Question 1: The y-intercept is where the line crosses the y-axis. The increments of the y-axis is by 20, and the y-intercept is at (0, 20).

The slope is the change in y over the change in x. Find two points:

(0, 20) and (2, 80)

Now:

(80 - 20)/(2 - 0) = 60/2 = 30

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

So:

y = 30x + 20

Question 2: Again, look for the y-intercept, which is pretty clear. It's (0, 60).

Now find two points:

(0, 60) and (2, 40)

Find the slope:

(40 - 60)/(2 - 0) = -20/2 = -10

So, the equation is:

y = -10x + 60

And, there you go!

What is the measure of the missing angle in the triangle below?
nirvana33 [79]

Answer:

<em>41 degrees</em>

Step-by-step explanation:

<em>According to Angle Sum Property, the sum of the internal angles of a triangle is equal to 180 degrees.</em>

<em>Therefore,</em>

<em>52 + 87 + ? = 180</em>

<em>139 + ? = 180</em>

<em>? = 180 - 139</em>

<em>? = 41 degrees</em>

Solve the equation 3x^2+8=83
skelet666 [1.2K]

Answer:

x = 5

Step-by-step explanation:

3x² + 8 = 83

3x² = 83 - 8

3x² = 75

x² = 75/3

x² = 25

x = √25

x = 5

Please help, whats the right answer?

Answer:

A. 1,485 cubic cm.  B. 27

Step-by-step explanation:

The new prism is dilated by a factor of 3, that means it's made bigger, 3 times bigger on each side.

The dimensions of the new prism are then 12 cm by 7.5 cm by 16.5 cm.

Its volume is then of 12 x 7.5 x 16.5 = 1,485 cubic cm

To answer the second question...

Let's calculate the volume of the original prism:

The original prism's volume was 4 x 2.5 x 5.5 = 55 cubic cm

The new volume is then 1485 / 55 = 27 times bigger than the original.

Which is normal, since we increased each side (dimension) by a factor of 3, so 3x3x3 = 27.
