Find the slope of the line passing through the points (-4,7) and (2,-9)

Ira Lisetskai [31]

Answer: The slope is -8/3

Step-by-step explanation: Use the slope formula y2-y1/x2-x1

so -9-7/2-(-4) = -16/6 which can be divided by 2 to get -8/3

Given cos t = 1/2 tan 0 find sin (t) and sec (t)

777dan777 [17]

Answer:

Sin(t) = $\frac{\sqrt{3} }{2} }$ and $sec(t) =2$

Step-by-step explanation:

The secant function is the reciprocal function of the cosine function. Therefore, given that $sec(t) = \frac{1}{cos(t)}$ then, if $cos(t) = \frac{1}{2}$ then $sec(t) =2$ .

On the other hand, if cos (t) = 1/2 ⇒ t = ± $\frac{\pi}{3}$

Then, the sin( $\frac{\pi}{3}$ ) = $\frac{\sqrt{3} }{2} }$

Which equation represents the distributive property?

Arte-miy333 [17]

Answer:

Step-by-step explanation:

Distributive property is when you use the number on the outside of the parenthesis to multiply to the inside. So, 36+9=3(12+3), in order to solve it on the parenthesis side you would take 3 and multiply it by 12, giving you 36. Then, you would take 3 and multiply it to the other 3 which gives you 9.

Which equation represents a line which is parallel to the line y = -x + 5?

ozzi

Answer:

2x + 3y = -21

Step-by-step explanation:

Parallel lines have same slope.

2x + 3y = -21

3y = - 2x - 21

y = $y = \dfrac{-2}{3}x-\dfrac{21}{3}\\\\y=\dfrac{-2}{3}x-7$
