<span>you have 2 points (0,20) and (10,100) now find the slope using change in y divided by change in x
m=(100-20)/(10-0)
m=80/10
m=8 is the slope</span>

If we plot the given values in the Cartesian plane, the points to which the line would pass are (0, 20) and (10, 100). Thus, the slope m is,
                        m = (y2 - y1) / (x2 - x1)
Substituting,
                         m = (100 - 20) / (10 - 0) = 8
Thus, I saved 8 pesos per week. The answer to the question is letter C.

Use the properties of vertical angles to find the value of x.
Juliette [100K]

Answer:

The value of x= 7 and that of Angle A= 157°

Step-by-step explanation:

(x+16)° = (4x-5)° [Vertically opposite angles]

3x= 21

x= 7

Now, A + (4x-5)° = 180° [Linear pair]

A + [4(7)-5] = 180°

A + 23 = 180°

A = 180° - 23

A = 157°

Hope it helps you

Which of the following expressions represent 15% tip on a $20 meal? Which represents the total bill? **Select all that apply**.
kifflom [539]

Answer:

15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.
