The cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.
<h3>Equation</h3>
Plan A:
Manufacturer's recommended list price = 90%
= 90% × 30
= 0.9 × 30
= $27
Total cost of plan A = $30 + $27
= $57
Plan B:
Manufacturer's recommended list price = 70%
= 70% × 90
= 0.7 × 90
= $63
Total cost of plan B = $90 + $63
= $153
Therefore, the cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.

Answer:
.
Step-by-step explanation:
A polynomial is written correctly when the exponents are listed in order from highest to lowest. The highest exponent then dictates the degree of the whole polynomial. The first choice above is written in standard form from highest degree to lowest. Doesn't matter that we might skip the x-squared term or any other x-term, as long as they're in order from highest to lowest. The degree on that first polynomial, the one you're after, is 4 because that's the highest exponent, and there are 4 terms there. Terms are "bunches" of numbers and variables stuck together by multiplication and separated by + or - signs.
Answer:x>7 or x ≤ -3
Solving the 1st inequality
-6x +14 < -28 --------------- (Collect like terms)
-6x < -28 - 14
-6x < - 42 -------------------- (Divide both sides by -6)
Note: If you decide an inequality expression by a negative value, the inequality sign changes)
-6x/-6 > -42/-6
x > 7
Solving the 2nd inequality
9x + 15 ≤ −12 ----------- (Collect like terms)
9x ≤ −12 - 15
9x ≤ −27 ------------------(Divide both sides by 9)
9
9x/9 ≤ −27/9
x ≤ -3
Bring both results together, we get
x>7 or x ≤ -3
The final result is complex (i.e. can't be combined together).
