What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of the line be f ( x ) = y
And , the equation is
f ( x ) = 4x + 12
So , y = 4x + 12
To find the x intercept of the line ,
Substitute the value of y = 0
So , 0 = 4x + 12
Subtracting 12 on both sides , we get
4x = -12
Divide by 4 on both sides , we get
x = -3
Therefore , the x-intercept is ( -3 , 0 )
Now , To find the y intercept of the line ,
Substitute the value of x = 0
So , y = 12
Therefore , the y-intercept is ( 0 , 12 )
Hence , The x-intercept is ( -3 , 0 ), and the y-intercept is ( 0 , 12 )

Liliana wants to start a seventh-grade computer club at Hamden Middle School. She surveyed 20 seventh-grade students at the town park. She asked each student how many hours they spend on their computers each week. She obtained the following results.
8, 15, 0, 11, 12, 13, 16, 13, 0, 4, 17, 14, 30, 13, 5, 12, 1, 13, 12, 21
What is the ratio of the total number of students who used their computers to the total number of students surveyed?
StartFraction 2 over 20 EndFraction or StartFraction 1 over 10 EndFraction
StartFraction 2 over 18 EndFraction or StartFraction 1 over 9 EndFraction
StartFraction 18 over 20 EndFraction or StartFraction 9 over 10 EndFraction
StartFraction 18 over 2 EndFraction or StartFraction 9 over 1 EndFraction
Answer:
Liliana surveyed 20 students that how many hours they spend on their computers each week.
The results are as follows
8, 15, 0, 11, 12, 13, 16, 13, 0, 4, 17, 14, 30, 13, 5, 12, 1, 13, 12, 21
In the above results 2 students did not use computers out of 20 students.
Therefore, The total number of students who used their computers = 20 - 2 = 18
So the ratio would be 18 : 20 or 9 : 10
Answer:
Ratio would be 9 : 10

6(4.5y – 12) = 9 can someone help me anwser this please
Answer: y=3
Step-by-step explanation: 6(4.5y−12)=9
Step 1: Simplify both sides of the equation.
6(4.5y−12)=9
(6)(4.5y)+(6)(−12)=9(Distribute)
27y+−72=9
27y−72=9
Step 2: Add 72 to both sides.
27y−72+72=9+72
27y=81
Step 3: Divide both sides by 27.
27y/27 =81/27

The ratio of oranges sold to bananas sold is 3 to 10. If a total of 30 bananas were sold,then how many oranges were sold ?
Answer:
9
Each value is 3 times the number on the ratio.
10 x 3 = 30.
So, the ratio for oranges would be 9 because:
3 x 3 = 9.
So, the answer is 9.

and then graphing this inequality. She determines the solution set of the inequality is (infinity, 1.25 right-brace.
Which best describes Amy’s solution?
-Amy is correct. The interval (negative infinity, 1.25 right-brace is the solution set for the inequality.
-Amy did not break the inequality into two related inequalities. Her solution set only relates to one inequality.
-Amy used the incorrect inequality symbol. The solution set should be [1.25, ∞).
-Amy used the wrong variable when writing the solution. The solution set should relate to y and not x.

Prove that triangle with sides' lengths x^2−1, 2x, x^2+1 is a right triangle.
Answer:
See below.
Step-by-step explanation:
The converse of the Pythagorean Theorem tells us that if the sum of the square of the two shorter lengths is equivalent to the square of the longest length, then the triangle is indeed a right triangle.
We have the side lengths (x²-1), (2x), and (x²+1).
We can see that our hypotenuse will be (x²+1), since it will always yield the largest value for x.
So, we can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Substitute (x²-1) and (2x) for a and b, and substitute (x²+1) for c:
[tex](x^2-1)^2+(2x)^2\stackrel{?}{=}(x^2+1)^2[/tex]
Square each expression:
[tex](x^4-2x^2+1)+(4x^2)\stackrel{?}{=}(x^4+2x^2+1)[/tex]
Combine like terms:
[tex]x^4+(-2x^2+4x^2)+1\stackrel{?}{=}(x^4+2x^2+1)[/tex]
Add:
[tex]x^4+2x^2+1\stackrel{\checkmark}{=}x^2+2x^2+1[/tex]
We can see that the resulting equations are equivalent, proving that the triangle is indeed a right triangle.
And we're done!

(a)The population of a city is increasing exponentially at a rate of 2% each year. The population now is 256 000. Calculate the population after 30 years. Give your answer correct to the nearest thousand.
(b) A bacteria population increases exponentially at a rate of r% each day. After 32 days, the population has increased by 309%. Find the value of r.
Sorry.. Good Luck with the answer tho!...
(a)The population of the city after 30 years will be 463708.566 as per exponential growth.
(b) The value of the exponential 'r' is 4.5%.
What is the exponential growth of a system?"Exponential growth is a process that increases quantity over time."
Here, f(x) = a(1 + r)ˣ
f(x) = exponential growth function
a = initial amount
r = growth rate
x = number of time intervals
(a)The population of the city is (A) = 256,000.
The rate of increase of population per year is (r) = 2% = 0.02.
Time period (n) = 30 years.
Therefore, the population after 30 years
= A(1 + r)ⁿ
= 256000(1 + 0.02)³⁰
= 463708.566
(b) Let, the total bacteria is x.
The rate of increase of bacteria per day is = r%
Time period (n) = 32 days.
Total increased in bacteria in 32 days = 309%.
After 32 days, the total number of bacteria is
= x + (x × 309/100)]
= x + 3.09x
= 4.09x
Therefore,
4.09x = [tex]x(1 + r)^{t}[/tex]
⇒ [tex](1 + r)^{32}[/tex] = 4.09
⇒ (1 + r ) = 1.045
⇒ r = 0.045
⇒ r = 4.5%

what is the last term of (2x-4)2
Answer: 16

Explanation:
The full expanded expression is 4x^2-16x+16
Which you can get through these steps
(2x-4)^2
(2x-4)(2x-4)
y(2x-4) ...... let y = 2x-4
2xy - 4y
2x( y ) - 4( y )
2x( 2x-4) - 4( 2x-4 ) .... plug in y = 2x-4
4x^2 - 8x - 8x + 16
4x^2 - 16x + 16
The question is an illustration of expansion and factorization.
The last term of the expression is 16.
We have:
[tex](2x - 4)^2[/tex]
Expand
[tex](2x - 4)^2 = (2x - 4) \times (2x - 4)[/tex]
Further expand
[tex](2x - 4)^2 = 2x(2x - 4) - 4(2x - 4)[/tex]
Open brackets
[tex](2x - 4)^2 = 4x^2 - 8x - 48x + 16[/tex]
[tex](2x - 4)^2 = 4x^2 - 56x + 16[/tex]
Hence, the last term of the expression is 16.

To solve a multiplication of 2 parenthesis, we'll multiply each of the terms on the left with each of the terms on the right. Then, add all of the products together.
First, x (left) with x (right):
[tex]x * x = x^2[/tex]
Next, x (left) with -4 (right):
[tex]x * (-4) = -4x[/tex]
Next, 7 (left) with x (right):
[tex]7 * x = 7x[/tex]
Finally, 7 (left) with -4 (right):
[tex]7 * (-4) = -28[/tex]
Now we have 4 products. To find the result of the entire expression, we need to add all of these together.
[tex]x^2 - 4x + 7x - 28[/tex]
We can simplify -4x+7x to 3x:
[tex]x^2 + 3x-28[/tex]
Answer: [tex]f(x)*g(x) = x^2+3x-28[/tex]
Answer:
[tex] \longmapsto f(x) = x + 7 \\ \longmapsto g(x) = x - 4 \\→ f(x)g(x) = (x + 7)(x - 4) \\ = {x}^{2} - 4x + 7x - 28 \\ = \boxed{ {x}^{2} + 3x - 28}✓[/tex]
x²+3x-28 is the right answer.
