It’s a ratio, so, 40 over the 4 meters is like x over 100 percent

<u>Linear Function</u>

The linear function is widely used to model real situations in life where the dependancy of one variable are linear by nature.

The problem gives us three conditions, more than enough to find a linear model for the earnings for running errands. Let's make x the number of hours it takes to run the errands, and y the earnings. The linear model has the general equation

$y=mx+b$

We have these points (1,20) (2,35) (3,50) and need to find the base fee, which is the value of b or the independant term of the equation.

We'll use the first two points to find the equation and the third point to verify it. Using (1,20)

$20=1\cdot m+b$

$m+b=20$

Now we use (2,35)

$35=m\cdot 2+b$

$2m+b=35$

Subtracting both equations

$m=15$

Replacing into the first equation

$b=5$

The equation is

$y=15x+5$

Let's test the formula by replacing the point x=3

$y=15\cdot 3+5=50$

The model is accurate and the base fee is 5

X^4+2x^2−63 solve by factoring group

Harrizon [31]

The polynomial equation be x⁴ + 2x² - 63 then the factoring group exists ( x² - 7) (x² + 9).

<h3>What is meant by factorization?</h3>

Factorization is the process of dividing a large number into smaller numbers that, when multiplied together, yield the original number. Factorization occurs when you divide a number into its factors or divisors.

Let the given polynomial equation be x⁴ + 2x² - 63

By factoring the above polynomial equation, we get

Here the coefficient of the first term, x⁴, is 1.

The coefficient of the middle term, 2x², is 2.

The final term, "the constant," is -63.

To find -63 factors whose sum equals the middle term's coefficient, which is 2.

-63 + 1 = -62

-21 + 3 = -18

-9 + 7 = -2

-7 + 9 = 2

Split the middle term of the polynomial using the two factors found in step 2 above, -7 and 9 .

x⁴ - 7x² + 9x² - 63.

= ( x² - 7) (x² + 9)

∴ x⁴ + 2x² - 63 = ( x² - 7) (x² + 9) .

The polynomial equation be x⁴ + 2x² - 63 then the factoring group exists (x² - 7) (x² + 9).
