Answer:

you will know because it you do the system of whatever thingy and there are no two dots in the same row and the line is straight in either a negative or positive slope at a diagonal the equation is linear and its a function.

Step-by-step explanation:

Answer:

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Solve for x −9x+5≤17 OR 13x+25≤−1

arsen [322]

Answer:

(-∞ 2] ∪ [-4/3 ∞ )

Step-by-step explanation:

Given compound inequality,

$-9x+5\leq 17\text{ or }13x+25\leq -1$

$-9x\leq 12\text{ or }13x\leq -26$ ( Subtraction property of inequality )

$-x\leq \frac{12}{9}\text{ or }x\leq -\frac{26}{13}$ ( Division property of inequality )

$-x\leq \frac{4}{3}\text{ or }x\leq -2$

$x\geq -\frac{4}{3}\text{ or }x\leq -2$ ( a < b ⇒ - a > - b )

Hence, the solution of the given inequality is,

(-∞ -2] ∪ [-4/3 ∞ )

Find g(x), where g(x) is the translation 7 units up of f(x)=x2.

AfilCa [17]

Answer:

$g(x)=x^2+7$

$g(x)$ in the form $a(x-h)^2+k$ would be:

$g(x)=(x-0)^2+7$

Step-by-step explanation:

Given:

Parent function:

$f(x)=x^2$

Translation occurs 7 units up to get $g(x)$

Translation Rules:

$f(x)\rightarrow f(x)+c$

If $c>0$ the function shifts $c$ units to the up.

If $c$ the function shifts $c$ units to the down.

So, from the above rules $g(x)$ can be represented as:

$g(x)=f(x)+7$ [7 units up]

$g(x)=x^2+7$

Writing $g(x)$ in the form $a(x-h)^2+k$ where $a, h, and\ k$ are integers.

$g(x)=1(x-0)^2+7$

$g(x)=(x-0)^2+7$

A bicycle tire has a diameter of 62 \text{ cm}62 cm62, start text, space, c, m, end text. What is the distance the bicycle tire

navik [9.2K]

Answer:

The distance bicycle tire travels is <u>1946.8 cm</u>.

Step-by-step explanation:

Given:

Diameter of bicycle tire = 62 cm.

The bicycle tire travels in 10 revolutions.

Now, to find the distance the bicycle tire travels in 10 revolutions.

Diameter = 62 cm.

Radius (r) = $\frac{Diameter}{2}=\frac{62}{2}=31\ cm.$

So, we get the circumference first by putting formula:

$Circumference =2\pi r$

$Circumference =2\times 3.14\times 31\\\\Circumference =194.68\ cm.$

Thus, we get the <u><em>circumference of tire 194.68 cm.</em></u>

<u><em>Number of revolutions the tire travels = 10.</em></u>

Now, to get the distance the bicycle tire travels we multiply circumference of tire by number of revolutions the tire travels:

$194.68\ cm\times 10\\\\=1946.8\ cm.$

Therefore, the distance bicycle tire travels is 1946.8 cm.
