Answer: y = 1x -3
The 1 is not necessary so
y= x - 3
Step-by-step explanation:
(y- y1) = m(x -x1). First
Substitute y and x-values from the given coordinates and solve for x.
7-(-1)=m(10-2)
8 = m(8) 8/8=1 T
m= 1 The slope, m is 1
Then substitute values of y and x from either given coordinate into the equation and solve for b, the y-intercept.
y=mx+b
-1= 1(2)+b
-1=2+b subtract 2 from both sides.
-1-2 = b
-3 = b
OR
7= 10 + b
-10 +7 = b
-3 = b
Finally, write the equation with the values for m and b
y = 1x +(-3) Simplify & Rewrite
y= x - 3

Step-by-step explanation:
Im not sure at all tho. But I hope this helps :/
I need real answers please help i'm having a lot of trouble with this. it been 2 days i can't get
so first take two sets of coordinates. Find the slope using the slope formula; m=(Y₂-Y₁)/(X₂-X₁). Plug in the x and y values. let's use (14,21) and (2,3). Our equation would be (3-21)/(2-14)=(-18)/(-12)=1.5. Then use point-slope form; (Y-Y₁)=m(X-X₁). Plug in the x and y values, and get (y-21)=1.5(x-14). Simplify and get y-21=1.5x-21. Add 21 on both sides, and you get your final equation y=1.5x. So equation 1 will match A. Then do those same steps for the rest of the equations.

What is the interquartile range of this data?
6
7
8
9
Step 1: Find Q2
Note - Q2 is basically the median of the set
We see that the two numbers in the middle are 28 and 32.
To get the median, find the average of 28 and 32.
28 + 32 = 60, 60/2 = 30
Q2 = 30
Step 2: Find Q1
The median splits the set. So anything before 30, is what we should focus on.
In this case, it's: 12, 16, 20, 24, and 28
Find the median of those five numbers. We get: 20
Q1 = 20
Step 3: Find Q3
Similar to before, focus on the numbers after 30.
In this case, it's: 32, 36, 40, 44, 48
Find the median of those five numbers. We get: 40
Q3 = 40
Step 4: Find the IQR
The IQR (Interquartile Range), as shown in its name, is found by subtracting Q3 and Q1.
Q3 - Q1 = 40 - 20 =20
IQR = 20
Answer:
20

The reason we multiply x by 100 is because 0.1515... has 2 repeating digits and 100 has two zeros.
I hope this helps! A brainliest would be much appreciated :)
The equivalent fraction for the given repeating decimal is 15/99.
The given decimal is 0.1515.....
We need to represent the given repeating decimal to an equivalent fraction.
How to convert a repeating decimal to a fraction?The repeating decimal to fraction steps of conversion are given below:
Step 1: Identify the repeating digits in the given decimal number.
Step 2: Equate the decimal number with x or any other variable.
Step 3: Place the repeating digits to the left of the decimal point by multiplying the equation obtained in step 2 by a power of 10 equal to the number of repeating digits. This way you will get another equation.
Step 4: Subtract the equation obtained in step 2 from the equation obtained in step 3.
Step 5: Simplify to get the answer.
Now, in the given repeating decimal 2 digits are repeating.
Take, n=0.1515....--------(1)
Multiply both sides of equation (1) by 100.
That is, 100n=15.1515.......(2)
Now, subtract equation (1) from equation (2).
That is, 100n-n=15.1515......-0.1515......
⇒99n=15
⇒n=15/99
Therefore, the equivalent fraction for the given repeating decimal is 15/99.

What is the surface area of this figure?
Enter your answer in the box.
ft²
1222
Reason for this answer:
The surface area of given figure is 1222 [tex]ft^{2}[/tex]
What is Surface Area ?Surface area is the amount of space covering the outside of a three-dimensional shape.
Firstly, Take the cuboidal base.
We will find the area of the front and back face which is shape of rectangle.
The side faces of rectangles and lastly the bottom face.
Area of Front and back face= area of 2 rectangles= 2 x length x breadth
= 2 x 19 x 11
= 418 [tex]ft^{2}[/tex]
Area of side faces = area of 2 rectangles= 2 x side x side
= 2 x 11 x 9
=198 [tex]ft^{2}[/tex]
Area of bottom = Length x breadth= 19 x 9
= 171 [tex]ft^{2}[/tex]
Now, area of faces remaining on the side of the triangular prism.
There are two rectangle of measurement : length= 9 ft and breadth = 4.5 ft
Area of two remaining faces on top other than triangular base= l x b= 2 x (9 x4.5)
= 81 [tex]ft^{2}[/tex]
At last, the side faces of triangular prism whose area be,=2 x 13 x 9
= 234 [tex]ft^{2}[/tex]
Area of front and back face of triangular prism= 2 x ( [tex]\frac{1}{2}[/tex] x b x h )
= 2 x 0.5 x 10 x 12
= 120[tex]ft^{2}[/tex]
Total Surface Area of the figure is,= 418+ 198+171+234+81+120
= 1222 [tex]ft^{2}[/tex]
