What is an equation?
The foundation of a regression model based on linearity is the equation y=mx+b. The inclination is B, and the y-intercept is m. Even though y but also y are separate components, the above line is frequently referred as the "mathematical issues with two variables". Two factors make up bivariate linear equations. There are no simple answers for the applications of linear functions. Y=mx+b .
Here,
We can change the second equation into the first equation to find the solution to the system of equations, which results in:
=> x² + (x²-6) = -4
By condensing and rearrangeing, we obtain:
=> 2x² = 2
=> x² = 1
Consequently, x can either be 1 or -1.
We can determine the appropriate values of y by substituting these values of x into either of the two equations:
When x Equals 1:
=> y = x² - 6 = 1 - 6 = -5
When x Equals -1:
=> y = x² - 6 = 1 - 6 = -5
As a result, the system of equations' answers are (-1, -5) and (1, -5).

Answer:
- free throws: 136
- 2-point: 174
- 3-point: 121
Step-by-step explanation:
Let x represent the number of 2-point field goals Rebecca made. Then the number of 3-point field goals can be represented by t, where ...
x = 2t -68 ⇒ t = (x +68)/2 . . . . . number of 3-point field goals
The number of free throws made was x -38.
Rebecca's total point count was ...
1(x -38) +2x +3(x +68)/2 = 847
9/2x +64 = 847
9/2x = 783
x = (2/9)(783) = 174
x -38 = 136
(x +68)/2 = 121
Rebecca made 136 free throws, 174 2-point field goals, 121 3-point field goals.

Answer:
The probability that it is windy, given that it is rainy is:
62.5%≈63%
Step-by-step explanation:
Let A denote the event that it will rain.
B denote the event that it is windy.
A∩B denote the event that it is rainy and windy.
Let P denote the probability of an event.
i.e. we have:
P(A)=0.80
( Since there are 80% chance of rain)
P(A∩B)=0.50
(Since there are 50% chance of wind and rain)
We are asked to find:
P(B|A)
We know that:
Hence, the probability in percent is:
62.5%≈63%

It gives you the formula at the bottom.
The formula is:
Interest = (Principle) x (Rate) x (Time) .
Above that, in the story, it gives you 3 of the 4 quantities in the formula:
Interest = $656
Principle = $1,000
Rate = 4.1% (that's 0.041)
Do you think you could write those numbers into the formula,
and find out what the (Time) is ?
656 = (1,000) x (0.041) x (T)
Divide each side by 41 .
You're welcome.
