An electronics superstore normally sells a new smartphone for $200, but it is currently offering a 50% discount off the price. The same phone is available online for $200; the website is offering 25% off the phone, plus another 25% discount off all purchases. Where should you buy the phone to get the better deal? Why?

Answers

Answer: They are equal, but if you are buying something else with it,, say a case, the website

Step-by-step explanation:

Website:

1/4 +1/4 = 1/2

Store:

1/2

Answer:

the 50% off is the better deal

Step-by-step explanation:

200 x .50= 100 so on the first phone you save $100

the website you get 25% off so .25 x 200=50 so 200 - 50 =150 then you get another 25% off .25 x 150 =37.50 so 150 - 37.50 = 112.50.

Jason solved the following equation to find the value for x.


–8.5x – 3.5x = –78


x = 6.5


Describe how Jason can check his answer.

Answers

To check his answer, he would put substitute 6.5 for every x in the equation:

-8.75(6.5) - 3.5(6.5) = -78

-56.875 - 22.75 = -78

-79.625 = -78

Because this isn’t true, his answer is wrong

Sample answer:

Substitute the value for x into the original equation. Simplify using order of operations. If the statement is true, Jason’s solution for x is correct. If the statement is false, Jason’s solution for x is incorrect.

Step-by-step explanation: (My answer)

1) Subtract 8.5 and 3.5, that equals 12.

[tex]8.5x - 3.5x = -78[/tex]

2) Multiply 78 and 12, that equals 6.5 .

[tex]\frac{12x}{12} = \frac{78}{12}[/tex]

3) Check your answer.

[tex]-8.5 (6.5) -3.5 (6.5) = -78[/tex]

Multiply 8.5 and 6.5, that equals 55.25. Next, multiply 3.5 and 6.5, that equals 22.75.Finally, you will need to subtract your answers. Subtract both 55.25 and 22.75.

Once you've done that, the answer you should get is 78.

78 is equal to 78, that is your final answer and it is correct.

How to graph an equation?

To graph an equation using the slope and y-intercept. Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). Next, plot the y-intercept. From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

Given data ,

Let the function be f ( x ) = ( 1 / 2 ) x⁵

Now , to know which graph represents the equation mentioned, you can put some values of x in the equation and evaluate the value of y

So , when x = 1

y = ( 1 / 2 )

when x = 2

y = ( 1 / 2 ) × 2⁵

  = 2⁴

  = 16

when x = -1

y= ( 1 / 2 ) × ( -1 )⁵

 = - ( 1 / 2 )

So , by plotting all the points of x and y in the graph , Option a ) satisfies the solution

Hence , the solution is Option a)
