slope = change in y/change in x.
slope = (4-2)/(7-4)
slope = 2/3.

Which compound inequality is represented by the graph?

OLga [1]

<u>Answer-</u>

$\boxed{\boxed{x < -2\ or\ x \geq 4}}$

<u>Solution-</u>

As we know that, on the number line, if a number is on the right of another number, then the former number is greater than the later number.

As, the number on the right side are 4, 5, ...so on (4 is dotted so it is included)

So the inequality will be $x\geq 4$

As, the number on the left side are -3, -4, -5, ..... so on (-2 is not dotted so it is excluded)

So the inequality will be $x$

Then the compound inequality will be, $x < -2\ or\ x \geq 4$

What IS the slope of a line that is perpendicular to the line y= --x + 5?

Black_prince [1.1K]

<h3>Slopes of perpendicular lines.</h3>

Let k: y = a₁x + b₁ and l: y = a₂x + b₂. Then

We have the line y = -x + 5 ⇒ a₁ = -1.

Therefore

a₂ · (-1) = -1

-a₂ = -1 I<em>change the signs</em>

If tan Θ=3/4, then evaluate 3sin Θ +2cos Θ

Alecsey [184]

Answer:

$3\sin\theta+2\cos\theta=\dfrac{17}{5}$

Step-by-step explanation:

Given that,

The value of $\tan\theta=\dfrac{3}{4}$

We know that, $\tan\theta=\dfrac{\text{perpendicular}}{\text{base}}$

$H^2=B^2+P^2$

H is hypotenuse

$H^2=3^2+4^2\\\\H=5$

$\sin\theta=\dfrac{P}{H}\\\\=\dfrac{3}{5}$

And, $\cos\theta=\dfrac{B}{H}=\dfrac{4}{5}$

So,

$3\sin\theta+2\cos\theta=3\times \dfrac{3}{5}+2\times \dfrac{4}{5}\\\\=\dfrac{9}{5}+\dfrac{8}{5}\\\\=\dfrac{17}{5}$

So, the value is 17/5.
