Answer:
y -195 = 15(x -9)$60Step-by-step explanation:
The form of the equation you are given is called "point-slope" form. The "slope" in this case is the per-hour fee. The point is (9 h, $195). Point-slope form generally looks like this:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Here, you have m=15, (h, k) = (9, 195), so the equation looks like ...
y -195 = 15(x -9)
__
The "one-time fee" is the cost when hours are zero.
y -195 = 15(0 -9)
y = 195 -9(15) = 60 . . . . add 195 to both sides, and evaluate
The one-time fee is $60.

Answers
Answer:
A
Step-by-step explanation:
I think because The United States allowed Japan to keep its emperor — Hirohito — after the war. Japan's post-war constitution became official on May 3, 1947, and Japanese citizens elected a new legislature. The U.S. and other allies signed a peace treaty in San Francisco formally ending the war in 1951.
According to Office Of The Historian," The outbreak of the Korean War in 1950 provided SCAP with just the opportunity it needed to address this problem, prompting some occupation officials to suggest that, “Korea came along and saved us.” After the UN entered the Korean War, Japan became the principal supply depot for UN forces. The conflict also placed Japan firmly within the confines of the U.S. defense perimeter in Asia, assuring the Japanese leadership that whatever the state of its military, no real threat would be made against Japanese soil."
Answer: Japan produced supplies for the United States during the Korean War.

is (6,-7) a solution to y+3=1/2(x+2)
Answers
Answer: (4,-2)
To get x substitute 0 for y since you’re trying to find x, 0+3=1/2(x+2) add 0 with 3 to get 3 so 3=1/2(x+2) then use distributive property with 1/2 (x•1/2 = x/2) (2•1/2 = 1) so then the equation would look like this 3=x/2+1 subtract one from both side and get 2=x/2 then multiply everything by 2 to get x=4
With y you can substitute 4 or 0 for x to find your answer

Mr. Barker saved his money for 47 years and had $3,700,028 in the bank. He used his money to go on an adventure and spent $967,300. How much did he have left after his adventure?
Answers
Answer:
The answer is $2,732,728
Step-by-step explanation:
You start subtracting by aligning the numbers by place value. You subtract and get 28 then you have to subtract 0 - 3 which you can’t do and next to it are 2 other 0’s the only number you can carry is 7. You cross out the 7 and put a 6 in its place. The zero next to it becomes a 9. The one next to it also becomes a 9. Then the one on top of the three becomes a 10. You then do 10 - 3. Which equals 7. Then you do 9 - 7 = 2. 9 - 6= 3. You can’t do 6 - 9. so you cross out the 3 make it a 2 and turn the 6 into a 16. 16 - 9 =7. 2 - 0 =2 so then you get. $2,732,728.

An ice cream factory makes 170 quarts of ice cream in 5 hours. How many
quarts could be made in 36 hours? What was that rate per day?
Answers
The amount of quarts which will be made in 36 hours and the production rate per day is :
1224 quarts on 36 hours 816 quarts in a dayGiven the Parameters :
Time taken to make 170 quarts = 36 hours
Number of quarts made in 36 hours using the proportional relationship :
170 = 5
p = 36
Cross multiply :
5p = 170 × 36
5p = 6120
p = 6120 / 5
p = 1224 quarts
The production rate per day :
Number of hours in a day = 24 hours
170 = 5
p = 24
Cross multiply
5p = 170 × 24
5p = 4080
p = 4080/5
p = 816
Therefore, the production rate per day is 816 quarts
