y ≤ x − 5
y ≥ −x − 4
This is a check and see type of problem.
if x=5
y ≤ 5 − 5 y≤ 0
y ≥ −5 − 4
y ≥-9
-9≤ y ≤ 0
-2 works so (5,-2) is a solution
if x= -5
y ≤ -5 − 5 y≤ -10
y ≥ 5 − 4
y ≥1
no solution
Choice B (5,-2)
First to solve this problem you need to identify a variable to write the inequality.
Let
x = number of points that Carter scores.
The inequality can then be written as:
x> 100
answer:
an inequality to show how may points Carter needs to earn is
x> 100
Answer:
0.09
Step-by-step explanation:
Let x = ages of mother
x : 22 17 27 20 23 19 24 18 19 24
N = 10
Mean = ∑x/N = 218/10 = 21.8
Difference in mean = 21.8 - 20 = 1.8
If significance level = 5% or 0.05
∴ Rejection region = 1.8 X 0.05 = 0.09
Answer:
$4884 to the nearest $.
Step-by-step explanation:
By proportion it is 2275 * (23*28) / (15*20)
= $4884
Well, to find the scale from 7 to 23.1, simply divide 23.1 by 7.
The scale factor for the set is 3.3.
