Answer:
(- 3, 0) and (- 1, 0)
Step-by-step explanation:
Given
x² + 4x + 3 = 0 ← in standard form
(x + 1)x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x + 3 = 0 ⇒ x = - 3
coordinates of the roots are (- 3, 0) and (- 1, 0)
Answer:
<h3>A. x=5*8</h3>
Step-by-step explanation:
Isolate the term of x from one side of the equation.
<u>First, you have to multiply by 8 from both sides.</u>
<u />
<u>Solve.</u>
<u />
<u>Multiply the numbers from left to right.</u>
5*8=40

Step-by-step explanation:
I think it’s X=1 for answer
X: liters of 15% orange juice
y: liters of 10% orange juice
x+y=5L
y=5L - x
x liters of 15% orange juice plus y liters of 10% orange juice makes 5 liters of 12% orange juice in equation form:
0.15x+0.10y = 0.12(5L)
0.15x+0.10(5L-x)=0.12(5L)
0.15x+0.5-0.10x=0.6
0.05x=0.1L
x=2L
so y = 3L
so you need 2 liters of 15% orange juice and 3 liters of 10% orange juice
