When x = 0, [tex]\frac{8}{7}[/tex].When y = 2, x = -2.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the function is:
[tex]3x + 7y = 8[/tex]
Placing into standard format:
[tex]7y = 8 - 3x[/tex]
[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]
Hence it is a linear function.
When x = 0:
[tex]y = \frac{8}{7} - \frac{3(0)}{7} = \frac{8}{7}[/tex]
When y = 2:
[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]
[tex]2 = \frac{8}{7} - \frac{3x}{7}[/tex]
[tex]8 - 3x = 14[/tex]
[tex]3x = -6[/tex]
[tex]x = -\frac{6}{3}[/tex]
[tex]x = -2[/tex]

Solve the equation 1/x + 1/3x =4 leave your answer as a fraction in its simplest form
Answer: x = 0.3
Step-by-step explanation:
The required solution of a given equation would be x = 1/3 as a fraction.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
We have been given the equation as
⇒ 1/x + 1/3x = 4
Take the LCM in the above equation
⇒ (3 + 1)/3x = 4
⇒ (4)/3x = 4
Rearrange the term of variable x, and we get
⇒ (4)/(4)(3) = x
⇒ 1/3 = x
⇒ x = 1/3
Therefore, the required solution of a given equation would be x = 1/3 as a fraction.

Caroline purchased a car four years ago at a price of $28,400. According to research on this make and model, similar cars have straight line depreciated to zero value after 8 years. How much will this car be worth after 51 months from when it was purchased?
Answer:
The car value is $13,312.50
Step-by-step explanation:
Trust me this stuff is easy
The car will be worth $13,312.50 after 51 months from when it was purchased.
What is depreciation?Depreciation is the process of deducting the cost of a business asset over a long period of time, rather than over the course of one year.
Now it is given that,
Price of car during purchase = $28,400
Depreciation Time = 8 years
Straight line depreciated value after 8 years = $0
So, Amount of Depreciation per year = Price of car / Depreciaton Time
⇒ Amount of Depreciation per year = 28,400/8
⇒ Amount of Depreciation per year = $3,550
So, after 51 months i.e. 51/12 years
Amount of Depreciation of car after 51 months = Amount of Depreciation per year x Number of years
⇒ Amount of Depreciation of car after 51 months = 3,550 x 51/12
⇒ Amount of Depreciation of car after 51 months = $15,087.5
So, Cost of car after 51 months = $28,400 - $15,087.5
⇒ Cost of car after 51 months = $13,312.50
Thus, the car will be worth $13,312.50 after 51 months from when it was purchased.

Answer:
x > 7
Step-by-step explanation:
i dont know if this is right but i think so
The solution is x > 7
The value of x from the inequality equation 3 ( x - 2 ) > 15 is x > 7
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
3 ( x - 2 ) > 15 be equation (1)
On simplifying the equation , we get
3x - 3 ( 2 ) > 15
3x - 6 > 15
Adding 6 on both sides of the inequality equation , we get
3x > 21
Divide by 3 on both sides of the inequality equation , we get
x > 21/3
x > 7
Therefore , the value of x is greater than 7
Hence , the inequality equation is x > 7

If we reflect the point (-2,3) over the line y=1, what is the new point?
Answer:

Since this is a reflection over the y-axis you'll keep the x-coordinate Making it (-2,?) and then since 3 is two away from y=1 on the plane you'd just count downwards two more giving you -1, so the answer is (-2,-1)
