Multiply the average by the number of exams to find total points:
8 x 55 = 440
9 x 60 = 540
The score of the 9th exam is the difference between the two totals:
540 - 440 = 100
They scored a 100
Answer:
The correct option is;
The graph is a line that rises steeply from left to right and passes through the origin
Step-by-step explanation:
The given equation is y = 110·x
Comparing the given equation to the general equation of a straight line, y = m·x + c
Where;
m = The slope of the straight line graph
c = The y-intercept
We have;
The slope of the given equation, y = 110·x = 110
The y-intercept, which is given by the constant c in the given equation = (0, 0)
Therefore, by the slope of the equation, for each unit increase in x, y increases by 110, therefore, the graph is a straight line that rises steeply and passes through the origin
One idea is:
Paul wants to buy an iphone X. He has savings of $100 to start with. Local McDonalds pays $7 per hour (after tax) to students on summer break for helping out at the counter. The iphone costs $1000. At least how many hours does Paul need to work at McDonalds to be able to afford the iphone.
So, that matches ax+b>c in that
a is the hourly earning
b is the initial savings
c is the price of the iphone
27 weeks minimum.
To get this, I divided 520 and 20. It equals 26, but there are still 5 dollars left. She cannot buy the bracelet without them, so you must add on 1 more week.
Good luck!
Answer: 1
Heres why: If you subtract the 1 from 2 you get 1
