Answer:
The answer to your question is:
Step-by-step explanation:
Data
a)
C (0, 0)
D (7, 12)
m = (12 - 0) / (7 - 0)
m = 12/7
Slope = 12/7
b)
(y - y1) = m(x - x1)
(y - 12) = 12/7 (x - 7)
y - 12 = 12/7 x - 1
y = 12/7 x - 1 + 12
y = 12/7 x + 11
c)
Domain [0, 7]
Range [0, 12]
Answer:
Yes
Step-by-step explanation:
I = 2950
T = 22% x 2950 = 649
CC = 10% x 2950 = 295
NC = 8% x 2950 = 256
R = 1300
I - (T + CC + NC + R) > 0
2950 - ( 649+ 295 + 256 + 1300) > 0
2950 - 2500 >= 0
450 > 0
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
Answer:
Least number of people: 6,240
Greatest number of people: 6760
Step-by-step explanation:
4% of 6500 is 260
6500 - 260 = 6240
6500 + 260 = 6760
"y varies directly with square of x"
y = kx²
where "k" is the constant of variation you need to solve for first.
when y = 100 ; x = 5
100 = k(5)²
100 = 25k
100/25 = k
4 = k
Now you can solve for y when x = 9
y = 4(9)²
y = 4(81)
y = 324
