Answer:
2 27/32
Step-by-step explanation:
Slope = rise/run
3 down, 1 left: 3/1 = 3
Y = 3x + b
Plug in any point
1 = 3(1) + b, b = -2
Solution: y = 3x - 2
Answer:
d : [ 0 , 26 ]
Step-by-step explanation:
Given:-
- The oranges produced last year, x = 36
- The oranges produced this year, y < 10
Find:-
What are the possible values for how many fewer oranges were produced from the tree this year
Solution:-
- The possible values for how many fewer oranges were produced this year relative to last can be determined by solving an inequality that signifies a difference (d) between last year and this year production as follows:
d = x - y
d = 36 - (<10)
- To remove the inequality from Right hand side we we can shift it to left hand side by inverting the inequality sig, since last production is exactly known we have:
d≥36 - 10
d≥ 26
- So the number of oranges produced are at least 26 less than last year and lower bound would be if there is no orange produced this year. Hence, the range is:
d : [ 0 , 26 ]
Answer:
A = 12.56 m²
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
<u>Geometry</u>
- Area of a Circle: A = πr²
- d = 2r
Step-by-step explanation:
<u>Step 1: Define</u>
d = 4 m
<u>Step 2: Find </u><em><u>r</u></em>
- Substitute: 4 = 2r
- Isolate <em>r</em>: 2 = r
- Rewrite: r = 2 m
<u>Step 3: Find Area</u>
- Substitute: A = π(2)²
- Substitute: A = (3.14)(2)²
- Evaluate: A = (3.14)(4)
- Multiply: A = 12.56 m²
you can work it out or put in random numbers until the two sides are equal
