Points are said to be collinear if they are on the same line. The possible lengths of CD are 31.6cm and 12.6cm

Given that:

CE=22.1cm

DE = 9.5cm

<u>If E is between C and D, then:</u>

CD =CE + DE

So, we have:

CD =22.1cm + 9.5cm

CD =31.6cm

Another possible scenario is:

<u>If D is between C and E, then:</u>

CE = CD + DE

Make CD the subject

CD = CE - DE

So, we have:

CD = 22.1cm -9.5cm

CD = 12.6cm

Hence, the possible values of CD are 31.6cm and 12.6cm

Answer:

The price before tip ,Mrs. Henry's move is 351.9 $

Step-by-step explanation:

Given:

Total bills of 414 $ in which 15 % is tip

To Find:

What is the price before tip,  Mrs. Henry's move

Solution:

Total bill amount is 414$  

And 15 % is tip bill and 85 % is bill before tip

So,

85 % of total bill can give price before tip

OR

calculate 15 % and subtract from total bill.

So 85 % of 414=0.85 *414

=351.9 $

OR

15 % 414=0.15 *414

=62.1 $

Price before Tip is =414$  -62.1 $

=351.9$

So BY Both ways we can get same answer i.e. 351.9 $

Find the slope-intercept form of the lines with the following properties.
Vikentia [17]

Hello!

If you want to find an equation that is parallel to another equation, and passing through the point (1, 4), you need to create a new equation with the same slope, you need to substitute the given point into the new equation to find the y-intercept.

m = 3, y = 3x + b (substitute the ordered pair)

4 = 3(1) + b (simplify)

4 = 3 + b (subtract 3 from both sides)

b = 1

Therefore, the line parallel to the line y = 3x - 2 and passing through the point (1, 4) is y = 3x + 1.
