The diagram shows ∆QRS. Which term describes point T?
A. circumcenter
B. Orthocenter
C. Incenter
D. Centroid
Answer:
Step-by-step explanation:
A
The term which describes the point T in triangle QRS is option A. Circumcenter.
Here, given is a triangle QRS.
It is clear that three lines are drawn and all the three lines intersect at the point T.
Each of the line is perpendicular to each of the sides of the triangle.
And each of the line bisects each of the sides, that is sides are being divided in to half.
So T is the intersecting point of all the perpendicular bisectors of the sides, which is the definition of circumcenter.
Thus, T is the circumcenter of the triangle QRS.

12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

What does 100% increase mean
An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial). In other words, the quantity has doubled. An increase of 800% means the final amount is 9 times the original (100% + 800% = 900% = 9 times as large).

HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.
Answer:
175ft an hour
Step-by-step explanation: lets say t=hours
so 2t=400ft and 6t=700ft
the difference between hours is 4 because 6-4=2
so we would multiply 4 by ?
to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
Answer:
total distance =700+400ft
time =2+8 =10hour
rate =distance/time=1100/10=110 ft/hour
since he stops two times
rate of change =110/2=75ft/hour

Let's solve your equation step-by-step.
2x+9=8x+21
Step 1: Subtract 8x from both sides.
2x+9−8x=8x+21−8x
−6x+9=21
Step 2: Subtract 9 from both sides.
−6x+9−9=21−9
−6x=12
Step 3: Divide both sides by -6.
-6x/-6=12/-6
x=-2
Answer:
-2 = x
Step-by-step explanation:
First, combine like-terms. I subtracted 21 from both sides and subtracted 2x from both sides. This gave us 12 = -6x. Then, divide to solve for x. This gives us -2 = x.

 Write an equation in slope intercept form of the line shown. (4,1) (8,4)
Answer:
Y = 3/4x - 2
Step-by-step explanation:
Slope (rise/run) is 3/4 and the y-intercept is -2.
Hope this helps. Pls give brainliest.
An equation in slope intercept form of the line shown (4,1) and (8,4) is y=3/4 x-2.
The given coordinate points are (4, 1) and (8, 4).
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Here, slope = (y2-y1)/(x2-x1)
= (4-1)/(8-4)
= 3/4
Put m=3/4 and (x,y)=(4,1) in y=mx+c
1=3/4 (4)+c
⇒c=-2
Now, substitute m=3/4 and c=-2 in y=mx+c and simplify
That is y=3/4 x-2
Therefore, an equation in slope intercept form of the line shown (4,1) and (8,4) is y=3/4 x-2.
