Answer:

y=2x+8

Step-by-step explanation:

All of the choices are in slope-intercept, or y=mx+b form where m is the slope and b is the y intercept. Therefore if the slope is 2, and the y intercept is 8 the equation should be y=2x+8.

Please help me on this I’m super stuck

erastova [34]

Answer:

Step-by-step explanation:

To solve this you need to know that cosine∅ = adjacent/hypotenuse. We already know that hypotenuse = 5 and that ∅ = 70*. By substituting these in you will get cosine 70* = adjacent/5. Evaluate cosine 70* on the calculator and get 0.633... Multiply both sides by 5 and get adjacent is about equal to 3.1666. Because BC is the adjacent side of the triangle, this is the length of BC.

Identify the perimeter show work

Helen [10]

Answer:

Step-by-step explanation:

The perimeter is the measurement around an object.

So first you multiply the 20 and the 10 by 2.

20 * 2 = 40

10 * 2 = 20

Then, add then up!

40 + 20 = 60

what is the equation in slope intercept form of the line that goes through (2,4) and is perpendicular to the line represented by

Andrej [43]

Answer:

$y = \frac{3x}{2}+1$

Step-by-step explanation:

The slope-intercept form of a straight line equation is y = mx + c, where m is the slope and c is the y-intercept of the line.

Now, we know that if two straight lines are perpendicular to each other then the product of their slopes will be -1.

So, the equation of a straight line which is perpendicular to the line $y = -\frac{2x}{3} +6$ will be $y= \frac{3x}{2}+ c'$ ....... (1), where c' is constant.

Given that the line (1) passes through (2,4) point.

Hence, $4 = \frac{3(2)}{2} +c'$

⇒ c' = 1.

Therefore, the final equation of the required straight line is $y = \frac{3x}{2}+1$ . (Answer)
