Answer:
x=−2
Step-by-step explanation:
Given:
y-intercept of the graph: (0, 90)
zeros: 5 and 9
The equation that models the function based on the zeros given, is either
y = 90 (x-5) (x-9)
or
y= 2(x-5)(x-9)
try solving for the y-intercept of each function,
y = 90 (0-5) (0-9)
y = 4050
(0, 4050)
y = 2(0-5) (0-9)
y = 90
(0, 90)
therefore, the equation that models the function is y = 2(x-5)(x-9)
Answer:
663
Step-by-step explanation:
ratio of Malay = 5
ratio of Indian= 4
ratio of Chinese= 8
Total number of Indian + Chinese= 468
Total ratio= 5+4+8= 17
Let the total number of students= X
Ratio of India= 4/17 × X=
Ratio of Chinese= 8/17 × X=
Addition of ratio of both India and Chinese=
4X/17 + 8X/17= 468
(4X +8X)/17 = 468
12X/17= 468
X= 663
Hence, total number of students is 663
Answer:
Two more cm. ALl you need to do now is convert it to cubic cm because I do not know how to do that.
Step-by-step explanation:
Answer: They are parallel
Step-by-step explanation:
If two lines are parallel , then they must have the same slope and if two lines are perpendicular , the product of their slope must be -1.
To check this , we must calculate the slope of the two lines given.
Slope = 
from the first point
= 2
= 1
= 5
= -1
substituting the values
slope 1 = 1 - 2 / -3 - 5
slope1 = -1 / -8
slope 1 = 1/8
Using the same format to calculate the slope of the second line
= -2
= 0
= -1
= 15
slope 2 = 0 - (-2) / 15 - (-1)
slope 2 = 2/16
slope 2 = 1/8
Since slope 1 = slope 2 , this implies that the lines are parallel
