Answer:
"absolute value function," y = |x|
Step-by-step explanation:
This is the graph of the "absolute value function," y = |x|.
Answer:
Step-by-step explanation:
y + 2 = 7(x - 2)
y + 2 = 7x + 14
y = 7x + 12
Answer:
x=1.75 hour
Step-by-step explanation:
200km=2.5
140km=x
2.5 * 140=200x
350=200x
x=350/200
x=1.75
the time it will take is x=1.75 hour
Answer:
22x + 100 = 25x + 70, 10 yards
Step-by-step explanation:
Set the number of square yards of carpeting as x.
So, the cost of Country Carpets is: 22 * x + 100
And the cost of City Carpets is: 25 * x + 70.
In order for the costs to be the , the equations need to be equal.
22x + 100 = 25x + 70
Subtract 22x from both sides.
100 = 3x + 70
Subtract 70 from both sides.
3x = 30
x = 10
10 square yards

Step-by-step explanation:</u></h3>
You could solve this problem by either: Factoring or by using the Quadratic Formula.
SOLVING BY FACTORING STEPS
<em>STEP 1:</em><em> Move (2x−1)(x+1) to the left side of the equation by subtracting it from both sides.</em>
<em />
<em>STEP 2:</em><em> Simplify 2x^2+3x−(2x−1)(x+1).</em>
<em />
<em>STEP 3: </em><em>Simplify each term.</em>
<em />
<em>STEP 4: </em><em>Simplify by adding terms.</em>
<em />
<em>STEP 5:</em><em> Subtract 1 from both sides of the equation.</em>
<em />
<em>STEP 6: </em><em>Divide each term by 2 and simplify.</em>
