Show the result of substituting x=0 into 0.75x+1.5y=40
prohojiy [21]

Answer:

y=26.67

Step-by-step explanation:

The given equation is 0.75x+1.5y=40.

We need to show the result of substituting x=0 in above equation.

0.75x+1.5y=40

Put x = 0

0.75(0)+1.5y=40

0+1.5y=40

⇒ 1.5y=4

y=\dfrac{40}{1.5}\\\\y=26.67

So, the value of y = 26.67 when x = 0.

"Factoring Quadratic Polynomials into Linear Factors. If x 1 and x 2 are the roots of quadratic polynomial of a x 2 + b x = c (i.e.the root of equation of a x 2 + b x + c = 0 ), then a x 2 + b x + c = a ( x − x 1 ) ( x − x 2 ) .This is the formula of factoring quadratic polynomial into factors."
Hope this helps!!!

When 4 is subtracted from the square of a number, the result is 3 times the number. Find the positive solution
vitfil [10]
Answer is 4 = x. Write out The equation. Then converted to a polynomial. Then use the formula in the top upper right and then do the simple arithmetic to find a positive solution for X. it also makes logical sense as well, 3×4 is 12. I hope this helps and makes sense my Hand writing is not the Best

What is the least common denominator of the expression below? x2 x2 − 16 + 9 + x 8x + 2x2
eduard

The <em>least common</em> denominator of the <em>rational</em> expression [x²/(x² - 16)] + [(9+x)/(8 · x + 2 · x²)] found by factor their denominators is 2 · (x + 4) · (x - 4).

<h3>How to find a least common denominator of a rational equation</h3>

<em>Rational</em> numbers are formed by numbers of the form n/m, where n and m are integers known as numerator and denominator, respectively. The least common denominator is the <em>least</em> denominator between a group of <em>rational</em> functions such that they get the same denominator.

In this case we have two denominators: x² - 16, 8 · x + 2 · x². We can determine the least common denominator by factoring each expression and discovering known terms:

x² - 16 = (x + 4) · (x - 4)

8 · x + 2 · x² = 2 · x · (x + 4)

The <em>least common</em> denominator of the <em>rational</em> expression [x²/(x² - 16)] + [(9+x)/(8 · x + 2 · x²)] found by factor their denominators is 2 · (x + 4) · (x - 4).
