Step-by-step explanation:

All you need is substarcting the angles

cbf=180-72

cbf=108°

dbe=180-90-72

dbe=18°

abd=90° -right angle.

abc=180-18-90

abc=72

Help please guys thankyouu

You have the right idea so far, but you forgot to finish it up.

Point slope form is

y - y1 = m(x - x1)

where m is the slope, and (x1,y1) is the point the line goes through. As you can see, we have infinitely many choices for (x1,y1). If you use the y intercept point (0,5), then

y - y1 = m(x - x1)

y - 5 = -1(x - 0) ..... this is one of infinitely many possible answers

OR

If you use the point (2,3), then we'd say

y - y1 = m(x - x1)

y - 3 = -1(x - 2) ..... which is another possible answer

There are infinitely many other choices, but I'm only picking the points in which your teacher has shown as big dots.

By the way, nice work on getting the correct answer for the slope-intercept form.

Graph -7x+5y=35. khan acadmy forms of linear equations question. pls show work (10 points)
a_sh-v [17]

Answer:

Below

Step-by-step explanation:

● -7x + 5y = 35

Add 7x to both sides

● -7x +7x + 5y = 35+7x

● 5y = 7x + 35

Divide both sides by 5

● 5y/5 = (7x+35)/5

● y = 1.4x + 7

The graph of the function:

Chang knows one side of a triangle is 13cm which set of two sides is possible for the lengths of the other two sides of this tri
Nikolay [14]
Use the Pythagorean Theorem to check out these possibilities (which you really do need to share here).

Note that 13^2 = 12^2 + 5^2, so 12 and 5 are a possible set of side lengths here.

Wendy borrowed a 370-page book from the library. She's already read 20 pages. The book is due back in 7 days. Write inequality t
quester [9]
There is 350 pages left to read.

350/7 =50

so she had to read 50 pages per day mimum.

so she had to read: greater than, or equal to, 50 pages per day

or < 50 (dont forget the line beneath the greater than sign to make it equal to as well)
