Answer:
D=√13(Decimal: 3.605551)
3.6
Step-by-step explanation:
Let's find the distance between your two points.
(−5,5);(−2,3)
(x1,y1)=(−5,5)
(x2,y2)=(−2,3)
Use the distance formula:
D=√(x2−x1[tex])^{2}[/tex]+(y2−y1[tex])^{2}[/tex]
=√(−2−−5[tex])^{2}[/tex]+(3−5[tex])^{2}[/tex]
=√(3[tex])^{2}[/tex]+(−2[tex])^{2}[/tex]
=√9+4
=√13

the sum of the measures of two angles of a triangle is twice the measure of the third angle. the measure of the second angle is 28 degrees less than the measure of the third angle. what is the degree measurement of the largest angle?
9514 1404 393
Answer:
88°
Step-by-step explanation:
If the ratio of the third angle to the sum of the other two is 1 : 2, then the third angle must be 1/(1+2) = 1/3 of the total of angle measures. The third angle is 1/3(180°) = 60°.
If the second angle is 28° less than 60°, then the first angle is ...
180° -60° -(60-28)° = (60 +28) = 88° . . . . . sum of all angles is 180°
The largest angle is 88°.

Step-by-step explanation:
We just need to add up all of the angles, PQT, TQS, and RQS to find the measure of angle PQR.
[tex]PQT=7x+6\\TQS=-2x+8y-13\\RQS=5x+2y\\PQT+TQS+RQS=PQR\\7x+6+TQS+RQS=PQR\\7x+6+(-2x+8y-13)+RQS=PQR\\7x+6+(-2x+8y-13)+5x+2y=PQR\\7x+6-2x+8y-13+5x+2y=PQR\\7x-2x+5x+8y+2y+6-13=PQR\\5x+5x+8y+2y+6-13=PQR\\10x+8y+2y+6-13=PQR\\10x+10y+6-13=PQR\\10x+10y-7=PQR[/tex]

Answer:
123°
Step-by-step explanation:
Each of the parts of the trisected angle is equal to the others.
∠PQT = ∠TQS
7x +6 = -2x +8y -13
9x -8y +19 = 0 . . . . . . subtract the right-side expression
∠TQS = ∠RQS
-2x +8y -13 = 5x +2y
7x -6y +13 = 0 . . . . . . subtract the left-side expression
__
These equations can be solved by any of your favorite methods to give ...
(x, y) = (5, 8)
Then the angle measures are ...
∠PQT = 7x +6 = 7(5) +6 = 41
∠TQS = -2x +8y -13 = -2(5) +8(8) -13 = 64 -23 = 41
∠RQS = 5x +2y = 5(5) +2(8) = 41
The measure of angle PQR is 3·41° = 123°.
_____
Additional comment
Using Cramer's rule, the solution is ...
x = (-8(13) -(-6)(19))/(9(-6) -7(-8)) = 10/2 = 5
y = (19(7) -13(9))/2 = 16/2 = 8
I prefer a method like this, or the graphical solution, when the numbers don't lend themselves to substitution or elimination.

Obviously, once we have found angle PQT, we can simply multiply it by 3 to find angle PQR. We chose to compute the values of the other angles as a check on our math.

PLEASE HELP 70 POINTS
Answer:
-1 = -5
0 = -1
2 = 5
Step-by-step explanation:
In order to do this you need to follow these five (5) steps:
1) Know what each of the variables mean in an equation of a line. The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness of a line and the y-intercept is the point where the line intersects the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)
2) Identify the m (slope) and the b (y-intercept). The slope is 3, which can also be written as 3/1. The y-intercept is -1. (Remember that subtraction of 1 is the SAME thing as adding -1!) Since the y-intercept is a point it will be plotted at (0, -1).
3) Plot the y-intercept first. Start at the origin (intersection of the x- and y-axes) since the x coordinate is 0. Then move DOWN 1 unit since the y-coordinate is negative.
4) Use the m (slope) to plot at least three new points. The slope can also be represented as "rise/run" or the amount of units that you move UP or DOWN (vertically), then LEFT or RIGHT (horizontally). (Remember: if the numerator is positive (move UP); numerator is negative (move DOWN); denominator is POSITIVE (move RIGHT); denominator is NEGATIVE (move LEFT)). Since our slope is 3/1, and both the numerator and denominator are POSITIVE, that means we will be "rising" (moving UP) 3 units and "running" (moving RIGHT) 1 unit.
Start at the y-intercept of (0, -1) and move up 3 units and to the right 1 unit. You should be at (1, 2). Plot a point here. Then do it again. You should now be at (2, 5). Plot another point. Now, do it one more time. You should now be at (3, 8). Plot your last point. (If you wish to continue plotting additional points, feel free to do so.)

f(x) is same as y, plug in x- values to get f(x):
x = - 1 ⇒ f(-1) = 3(-1) - 1 = -3 - 1 = - 4x = 0 ⇒ f(0) = 3(0) - 1 = 0 - 1 = - 1x = 2 ⇒ f(2) = 3(2) - 1 = 6 - 1 = 5Find the equation for the circle with a diameter whose endpoints are (5,-3) and (2,1).
How to solve?
Answer:
Step-by-step explanation:
To write an equation for a circle, we need to find the center and the radius. We need to find the distance between the two endpoints to find the radius. To do that, use the distance formula:
d = √(2 - 5)² + (1 + 3)²
√(-3)² + (4)²
√9 + 16 = √25 = 5
If the diameter is 5, the radius is 2.5
Now we need to find the center/midpoint. Use the midpoint formula:
(5 + 2)/2, (-3 + 1)/2
7/2, -2/2
(3.5, -1)
Now that we have the center and the radius, we can make our equation. Remember that the equation of a circle is: (x - x of center)² + (y - y of center) = radius²
(x - 3.5)² + (y + 1)² = 6.25

Find the equation of the line that passes through the point
(4, 11) and is perpendicular to y= 4/3x + 7
Answer:
y = -3/4x + 14
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal of the original line.
4/3x -> -3/4x
Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].
11 = -3/4(4) + b
11 = -3 + b
14 = b
Put everything we know and solved for back into the expression.
y = -3/4x + 14
