3(2x - 5) - 8x = -2(x - 1)
Use the distributive property:
6x-15 - 8x = -2x +2
Combine like terms:
-2x - 15 = -2x +2
Since both sides have -2x, but the other numbers are not the same, this equation does not have a solution.
The system of inequalities represents the given constraints will be x + y < 20 and 15x + 25y > 375.
<h3>What is inequality?</h3>
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
A nursing student works at a doctor's office for $15 per hour and tutors other students for $25 per hour.
Let x be the number of hours for the doctor's office and y be the number of hours for the tutor.
The student cannot work more than 20 hours each week.
x + y < 20 ...1
15x + 25y > 375 ...2
The system of inequalities represents the given constraints will be x + y < 20 and 15x + 25y > 375.

#SPJ1
They are rational numbers.
Answer:
F (x) = -3x+5x^2+8 has complex roots.
Step-by-step explanation:
number of roots?
ok.
f(x) = 5xx - 3x + 8 = 5xx + 5x - 8x + 8 ( I was guessing what numbers would sum to -3)
nope.
ok try discriminant: (-3)^2 - 4*5 * 8 = 9 - 160 < 0
2 complex roots
Answer:
8 galons
Step-by-step explanation:
line every information by type of units
2 gallons for 750 sq ft
? galons for 3000sq ft
crossmultiply
?*750=2*3000
divide both sides by 750
?=(2*3000) /750= 8
