Answer:
x-intercept = 4
y-intercept = -1
As ordered pairs they would be ( 4, 0) and ( 0, -1)
Step-by-step explanation:
The line goes through 4 on the x line and goes through -1 on the y line.
As an ordered pair you just put the numbers in their x and y spots being ( x, y )
With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and
( 0, -1).

9×9=81
6. There are 24 hours in a day and he spends 0.6 (60%) percent of it studying. You do 24x0.6= 14.4 this means that he spent 14.4 hours studying.
8. A dozen is 12 so you do 8.75x12= 105 for a dozen oranges.
9. 15.5x1.6= 24.8km
10. 1 year is divided into 4 quarters, each quarter is three months because 12 months divided by 4 is 3. That means she paid 18,800 in march since it’s the third month of the year, in another three months she would pay 18,800 again. Every 1 month she pays 6,266 because 18,800 divided by 3 is 6,266. Every 12 months (or year) she pays 75,200 because 18,800x4= 75,200.
11. Every month he makes 8,000 and he saves 0.4 (40%) percent of it each month. 8,000x0.4=3,200 this means he saves 3,200 every month. Multiply 3,200 by 6 months and he saves 19,200 in 6 months.
(Didn’t do 7 and 12 sorry but hope this helped you understand better!)

Answer:
- 4(3a^2 +6a +5)
- a = 3, the numbers are 6, 8, 10
Step-by-step explanation:
1. The sum of squares is ...
(2a)^2 +(2a +2)^2 + (2a +4)^2 = 4a^2 +(4a^2 +8a +4) +(4a^2 +16a +16)
= 12a^2 +24a +20 . . . . . collect terms
= 4(3a^2 +6a +5) . . . . . . factor out 4
__
2. If the sum of the numbers is 24, we have ...
2a +(2a +2) +(2a +4) = 24
6a +6 = 24 . . . . . collect terms
a +1 = 4 . . . . . . . .divide by 6
a = 3 . . . . . . . subtract 1
2a = 6
2a +2 = 8
2a +4 = 10
The numbers are 6, 8, 10.
<em>Check</em>
The sum of squares is ...
4((a +2)(3a) +5) = 4(5(3·3) +5) = 4(50) = 200 . . . . as required
