A car travels for 6 hours from Los Angeles to San Francisco at a constant speed (v), in miles per hour. Write an equation that can be used to find the speed of the car (v) if it travels for 380 miles.
Answer:
Speed = Distance / Time
Speed of the car = 63.33 miles/ hour (Approx)
Step-by-step explanation:
Given:
Number of hours = 6 hours
Total distance = 380 miles
Find:
Speed of the car
Computation:
Speed = Distance / Time
Speed of the car = 380 / 6
Speed of the car = 63.33 miles/ hour (Approx)

One spring, a group of students measured rainfall
totals at their school. This chart shows how many
inches of rain the students measured each month.
How many more inches did it rain in May than in
April?
MONTH RAINFALL
March 3.9
April 6.9
May 9.4
May have rained 2.5 more inches then in April. First you would need to subtract 9.4 because that’s how much it rained in May and then subtract it with 6.9 because that’s how much it rained in April. Then you get the answer of 2.5. You didn’t have to subtract the March because they didn’t ask you for the inches for the March.

What is Number system?A system of writing numbers is known as a number system. It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set. It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.
Given:
a) 18 is 3 more than 9.
But, 3 more than 9.= 12
So, it is false
b) 18 is 3 times as much as 6.
= 3 x 6
= 18
So, it is true
c) 19 is 3 times as much as 27.
= 3 x 27
= 81
So, it is false
d) 9 is 3 more than 6
= 3+6
= 9
So, it is true

Enter the correct answer in the box. What are the solutions of this quadratic equation?
ײ - 6x= -58
Substitute the values of a and b to complete the sonlutions
x= a+bi
x=a -bi
Answer:
x = 3 + 7i or x = 3 - 7i; a = 3; b = 7
Step-by-step explanation:
x^2 - 6x = -58
We complete the square by adding the square of half of the coefficient of the x-term to both sides.
x^2 - 6x + 9 = -58 + 9
(x - 3)^2 = -49
[tex] x - 3 = \pm 7i [/tex]
x = 3 + 7i or x = 3 - 7i
a = 3; b = 7
The required value of a and b for the solution of the given equation is 3 and 7 respectively.
Given that,
To determine the solutions of this quadratic equation x² - 6x= -58 and Substitute the values of a and b to complete the solution.
x= a+bi
x=a -bi
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Given equation,
x² - 6x= -58
Completing the square of the above equation by adding and subtracting the square of the half of the coefficient of x.
x² - 6x + 9 - 9 = -58
(x - 3)² = -58 + 9
(x - 3)² = -49
x - 3 = √-49
x - 3 = ±7i
x = 3 ±7i
Now,
The required
a + bi = 3 + 7i
a - bi = 3 - 7i
Thus the required value of a and b for the solution of the given equation is 3 and 7 respectively.

A stock valued at $100 decreases in value by 9.5% each year? What is the function?
Answer:
the function is y= 100-0.095x
Step-by-step explanation:
Step one:
given data
A stock valued at $100 decreases in value by 9.5%
let the number of years be x
Step two:
Hence, the rate of decrease is 0.095
therefore the function is
y= 100-0.095x
The function which represents the situation is
[tex]f(x) = 100 - {0.95}^{x} [/tex]
How to write exponential functionoriginal value of stock = $100Percentage decrease per year = 9.5%
= 9.5/100
= 0.095
Number of years = xf(x) = 100 - 0.095^x
[tex]f(x) = 100 - {0.95}^{x} [/tex]
Therefore, the function which represents the situation is f(x) = 100 - 0.095^x

Solve the system by substitution.
y = 3x
y = -4x – 49
Answer:
Step-by-step explanation:
Substitute 3x into y=-4x-49
y=−4x−49
3x=−4x−49
3x+4x=−4x−49+4x(Add 4x to both sides)
7x/7=−49/7
(Divide both sides by 7)
x=−7
Step: Substitute−7forxiny=3x:
y=3x
y=(3)(−7)
y=−21(Simplify both sides of the equation)
Answer:
x=−7 and y=−21
The solution set to the given system of equation is (- 7, - 21).
Differentiate between a mathematical function, equation and expression? Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionExpression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operatorsEquation : A mathematical equation is used to equate two expressions.Given are the system of equations as follows -
y = 3x
y = - 4x - 49
We have the equations as -
y = 3x .... Eq [1]
y = - 4x - 49 .... Eq [2]
Now, we can write the equation [2] as -
3x = - 4x - 49
7x = -49
x = - 7
So, we can find the value of [y] as -
y = 3x
y = 3 x - 7
y = - 21
Therefore, the solution set to the given system of equation is (- 7, - 21).
