Answer:
x=18-2/5y
y=-5/2x+45
Step-by-step explanation:
5x+2y=90
Nosotros queremos resolver para x o y
5x=90-2y
x=18-2/5y
o
2y=90-5x
y=-5/2x+45
Answer:
Unit rate
Step-by-step explanation:
The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.
<h3>What is a number line?</h3>
A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
Next, we would solve the given inequality as follows:
−0.4b + 2.4 < 5.6
Subtracting 2.4 from both sides, we have:
−0.4b + 2.4 - 2.4 < 5.6 - 2.4
−0.4b < 5.6 - 2.4
−0.4b < 3.2
Dividing both sides by -0.4, we have:
b < -3.2/0.4
b < -8
In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.
