Write an equation of the line that passes through (2, – 4) a
and
(0, – 4).
y =
Answer:
y=-4
Step-by-step explanation:
first,
you find the slope by doing
y2-y1/x2-x1 and getting 0.
then plug into point slope form,
y-y1=m(x-x1)
y-(-4)=0(x-2)
y+4=0
y=-4

Van purchased a DVD player on sale. The original selling price was $154.30. The sale price was $132.17. What is the first step in finding the percent markdown? Find the percent markdown.
Answer:
Percentage decrease= 14.34%
Step-by-step explanation:
Giving the following information:
The original selling price was $154.30. The sale price was $132.17.
To calculate the percentage decrease, we need to use the following formula:
Percentage decrease= [(P0 - P1)/P0]*100
Percentage decrease= [(154.3- 132.17)/154.3]*100
Percentage decrease= 14.34%

In American football, the ball is punted by dropping and kicking it before it hits the ground. The height h(t) of the football above the ground in meters t seconds after being punted is affected by gravity and by the punter's kick, and can be represented as the difference of two functions: a(t)=1.4t2, which specifies the effect of gravity on the height of the ball, and v(t)=12.1t+2.5, which specifies the effect of the punt on the ball. With these two functions, h(t)=v(t)-a(t), how high above the ground was the ball when it was punted?
Answer:
h = 8.845 m
Step-by-step explanation:
The height h(t) of the football above the ground in meters t seconds after being punted is affected by gravity and by the punters kick, and can be represented as the difference of two functions:
[tex]a(t)=1.4t^2\\\\v(t)=12.1t+2.5[/tex]
We need to find h(t) such that, h(t)=v(t)-a(t)
So,
[tex]h(t)=12.1t+2.5-1.4t^2\\\\h(t)=-1.4t^2+12.1t+2.5[/tex]
It is a quadratic equation. When we solve it we get :
[tex]h(t)=8.845\ m, -0.2\ m[/tex]
Neglecting negative value,
h(t) = 8.845 m
So, the ball was at a height of 8.845 m when it was punted.

Answer:
slope is 0
Step-by-step explanation:
Answer:There is no slope to this answer. The slope is undefined
Step-by-step explanation: This is because when you use the slope equation (rise over run) you get 1 over 0, because you rise but don't move on the x axis at all. Since you cannot divide by zero the answer is undefined. The slope would be zero if it was a horizontal line for example 0/1 slope.

Ian wants to run 4 1/2 miles to get ready for his upcoming race. He has set up 3 markers the same distance apart to show how far he has run. How far apart are the markers?
Answer:
1 1/2
Step-by-step explanation:
Given that:
Total miles to run = 4 1/2 miles
Number of same distance markers set = 3
The diatances between each marker :
Total distance / number of markers
4 1/2 ÷ 3
9 /2 ÷ 3
9 / 2 * 1 /3
= 9 /6
= 3/2 = 1 1/2
Hence, the distance between each marker = 1 1/2

Answer:
m∠N = 41°
Step-by-step explanation:
Here,
In △MNO, m∠M = (6x + 1°) ...(1)
m∠N = (3x - 10°) ...(2)
m∠0 = (x + 19°) ...(3)
Here, We know that the sum of all angles of a triangle is 180°
Then,
(6x + 1°) + (3x - 10°) + (x + 19°) = 180°
6x + 1° + 3x - 10° + x + 19° = 180°
6x + 3x + x + 1° - 10° + 19° = 180°
10x + 10° = 180°
10x = 180° - 10°
10x = 170°
x = 170° ÷ 10°
x = 17°
Now, put the value of x in (1), (2) and (3)
m∠M = (6x + 1°)
= (6(17) + 1°)
= (102° + 1°)
m∠M = 103°
m∠N = (3x - 10°)
= (3(17) - 10°)
= (51° - 10°)
m∠N = 41°
m∠0 = (x + 19°)
= (17 + 19°)
m∠0 = 36°
Thus, The m∠N = 41°
FOR VERIFICATION ONLY:(6x + 1°) + (3x - 10°) + (x + 19°) = 180°
(6(17) + 1°) + (3(17) - 10°) + (17 + 19°) = 180°
103° + 41° + 36° = 180°
180° = 180°
Hence, L.H.S = R.H.S

write and equation in slope intercept form (y=mx+b) for the graph below
Answer:
y=1/3x+0 or y=1/3x
Step-by-step explanation:
find the slope by taking two points and putting them in
y2 - y1/x2 - x1
so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3
then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)
y - 2 = 1/3(x-6)
when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given
