Answer:
2/5
Step-by-step explanation:
Let x = numerator
3 + x = denominator
the numerator and denominator are increased by 1 , the fraction becomes
cross multiply
2(x + 1 ) = 4 + x
2x + 2 = 4 + x
combine like terms
2x - x = 4 - 2
x = 2 = numerator
denominator = 2 + 3 = 5
2/5 fraction
20 people are there. Each eat 4 slices of pizza.
Each pizza contains 8 slices.
By forming it as an equation,
20(4) = 8(x pizza)
No of pizzas to be ordered = 10
Answer:
<u><em>What is the importance of polynomial functions?</em></u>
<u><em>
</em></u>Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.

Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
Answer:
y + 6 = (-8/5)(x - 1) in point-slope form
Step-by-step explanation:
Moving from the 1st point to the first, we see that x (the 'run') increases by 5 from -4 to 1, and y (the 'rise') decreases by 8. Thus, the slope of the line through these two points is m = rise / run = -8/5
Now we have two points on the line, plus the slope. Let's write out the point-slope formula for the equation of a straight line:
y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
Here, using the point (1, -6), we obtain:
y + 6 = (-8/5)(x - 1) in point-slope form
Remember that
1m=100cm
8m=800cm
800m=80,000cm
