What is the equation of a line perpendicular to y=x+12 that passes through (12,3) ?
I KNOW THE STEPS BUT I NEED TO KNOW IF M = 1 in y=mx+b
Answer:
[tex]y=-x+15[/tex]
Step-by-step explanation:
Slope-intercept form is written as [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
Any line perpendicular to a given line with slope [tex]m[/tex] has a slope of [tex]-\frac{1}{m}[/tex]. Therefore, the slope of a line perpendicular to [tex]y=x+12[/tex] is [tex]-\frac{1}{1}=-1[/tex].
We can now plug the coordinate it passes through into our slope-intercept form equation to solve for the y-intercept:
[tex]3=-1(12)+b,\\b=15[/tex]
Therefore, the equation of the line that is perpendicular to [tex]y=x+12[/tex] and passes through the coordinates [tex](12,3)[/tex] is [tex]\fbox{$y=-x+15$}[/tex].
I have a square with a side of 5.25 in. There is a circle inside this square that is big enough to touch all four sides. What is the area that is not inside the circle?
Answer:
5.9125in^2
Step-by-step explanation:
Step one:
Given data
Dimension of square= 5.25 in
Area of sqaure= 5.25^2= 27.5625 in^2
We are told that the sides of the circle touch the sides of the square
hence the diameter of the circle is 5.25in
radius= 5.25/2= 2.625 in
Area of circle= πr^2
Area of circle = 3.142*2.625^2
Area of circle=3.142*6.890625
Area of circle= 21.65 in^2
Step two:
The area that is not inside the circle
=Area of square-Area of circle
=27.5625- 21.65
=5.9125in^2

Convert the equation `8x-4y=24` into slope intercept form. SHOW WORK TO SUPPORT.
8x-4y=24
sub 8x from both sides
-4y=24-8x
sub 24
-4y-24=-8x
add -4y
-24=4y=8x
Answer:
y=2x-6
Step-by-step explanation:
First isolate the variable. You're trying to find y, so you need to ultimately leave y by itself.
8x-4y=24
Subtract 8x from both sides to cancel out the 8.
You should have the equation below left:
-4y= -8x+24
Now, divide everything by negative for so that you are only left with the y.
You should have the equation below left.
y=2x-6

Rose went on a shopping trip to Richmond. She purchased a calculator originally priced at $100 but discounted 80%. If sales tax in Richmond is 15%, what was the total cost? $
Answer:
The total cost is [tex]\$23[/tex].
Step-by-step explanation:
Given: Original price of calculator is [tex]\$100[/tex], discount is [tex]80\%[/tex] and the sales tax is [tex]15\%[/tex].
To find: The total cost
Solution:
We have,
Original price of calculator[tex]=\$100[/tex]
Discount [tex]=80\%[/tex]
Sales tax [tex]=15\%[/tex]
Now, first we need to find the cost after applying the discount.
So, discount [tex]=\frac{80}{100}\times100=\$80[/tex]
Therefore, the cost after applying the discount
[tex]=\$100-\$80=\$20[/tex]
Now, we have to find the sales tax. Therefore,
Sales tax [tex]=\frac{15}{100}\times20=\$3[/tex]
So, the total cost is [tex]\$20+\$3=\$23[/tex].
Hence, the total cost is [tex]\$23[/tex].
Answer:
$23

Answer:

Step-by-step explanation:
This is a seven-sided pentagon. We can find the total sum of all the angles in the pentagon first.
Sum of angles in a pentagon = (7-2) × 180
= 5 × 180
= 900
∠B = 900 - 148 - 90 - 142 - 130 - 129 - 120
= 141
Remember:
Formula of sum of angles in pentagon = (n-2) × 180 where n is the number of sides the pentagon has. Hope this helps :)

write a similarly statement comparing the two triangles
Answer:
C. ΔBDC+~+ΔEDA
Step-by-step explanation:
Two triangles are said to be similar if their sides and angles are relation in a definite proportion. So that, comparing the triangles (ΔBDC and ΔEDA) in the given diagram;
<B ~ <E
<C ~ <A
D is a common angle to both triangles (right angle).
Also,
BC ~ EA
DC ~ DA
BD ~ ED
Thus, the statement that compares the two triangles is:
ΔBDC+~+ΔEDA (similarity property)

Solve the following proportion: 8/r = 18/12
Answer:
r=16/3 if u want me to explain i can
Step-by-step explanation:
Simplify 18/12 to 3/2
8/2=3/2
Multiply both sides by r.
18=3/2r
Simplify 3/2r to 3r/2
8=3/2r
Multiply both sides by 2.
8×2=3r
Simplify 8 x 2 to 16
16=3r
Divide both sides by 3
so the answer is r=16/3

Do these 3side lengths from a right triangle 13,80and 81
Answer:
no
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 81
81² = 6561
13² + 80² = 169 + 6400 = 6569
Since 6561 ≠ 6569 then they do not form a right triangle
Using reverse Pythagoras theorem, the three sides of lengths of triangle does not form right triangle.
What is reverse Pythagoras theorem?Reverse Pythagoras theorem states that "the square of the longest side is equal to the sum of the squares on the other two sides then the triangle is right triangle".
What is right triangle?
A triangle in which "one angle is 90° and the other two sides are perpendicular to each other is called right triangle."
According to the question,
Three sides lengths of triangle 13, 80 and 81. In order to find this triangle is right triangle or not.
Let a = 13, b=80, and c = 81
Reverse Pythagoras theorem c² = a² + b²
(81)² = (13)² + (80)²
6561 = 169 + 6400
6561 ≠ 6569
Hence, using reverse Pythagoras theorem, the three sides of lengths of triangle does not form right triangle.
