A line passes through the point (-6, 9) and has a slope of 4/3. Write an equation in slope-intercept form for this line.
Answer:
y = 4/3x + 17 .
Step-by-step explanation:
Use the point-slope form of a line:
y - y1 = m(x - x1)
y - 9 = 4/3(x - -6)
y - 9 = 4/3x + 8
y = 4/3x + 17 <--------- Slope-intercept form.
Calculate the side lengths using the given scale.
Answer:
x= 5× 17
= 85milimetres
y= 65÷ 5
=13milimetres

A circle is drawn inside a square.
a
20 cm
The square has a height of 20 cm.
Work out the shaded area.
Give your answer in terms of t.
Shaded area = 21.46
Step-by-step explanation:
First find area of square,
Area = length × width
A = 20 × 20
A = 400 cm^2
Secondly, find area of circle
Area of circle = (π)r^2
A = (π)10^2
A = 100 π
Thirdly, find the area outside of the circle
Area of square - Area of circle
400cm^2 - 100π
= 85.84
lastly divide the answer by 4 to find the shaded area
85.84 ÷ 4
= 21.46

The four angles of a quadrilateral are 30°, 60°, 150°, and 120° if the four vertices of an inscribed quadrilateral divide a circle in the ratio 1:2:5:4.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners.
We have the four vertices of an inscribed quadrilateral divide a circle in the ratio:
1:2:5:4
Let the sides of the quadrilateral be x, 2x, 5x, 4x.
We know the sum of all angles of quadrilateral = 360°
x+2x+5x+4x=360
12x = 360
First angle, x = 30°
Seconds angle, 2x = 2×30 ⇒ 60°
Third angle, 5x = 5×30 ⇒ 150°
Fourth angle, 4x = 4×30 ⇒ 120°
Thus, the four angles of a quadrilateral are 30°, 60°, 150°, and 120°

median is 16 ducky quack
Answer:
16
Step-by-step explanation:
Median, also known as the "middle" value in a data set. To be able to find the median, your data needs to be in numerical order.
Quiz scores:
9, 13, 20, 15, 18, 17
Arrange in numerical order:
9, 13, 15, 17, 18, 20
Find the "middle" value:
9, 13, 15, 17, 18, 20
When there are two middle values, you add them up and divide it by 2.
15 + 17 = 32
32/2 = 16
Therefore, the median, "middle" value of this student's quizzes is 16.

Solving the system of equations, it is found that the before-tax price of a chicken dinner is of $15.5.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable c: Price of a chicken dinner.Variable s: Price of a steak dinner.The system is given by:
27c+ 17s = 809.50
46c + 34s = 1,495.00
Multiplying the second equation by -0.5 and adding with the first we can remove s, hence:
27c+ 17s = 809.50
-23c - 17s = -747.50.
4c = 62.
c = 62/4.
c = 15.5.
The before-tax price of a chicken dinner is of $15.5.

Find the area of a regular hexagon with a perimeter of 12cm.
Answer:
[tex]6\sqrt{3}[/tex] [tex]cm^{2}[/tex]
Step-by-step explanation:
Here is a fact to remember. A hexagon is always made up of 6 equilateral triangles.
So if the perimeter of the Hexagon is 12 cm, then each side is 2 cm.
The area of an equilateral triangle is [tex]\frac{s^{2}\sqrt{3} }{4}[/tex].
So plugging in 2 gets us the area of one triangle.
s = 2
[tex]2^{2}\sqrt{3}/4 = \sqrt3[/tex]
The area of 6 triangles will be [tex]6\sqrt{3}[/tex] [tex]cm^{2}[/tex].

SOMEONE HELP PLEASE! I HATE ANGLES
Answer:
a = 51°
b = 67°
Step-by-step explanation:
Angle a is equal to 51 since it is vertically opposite to the angle on top of it.
Angles in a triangle add up to 180 so Angles a,b and 62 should add up to 180:
a+b+62=180
51+b+62=180
b= 180-(51+62)
b= 180-113
b= 67
y=3(x+2)^2+4 solve please and thank you!
Answer:
Step-by-step explanation:
Subtract 4 from both sides
y - 4 = 3(x+2)^2
Divide 3 from both sides
(y-4)/3 = (x+2)^2
Square root both sides
SQRT((y-4)/3) = x + 2
Subtract 2 from both sides
x = SQRT((y-4)/3) - 2

195, how many feet per minute is he
traveling?
The feet per minute that John is travelling down 195 is 4840 feet per minute.
How many feet per minute is he traveling?Average speed is the total distance travelled per time. It is determined by dividing total distance travelled by total time.
In order to convert 55 miles per hour to feet per minute, we have to know the unit of conversion :
1 mile = 5280 feet
1 hour = 60 minutes
55 x (5280 / 60) = 4840 feet per minute

I NEED THIS ANSWER IN THE NEXT 10 MINUTES
Answer:
D
Step-by-step explanation:
Consecutive integers are integers with the progression n, n+1, n+2 (EXAMPLE)
Since w, x, y are consecutive integers, that means w, w+1, w+2; x = w+1, y = w+2
By referring to D,
w + x + y = w + w+1 + w+2
= 3w + 3
Hence, D is true.
Answer:
D
Step-by-step explanation:
A is wrong because if w is -1, x is 0, and y is 1, then wy is negative.
B is wrong because if w is -1, x is 0, and y is 1, then -1 + 1 = 0, which is x.
C is wrong because if w is -1, x is 0, and y is 1, then w³ + 3 = -1 + 3 = 2, which is greater than w + x + y which is 0.
D is correct because w + x + y is always equal to 3w + 3. For example, if w is 1, x is 2, and y is 3, then w + x + y = 6. 3w + 3 = 3(1) + 3 = 6.
E is wrong because if w is 1, x is 2, and y is 3, then wx is 2 and xy is 6, which means xy is greater than wx.

=========================================================
Explanation:
A nominal variable is one where usually a name is attached to it, instead of a number. Something like "mood" is nominal because it takes on the options of "happy", "sad", "angry", etc which are all non-numeric names. We can't do math on them. The same goes for colors, blood type, dog breed, nationality, and month names.
An ordinal variable is one where we can rank the names but we can't exactly do math on them. An example of this would be pain severity (from "no pain" to "in extreme pain") since we can rank and order the pain levels in a natural order. Another example is satisfcation rating, rank in class, and clothing sizes.
A discrete variable is one that takes on finitely many values between two endpoints. Usually (but not always) discrete values are whole numbers. When it comes to counting the number of people or objects, we turn to a discrete variable. With discrete variables, it doesn't make sense to have a midpoint between say 1 and 2 because we cannot have 1.5 of a person.
A continouous variable is one where we can pick any real number in a given interval. Midpoints make sense here now because we can select the midpoint of say 1 and 2 to get 1.5; an example of a continuous variable is someone's height, wind speed, water temperature, or the voltage of electricity.
