y = 7x + 10 y= -4x - 23
Or 7x + 10 = -4x - 23
I need to show my work too hurry!!
Step-by-step explanation:
7x + 4x = -23 - 10
or, 11x = -33
or, x = -33/11
or, x = -3
Therefore, x = -3.

Radius of the circle is 20cm. there are two chords of lengths.
32cm, what will be the dis-
tance of these chords from
the centre of the circle?
9514 1404 393
Answer:
12 cm
Step-by-step explanation:
The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.
The chords are 12 cm from the center.
_____
You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...
c² + d² = r²
16² + d² = 20²
d² = 400 -256 = 144
d = √144 = 12 . . . . . cm
how do i calculate the range? {mean, median, mode, range} pls help ASAP
Also, can you tell me in the comments how to delete an answer or remove it?
Answer:
The anwer is below.
Step-by-step explanation:
To calculate mean a.k.a average of something is when you add all of the numbers in the set and then multiply by the number of numbers there were.
an example : 4, 5,6,7 = 4+ 5 + 6 + 7 + 3 = 25 divided by 5 ( the number of numbers there were ) which is 5 so the mean is 5
To calculate the median you have to organize the set of numbers from least to greatest choose the middle number and that's the median, If there is an even number of numbers in the set then you add the two middle numbers and divide it by 2.
an example : 5,7, 8, 4 = 4, 5, 7 , 8 = the middle numbers = 5 + 7 = 12 divided by 2 = 6
To calculate the mode you have to see which numbers comes more often in the set of numbers, If there are two different numbers that come often even if one is higher include them in the mode.
An example - 5,6,6,6,6,7,7,7. The mode in this is 6 but 7 comes often to so if your teacher tells you to include more than one mode in these kinds of situation you include 7 or in general you don't have to
To calculate the range you choose the greatest and the lowest numbers and substract the highest to the lowest number in the set.
An example 5, 6, 7 , 9 , 8 = 9 ( the highest number in this set) - ( substraction) 5 ( the lowest number in this set) and 9 - 5 = 4 so the range is 4
If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.
Answer:
$57.51
Step-by-step explanation:
If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.
The formula for the original price =
= Sales price/1 - Percentage discount
Percentage discount = 35% = 0.35
Original price = $37.38/1 - 0.35
= $37.38/0.65
= $57.507692308
Approximately = $57.51
Therefore, the original price H= $57.51
If the area of a square with side x is equal to the area of a triangle with base x, then find the altitude of the triangle.
Answer:
[tex]h= 2x[/tex]
Step-by-step explanation:
Given
Square
[tex]Side = x[/tex]
Triangle
[tex]Base = x[/tex]
[tex]Altitude = h[/tex]
Required
Find h, if both shapes have the same area
The area of the square is:
[tex]Area = x * x[/tex]
[tex]Area = x^2[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} * Base*Height[/tex]
[tex]Area = \frac{1}{2} * x*h[/tex]
Equate both areas
[tex]x^2 = \frac{1}{2} * x*h[/tex]
Divide both sides by x
[tex]x = \frac{1}{2} *h[/tex]
Multiply both sides by 2
[tex]2*x = \frac{1}{2} *h*2[/tex]
[tex]2x = h[/tex]
[tex]h= 2x[/tex]

Randy wanted to survey to determine the most preferred pet of the residents in his city.Which method of samplingBEST represents the most unbiased opinion?
Answer:
Survey 100 residents who have pets completely randomly
Step-by-step explanation:
The best sampling method would be to Survey 100 residents who have pets completely randomly. This would provide first-hand information from actual pet owners which would make the results valid. Also, by choosing the individuals to survey completely randomly it allows for the data to be unbiased and representative of the entire pet owner population in the city. This makes the data gathered completely unbiased and valid.

Find the area of the triangle where C = 18.5°, a = 32.4 cm, b = 49.2 cm
HEHE HELP
Answer:
questions mistake look questions and apply the formula 1/2 B×H
if you have a triangle and don't know where are the base and the high use this formula
area = 0.5 × side × side × sin the angle between the 2 sides
area = o.5 (32.4) (49.2) (sin 18.5)
= 797.04 × sin 18.5

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
4x + 2y = 8 be equation (1)
Now , the coordinates of the point P = P ( 0 , y )
The coordinates of the point Q = Q ( x , 0 )
Substituting the values in the equation , we get
when x = 0
4 ( 0 ) + 2y = 8
2y = 8
y = 4
So , the coordinates of the point P = P ( 0 , 4 )
when y = 0
4x + 2 ( 0 ) = 8
4x = 8
x = 2
So , the coordinates of the point Q = Q ( 2 , 0 )
Now , the equation of line is 4x + 2y = 8
when x = { -2 , -1 , 0 , 1 , 2 , 3 }
The values of y are y = { 8 , 6 , 4 , 2 , 0 }
So, the line is plotted in the graph
Hence , the equation of line is 4x + 2y = 8

How do you divide -15/-5
Answer:
3
Step-by-step explanation:
When you divide two negative numbers, the answer is positive. Since - 15 and -5 are both negative, the answer will have to be positive. Divide 15/5 (just as you would with postive numbers) to get 3 and don't do anything else. The answer has to be 3 because 3 * - 5 = -15 (the opposite of division is multiplication).

Answer:
r = sq rt [v/(h x Pi)]
r = 1.69
Step-by-step explanation:
v=h x Pi x r^2
r^2 = v/(h x Pi)
r = sq rt [v/(h x Pi)]
r = sq rt [67.57 / (7.5 x 3.14)]
r = sq rt 2.8692

Domain is the set of x-values that can be inputted into function f(x) Range is the set of y-values that are outputted by function f(x) Vertical Line Test - no function can have the same x-value for different y-coordinatesStep-by-step explanation:
According to the graph, our x-values span from 0 to 4. Since both are closed dot, they are inclusive in the domain:
Interval Notation - [0, 4]
Inequality Notation - 0 ≤ x ≤ 4
According to the graph, our y-values span from 0 to 4. Since both are closed dot, they are inclusive in the range:
Interval Notation - [0, 4]
Inequality Notation - 0 ≤ x ≤ 4
Since we see that each x-value has a unique y-value and passes the vertical line test.
∴ the relation is a function.

A rectangular room is 3 times as long as it is wide, and its perimeter is 48 meters. Find the dimension of the room.
The length is : _____ meters and the width is ______ meters.
The length and width are 18 meters and 6 meters respectively.
Given that
The perimeter of the rectangle is 48 meters.The width be x.The length be 3x.We know that
The perimeter of the rectangle be
48 = 2 (length + breadth)
48 = 2(3x + x)
48 = 6x + 2x
48 = 8x
x = 6
So, the width is 6 meters.
And, the length be 18 meters.
Therefore we can conclude that The length and width are 18 meters and 6 meters respectively.
