your Answer will be
x=23 or x=−9
6x - 2y= 18
Find the x-intercept and the y-interc
Then use them to graph the line.
x-intercept(s): (3,0)
y-intercept(s): (0,−9)
Answer:
The x is -3 and the y is -9 so the answer is (-3,-9)
Step-by-step explanation:
6x-2y=18
-6x -6x
-2y=-6x+18
-2y/-2=-6x/-2+18/-2
y= -3x -9
To graph you just mark it at -9 and go down 3 up 1; or you could go up 3 down 1
Hope this helps :) Have a wonderful day and wish you luck on your test :)
John takes one step every second, and each step is 33 inches long. How many miles per hour is John walking, given that 5280 feet = 1 mile? Express your answer as a decimal to the nearest thousandth.
Answer:
[tex]Speed = 1.875 miles/hour[/tex]
Step-by-step explanation:
Given
[tex]Speed = 33in/s[/tex]
Required
Convert to mile/hour
[tex]1\ inch = 1/63360\ mile[/tex]
[tex]1\sec = 1/3600\ hr[/tex]
So:
[tex]Speed = 33in/s[/tex]
[tex]Speed = \frac{33 * 1/63360}{1/3600}[/tex]
[tex]Speed = \frac{33/63360}{1/3600}[/tex]
[tex]Speed = \frac{33}{63360}/\frac{1}{3600}[/tex]
[tex]Speed = \frac{33}{63360} * \frac{3600}{1}[/tex]
[tex]Speed = \frac{33 * 3600}{63360}[/tex]
[tex]Speed = \frac{118800}{63360}[/tex]
[tex]Speed = 1.875 miles/hour[/tex]
Hence, John is working at 1875 miles per hour
Answer:
1.875 a hour
Step-by-step explanation:
It is this way because 33/12 is 2.75 so he is walking 2.75 feet a second
Multiply the second by 3600 and the 2.75 feet by 3600 and you get 9900
per hour divide 9900 by 5280 and you get 1.875

Write −2.32
as a mixed number in simplest form
Answer:
first I put -2.32 into a improper fraction and then I simplified to this - 2 8/25
We need to find the given numbers mixed fraction representation.
The given numbers mixed fraction form is [tex]-2\dfrac{8}{25}[/tex].
The given number is [tex]-2.32[/tex].
Let us remove the negative sign for solving the question.
The negative sign can be added at the end.
[tex]2.32=2+0.32[/tex]
[tex]=2+\dfrac{32}{100}[/tex]
Dividing the fraction by common factors we get
[tex]2+\dfrac{8}{25}=2\dfrac{8}{25}[/tex]
The given numbers mixed fraction form is [tex]-2\dfrac{8}{25}[/tex].

Sally deposits $4,000 in a certificate of deposit that pays 2.12% simple interest. What is her balance after one year?
Answer:
4084.80
Step-by-step explanation:
Interest = Principal * Interest * Time
= 4000 * 0.0212 * 1
= 84.8
balance = deposit amount + interest
= 4000 + 84.8
= 4084.80
Based on then information given her balance after one year is: $4048.80.
Using this formula
A = P (1 + r)^t
Where:
A=Amount=?
Principal=$4,000
r=Interest rate=2.12% or 0.0212
t=time=1 year
Let plug in the formula
A=4000(1 + 0.0212)^1
A= 4000(1.0212)
A= $4048.80
Inconclusion her balance after one year is: $4048.80.

A hockey player strikes a hockey puck. The height of the puck increases until it reaches and maximum height of 3 feet, 55 feet away from the player. The height y (in feet) of a second hockey puck is modeled by y=x(0.15-0.001x), where x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answer:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.
Step-by-step explanation:
Maximum height of 3 feet is attained by the hockey puck of first player is when the puck is 55 feet away from the player.
It is at the mid point of the total horizontal distance to be traveled by the hockey puck.
So, the horizontal distance traveled by hockey puck of first player = 55 + 55 = 110 feet
Second player:
[tex]y=x(0.15-0.001x)[/tex]
where [tex]y[/tex] is the height of a second hockey puck
[tex]x[/tex] is the horizontal distance.
When the puck hits the ground, [tex]y=0[/tex]
Now, let us find the value of [tex]x[/tex].
[tex]\Rightarrow 0=x(0.15-0.001x)[/tex]
At [tex]x=0[/tex] feet or [tex]x=150[/tex] feet, [tex]y=0[/tex]
Therefore, the distance traveled by second hockey puck is 150 feet.
So, the answer is:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.
Kelly wants to decrease her daily sugar intake from 40 grams of sugar to 30 grams of sugar. By what percentage does Kelly want to decrease her daily intake of sugar? O 10% O 25% O 75% O 905
Kelly wants to reduce her sugar consumption by 25%.
Kelly wants to go from consuming 40 grams to 30 grams of sugar.
The percentage she wants to decrease by can be found by the formula:
= (Old intake - New Intake) / Old Intake
Solve the formula and the percentage is:
= (40 - 30) / 40
= 0.25
= 25%
In conclusion, Kelly wants to decrease her sugar intake by 25%.

Cooper Middle School has a goal of collecting more than 1,000 cans of food in a food drive. So far, 375 cans have been collected. During the last 13 days of the drive, at least how many cans must be collected each day in order to meet the goal?
Answer:
48 cans each day
Step-by-step explanation:
This can be represented as:
[tex]375+13c\geq 1,000[/tex]
(13c represents the number of cans, needed within the past 13 days)
First subtract both sides by 375
[tex]13c\geq 625[/tex]
Then divide both sides by 13 to get your answer of:
[tex]c\geq 48[/tex]
Answer:
48
Step-by-step explanation:
1000-375=625
625/13=48.0769

Mis the midpoint of CD. Given
the coordinates of one endpoint
C(10,-5) and the midpoint
M(4,0), find the coordinates of
the other endpoint D of CD.
a) (7.)
b) (-2)
c) (-2,5)
d) (7,5)
e) (1,1)
Answer:
(-2,5)
Step-by-step explanation:
use formula: m= ([tex]\frac{x^{1}+x^{2} }{2} , \frac{y^{1}+y^{2} }{2}[/tex])
midpoint(m) equals (4,0) and C is (10,-5)
C represents [tex](x^{1} ,y^{1})[/tex] and other endpoint D represents [tex](x^{2}, y^{2} )[/tex] so:
(4,0) = [tex](\frac{10+x^{2} }{2} , \frac{-5+y^{2} }{2} )[/tex]
4 = [tex]\frac{10+x^{2} }{2}[/tex]
[tex]4*2 = (\frac{10+x^{2} }{2} )2[/tex] Get rid of 2 by multiplying both sides by 2
8 = [tex]10 + x^{2}[/tex] Subtract both sides by 10
[tex]x^{2} = -2[/tex] x coordinate of D = -2
To find y coordinate of D:
0 = [tex]\frac{-5+y^{2} }{2}[/tex] Get rid of 2 by multiply both sides by 2
0 = [tex]-5 + y^{2}[/tex] Add both sides by 5
[tex]y^{2} = 5[/tex] y coordinate of D = 5
So if x-coordinate of D= -2 and y-coordinate of D=5, the coordinates for D is (-2,5)

Answer:
The following points are on the line
(x,y) = (2,120)(x,y) = (3,180)(x,y) = (4,240)There are other points on the line, but I'm focusing on the points where the three filled in circles are shown. I'm ignoring (0,0) because that point won't be useful for the next section below.
Pick any of the three points and divide y over x
y/x = 120/2 = 60y/x = 180/3 = 60y/x = 240/3 = 60Whatever point you choose, you'll get the same ratio. The constant of proportionality is 60.
In the context of this problem, the 60 refers to the speed of the car.
The car travels 60 miles in 1 hour, or at a speed of 60 mph.
