I need to determine which ones are parallel, perpendicular, or neither.
Please help
Answer:
Parallel:
y=3x-7 y=-4x-1 y=1/3x +9 -9x+12y=24 y=x-3
y=3x+1 8x+2y=14 x-3y =3 y=3/4x -5 x-y=8
Perpendicular:
y=-2/5x +3 y=-1/4x 2x+7y=28 y=-5x+1 x+y=7 5x-10y=-20
y=2/5x +8 y=4x-5 7x-2y=4 x-5y=30 x-y=9 y=-2x+6
10x+8y=16
5y=4x-15
Neither:
3x+2y=8 4x+9=18 y=5/3x +7
2x+3y=-12 y=4x+9 6x-10y=10

Convert r= 2 / 7sinθ−cosθ to rectangular form.
Enter your answer in slope-intercept form by filling in the boxes. Enter values so that fractions are simplified.
The rectangular form of the given equation r= 2 / 7sinθ−cosθ which is in polar form is 7x - y = 2 and the slope-intercept form is y = 7x - 2
How to convert from polar form to rectangular form?To convert from polar form to rectangular form we simply take the following steps:
x = rsinθy = rcosθWhat is slope-intercept form?The slope-intercept form is,
y = mx +c
where m is the slope made and c is the intercept both made by the straight line.
In the given question let's first rearrange it,
r × (7sinθ − cosθ) = 2
Multiplying the term (7sinθ−cosθ) with r we get,
7rsinθ - rcosθ = 2
Now we will follow the steps discussed above which is we will put x and y respectively in place of rsinθ and rcosθ.
7x - y = 2
So, the slope-intercept form will be,
y = 7x - 2
Therefore, the rectangular form is 7x - y = 2 and the slope-intercept form is y = 7x - 2.

.Falls
How many
seconds will it
take to fill up
an Olympic
pool with
Victoria Falls
How many seconds will it take to fill up an Olympic pool with Victoria Falls?
The volume of water pouring from Victoria Falls is enough to fill an Olympic swimming pool in around 2.03 seconds.
What is volume?Volume, measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m³), a derived unit, is the SI unit of volume. Volume is another word for capacity.
To find out how many seconds it will take to fill up an Olympic swimming pool with the amount of water falling from Victoria Falls, we need to divide the total amount of water in the pool by the amount of water falling per second:
660,000 gallons ÷ 325,000 gallons/second ≈ 2.03 seconds
Therefore, it would take approximately 2.03 seconds to fill up an Olympic swimming pool with the amount of water falling from Victoria Falls.

somebody please solve this!!!
Answer:
See below.
Step-by-step explanation:
We know that
tanA + tan B
tan (A + B) = ---------------------
1 - tanAtanB
Substituting for A + B
tan (A + B) = tan pi/4 = 1.
tanA + tan B
So ------------------ = 1
1 - tanAtanB
Therefore tanA + tan B = 1 - tanAtanB.

Prove quadrilateral MATH, M (-4,-1) A(-3,2). T(3,0), H(2-3) is a rectangle
Answer:
Since MA ≠ TH, hence MATH is not a rectangle
Step-by-step explanation:
To prove that quadrilateral MATH, M (-4,-1) A(-3,2). T(3,0), H(2-3) is a rectangle, we need to get the length of each sides and show that MA =TH and MH = TA
For MA:
M (-4,-1) A(-3,2)
MA = √(2+1)²+(3+4)²
MA = √(3)²+(7)²
MA = √9+49
MA =√58
For TH:
T(3,0), H(2-3)
TH = √(-3-0)²+(2-3)²
TH = √(-3)²+(-1)²
TH = √9+1
TH =√10
For TH:
M(-4,-1), H(2-3)
MH = √(-3+1)²+(2+4)²
MH = √(-2)²+(6)²
MH = √4+36
MH =√40
For TA:
T(3,0), A(-3,2)
TA = √(2-0)²+(-3-3)²
TA = √(2)²+(-6)²
TA = √4+36
TA =√40
Since MA ≠ TH, hence MATH is not a rectangle

what is 85 divided by 2!!
The result is 85 divided by 2 equals 42.5.
So, when we divide 85 by 2, the quotient is 42, and there is a remainder of 1.
To divide 85 by 2, we need to perform the division operation step by step.
Divide the first digit of the dividend (85) by the divisor (2). The first digit of the dividend is 8.
8 ÷ 2 = 4
Write down the result (4) as the first digit of the quotient.
Multiply the divisor (2) by the quotient digit (4) and subtract the result from the first two digits of the dividend (85).
The result is the remainder.
85 - (2 * 4) = 85 - 8 = 77
Bring down the next digit of the dividend (7) to the remainder (77) to form a new dividend (77).
Divide the first digit of the new dividend (77) by the divisor (2).
77 ÷ 2 = 38 with a remainder of 1
Write down the quotient digit (38) as the second digit of the quotient.
Since there are no more digits to bring down, the division process is complete.
Now, we have the quotient and the remainder:
85 ÷ 2 = 42 with a remainder of 1
i.e. 85 ÷ 2 = 42.5
So, when we divide 85 by 2, the quotient is 42, and there is a remainder of 1.
