Answer:

D is not a function

Step-by-step explanation:

To find if a graph is a function draw vertical lines on the graph, if no vertical lines intersect through the graph more than once point then its a function.

Write an equation of the line that is parallel to 5x+20y=10 and passes through the point (8,3).

avanturin [10]

Answer:

20y = -5x + 10

y = -1/4x + 1/2

y - 3 = -1/4(x - 8)

y - 3 = -1/4x + 2

y = -1/4x + 5

Answer:

$\displaystyle \frac{7}{24}$

General Formulas and Concepts:

Algebra I

Exponential Rule [Rewrite]: $\displaystyle b^{-m} = \frac{1}{b^m}$

Calculus

[Area] Limits of Riemann's Sums - Integrals

Integration Rule [Reverse Power Rule]: $\displaystyle \int {x^n} \, dx = \frac{x^{n + 1}}{n + 1} + C$

Integration Rule [Fundamental Theorem of Calculus 1]: $\displaystyle \int\limits^b_a {f(x)} \, dx = F(b) - F(a)$

Step-by-step explanation:

Step 1: Define

$\displaystyle f(x) = \frac{1}{x^4} \\ \ [1, 2]$

Step 2: Find Area

[Integral] Set up area: $\displaystyle \int\limits^2_1 {\frac{1}{x^4}} \, dx$
[Integral] Rewrite: $\displaystyle \int\limits^2_1 {x^{-4}} \, dx$
[Integral] Reverse Power Rule: $\displaystyle \frac{-1}{3x^3} \bigg| \limits^2_1$

Two motorcyclists start at the same point and travel in opposite directions. One travels 10 mph

aleksandrvk [35]

Answer:

The first is traveling at 51 mph.

The second is traveling at 61 mph.

Step-by-step explanation:

$2(x+ 10) + 2x = 224\\2x + 20 + 2x = 224\\4x + 20 = 224\\4x = 204\\x = 51$

The first is traveling at 51 mph.

The second is traveling at 61 mph.

FOR 100 POINTS HELPPPPPPP ASAP

HACTEHA [7]

Answer:

Yes

Step-by-step explanation:

In above image use vertical line test to identify whether a relation is a function or not . Vertical line test means draw various vertical lines in graph and it must cut graph only once i.e. every vertical line must intersect graph only once . if lines intersects graph in more than 1 point than relation is not a function . In short, a relation is a function iff for every value of x there's only one value of y , for any case x has 2 or more than 2 values of y it's not a function.
