Answer:
B, C
Step-by-step explanation:
I am sure you have heard of the vertical line test. What the vertical line test does is make sure, for every, input, there is only one output. What this means is that two points cannot have the same x, unless they have the same y.
Two different x's can have the same y, but two different y's cannot have the same x.
In this problem, the x's that are taken by other coordinates with different y values are: 1, 3, 4, -4.
This means that the x you are trying to find cannot be any of those since the y value is different than all the other points. Which leaves you with the answers B and C.

Answer:
£1999.85
Step-by-step explanation:
A = P(1 + rt)
Where:
A = Amount after t years
P = Initial amount invested = £1850
r = Interest rate = 2.7%
t = Time in years = 3 years
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.
Solving our equation:
A = £1850(1 + (0.027 × 3))
A = £1999.85
Therefore, Brian will have £1999.85 after 3 years.
Vertical component = 8 x sin(95) = 7.970 (4sf)
Horizontal component = 8 x cos(95) = -0.6972 (4sf)
Answer:
First sencente is the correct one
Step-by-step explanation:
First we can find the total books and the average book per day for each grade:
7th grade: total of 6 + 6 + 7 + 11 + 5 = 35 books
average: 35 / 5 = 7 books per day
8th grade: total of 4 + 5 + 10 + 10 + 16 = 45 books
average: 45 / 5 = 9 books per day
First sencente: true, 8th grade has 9 books per day and 7th grade has 7 books per day
Second sentence: false, 8th grade has 45 books and 7th grade has 35 books
Third sentence: false, it is 6.
Fourth sentence: false, range for 7th grade is 5, range for 8th grade is 12
