- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -x + 1
y = 4x - 14
<u>Step 2: Rewrite Systems</u>
y = 4x - 14
- Multiply everything by -1: -y = -4x + 14
<u>Step 3: Redefine Systems</u>
y = -x + 1
-y = -4x + 14
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 0 = -5x + 15
- Isolate <em>x</em> term: -15 = -5x
- Isolate <em>x</em>: 3 = x
- Rewrite: x = 3
<u>Step 5: Check</u>
- Define equation: y = -x + 1
- Substitute in <em>x</em>: y = -3 + 1
- Add: y = -2
La función que a cada número le asocia su mitad es: f(x)= x/2
Explicación:
La mitad de una cantidad consiste en dividir el total en dos partes iguales, por lo tanto, la función debe representar una división entre el total y 2. Sea x el total, la función sería:
f(x)= x/2
Ejemplos:
La mitad de 20: f(20)= 20/2 = 10
La mitad de 8: f(8)= 8/2 = 4
La mitad de 100: f(100)= 100/2 = 50
La mitad de 2354: f(2354)= 2354/2 =1177

[~Answer~] (8.):
Heyyy. I'm Avery, and I'm always here to help!
I believe the percent may be 15% ($2,400 - 15% = $2,040)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[~Answer Explanation~}:
The percent of the difference is the rate of the difference * 100%
the percent of the difference = .15 * 100% = 15%
since the new price is less than the old price, that is the percent of the decrease.
(See if it'll work): $2,400- 15% = $2,040
And there's your answer <33
