Answer:
y+4=-3(x+0) or y=-3x-4
Step-by-step explanation:
so you have to make it in form y=mx+b
that would be y=1/3x-2/3
for a perpendicular line, you would need to find the opposite reciprocal of the slope
3/1 or 3 would be the reciprocal, so to make it opposite would be -3
So it would be y-y1 = m(x-x2)
fill it in with the coordinates (0,-4)
y+4=-3(x-0)
to get it to slope intercept form you have to simplify, and after that you get y=-3x-4

Rock Middle School is planning a field trip to a museum. The museum specifies that there needs to be one chaperone for every 4 students. If the maximum number of people allowed on the field trip is 700, what is the maximum number of students able to visit the museum?
Answer:
28000
Step-by-step explanation:
You multiply 4 and 700.
Answer:
525 students
Step-by-step explanation:
There will be 175 chaperones on the trip.
All you need to do is find 1/4 of 700 which is the number of chaperones.
Then subtract it by 700 to find the number of students.

rewrite the equation in Ax+By=C form, use intergers for A, B, and C.
Answer:
2x - y = - 8
Step-by-step explanation:
y - 4 = 2(x + 2) ← distribute
y - 4 = 2x + 4 ( subtract y from both sides )
- 4 = 2x - y + 4 ( subtract 4 from both sides )
- 8 = 2x - y , that is
2x - y = - 8 ← in standard form
with A = 2, B = - 1 and C = - 8
An online game site has two memership plans. The first plan gives you unlimited play for $40 a month. The second plan charges a monthly access fee of $4.25 plus $2.75 for each hour you play. After how many hours do the two plans cost the same?
Answer:
after 13 hours
Step-by-step explanation:
Since the monthly fee is $4.25
so
● $4.25 + ( 2.75 × Number of hours) = 40
● ( 2.75 × Number of hours) = $40 - $4.25
● 35.75/ 2.75 = 13
Athlete J runs 2/3 of a mile in 8 minutes. Athlete H runs 2 3/4 miles in 1/2 hour.
1. If Athlete J continues at that speed, how long will it take to run one mile?
2.How long will it take Athlete J to run 5 miles at that same speed?
3.Who runs faster, Athlete J or Athlete H? Explain your answer.
If Athlete J continues at that speed, it will take 12 minutes to run 1 mile
It will take Athlete J 60 minutes to run 5miles
Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.
The formula for calculating the speed of the athlete is expressed as:
Speed = Distance/Time
1) If Athlete J runs 2/3 of a mile in 8 minutes, this can be expressed as:
2/3 miles = 8 minutes
If the athlete runs for 1 mile, then;
1 mile = x
Divide both expressions
2/3 = 8/x
2x = 24
x = 12 minutes
Hence If Athlete J continues at that speed, it will take 12 minutes to run 1 mile
2) if athlete J run 5 miles, the time taken will be expressed as;
2/3(5) = 8/x
2/15 = 8/x
2x = 120
x = 60minutes
Hence it will take Athlete J 60 minutes to run 5miles
3) If Athlete H runs 2 3/4 miles in 1/2 hour, then the speed of athlete H will be expressed as:
Speed = (2 3/4)/0.5
Speed = 2.75/0.5
Speed = 5.5miles/hr
For Athlete J;
Speed = 5/1
Speed = 5 miles/hr
Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola
y = 6-x^2
What are the dimensions of such a rectangle with the greatest possible area?
Width =
Height =
Height: 4 units
Width 2√/2
Explanation:
Start by sketching y = 6 - ². Then draw a rectangle beneath it. You will notice that the width is 2x and the height is 6 ². Area is given by length - times width, so the area function will be A=2x (6 - x²) = 12x - 2x³.
Now you differentiate to find the maximum.
A' = 12 - 6x²
Find critical numbers by setting A' to 0.
x = ± √/2
The derivative is negative at x = 2 and positive at x = 1, which justifies that the rectangle with width of √2 has maximal area.
The height will be y (√2) = 6 – (√2)²) = 4
2. What is the best form to use in order to determine the X- AND y-intercepts?
Answer:
Step-by-step explanation:
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x - 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
1.To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
2.To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
3.To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Answer:
Equivalent Expression: [tex]\displaytext\mathsf{\frac{a^7}{b^8}}[/tex]
Step-by-step explanation:
Given the exponential expression, [tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}}[/tex]:
We could use the Quotient Rule of Exponents where it states that:
[tex]\displaystyle\mathsf{\frac{a^m}{a^n}\:=\:a^{(m\:-\:n)}}[/tex]
Since we have the variables, a and b as the base, we could simply apply the Quotient Rule and subtract their exponents.
[tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}\:=\:a^{(12\:-\:5)}\:b^{(-3\:-\:5)}}[/tex]
[tex]\displaytext\mathsf{=\:a^{7}\:b^{-8}}[/tex]
Next, we must transform the negative exponent of base, b, into positive by applying the Negative Exponent Rule, where it states that:
[tex]\large\text{$ a^{-n}\:=\:\frac{1}{a^{n}} $}[/tex]
Applying the Negative Exponent Rule will result in the following exponential expression:
[tex]\LARGE\text{$ a^{7}\:b^{-8}\:=\:[a^{7}\:\times\:\frac{1}{b^8}]\:=\:\frac{a^7}{b^8} $}[/tex]
Therefore, the equivalent expression is: [tex]\LARGE\text{$ \frac{a^7}{b^8} $}[/tex].

Calculate the size of angle x.
angle x =
The size of angle x from the figure is 16 degrees
The sum of the interior angle of a triangle is 180 degrees, hence to get the value of X, we will take the sum of all the given angles and equate them to 180 degrees.
127 + 37 + X = 180
164 + x = 180
Subtract 164 from both sides
164 + x - 164 = 180 - 164
x =16 degrees
Hence the size of angle x from the figure is 16 degrees

Linear or non linear?
Answer:
Linear
Step-by-step explanation:
This is linear because using the data you have provided we can work out that the equation is y= -5x+27
y= mx+ c (c is the gradient)
This equation shows that the line is straight (also shown in the picture) and therefore must make it a linear graph.
For the graph to be non linear, the graph would be curved but this would mean the equation would have to be a quadratic - which it isn't.

Solve by elimination
- 2x + y = 16
- 4x - 3y = 2
Choices
(2,2)
(2,1)
(-2,2)
(-2,-2)
Answer:
Step-by-step explanation:
To solve this, what you first should do is make one of the variables equal, that way you can eliminate that variable and only have to solve one of them. Let's eliminate y, since that one is easier. As you can see, the y in the first equation is 3 times less than the y in the second, so you would multiply everything the first equation by 3 to help eliminate y. After doing this, you would have -6x + 3y = 48, with which you will add to the second equation, which leaves you with -10x = 50. Since you have a negative x, multiplying both sides by a negative sign will make it much easier to find x's value, which gives you -5 as x's value, so x = -5. Now keep this aside, because it will help you solve.
Now that you have the value of x (-5), you should replace one of the equations with x's value, so let's just do this to the second equation. Now you have 20 - 3y = 2. Here, you should take the 20 to the right side to isolate 3y from the numbers, which leaves you with -3y = -18. This gives tells you, after simplifying, that y = 6.
And since the order pair is always (x,y), your answer would be (-5, 6). STILL EDITING ANSWER!

What is the Least Common Denominator (LCD) of 1/8 and 1/4?
Answer: 8
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/8, 1/4
For the denominators (8, 4) the least common multiple (LCM) is 8.
LCM(8, 4)
Therefore, the least common denominator (LCD) is 8.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/8 = 1/8 × 1/1 = 1/8
1/4 = 1/4 × 2/2 = 2/8
What is the equation in point slope form of the line that passes through the point (3, 1) and has a slope of –2?
Drag and drop the appropriate number, symbol, or variable to each box.
Answer:
y - 1 = -2(x - 3)
Step-by-step explanation:
Given the point, (3, 1) and the slope of –2:
Let (x₁, y₁) = (3, 1)
slope: m = -2
Substitute these values into the following point-slope form:
y - y₁ = m(x - x₁)
y - 1 = -2(x - 3) ⇒ This is the point-slope form.
