Can you check my work? I need a little bit of help >.>

So, 14 sentences per minute = 840 sentences per hour (60 minutes in an hour, 14(60)=840)

If 17 pages have 120 sentences on each page, we can conclude that there are a total of 2040 sentences that remain (17x120=2040)

If Jolie can read 840 sentences per hour, we can divide 2040/840 (total # of sentences left divided by sentences per hour)

2040/840 = 2.43 hours.

A) give stating reasons five other angles each equal to x b) prove that AECF is a parallelogram

Gennadij [26K]

Simple Proof:

a) In the image, we know that ABCD is a parallelogram and that means opposite angel measures should be the same. We know that angel DCB is made up by angel 1 and 2, and angel DAB and DCB are equal and angel DAB is made up by angel 1 and x. So now we can conclude that angel x is equal to angel 2.

b) According to the definitions of a parallelogram, opposite angel measures have to be the same, while AECF have angle 1 to angel 1 and angel 2 to angel 1. We can conclude that AECF is NOT a parallelogram. (Sorry, you didn't give me the full question so some information remains unclear. )

WRITE AN EQUATION THAT REPRESENTS THE LINE. USE EXACT NUMBERS.

wel

Answer:

$y=\frac{6}{5}x-5$

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)

1) Determine the slope (m)

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the two given points (0,-5) and (5,1)

$m=\frac{1-(-5)}{5-0}\\m=\frac{1+5}{5-0}\\m=\frac{6}{5}$

Therefore, the slope of the line is $\frac{6}{5}$ . Plug this into $y=mx+b$ :

$y=\frac{6}{5}x+b$

2) Determine the y-intercept (b)

$y=\frac{6}{5}x+b$

On the graph, we can see that when x is 0, y is equal to -5 (we're also given the point (0,-5). Therefore, the y-intercept of the line is -5. Plug this back into the equation:

$y=\frac{6}{5}x-5$

I hope this helps!
