Which number line shows the inequality n < -3?

Mathematics
1 answer:
madam [21]3 years ago
4 0

Answer: like he dark line represents all the numbers that satisfy x≤2 . If we pick any number on the dark line and plug it in for x, the inequality will be true. The following graph represents the inequality x < 2 . Note that the open circle on 2 shows that 2 is not a solution to x < 2 .

Step-by-step explanation:

in sunlight, a vertical stick has a height of 3ft and casts a shadow 2ft long. at the same time, that a nearby tree casts a shad
Gnoma [55]
30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.

Tell weather the lines for each pair of equations are parallel perpendicular or neither y=-1/5x+6
FinnZ [79.3K]

Answer:

The slopes are neither perpendicular nor parallel.

Step-by-step explanation:

First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.

Solve for y.

-2x + 10y = 5

<u>+2x. =</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+2x</u>

10y = 2x + 5

\begin{gathered} \frac{10y}{10} = \frac{2x + 5}{10} \\ y = \frac{1}{5}x + \frac{1}{2} \end{gathered}

So we now have

\begin{gathered}y = \frac{1}{5}x + \frac{1}{2} \\ and \\ y = -  \frac{1}{5} x + 6 \end{gathered}

Looking at the equation above, the slopes are neither perpendicular nor parallel.

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s0t)(-7)?
Juliette [100K]

Answer:

The answer would be -439

Step-by-step explanation:

To find this, start by finding t(-7)

t(x) = 3x

t(-7) = 3(-7)

t(-7) = -21

Now that we have this answer, we input it into the s(x) equation.

s(x) = 2 - x^2

s(-21) = 2 - (-21)^2

s(-21) = 2 - 441

s(-21) = -439
