Which graph correctly represents 3x + y > 7? NEED HELP!!

First rewrite the inequality in y = form.
3x + y > 7
Subtract 3x from both sides.
y > -3x + 7
Both graphs have a -3 slope and y intersect at 7. The only difference in the shading. Choose a test point to see if it makes the inequality true. The easiest point to choose is (0,0) if our line doesn't pass through that point.

0 > -3(0) + 7
0 > 7 is false so we want the graph where (0,0) is NOT shaded. That is the one on the left.

If the blue part is what is shaded, I'd say it's Graph B. But you can double check on a great website called "https://www.desmos.com/"

Answer:

<h2>The answer is option C</h2>

Step-by-step explanation:

<h3> $\frac{ {6}^{ - 3} }{ {6}^{5} }$ </h3>

Using the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's

<h3> $\frac{ {a}^{x} }{ {a}^{y} } = {a}^{x - y}$ </h3>

So we have

<h3> $\frac{ {6}^{ - 3} }{ {6}^{5} } = {6}^{ - 3 - 5} = {6}^{ - 8}$ </h3>

Using the rules of indices

<h3> ${x}^{ - y} = \frac{1}{ {x}^{y} }$ </h3>

So we have the final answer as

<h2> $\frac{1}{ {6}^{8} }$ </h2>

Hope this helps you

Answer:

4.04 metros

Step-by-step explanation:

Resolvemos la pregunta anterior usando la función trigonométrica de

tan θ = Opuesto / Adyacente

θ = 60 °

Frente = 7 metros

Adyacente =? = x

Por eso

bronceado 60 = 7 / x

Multiplicar cruzada

= tan 60 × x = 7

x = 7 / tan 60

x = 4.0414518843 metros

Aproximadamente = 4.04 metros

A machine can stamp 40 envelopes in 8 minutes. How many of these machines, working simultaneously, are required or needed to sta

ziro4ka [17]

Divide 40 by 8 minutes to find the quantity per minute for one machine:

40 / 8 = 5 per minute.

One machine does 5 envelopes per minute.

Now divide 120 by 5 to find the number of machines needed:

120 / 5 = 24

24 machines would be needed.
