Write the equation of a line that passes through the points (6, 8) and ( -2, 4) in
slope intercept form
Answers
Answer:
Equation of a line that passes through the points (6, 8) and ( -2, 4) in
slope intercept form is
[tex]y =-\frac{1}{2} x + 11[/tex]
Step-by-step explanation:
General Equation of straight line is
[tex]y-y_1 =\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex] ---------- (1)
Here
[tex](x_1, y_1) = (6, 8) \ \ and \ \ (x_2, y_2) = (-2, 4)[/tex]
Substituting values in (1)
[tex]y-8 =\frac{4-8}{-2-6}(x-6)[/tex]
Simplifying it further
[tex]y-8 =-\frac{1}{2}(x-6)[/tex]
[tex]y =-\frac{1}{2} x + \frac{1}{2} 6 + 8[/tex]
[tex]y =-\frac{1}{2} x + 3 + 8[/tex]
[tex]y =-\frac{1}{2} x + 11[/tex]

You've been saving your allowance to buy some new video games you head to the mall to do some shopping you say that two stores are having a big sale on video games GameWorld is selling for video games for $68.00 Best Bargains is selling 6 video games for $99.00 If you only want to buy one video game which store will give you the better deal explain.
Answers
Answer: Best Bargains will give a better deal at $16.50 per game.
Step-by-step explanation:
You did not mention the number of games GameWorld was selling for $68.00 and that number is 4.
GameWorld is selling 4 games for $68.00. They are therefore selling one game for:
= 68/4
= $17.00 per game
Best Bargains is selling 6 video games for $99. Each game is:
= 99/6
= $16.50 per games
Best Bargains will give a better deal at $16.50 per game.

25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple One marker is drawn out of the bag, then put back in. How many times would you expect a blue marker to be picked in 80 draws?
Answers
Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times

i just need y intercept and equation
Answers
Answer:
Slope = 4y-intercept = -8Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slope b is the y-interceptGiven the table
x y
2 0
7 20
Determining the slope between (2, 0) and (7, 20)
(x₁, y₁) = (2, 0)
(x₂, y₂) = (7, 20)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [20 - 0] / [7 - 2]
= 20 / 5
= 4
Thus, the slope of the line = m = 4
now substituting the point (2, 0) and the slope m = 4 in the slope-intercept form of a line equation to determine the y-intercept b.
[tex]y = mx+b[/tex]
0 = 4(2) + b
b + 8 = 0
subtract 8 from both sides
b + 8 - 8 = 0 - 8
b = -8
Thus, the y-intercept = -8
Summary:
Slope = 4y-intercept = -8Is the function represented by the table linear?

4x+y=1
Answers
Answer: y=-4x+1
Step-by-step explanation:
The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:
4x+y=1
(4x+y)-4x=1-4x
y=1-4x
y=-4x+1

12 yd

O 21 yd
O 47.13 yd
O 42 yd
Answers
Answer:
C
Step-by-step explanation:
Here, we have a rectangle and a semi-circle and we want to calculate the area of the given shape
To get this, we add the area of the rectangle to the area of the semi-circle
The area of the rectangle is 12 * 9 = 108 square yard
From the diagram, we can see that 9 yards represent the diameter of the semi-circle
What we need to get the area of the semi-circle is the radius and this is half of the diameter
In this case, the half of the diameter is 9/2 = 4.5 yards
The area would be pi * r^2/2
= 3.142 * 4.5^2 = 63.6255/2 = 31.81275 square yards
We proceed to add this to the area of the rectangle
Mathematically, that would be ;
31.81275 + 108 = 139.81275 square yards
The closest answer here is 139.79 which we are going to select
The reason for the answer difference is the version of pi used
Pi could be 22/7 or 3.142
Using both will lead to different answers before approximation
Answer:
139.79 yd^2
108 + 31.79 = 139.79
Explanation:
Rectangle's Area
12 x 9 = 108
Semi Circle's Area
9 x 9 = 81
81 x 3.14 = 254.34
254.34/8 = 31.79
The semi circle's 2 formulas are πr^2/2 and πd^2/8.
Use πd^2/8 if you are using the diameter
the d stands for diameter
Use πr^2/2 if you are using the radius
the r stands for radius
This is what I used for the semi circle
3.14 x 9^2/8
You can also use this
3.14 x 4.5^2/2
Both of those work and you will get the same results.
