The line has a slope 5 / 4 and passes through ( − 3, 4 ). What is the equation of the line ? Select one: a. 4x + 5y + 31 = 0 b. 5x − 4y + 31 = 0 c. 4x − 5y + 31 = 0 d. 5x − 4y − 31 = 0
Answers
Answer:
b: 5x-4y+31=0
Step-by-step explanation:
Let's look for an equation of the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
We are given the slope, m, as (5/4), so we can write: y = (5/4)x+b.
To find b, just enter the given point, (-3,4), into the above equation and solve for b:
y=(5/4)x + b
4=(5/4)(-3) + b for (-3,4)
4 = -(15/4)+b
4 + (15/4) = b
4 + (3 3/4) = b
b = 7 3/4
The equation becomes y = (5/4)x + 7 3/4
Also written as: y = (5/4)x + (31/4)
To match this with one of the options, let's multiply by 4 to remove the two fractions:
y = (5/4)x + (31/4)
4y = (5)x + (31)
Rearrange so that the expression is = 0:
4y-5x-31 = 0
Now multiply by -1: -4y+5x+31=0
Rearrange and this will match option b: 5x-4y+31=0

Find the area of triangle XYZ
Answers
Answer:
[tex] \displaystyle A _{XYZ - \text{triangle}} = 24 {cm}^{2} [/tex]
Step-by-step explanation:
we have two right angle triangles
we want to figure out the area of XYZ triangle
we are given the base not the altitude (height) so we need to figure the height of XYZ to figure out the area of XYZ
in that case we can use Pythagoras theorem given by
[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]
given that, c=5 and b=3 thus
substitute:
[tex] \displaystyle {3}^{2} + {a}^{2} = {5}^{2} [/tex]
simplify squares:
[tex] \displaystyle 9 + {a}^{2} = 25[/tex]
cancel 9 from both sides:
[tex] \displaystyle {a}^{2} = 16[/tex]
square root both sides:
[tex] \displaystyle {a}^{} = 4[/tex]
we have figured out the height of XYZ triangle
remember that,
[tex] \displaystyle A _{ \text{triangle}} = \frac{1}{2} bh[/tex]
we have h=4 and b=9+3=12
substitute:
[tex] \displaystyle A _{ \text{triangle}} = \frac{1}{2} \times 12\times 4[/tex]
reduce fraction:
[tex] \displaystyle A _{ \text{triangle}} = 12\times 2[/tex]
simplify multiplication:
[tex] \displaystyle A _{ \text{triangle}} = 24[/tex]
hence,
the area of triangle XYZ is 24 cm²
A car is traveling at a rate of 48 miles per hour. What is the car's rate in miles per minute? How many miles will the car travel in 20 minutes? Do not round your answers.
Will give brainliest. Please Help
Answers
Answer:
Speed of car in miles per minute = 0.8 miles per minute
Distance cover by car in 20 minutes = 16 miles
Step-by-step explanation:
Given:
Speed of car = 48 miles per hour
Time taken by car = 20 minutes
Find:
Speed of car in miles per minute
Distance cover by car in 20 minutes
Computation:
Speed of car = 48 miles per hour
1 hour = 60 minutes
So,
Speed of car = 48/60 miles per minute
Speed of car in miles per minute = 0.8 miles per minute
Distance cover by car in 20 minutes = 20 x Speed of car in miles per minute
Distance cover by car in 20 minutes = 20 x 0.8
Distance cover by car in 20 minutes = 16 miles

If √62-9 =z, what is the value of ?
Answers
The required value of z is "i√6" to the given expression√(6/2 - 9) = z.
What is a complex number?A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, and b are real numbers and i is an imaginary number.
The expression is given in the question, as follows:
√(6/2 - 9) = z
We have to determine the value of z to the given expression.
As per the question, we have
⇒ √(6/2 - 9) = z
⇒ √(3 - 9) = z
⇒ √(- 6) = z
⇒ √(6 × -1 ) = z
⇒ (√6 × √-1 ) = z [∵ imaginary number i = √-1 ]
⇒ (√6 × i ) = z
⇒ z = i√6
Therefore, the required value of z is "i√6" to the given expression.

Eating at the all-you-can-eat buffet at your favorite restaurant currently costs $18.50, and increases in cost by 6% each year.
1. Write a function that correctly depicts this scenario.
2. How much will this buffet cost 10 years from now? Round your answer to the nearest cent.
3. How much did this buffet cost 15 years ago? Round your answer to the nearest cent.
Answers
The function of the scenario is f(x) = 18.5(1.06)^x
The cost 10 years from now is $33.13The cost 15 years ago is $7.72How to determine the function of the scenarioFrom the question, we have the following parameters that can be used in our computation:
Initial value = $18.50
Rate = 6%
The function of the scenario is then represented as
f(x) = Initial value * (1 + rate)^x
Substitute the known values in the above equation, so, we have the following representation
f(x) = 18.5(1 + 6%)^x
Evaluate
f(x) = 18.5(1.06)^x
How much will this buffet cost 10 years from nowThis means that
x = 10
So, we have
f(10) = 18.5(1.06)^10
Evaluate
f(10) = 33.13
How much did this buffet cost 15 years ago?This means that
x = -15
So, we have
f(-15) = 18.5(1.06)^(-15)
Evaluate
f(-15) = 7.72
Hence, the price is $7.72

If AT = 12 and KN = 18, find OB.
Answers
Answer:
15
Step-by-step explanation:
There is a formula for this it is,
B1+B2/2
B1= Base one or TA in this case
B2= Base two or NK in this case
You replace the values with the variable:
B1=12
B2=18
12+18/2 = 30/2= 15
OB=15
The midsegment of the trapezium OB is 15
Mid segment of a trapezium:The midsegment of a trapezoid is parallel to each base, and its length is one-half the sum of the lengths of the bases.
OB = mid segment
Therefore, mathematically,
OB = 1 / 2 (AT + KN)
where
AT = 12
KN = 18

OB = 1 / 2(12 + 18)
OB = 30 / 2

Consequently, the solution of the given question of probability comes out to be P(x<5.67 = 0.63
What is probability?Probability fundamentals. A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
Here,
we use the z-score algorithm to answer this query.
Score Z = x - 40/5
x = the raw score
population mean= μ
Population standard deviation is σ
Hence,
x = 40 μ = 5.67, σ =5
Z = 5.67 - 40/5
z=0.37
Probability based on the Z-Table:
P(x<5.67 = 0.63
Consequently, the solution of the given question of probability comes out to be P(x<5.67 = 0.63 .
