Answer:

(0,-2)

Step-by-step explanation:

y = 2x-2

This is in the form

y= mx+b where m is the slope and b is the y intercept

y =2x + -2 where 2 is the slope and -2 is the y intercept

Felipe received a $40.00 gift card for a photo center. He used it to buy prints that cost 8 cents each. The remaining balance, B

Neko [114]

For better representation, I think the function is written as:

B(x) = 40.00 - 0.08x

This is much more comprehensive. The variable x represents the number of prints. So, if x=40 prints, we replace this to the x in the equation to find the balance B.

B = 40 - 0.08(40)
<em>B = $36.8</em>

Find the length of segment x. If necessary, round your answer to the nearest tenth (1 decimal place).

sineoko [7]

The length of the segment x is 16.2

Step-by-step explanation:

Here apply the Pythagorean relationship which states that the sum of squares of the sides is equal to the square of the hypotenuse.

Mathematically,

a²+b²=c²

where a=15, b=6, c=r

Hence;

15²+6²=c²

225+36=c²

√261=c

16.16

x⇒16.2

Show that sin (30°) = 1/2

Natali [406]

Answer:

Geometric proof in explanation.

Step-by-step explanation:

Draw an equilateral triangle.

A equilateral triangle has it's sides all congruent and all it's angles measures 60 degrees.

We are going to draw a line segment to cut the equilateral triangles into two congruent right triangles. I will do this in the attachment with p being positive.

You can see we will get 30-60-90 triangles.

We don't need to find the adjacent measurement to the angle whose measurement is 30 degrees since sine is opposite over hypotenuse.

$\sin(30^\circ)=\frac{\frac{p}{2}}{p}=\frac{p}{2} \cdot \frac{1}{p}=\frac{1}{2}$

$\sin(30^\circ)=\frac{1}{2}$
