One million = 1000000
Twelve thousand = 12000
Sixty = 60
One million, twelve thousand and sixty = 1 012 060
Standard form is given by A × 10ⁿ
Where A is a number in unit and 'n' is an integer
1 012 060 = 1.012060 × 10⁶
Answer:
B) The data represent a linear function because there is a common difference of -9.
Step-by-step explanation:
A linear function is one in which the difference between consecutive y-values is constant. In this table, to get from one y-value to the next we subtract; this means it is a linear function.
Answer: C 3x + 5y = 1
Solution:
Step 1: To find the equation of line first using both the coordinates given on the graph find the slope using the formula below.
The coordinates are ( -3, 2 ) and ( 2, -1)
m = y2-y1/x2-x1
m = -1-2 / 2- (-3)
m = -3 / 5
Step 2: Now to find line of equation of line we need to find the y intercept using the equation:
y = mx + b
Where
y = y coordinate m = slope x = x coordinate b = y intercept
Choose any one pair of coordinates to find the y intercept. I will be using (2, -1)
y = mx + b
-1 = ( -3 / 5) (2) + b
-1 = -6 / 5 + b ( Don't forget to take the LCM)
-1 = -6/5 + 5b
-5+6 = 5b
1/5 = b
so the equation of line is
y = -3/5 x + 1/5
5y = -3x + 1
3x + 5y = 1
Answer: 5.25 or 5.5 [see note]
Step-by-step explanation:
1/4 (15 – 6) +3 <em><u>[I'm not clear what is meant by the " : 12," so I left it out.]</u></em>
1/4 (9) +3
9/4 + 3
2.25 + 3 = 5.25
===
If it is supposed to read
1/4 (15 – 6) +3/12
Then it would be
5.25 + 0.25 = 5.5
Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.
Your equation should look like:
5h + 20 = 90
Subtract 20 from both sides.
5h = 70
Divide both sides by 5.
h = 14
Gina can rent a surfboard for 14 hours if she has $90.
