Answer:
y = 1/3x - 2:
y - intercept: - 2x - intercept: 6y = 12 - 6x:
y - intercept: 12x - intercept: 2y = 3x - 7:
y - intercept: -7x - intercept: 7/3Step-by-step explanation:
Hello!
Slope Intercept FormThe slope-intercept form of a line is [tex]y = mx + b[/tex]
y = output, ordinatem = slopex = input, abscissab = y-intercepty = 1/3x - 2The y-intercept is the "b" value of the line, given as -2.
To find the x-intercept, we simply replace the y-value with 0:
0 = 1/3x - 22 = 1/3x6 = xy - intercept: - 2
x - intercept: 6
____________________________________________________
y = 12 - 6x
You can rearrange the equation, y = -6x + 12, to find the y-intercept: 12.
Solving for the x-intercept (remember, replace y with 0):
0 = -6x + 12-12 = -6x2 = xy - intercept: 12
x - intercept: 2
____________________________________________________
y = 3x - 7Simply take the "b" value, -7, to find the y-intercept of -7.
Solve for the x-intercept:
0 = 3x - 77 = 3xx = 7/3y - intercept: -7
x - intercept: 7/3
Additional Note:
You can also solve for the y-intercept by replacing x with 0. This method can be used for any interests, just plug in the opposite variable from what you are solving for with 0.
The proof is that the x-intercept is the value when the y = 0, the x-axis. You can plug in 0 for y to solve for x. Similarly, when solving for the y-intercept, you plug 0 for x as the y-axis is at x = 0.

If the length of a rectangle is 6 more than twice the width and the total perimeter is 84cm, what is the rectangle's length?
Step-by-step explanation:
length = 2×width + 6
84 = 2×length + 2×width
now using the first in the second equation :
84 = 2×(2×width + 6) + 2×width = 4×width + 12 + 2×width
84 = 6×width + 12
72 = 6×width
width = 12 cm
length = 2×width + 6 = 2×12 + 6 = 24 + 6 = 30 cm
Find the correct missing value: y⁹ (x^²y = ³ ) ⁰ 12 X =
Answer:
-3
Step-by-step explanation:
Given equation:
[tex]\implies (x^4y^{-3})^n=\dfrac{y^9}{x^{12}}[/tex]
[tex]\textsf{Apply exponent rule} \quad \dfrac{1}{a^n}=a^{-n}:[/tex]
[tex]\implies (x^4y^{-3})^n=x^{-12}y^9[/tex]
Rewrite -12 as (4 × -3) and 9 as (-3 × -3):
[tex]\implies (x^4y^{-3})^n=x^{(4 \times -3)}y^{(-3 \times -3)}[/tex]
[tex]\textsf{Apply exponent rule} \quad a^{bc}=(a^b)^c[/tex]:
[tex]\implies (x^4y^{-3})^n=(x^4)^{-3}(y^{-3})^{-3}[/tex]
[tex]\textsf{Apply exponent rule} \quad a^c b^c=(ab)^c[/tex]
[tex]\implies (x^4y^{-3})^n=(x^4y^{-3})^{-3}[/tex]
Therefore, the missing value is -3

There are square tiles arranged in a pattern. the pattern has rows that are 5 tiles wide and an unknown number of rows. if you take these tiles and add one additional tile, you can create a pattern that has rows that are 3 tiles wide, with 3 more total rows than the original pattern. how many are in the original pattern?
An equation is formed of two equal expressions. The number of rows in the original pattern will be 4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of rows be represented by x. Now, the pattern has rows that are 5 tiles wide and an unknown number of rows. if you take these tiles and add one additional tile, you can create a pattern that has rows that are 3 tiles wide, with 3 more total rows than the original pattern. Therefore, we can write,
(Number of Tiles before) + 1 tile = (Number of Tiles afterward)
5x + 1 = 3(x+3)
5x + 1 = 3x + 9
5x - 3x = 9 - 1
2x = 8
x = 4
Hence, the number of rows in the original pattern will be 4.

a rectangle has an area of 7.5m2. one of the sides is 0.3m in length. what is the perimeter of the rectangle?
Step-by-step explanation:
the area of a rectangular is
length × width
we know the area and one side, let's say it's the width (it does not matter, as multiplication are commutative, and a×b = b×a).
so,
7.5 = length × 0.3
length = 7.5 / 0.3 = 25 m
the perimeter of a rectangle is
2×length + 2×width = 2×25 + 2×0.3 = 50 + 0.6 = 50.6 m

The bases of the prism below are right triangles. If the prism's height measures 8 units and its volume is 60 units³, solve for x.
Answer:
3
Step-by-step explanation:
Volume of prism = 0.5 times height times length times width
60 = (0.5)(8)(5)(x)
120 = 8(5)(x)
120 = 40x
x = 3
Let me know if its right
Length of another side of base x = 3 unit
What is prism?A prism has a solid shape consisting of two identical ends (such as triangle, square, rectangle, etc.), flat faces or surfaces and uniform cross-section across its length. The cross-section looks like a triangle hence called triangular prism. The shape of the prism does not have any curve. Therefore, a prism can have square, rectangular, pentagonal and other polygon shapes but not the circular shape.
Height of the prism = 8units
Length of one side of base = 5 units
Length of another side of Base = x
Base is a right angle
Base Area = 5x/2
Volume of prism = 60 unit³
Volume of Prism = Base Area × Height
60 = (5x/2) × 8
60/8 = 5x/2
x = 120/40
x = 3 unit.
Hence, x = 3 unit which is length of another side of base.

Answer:
[tex]5^{10} \cdot 5^{-7} = 5^3[/tex]
[tex]\frac{5^{10}}{5^{-7}} = 5^{17}[/tex]
Step-by-step explanation:
You have two equations:
[tex]5^a \cdot 5^b = 5^3[/tex]
[tex]\frac{5^a}{5^b} = 5^{17}[/tex]
But since
[tex]x^a \cdot x^b = x^{a+b}[/tex]
you only need to solve a+b = 3 and a-b=17
Rewrite the second as a = 17+b and plug it into the first:
17+b + b = 3, then you find, 2b = -14, so b = -7.
Then a=3-b, so a = 10.

Replacing that, we will get:
[tex](500*10^{-9}) - (7*10^{-9}}) = 493*10^{-9}[/tex]

A group of 40 students from your school is part of the audience for a TV game show. The total number of people in the audience is 120 . What is the theoretical probability of 5 students from your school being selected as contestants out of 10 possible contestant spots?
Using the hypergeometric distribution, it is found that there is a 0.1363 = 13.63% theoretical probability of 5 students from your school being selected as contestants out of 10 possible contestant spots.
What is the hypergeometric distribution formula?The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.The values of the parameters are given as follows:
N = 130, k = 40, n = 10.
The theoretical probability of 5 students from your school being selected is P(X = 5), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 5) = h(5,120,10,40) = \frac{C_{40,5}C_{80,5}}{C_{120,10}} = 0.1363[/tex]
