Answer:
y=3
Step-by-step explanation:
Answer:
<u>The correct answer is 2. a = 1/2, b = - 3, c = -2</u>
Step-by-step explanation:
1. Let's review the information provided for an answering the question correctly:
0 =1/2x^2- 3x- 2
0 = 1/2x² - 3x - 2
2. Let's find the values for a, b and c.
According to the quadratic equation, we have:
a = 1/2
b = - 3
c = - 2
<u>The correct answer is 2. a = 1/2, b = - 3, c = -2</u>
Answer:
B.) 80 cans, 20 brushes
Step-by-step explanation:
Let the cans of paint be represented by variable <em>p</em> , and brushes by variable <em>b</em>
The first equation would be ; p + b = 100
p = 100 - b
The second equation would be;
8p + 12b = 880
Replace p in the equation by (100-b);
=8(100-b) + 12b =880
=800 - 8b +12b = 880
= subtract 800 from both sides to get;
4b = 880-800
4b = 80
divide both sides by 4 to solve for b;
b= 80/4
b = 20
If p + b = 100, then p+20 = 100
p = 100-20
p = 80
Therefore, they sold 80 cans of paint and 20 brushes
