Answer: Choice C. y = (-1/2)x+7
=========================================================
Explanation:
The slope of the graphed line is -1/2 because we drop down 1 unit on the y axis each time we move to the right 2 units along the x axis. We could apply the slope formula for any two points on the diagonal line to also get a slope of -1/2.
The slope formula is m = (y2-y1)/(x2-x1).
Any two parallel lines have the same slope, but different y intercepts. So the parallel line will also have slope -1/2. Right away we can see the answer must be choice C. This is the only equation with slope -1/2 of the choices given.
Recall that slope intercept form y = mx+b has m as the slope. Not to be confused with the label m of the graphed line.
Note how plugging x = 6 into the equation for choice C leads to...
y = (-1/2)*x + 7
y = (-1/2)*6 + 7
y = -3 + 7
y = 4
Showing that (x,y) = (6,4) is on the equation y = (-1/2)x + 7. This confirms the answer.
---------------------------
Let's say we didn't have multiple choice answers to pick from, and instead it was fill in the blank. To find the y intercept b, we can do the following
y = mx+b
y = (-1/2)x + b ... plug in given slope m = -1/2
4 = (-1/2)*6 + b .... plug in the given point (x,y) = (6,4)
4 = -3 + b
4+3 = -3+b+3 ... adding 3 to both sides
7 = b
b = 7
Knowing that m = -1/2 and b = 7, we can update y = mx+b into y = (-1/2)x+7

URGENT PLEASE: You purchase a new guitar and take out a loan for $450. You have 18 equal monthly payments of $28 each. What is the simple interest rate for the loan? Round to the nearest tenth of a percent, if necessary.
Answers
8%
Step-by-step explanation:
The amount repaid is ...
A = P(1 +rt)
Filling in the given values, we can find r.
(18·28) = 450(1 +r(18/12)) . . . . . t is in years
504 = 450 + 675t
54/675 = 0.08 = 8%
The simple interest rate on the loan is 8%.
A cube has a volume of 64 cubic meters what is the length of each edge
Answers
Answer:
The length of each side is 4 m
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
64 = s^3
Take the cube root of each side
64 ^ (1/3) = s^3 ^ (1/3)
4 = s
The length of each side is 4 m
Answer: 4 cubic meters
Step-by-step explanation:
The volume of a cube = a³
4³ = 64
So the length of each length has to be 4 cubic meters.

The function f is defined by the following rule f(x) = 5x -5 Complete the function table. -5 -1 I 2 3 4
Answers
Answer:
x f(x)
-5 -30
-1 -10
2 5
3 10
4 15
Step-by-step explanation:
Let us solve the question
∵ The function f is defined by the rule f(x) = 5x - 5
∵ x = -5
→ Substitute x in f by -5 to find the value of f(-5)
∴ f(-5) = 5(-5) - 5 = -25 - 5 = -30
∴ f(-5) = -30
∵ x = -1
→ Substitute x in f by -1 to find the value of f(-1)
∴ f(-1) = 5(-1) - 5 = -5 - 5 = -10
∴ f(-1) = -10
∵ x = 2
→ Substitute x in f by 2 to find the value of f(2)
∴ f(2) = 5(2) - 5 = 10 - 5 = 5
∴ f(2) = 5
∵ x = 3
→ Substitute x in f by 3 to find the value of f(3)
∴ f(3) = 5(3) - 5 = 15 - 5 = 10
∴ f(3) = 10
∵ x = 4
→ Substitute x in f by 4 to find the value of f(4)
∴ f(4) = 5(4) - 5 = 20 - 5 = 15
∴ f(4) = 15

Find the equation of the line through (-1, 3) and (5,3)
Answers
Given:
A line passes through (-1, 3) and (5,3).
To find:
The equation of the line.
Solution:
The line passes through (-1, 3) and (5,3). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{3-3}{5-(-1)}(x-(-1))[/tex]
[tex]y-3=\dfrac{0}{5+1}(x+1)[/tex]
[tex]y-3=0[/tex]
Adding 3 on both sides, we get
[tex]y-3+3=0+3[/tex]
[tex]y=3[/tex]
Therefore, the equation of the line is [tex]y=3[/tex].

the duration of a flash from a camera is timed at 0.004 seconds accurate to 1 / 1000 of a second calculate the upper and lower bounds for the duration of the flash using in quality
Answers
Answer:
0.0035 ≤ x ≤ 0.0045
Step-by-step explanation:
Given that:
The error = 1/1000 = 0.001 / 2 = 0.0005 s
Hence, 0.004 ± Error
0.004 ± 0.0005
Lower boundary = (0.004 - 0.001) = 0.0035
Upper boundary = (0.004 + 0.001) = 0.0045
0.0035 ≤ x ≤ 0.0045
