Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.
If a point X(x, y) is reflected about the y = x line, the new location is X'(y, x)
Triangle ABC has vertices at A(8.-4), B(6,3), and C(-1.-6), if it is reflected about the y = x line, the new location is A'(-4, 8), B'(3, 6), C'(-6, -1)

A carpenter bought bolts to finish a project. In all, the bolts weighed 2 pounds. There are 16 ounces in 1 pound. If each bolt weighed 1/12 ounce, how many bolts did the carpenter buy
Answers
Answer:
384boltsStep-by-step explanation:
Given that there are 16 ounces in 1 pound
the carpenter bought 2 pounds
hence he has 32 ounces altogether
also each bolt weighed 1/12 ounce
Hence in 32 ounces there are
32/1/12
multiply 32 by the inverse of the denominator we have
=32*12/1
=384bolts

Answer:
y = 1/3x + 3
Step-by-step explanation:
Slope form of a equation: y = mx + b. The slope is 1/3, so y = 1/3x + b
Solve for b by plugging the (x, y) coordinate into the equation.
y = 1/3x + b
2 = 1/3(-3) + b
2 = -3/3 + b
2 = -1 + b
b = 3
So your answer is y = 1/3x + 3

You had a lot of spare time this summer because of quarantine, so you and four family members took a 5-day white-water rafting and hiking trip. During your 5-day trip, 2 days were spent rafting. If the rafting trip covered a distance of 60 miles and you spent 8 hours rafting each day, how many miles did you raft each hour?
Answers
Answer:
3.75 miles per hour
Step-by-step explanation:
Given that:
Number of days spent rafting = 2 days total distance covered during rafting = 60 miles
Time spent rafting per day = 8 hours
Number of miles raft per hour:
Total number of raft hours over the 2 days = (8 * 2) = 16 hours
Total raft distance over the 2 days = 60 miles
Raft miles per hour :
Total raft distance / total number of raft hours
60 miles / 16 hours
= 3.75 miles per hour

Angle TRS would be 180-45x as the angle lies on a straight line and we know angles on a straight line add up to 180 degrees
Then I would add the three angles in the triangle and equate it to 180 degrees as angles in any triangle add up to 180 degrees
therefore:
(180-45x)+25x+(57+x)=180
180-45x+26x+57=180
237-19x= 180
237-180=19x
57=19x
57/19=x
3=x
x is correct as when we substitute it in the angles in the triangle, the interior angles for the triangle does add up to 180

On Thursday a local hamburger shop sold a combined total of 444 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold
Answers
Answer:
148 hamburgers sold
296 cheeseburgers sold
Step-by-step explanation:
x = number of hamburgers sold
2x = number of cheeseburgers sold
444 = total burgers sold
hamburgers + cheeseburgers = total burgers sold
x + 2x = 444
3x = 444
3x/3 = 444/3
x = 148
Check:
148 + 2(148) = 444
148 + 296 = 444
444 = 444
A conservative estimate of the number of stars in the universe is 6x10^22. The average human can see about 3,000 stars at night with his naked eye.About how many more times more stars are there in the universe compared to the stars human can actually see?
Answers
Answer:
2 × 10^19 times
Step-by-step explanation:
Number of stars in universe = 6x10^22
Number of stars eye can see = 3000
About how many more times more stars are there in the universe compared to the stars human can actually see?
Number of stars in universe / number of stars eye can see
= 6x10^22 / 3000
= 6 × 10^22 / 3 × 10^3
= 2 × 10^(22 - 3)
= 2 × 10^19 times
Number of stars in universe is 2 × 10^19 times more than that which the eyes can see

Write a linear equation in slope intercept from that is perpendicular to x−3y=3 and passes through the point (5, −9).
Answers
Answer:
[tex]y=-3x+6[/tex]
Step-by-step explanation:
First, let’s determine the slope of the original equation.
We have [tex]x-3y=3[/tex]
Subtract x from both sides and then divide both sides by -3. So:
[tex]-3y=-x+3\\y=\frac{1}{3}x-1[/tex]
Therefore, the slope of our original line is 1/3.
Remember that perpendicular lines have slopes that are negative reciprocals of each other.
Therefore, the slope of our new perpendicular line is the negative reciprocal of 1/3.
Thus, the slope of our new line will be -3. We flip the fraction and add a negative.
So, the slope of our new line is -3. We also know that it passes through the point (5, -9).
Now, we can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, substitute -3 for m and (5, -9) for (x₁, y₁). This yields:
[tex]y-(-9)=-3(x-5)[/tex]
We want our line in slope-intercept form. So, distribute the right:
[tex]y+9=-3x+15[/tex]
Subtract 9 from both sides. Therefore, our equation is:
[tex]y=-3x+6[/tex]

8 + 2r = −10 what is r?
Answers
Answer:
r = -9
Step-by-step explanation:
Subtract 8 from both sides to get 2r = -18. Divide by 2 on both sides to get r = -9.
Answer:
r=-9
Step-by-step explanation:
Step 1:- Simplify both sides of the equation.
2r+8 = -10
Step 2:- For isolating the variable, subtract 8 from both sides.
2r+8-8 = -10-8
2r = -18
Step 3:- For isolating the variable, divide by 2 from both sides.
2r/2 =-18/2
r= -9

Step-by-step explanation:
To do that, we can set up an equation:
[tex]8x^2-800=0[/tex]
We can divide both sides by 8 to make it easier to solve:
[tex]x^2-100=0[/tex]
Now, isolate the x and take the square root of both sides:
[tex]x^2=100\\x=\pm10[/tex]
Therefore, the 2 zeroes of f(x) are -10 and 10.
