Amir has spent the last three months saving money for a $1,400 computer in his local electronics store. So far he has saved $1,2

00. Today, he receives an email saying that all computers in the store are 25% off for one day only. If the sales tax charged at the counter is 7%, does Alex have enough money to purchase the computer today?

25% off of $1400 equal: 1400 + .25 = 350, so 1400 - 350 = 1050
So now the computer with 25 % off is $1050.
tax 7%, means 1050 + .07 = $73.50 (sales tax charge)

Total computer with 25% off plus 7% tax equal:

$1050 + 73.50 = $1,123.50

Amir has saved $1200, so he has enough money to purchase the computer.

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.
egoroff_w [7]

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

Ar=W . I

If we know that the area measures 37.8 m^{2} and one side of the figure measures 4.2 m, we can say that:

37.8m^{2}=4.2m. I

We isolate the side we don't know:

\frac{37.8m^{2}}{4.2m} = I\\9 m = I

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

P= I. 2 + W . 2

P= 9m. 2 + 4.2m. 2

P= 26.4 m

Solve y=f(x) for x . f(x)=23x+4 x= Question 2 Find the input when the output is 2. The input is .
Fantom [35]

Let's find f(x) = 2, which is essentially what the problem is asking, what x corresponds to an output of 2.


Let's solve below:

f(x) = 2

  • Setting up what we know

23x + 4 = 2

  • Substituting in 23x + 4 for f(x) (I'm not sure if this is the correct expression for f(x) due to formatting issues)

23x = -2

  • Subtract 4 from both sides to make a step to isolate x (what we are trying to find)

x = - \frac{2}{23}

  • Divide both sides of the equation by 23 to isolate x

Thus the input is \boxed{x = - \frac{2}{23}}.
