Answer:
Equation 1 = Equation 2
165 - 4x = 145 - 3.50x
Step-by-step explanation:
Let x represent the number of 30-day periods.
Tavon has a gift card for $165 that loses $4 for each 30-day period it is not used.
Therefore the equation =
$165 -$4 × x
= 165 - 4x.......... Equation 1
He has another gift card for $145 that loses $3.50 for each 30-day period it is not used.
$145 -$3.50 × x
= 145 - 3.50x........... Equation 2
Hence, an equation for the number of 30-day periods until the value of the gift cards will be equal is obtained by equating Equation 1 and Equation 2 together
So, we have
Equation 1 = Equation 2
165 - 4x = 145 - 3.50x
We simplify further:
165 - 145 = -3.50 + 4.0x
20 = 0.5x
x = 20/0.5
x = 40
Therefore, number of each 30-day periods until the value of the gift cards will be equal is 40
Answer:
Given that,
The function is,
To find: To find the slope of the secant line from x1=0 and x2=4
Explanation:
First we find the corresponding y values that is y1 and y2 for the given x1 and x2 respectively.
we get,
Whwn x1=0,
When x2=4, we get,
To find the slope of the line passing the points (0,555), (4,1099.8)
we know that,
Slope of the line passing through the points (x1,y1) and (x2,y2)
we get,
Answer is:
Slope of the secant line from x1=0 and x2=4 is 136.2.
Hello!
For the 1st part, you have to find 10% of $24.90
To find percents, change the % to a decimal
10% = 0.1
<em>Now, multiply</em>
0.1 × 24.9 = 2.49
She saved $2.49
To find the new price, subtract the original price with the amount she saved.
Original Price = $24.90
She saved = $2.49
24.90 - 2.49 = 22.41
The new price is $22.41
