please help on number 2 the table represents a linear relation use the table to identify the y-intercept please help i have an f and a couple zeros plz will give brainly
Answers
Answer:
y = 7x + 4
Step-by-step explanation:
From the table given in the picture attached,
Let the linear equation representing the table is,
y = mx + b
Here, m = Slope of the equation
b = Y-intercept
Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (20, 144) and (24, 172) will be,
m = [tex]\frac{172-144}{24-20}[/tex]
m = [tex]\frac{28}{4}[/tex]
m = 7
By substituting the value of m in the equation,
y = 7x + b
Since, this line passes through a point (20, 144),
By substituting the values of x = 20 and y = 144 in the equation,
144 = 7(20) + b
b = 144 - 140
b = 4
Therefore, equation of the line will be,
y = 7x + 4

What is the equation of the line that passes through the point (-3, 1) and has a
slope of -2?
Answers
Answer:
y = -2x - 5
Step-by-step explanation:
x1 = -3 , y1 = 1 ; m = -2
point slope form : y - y1 = m(x -x1)
y - 1 = -2(x - [-3])
y - 1 = -2(x + 3)
y - 1 = -2x + 3*(-2)
y - 1 = -2x - 6
y = -2x - 6 + 1
y = -2x - 5

The number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.
What is arrangement?Arrangement of the things or object is mean to make the group of them in a systematic order, in all the possible ways.
The number of possible ways to arrange is the n!.
Here, n is the number of objects.
The given letter in the problem is DISPLAY. There is total 7 letters in this word. Now here three words have to be selected.
Here, all the 7 letters are different, thus the combination of selecting three letters from the 7-letter word (DISPLAY) can be given as,
[tex]^7C_3=\dfrac{7\times6\times5}{3\times2\times1}\\[/tex]
[tex]^7C_3=35[/tex]
Thus the number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.

Point M is the midpoint of Ac. Find the coordinates of M. A(2, 3), C(6. 10)
Answers
Answer:
coordinates of M will be (4, [tex]\frac{13}{2}[/tex])
Step-by-step explanation:-
To find the coordinates of the midpoint, we can use this equation:-
[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]
M is the midpoint of AC, where A is (2,3) and B is (6, 10)
So, x1 will be 2,
x2 will be 6
y1 will be 3
and y2 will be 10.
So, substituting these in the equation, we get:-
[tex]\frac{2 + 6}{2} , \frac{3+10}{2}[/tex]
[tex]\frac{8}{2} , \frac{13}{2}[/tex]
4, [tex]\frac{13}{2}[/tex]
So, the coordinates of the point M will be 4, [tex]\frac{13}{2}[/tex]

of $51.09. By what percentage did the stock decline?
Answers
Answer:
1.75
Step-by-step explanation:
just check and that person was wrong
Answer: 1.75%
Step-by-step explanation: new value: $51.09
51.09+0.91=\$52.00
Old value: 51.09+0.91=$52.00
52(1-r)=51.09
52(1−r)=51.09
{52(1-r)}{52} ={51.09}{52}

Step-by-step explanation:
First, we find the circumference of the circle in the center.
(15 - 3 - 3)/2 = 4.5
4.5 is the radius
Equation for circumference: 2*pi*r
2*pi*4.5
9pi
Depending on where you normally use 3.14 or 3.15 for pi changes the answer but for this example I will use 3.14
The circumference of the circle is 28.26
Next, add the other sides of the figure.
28.26 + 3 + 3 + 3 + 3 + 5 + 5 = 50.26

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 centimetres and a height of 2 centimetres. How much wax will the company need to make 270 candles?
Use 3.14 for π, and do not round your answer.
Answers
Answer:
270 = 15,268.14030 in³
Step-by-step explanation:
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and do not round your answer)?
Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³
Using a typical ten digit calculator
3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)
Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.
Multiply the volume of a cylinder by total candles:
56.52 x 270 = 15,260.4 cubic cm
