Answer:
The first step in solving the equation is "set each binomial factor equal to zero" ⇒ 3
Step-by-step explanation:
To solve a quadratic equation y = ax² + bx + c
- Put y = 0
- Factorize it into two binomial factors (x ± m)(x ± n)
- Equate each binomial factor by 0 to find the values of x
- The values of x are the solution of the equation
∵ The equation is (x + 2)(x - 3) = 0
∵ The equation equated by 0
∵ It is factored into 2 binomial factors (x + 2) and (x - 3)
- The next step is equated each factor by 0 to find the values of x
∴ The 1st step in solving (x + 2)(x - 3) = 0 is set x + 2 = 0 and
x - 3 = 0
The first step in solving the equation is "set each binomial factor equal to zero"
Answer:
$15,000
Step-by-step explanation:
Let the monthly sales = x
We write an expression for each choice. Then we set the choices equal and sole for x.
"monthly salary of $750 plus a bonus of 25% of her monthly sales"
0.25x + 750
"$3000 monthly salary with a 10% bonus on sales"
0.1x + 3000
Set the choice equal:
0.25x + 750 = 0.1x + 3000
0.15x = 2250
x = 2250/0.15
x = 15,000
Answer: $15,000
All the angles required to complete each sentence are:
- m ∠ 4 = 60, m ∠ 2 = 120
- m ∠ 3 = 110, m ∠ 4 = 70
- m ∠ 2 = x, m ∠ 1 = 180 - x
<h3>How to find measures of missing angles by Euclidean geometry</h3>
In this question we must take advantage of definitions and theorems of Euclidean geometry to complete the three sentences seen in the figure. Now we proceed to present each sentence completed in detail:
- If m ∠ 5 = 60, then m ∠ 4 = 60 by <em>alternal internal</em> angles between <em>parallel</em> lines and m ∠ 2 = 120 by <em>supplementary</em> angles.
- If m ∠ 7 = 110, then m ∠ 3 = 110 by <em>corresponding</em> angles between <em>parallel</em> lines and m ∠ 4 = 70 by <em>supplementary</em> angles.
- If m ∠ 6 = x, then m ∠ 2 = x by <em>corresponding</em> angles and m ∠ 1 = 180 - x by <em>supplementary</em> angles.
