Answer:
A) y=1/5x
Step-by-step explanation:
Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5
Now, to check the ans we can multiply the negative reciprocal by "m"
(m in y=mx+c or y=mx+b)
in this case the "m" is stated as 5, so all we need to do is 1/5*5 if the ans is 1 then your ans is right....and over here it is
So thats how you identify & check perpendicular lines!

Step-by-step explanation:
Fran and Alex ride their bicycles from school. Fran rides 3 miles west and 2 miles south to get home. Alex rides 4 miles east and 3 miles north to get home. How many miles apart are Fran's and Alex's homes?
Answer:
The number of miles the homes of Fran's and Alex's homes are apart is approximately 8.602 miles
Step-by-step explanation:
The given displacements, d in vector form are;
For Fran;
3 miles west and 2 miles south gives d₁ = -3·i - 2·j
For Alex;
4 miles east and 3 miles north gives d₂ = 4·i + 3·j
The number of miles apart between Fran's and Alex's homes = d₂ - d₁
d₂ - d₁ = 4·i - (-3·i) + 3·j - (-2·j) = 7·i + 5·j
∴ The number of miles between Fran's and Alex's homes = 7·i + 5·j
The magnitude in miles in the distance between Fran's and Alex's homes = √(7² + 5²) = √74
∴ The magnitude in miles in the distance between Fran's and Alex's homes ≈ 8.602 miles
The magnitude in miles in the distance between Fran's and Alex's homes = The number of miles the homes of Fran's and Alex's homes are apart
∴ The number of miles the homes of Fran's and Alex's homes are apart ≈ 8.602 miles

Step-by-step explanation:
The diagonals of this rhombus are 8 and 16 units long. Their intersection creates four right angles, two 4-unit-long segments, and two 8-unit long segments. Given this information, find the area of the rhombus in square units (Use only the digits 0 – 9 and the decimal point, if needed, to enter a number).
Answer:
[tex]64\ \text{sq. units}[/tex]
Step-by-step explanation:
Area of a rhombus is the product of the length of the diagonals divided by two.
Length of one diagonal is 8 units and the other diagonal is 16 units
Area is given by
[tex]A=\dfrac{8\times 16}{2}\\\Rightarrow A=64\ \text{sq. units}[/tex]
The area of the rhombus is [tex]64\ \text{sq. units}[/tex]
Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.
[tex]A=4\times \dfrac{1}{2}\times 4\times 8\\\Rightarrow A=64\ \text{sq. units}[/tex]

Answer:
x=3
Step-by-step explanation:
3x+4=2x+10
-3 -3
4= -1x+10
-10 -10
-6= -1x
divide by -1
x=6
Thats how you do it
Answer:
x=6
Step-by-step explanation:
first you have to subtract 4 from both sides
3x=2x+10-4
then simplify 2x+10-4 to 2x+6 so you will get
3x=2x+6
-2 -2
(^^you subtract 2x from both sides )
then you get your answer which is x=6

Step-by-step explanation:
It is given that ∠PQR = 130°
∴∠RSP = 130° (vertically opposite angles are equal in a parallelogram)
Round 545 to the nearest hundred
Answer:
500
Step-by-step explanation:
Answer:
500
When rounding to the nearest hundred, like we did with 545 we use these rules
first you would have to round the number up to the nearest hundred if the last two digits in the number are 50 or above.
then you would have to round the number down to the nearest hundred if the last two digits in the number are 49 or below.
lastly you would have to see if the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

What is the vertex of this parabola? y= 2x² + 4x +5
Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )
Eli has a loan of $24,650. This loan has a simple interest rate of 3% per year. What is the amount of interest that Eli will be charged on this loan at the end of two years?
Answer:
$1479
....,..........
Answer:
If your talking about how much they are going to pay ONLY interest for two years then it is $1,479. $1,479 is the amount of money they will be paying for two years ONLY FOR INTEREST.
Step-by-step explanation:
3% of 24,650 is 739.5. That is for one year. 739.5 times 2 for two years is 1,479. Just in interest they will be paying a total of 1479 for two years. Let me know if I'm right. This should be right though. Hope it helped :)

how do you use scientific notation to estimate the hours in a year
Answer:
8.760 x 10^3
Step-by-step explanation:
There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.
