Answer:
=53
Step-by-step explanation:
a=5-b &. a=9+b
combine
5-b=9+b
-4=2b
b= -2
thus, a=7
(-2)^2 + (7)^2
4+49
=53
Answer:
(3,0)
Step-by-step explanation:
put x-3=0 and solve for it whic hwould be x=3
Answer:
No
Step-by-step explanation:
The slope of the equation is y = 2x + 3 is 2.
Find the slope of the points.
m = y₂ - y₁ / x₂ - x₁
m = 1 - 7 / 1 - (-2)
m = -6 / 3
m = -2
The same slope will happen if you also calculate for the third point.
As you can see. The slopes are not the same for one is rising (positive) while the other is fall (negative).
The IQR of the data set is choice C: 9.
To find the IQR, you have to first put the numbers in order.
The order is: 10 12 15 17 19 21 23
The IQR is the difference between the first quartile and the third quartile.
Those values are 12 and 21.
21 - 12 = 9
This is the answer... Hope this is correct.. But the question needs to be clear
