Answer:
Step-by-step explanation:
Actual value: 55 - 21 = 34; estimated value: 55 - 20 = 35.
The difference between the actual and the estimated values of 55 - 21 is 1:
35 - 34 = 1
I think the correct answer is option B. The system of equations given above will have only 1 solution. They will intersect only at 1 point when graphed in a x-y coordinate plane. Hope this answers the question. Please feel free to ask more questions.
Answer:
All integers are rational numbers.
Repeating decimals are not rational numbers.
Terminating decimals are rational numbers.
Step-by-step explanation:
Answer:
z = 5
x = 0
x = 1
Step-by-step explanation:
(z - 5)x^2 - (z - 5)x = 0 Take out z - 5 as a common factor
(z - 5)(x^2 - x) Take out x as a common factor
(z - 5)(x)(x - 1) Any one of these could equal 0. There are 3 solutons.
z - 5 = 0 Add 5 to both sides
z - 5 + 5 = 0 + 5
z = 5
===============
x = 0
===============
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
==============
Hope this helps! Arc CE should be 80.
