Answer:
The two lines are neither parallel nor perpendicular
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope of the line and b is the y intercept of the line
Now, we express the two given equations in this form
We have this as;
7y = x + 5
y = 1/7(x) + 5/7
For the second equation, we have;
y = 7x - 4; this is already expressed
the slope of the first line is 1/7
the slope of the second line is 7
when two lines are parallel, their slopes are equal
when two lines are perpendicular, the product of their slopes is -1
As we can see, both cases does not occur in this system of equations
So, we can conclude that both lines are neither parallel nor perpendicular

what is the equation of the line that passes through the points (4,3) and (6, 2)?
Answers
Answer:
y = -1/2 x + 5
Step-by-step explanation:
1) y = mx + b
2) m is the slope and b is the y-intercept
3) For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form: m = y2 - y1 / x2 - x1
4) Also, let's call the second point you gave, (6,2), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=6 and y2=2.
5) Now, just plug the numbers into the formula for m above, like this: m = -1/2
6) So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this: y = -1/2 x + b
7) To find b, think about what your (x,y) points mean:
(4,3). When x of the line is 4, y of the line must be 3.
(6,2). When x of the line is 6, y of the line must be 2.
8) You can use either (x,y) point you want..the answer will be the same:
(4,3). y=mx+b or 3=-1/2 × 4+b, or solving for b: b=3-(-1/2)(4). b=5.
(6,2). y=mx+b or 2=-1/2 × 6+b, or solving for b: b=2-(-1/2)(6). b=5.
9) So, this means that the equation of the line is y = -1/2 x + 5

x = 95°
y = 147°
z = 128°
Step-by-step explanation:
z = 180 - 52 = 128°
x: first find the remaining angle in the big triangle, 180 - (45 + 50) = 85°
x = 180 - 85 = 95°
y: first find the remaining angle in the small triangle, 180 - (95 + 52) = 33°
y = 180 - 33 = 147°
The leaning tower of pisa in italy has a height of 183 feet and is 4∘ off vertical. find the horizontal distance d that the top of the tower is off vertical. round your answer to the nearest tenth of a foot.

The horizontal distance d that the top of the tower is off vertical is equal to the 190.32feet.
We have given that,
The leaning tower of Pisa in Italy has a height of 183 feet and is 4∘ off vertical.
We have to determine the horizontal distance d that the top of the tower is off vertical. round your answer to the nearest tenth of a foot.
What is the horizontal distance d?
The horizontal displacement of a projectile depends upon the initial horizontal speed and the time of travel. The vertical displacement of a projectile.
The horizontal distance d that the top of the tower is off vertical.
183 times 1.04=190.32.
Therefore the horizontal distance d that the top of the tower is off vertical is equal to the 190.32feet.

The angle of depression of a buoy from a point on a lighthouse 120 feet above the water's surface is 10 degrees. Find the distance from the lighthouse to the buoy. Leave answer with two decimal places.
Answers
Answer:
680. 55 feets
Step-by-step explanation:
From the diagram, distance from lighthouse to buoy = x
Angle from top of lighthouse to buoy = (90 - 10) = 80°
Using the trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = x
Adjacent = 120
Tan 80 = x / 120
5.6712818 = x / 120
x = 5.6712818 * 120
x = 680. 55 feets

Step-by-step explanation:
A) The perimeter is the sum of all of the side lengths.
P = 2(L +W)
P = 2((3d +2) +(d +5)) = 2(4d +7)
P = 8d +14

List the first three wholenumbers greater than 50 that will have a remainder of 7 when you divide by 9/ ?
Answers
Answer:
52, 61 and 70
Step-by-step explanation:
Given
[tex]Divisor = 9[/tex]
[tex]Remainder = 7[/tex]
Required
Determine first 3 possible dividends
The relationship between the [tex]dividend,\ divisor,\ quotient\ and\ remainder[/tex] is:
[tex]Dividend = Divisor * Quotient + Remainder[/tex]
Substitute: [tex]Divisor = 9[/tex] and [tex]Remainder = 7[/tex]
[tex]Dividend = 9* Quotient + 7[/tex]
Since the Dividends must be greater than 50, then the values of the quotient will be 5, 6 and 7
So, we have:
[tex]Dividend = 9* 5 + 7 = 45 + 7 = 52[/tex]
[tex]Dividend = 9* 6 + 7 = 54 + 7 = 61[/tex]
[tex]Dividend = 9* 7 + 7 = 63 + 7 = 70[/tex]
Hence, the three numbers are: 52, 61 and 70
