The work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below:
Step 1: 3(2x − 4) = 8 + 2x + 6
Step 2: 5x − 7 = 14 + 2x
Step 3: 5x − 2x = 14 + 7
Step 4: 3x = 21
Step 5: x = 7
In which step did the student first make an error and what is the correct step?
Step 2; 6x − 12 = 14 + 2x
Step 2; 6x − 7 = 2(6 + x + 4)
Step 3; 5x − 2x = 14 − 7
Step 3; 5x + 2x = 14 + 7
Answer:
The student made the error at step 2.
Step-by-step explanation:
The correct step will be:
Step 2; 6x − 12 = 14 + 2x
As 3 will be multiplied with 2x and 4 which will give 6x − 12

The value of a textbook is $120 and decreases at a rate of 12% per year. Write a function to model the situation and then find the value of the textbook after 9 years.
To model the depreciation of a textbook initially worth $120 with a 12% annual decrease, use the function V(t) = 120 x (1 - 0.12)^t. After 9 years, the textbook's value will be approximately $38.24.
The student asks for a function to model the depreciation of a textbook and the value of the textbook after 9 years. The textbook costs $120 initially and depreciates at 12% annually. To model this, we can use an exponential decay function, which is generally of the form V(t) = V_0 imes (1 - r)^t, where V(t) is the value after time t, V_0 is the initial value, r is the rate of decay, and t is time in years.
Plugging in the given values:
V_0 = $120
r = 0.12 (12% as a decimal)
t = 9 years
The function becomes V(t) = 120 imes (1 - 0.12)^t. Now, we find the value of the textbook after 9 years by substituting t with 9:
V(9) = 120 x (1 - 0.12)⁹
Calculate:
V(9) = 120 x (1 - 0.12)⁹
V(9) = 120 x 0.88^9
V(9) =120 x 0.318630...\approx $38.24
Thus, the value of the textbook after 9 years will be approximately $38.24.

The graph shows the shape of an arched bridge cable. What does the y-intercept represent?
The total length of the cable is 15 m.
The left end of the cable is 15 m above the roadway.
The minimum distance between the cable and roadway is 15 m.
The total length of the road is 15 m.
Answer:
The left end of the cable is 15 m above the roadway
Step-by-step explanation:
Let
x----> the horizontal distance from left end of cable (m)
y----> the height above roadway (m)
we know that
The y-intercept is the value of y when the value of x is equal to zero
In this problem
The y-intercept is the height above roadway (m) when the distance from end of cable is equal to zero
so
The y-intercept is the point (0,15)
so
The left end of the cable is 15 m above the roadway
The left end of the cable is 15 m above the roadway]

Which function grows at the fastest rate for increasing values of x?
h(x)=2x
f(x)=4x2+9x
g(x)=18x
Answer:
Option 2. f(x) = 4x² + 9x
Step-by-step explanation:
In this question we have to tell which function grows at the fastest rate for increasing values of x.
1) h(x) = 2x It's a linear function increasing with the value of x.
2). f(x) = 4x²+9x It's a function representing parabola. Moreover the value of the function increases exponentially as the function is in the form of quadratic equation.
3). g(x) = 18x it's again a linear function.
Therefore out of three functions Function 2 will grow at the fastest rate for increasing values of x.
What does the ordered pair (4, 120) represent in context of this problem?
The triangles are similar. What is the value of x?
Answer:
The value of x is [tex]16\ units[/tex]
Step-by-step explanation:
we know that
If two figures are similar , then the ratio of its corresponding sides is equal
In this problem
[tex]\frac{x}{4}=\frac{12}{3}=\frac{20}{5}[/tex]
therefore
[tex]\frac{x}{4}=4[/tex]
[tex]x=16\ units[/tex]

A full waterbed mattress is 7 ft by 4 ft by 1 ft. If water weighs 62.4 lb/ft3, what is the weight of the water in the mattress to the nearest pound?
How can you determine the amount of water the mattress can hold?
The weight of the water is in pounds per cubic feet. How can you get an answer with a unit of pounds?,
The water in the mattress weighs approximately 1,747 pounds.To find the weight of water in the mattress, calculate the volume by multiplying the dimensions and then multiply the volume by the weight of water per cubic foot.
To determine the weight of the water in the mattress, follow these steps:
Calculate the volume of the waterbed mattress by multiplying its dimensions:
Volume = 7 ft * 4 ft * 1 ft = 28 ft³
Next, use the given weight of water per cubic foot to find the total weight:
Weight of Water = Volume * Weight per Cubic Foot
Weight of Water = 28 ft³ * 62.4 lb/ft³
Finally, multiply these values:
Weight of Water = 28 * 62.4 = 1,747.2 lb
To the nearest pound, the weight of the water in the mattress is 1,747 pounds.
define what Skewed Left, and Skewed Right. (Shape of the data)
A left-skewed distribution has a long left tail. This is also called negatively-skewed distributions. That’s for the reason that there is a long tail in the negative direction on the number line. The average is also to the left of the peak.
A right-skewed distribution has a long right tail, or positive-skew distributions. That’s for the reason that there is a long tail in the positive way on the number line. The average is also to the right of the peak.

Find an explicit formula for the arithmetic sequence 37, 74, 111, 148
Let us observe the given series 37,74,111,148
Here, the first term (a) = 37
Common difference(d) = 74-37 = 37
Hence, the given series is in Arithmetic progression.
Hence the nth term of the series is given by:
[tex] a_{n}=a+(n-1)d [/tex]
Substituting the values of 'a' and 'd'.
[tex] a_{n}=37+37(n-1) [/tex]

You can upgrade lighting at your factory to LED bulbs that cost $6.95 each and last an average of 5 years. It costs $3 in labor to change a bulb. Over a 10-year period, about how much will it cost per year to install LED bulbs in 100 lamps and change the bulbs when they burn out?
Answer: $200.00
Step-by-step explanation:
$6.95+ $3.00= $19.90
$19.90 * 100= $1,990
$1,990 / $9.95 = $200.00
take the orginal cost 6.95 plus the $3 labor which equals 19.90 then you multiply by the number of bulbs 100 which equals 1990 then divide 1990 by the cost of bulbs 9.95 which equals 200!
