sum of the first three terms of a sequence is 6 and the fourth term is 16
Answer:
a₁ = -5, d = 7, a₂ = 2, a₃ = 9, a₄ = 16
equation of sequence: [tex]\boxed{\bold{a_n=7n-12}}[/tex]
Step-by-step explanation:
a₁ + a₂ + a₃ = 6
a₁ + a₁ + d + a₁ + 2d = 6
3a₁ + 3d = 6
a₁ + d= 2 ⇒ a₁ = 2 - d
a₄ = 16
a₁ + 3d = 16
2 - r + 3d = 16
2d = 14
d = 7
a₁ = 2-7 = -5
a₁ = -5, d = 7 ⇒ a₂ = -5+7 = 2, a₃ = 2+7 = 9, a₄ = 9+7 = 16
equation of arithmetic sequence:

(f + h)(x)
given f(x)= 3x-2x+4, g(x)= 8x-2, h(x)= 3x +2
Answer:
To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.
(f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]
= 3x + 2 + 4 – 5x
= 3x – 5x + 2 + 4
= –2x + 6
(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]
= (3x + 2)(4 – 5x)
= 12x + 8 – 15x2 – 10x
= –15x2 + 2x + 8
\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(
