slope is the change in y over the change in x.
Using the first and last values:
Slope = (8 - -4)/ (2 - -2)
Slope = 12/4
Slope = 3
Your answer is correct

Given the line: y = -1/5x-3, what is the slope of a line parallel and perpendicular
to the function
Answer:
parallel: m= -1/5
parpendicular: m= 5
Step-by-step explanation:
parallel lines have the same slope
- 1 stays the same so - 1
5 5
parpendicular lines have the opposite reciprocal slope
- 1 flipped is - 5 turn the negative into a positive 5 or 5
5 1 1
Can someone do these problems, thank you :-)
Answer:
Step-by-step explanation:
1) 2^2 + 2^2 = c^2
4 + 4 = c^2
8 = c^2
c = sqrt8
2) 2^2 + 3^2 = c^2
4 + 9 = c^2
13 = c^2
c = sqrt13
3) 10^2 + 4^2 = c^2
100 + 8 = c^2
108 = c^2
c = sqrt108
4) 1^2 + 5^2 = c^2
1 + 25 = c^2
26 = c^2
c = sqrt26
5) 3^2 + 1^2 = c^2
9 + 1 = c^2
10 = c^2
c = sqrt 10
6) 9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
c = sqrt162

Jasmine walks three dogs after school. She brings dog
treats for the dogs. She gives 4 treats to Tucker. Then she splits the
remaining treats between Bogey and Murphy, who get 3 treats each.
How many treats did Jasmine start with? Solve the problem by working
backward, and by writing and solving an equation.
Answer:
if bogey and murphy each get 3 treats and tucker gets 4 then the total is 3+3+4=10
Step-by-step explanation:
Jasmine starts with 10 treats.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
She gives 4 treats to Tucker.
Then splits the remaining treats between Bogey and Murphy, who get 3 treats each.
So, if bogey and murphy each get 3 treats and tucker gets 4 then
= 3+3+4
=10 treats
Hence, at beginning Jasmine starts with 10 treats.

if cos(x) = -1/4 and tan(x) < 0, what is sin(2x)
Answer:
B is correct: (-sqrt15)/8
Step-by-step explanation:
The value of the x is 104.5° then the value of the sin 2x is -0.49. Then the correct option is B.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
If cos(x) = -1/4 and tan(x) < 0
Then the value of the x will be
[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]
Then the value of the sin 2x will be
[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]

JK has endpoints at J(6,-1) and K(-3,-4). If M is the midpoint of JK, approximately what is JM ?
Answer:
midpoint of J and K = (3/2,-5/2) or (1.5,-2.5)
Step-by-step explanation:
midpoint formula: (((x+x1)/2),((y+y1)/2)))
in this case J(x1,y1), and K(x,y) where J = (6,-1), and K = (-3,-4).
so: (((-3+6)/2),((-4+-1)/2))) = (((3)/2),((-5)/2))) = (1.5,-2.5) or (3/2,-5/2)

Find all solutions in the interval [0, 2π).
2 sin^2 x = sin x
Answer:
0, π, 2π, π/6 and 5+(π/6)
Step-by-step explanation:
Rearranging, sinx (2 sinx - 1) = 0.
In [0, 2π],sin x = 0 for x = 0, π and 2π.
The other factor = 0 gives the other two solutions.
sin 5+(π/6) = sin (π−(π-6)) = sin π/6 = 1/2.

Answer:
x= -10
Step-by-step explanation:
simplify 36 - 4.5x + 36 to -4.5x + 72
simplify 102 - 7.5x - 60 to -7.5x + 42
add 7.5x to both sides
simplify -4.5x + 72 + 7.5x to 3x + 72
subtract 72 from both sides
simplify 42 - 72 to -30
divide both sides by 3
simplify 30/3 to 10
Answer: x = -10
