Answer
1.) B
2.) 3 hours
Step-by-step explanation:
1.) option B is correct I think because it shows he will either be equal to or less than how much money he wants to spend
2.) i got three because if you sent up the equal I picked in question one then you subtract 28 from 250 giving u 222 and you divide that by 65 giving you 3.4 but he only charges by the whole hour so that .4 of an hour he wouldn't charge you for
Answer: y = -35x + 105
Step-by-step explanation:
The graph represents a function that is between hours and miles and to determine the equation which belong to this graph, we need to find the slope first by using two points from the graph which are (0, 105) and (3, 0).
The definition of slope is
m = (y2 - y1)/(x2 - x1)
= (0-105)/3-0
= -105/3
= -35
The slope is -35 and remember that the slope is the coefficient of the variable x. Therefore, the answer is:
y = -35x + 105
Answer:
-20 - 90v
Step-by-step explanation:
10(-2-9v) multiply each term in parentheses by 10
-10 × 2 - 10 × 9v multiply the numbers
-20 - 10 × 9v calculate the product
-20 - 90v is the answer
Given,
9(x+1) = 25 + x
expanding,
9x + 1 = 25 + x
bringing x to left hand side and taking 1 to right hand side with change in their respective signs,
9x - x = 25-1
=> 8x = 24
transposing 8 ,
=> x = 24/8 = 3
Hence x = 3
Answer:
x=45
Step-by-step explanation:
You should follow the formula:
3x+3x+x+x=360
8x=360
x=45
