It’s C. Just look at the y-intercepts and it will be fine.
Answer is 6 miles per day
Answer is equation 48 = (x)(5) + 18
Step by step
You can use y intercept equation
y = mx + b
y = 48 total miles
m = rate of miles unknown
x = 5 days
b = starting point of 18 miles already ridden
48 = (x) (5) + 18
48 = 5x + 18
Subtract 18 from both sides to isolate the variable
48 - 18 = 5x + 18 - 18
30 = 5x
Now divide both sides by 5 to solve for x
30/5 = 5/5 x
X = 6 miles per day
Check your work, substitute 6 for x in your equation
48 = (6) (5) + 18
48 = 30 + 18
48 = 48
Problem solved!!
Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289
Step-by-step explanation:
Answer: x = 6
Step-by-step explanation:
Note: I am not 100% sure that this is the correct way to solve this problem. It is just my best attempt to help.
Keep in mind that every percentage can be made into a decimal. 12% = 0.12 because 12% is also 12/100 as a fraction.
Since a percentage is the original number multiplied by the percent, you can solve this problem by dividing the number given by the percent. Be sure to turn the percent into a decimal to make it easier. Your work should look like this:
12% = 0.12
1,000 / 0.12 = 8,333.33
That is the first step. How you have to finish the problem and find what 88% is. To do this, you can simply multiply 88%, or 0.88, times the answer you get in the first part. Your work should look like this:
88% = 0.88
0.88 * 8,333.33 = 7,333.33
Now to check your work, you can add 7,333.33 and 1,000 to see if it equal the total of 8,333.33
7,333.33 + 1,000 = 8,333.3
Since it is equal, this is your answer.
