Here we are given the inequality:
Let us check for each ordered pair that satisfies the given inequality.
1. (3,0)
LHS: y
here y is 0.
So LHS is 0.
RHS: 4x-5
plugging x as 3,
4(3)-5 = 7
0≥7
False
So (3,0) does not satisfy the inequality.
2. (1,1)
LHS: y
here y is 1.
So LHS is 1.
RHS: 4x-5
plugging x as 1,
4(1)-5 = -1
1≥-1
True
So (1,1) satisfy the inequality.
1. (3,4)
LHS: y
here y is 4.
So LHS is 4.
RHS: 4x-5
plugging x as 3,
4(3)-5 = 7
4≥7
False
So (3,4) does not satisfy the inequality.
1. (2,1)
LHS: y
here y is 1.
So LHS is 1.
RHS: 4x-5
plugging x as 2,
4(2)-5 = 3
2≥3
False
So (2,1) does not satisfy the inequality.
Answer: (1,1) is the solution of the given inequality.
Answer:
A. $66,000
Step-by-step explanation:
The relationship between sales data (in $1,000s) and advertising data (in $100s) is:
If if advertising is $3,000, then x =$30, and the point estimate for sales (in thousands of dollars) is:
Converting it to dollars, the point estimate for sales is:
