The lines are parallel bc if you change -10x+y=4 into y=10x+4 they will have the same slope of m=10x
Answer:
Option A: 12
Step-by-step explanation:
From the image of the triangle given, we can see that:
XM = ZM
We are given that:
XM = 2x + 2 and ZM = 4x - 8
Thus;
2x + 2 = 4x - 8
Rearrange to get;
4x - 2x = 8 + 2
2x = 10
x = 10/2
x = 5
Thus, XM = 2(5) + 2
XM = 12
Answer:
We choose B. (1, 10)
Step-by-step explanation:
Given the exponential model in the form y = a
- passes through the points (2, 50)
<=> 50 = a
<=> a = (1)
- passes through the points (3, 250)
<=> 250 = a (2)
Substitute (1) into (2) we have:
250 =
<=> 50b = 250
<=> b = 5
=> a = = 2
Hence, our exponential model is: y =2*
Let analyse all possible answer:
A. (0, 5) we have: y =2* ≠ 5 so it is wrong
B. (1, 10) we have: y = 2* so it is true
C. (4, 450) we have: y = 2* ≠ 450 so it is wrong
D. (5, 650) we have: y = 2* ≠ 650 so it is wrong
Hence we choose B. (1, 10)
Mangoes = 4/9 x 180 = 80
Oranges = 5/9 x 180 = 100
Bananas = 3/9 x 180 = 60
Bananas:mangoes:oranges = 3:4:5 = 60:80:100
Total number of fruit = 60 + 80 + 100 = 240
