Answer:
∆PQR: Equilateral Triangle
∆PRT: Scalene Triangle
∆TQS: Isosceles Triangle
∆QNP: Right Triangle
Step-by-step explanation:
∆PQR is an Equilateral Triangle because all of its angles are equal (60°).
∆PRT is a Scalene Triangle because none of its sides are equal.
The triangle above it is equilateral, and one side length is 14, meaning all of its side lengths are 14.
This makes the top of ∆PRT 14. The hypotenuse is given and it’s 18.
The last side left is clearly shorter than both, meaning none of the sides are equal.
∆TQS is an Isosceles Triangle because 2 angles are equal.
The base angles are both 76°.
∆QNP is a Right Triangle because segment QN and PR are perpendicular, creating two 90° angles on both sides.
For number 10, I suggest using a graphing calculator or desmos to graph the points. (Or you can just add the points but I suggest graphing).
From there, you can count the length of each side.
Segment DE: 9
Segment EF: 8
Segment FD: 10
This makes ∆DEF in number 10 a Scalene Triangle because none of its sides are equal.
For number 11, I also suggest graphing the points and counting the sides.
Segment DE: 7
Segment EF: 9
Segment FD: 7
This makes ∆DEF in number 11 an Isosceles Triangle because 2 of its sides are equal.
Hope this helps! :)

Step-by-step explanation:
Answer:
x = 2.66 repeating or 2[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
substitute y for x - 5
y = 2x + 3
x - 5 = 2x + 3
subtract 3 from both sides of the equation
x - 5 - 3 = 2x
x - 8 = 2x
subtract x from both sides of the equation
-8 = 2x - x
-8 = -3x
divide both sides of the equation by -3
-8/-3 = x
2.66 repeating = x
Find the slope of the line
(Please don't answer if you don't know it. It doesn't help at all.)
Answers
The slope is -3. Pick any point on the line. For every 1 unit you move to the right, the "next" point on the line is 3 units down.
You can also use the formula for the slope. According to the graph, the line goes through the points, say, (1, -3) and (3, -9). Then the slope is
slope = (-9 - (-3)) / (3 - 1) = (-9 + 3) / (3 - 1) = -6/2 = -3

a. f1(x) = ln x, f2(x) = ln x^5, (0, [infinity])
b. f1(x) = x^n, f2(x) = x^n + 2, n = 1, 2, \ldots, (−[infinity], [infinity])
c. f1(x) = x, f2(x) = x + 8, (−[infinity], [infinity])
d. f1(x) = cos(x + π), f2(x) = sin x, (−[infinity], [infinity])
Answers
Answer and Step-by-step explanation:
Solution:
(a) The function. f1(x) = ln x, f2(x) = ln x^5 is linearly independent or not.
According to “Linear independent theorem: if two functions f1and f2 are linearly dependent if one can be represent as the constant multiple of other.
f1 = n. f2
Consider given function:
f1(x) = lnx f2(x) = lnx5
(b) Set of function f1(x) = x^n, f2(x) = x^n + 2, is linearly independent or not on the interval [-∞, ∞].
According to “Linear independent theorem: if two functions f1and f2 are linearly dependent if one can be represent as the constant multiple of other.
f1 = n. f2
Consider the given function:
f1(x) = xn f2(x) = xn+2
(c) f1(x) = x, f2(x) = x + 8, (−[infinity], [infinity])
Function is not linearly independent.
Linear independent theorem states that two functions f1 and f2 are linearly dependent if one can represent as the constant multiple of other.
F1= n.f2
(d) f1(x) = cos(x + π), f2(x) = sin x. [-∞, ∞]
According to “Linear independent theorem: if two functions f1and f2 are linearly dependent if one can be represent as the constant multiple of other.
f1 = n. f2

Step-by-step explanation:
You can put the given values for the point ((h, k) = (-5, 2)) and slope (m = -2/5) into the point-slope form of the equation for a line:
y -k = m(x -h)
y -2 = -2/5(x +5)

y = -2/5x
In the diagram g|| h, m<1=(4x+36) and m<2=(3x-3)
What is the measure of <3
Answers
Answer:
60°
Step-by-step explanation:
Since g||h the sum of angle 1 and angle 2 must be equal to 180
4x + 36 + 3x - 3 = 180
7x + 33 = 180
7x = 147
x = 21
The sum of angle 1 and angle 3 is equal to 180 because they are complementary angles
m<1 = 4x + 36 ➡ 4 × 21 + 36 = 120° so angle 3 = 60°

L = (x, y) = (1/5, -7)
Step-by-step explanation:
The given relation tells you ...
(L -J)/(K -L) = 4/1
Cross-multiplying, we have ...
L -J = 4(K -L)
5L = 4K +J . . . . add 4L+J
L = (4K +J)/5
L = (4(1, -10) +(-3, 5))/5 = (4-3, -40+5)/5
