Answer:

2x + 3y = 10, 3y = 18 (in both cases, for each input x, there is exactly one output y.

Step-by-step explanation:

3y = 10 - 2x, or y = (1/3)(10 - 2x) Yes, this is a function.

4x = 16 → x = 4 NOT a Function, because for x = 4 there are an infinite number of possible y -values

2x - 3 = 14 → 2x = 17 → x = 17/2 Not a function. See reason given above.

3y = 18 → y = 6 Function

2x = 14.6 → x = 7.3 Not a function. See reason given above

Daniel deposits $300 into an account that earns 16% interest annually. Which equation can be used to model his account balance,

MAVERICK [17]

Answer:

$y=300(1+0.16)^x$

Step-by-step explanation:

<h2>This account can be modeled using the compound interest formula.</h2><h2>the compound interest formula is expressed as</h2>

$A= P(1+r )^t$

Where

A =final amount = y

P=initial principal balance = $300

r=interest rate = 16%= 0.16

t=number of time periods elapsed= x

Hence the equation to model his account balance/ final amount A (y) after time (x) years is

$y=300(1+0.16)^x$

The forumla for the volume of a cone is V=1/3pr^2h. the radius r of the caone may be expressed as

xeze [42]

V=1/3hpir^2
times 3 both sides
3V=hpir^2
divide both sides by hpi
$\frac{3V}{h\pi} =r^2$
sqrt both sides
$\sqrt{\frac{3V}{h\pi}} =r$

Given the ABC DEF find the value of x and y

Artemon [7]

Answer: x = 7.2, y = 7.5

<u>Step-by-step explanation:</u>

Similar triangles have the same proportions.

Since ABC ≅ DEF, then $\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}$

<u>Let's solve for x:</u>

$\dfrac{BC}{EF}=\dfrac{AC}{DF}$

⇒ $\dfrac{5}{4}=\dfrac{9}{x}$

⇒ $5(x)=4(9)$

⇒ $x = \dfrac{4(9)}{5}$

⇒ $x = \dfrac{36}{5}$

⇒ $x = 7.2$

<u>Let's solve for y:</u>

$\dfrac{BC}{EF}=\dfrac{AB}{DE}$

⇒ $\dfrac{5}{4}=\dfrac{y}{6}$

⇒ $5(6)=4(y)$

⇒ $\dfrac{5(6)}{4}=y$

⇒ $\dfrac{30}{4}=y$

⇒ $7.5=y$
