Wade's grandmother gave him $100 for his birthday. Wade wants to save his money to buy a new MP3 player that cost $275. Each month, he adds $25 to his MP3 savings. Write an equation in slope-intercept form for x, the number of months that it will take Wade to save $275

Answers

Answer:

The answer is:

275 = 25X + 100

Step-by-step explanation:

1.The equation for the slope- intercept is:

y = mx + b

2. Recognize and value variables

x = number of months

y = the expected range to arrive

m = is the amount Wade earns per month

b = the amount of money saved.

3. Solve the equation for X which is the unknown.

275 - 100 = 25X

175 / 25 = X

X = 7

4. . Show the result

275 = 25(7) + 100

275 = 275

5. Wade will take 7 months to buy your MP3 if he saves 25 for each month.

7 months because after the 100 dollars u add u 25 7 times to get 275

1)simplify the expression (2x)^4

2)the perimeter of a rectangular is twice the sum of its length and its width. the perimeter is 16 meters and its length is 2 meters more then twice its width

3)Find the real numbers x and y that make the equation true.

-3 + yi = x + 6i

Answers

$(2x)^4=16x^4$
------------------------------------------
$2(l+w)=16\n l=2w+2\n\n 2(2w+2+w)=16\n 6w+4=16\n 6w=12\n w=2\n\n l=2\cdot2+2\n l=6$
-------------------------------------------
$-3+yi=x+6i\Rightarrow x=-3 \wedge y=6$

For which function is the ordered pair (2, 12) not a solution?y = 6x
y = x + 10
y = 14 - x
y = x - 10

Answers

For the equation y = x - 10 the ordered pair (2,12) is not a solution. The correct option is D.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the ordered pair is (2, 12). The equations will be checked as,

For y = 6x

12 = 6 x 2

12 = 12

For y = x+ 10

12 = 2 + 10

12 = 12

For y = 14 - x,

12 = 14 - 2

12 = 12

For y = x - 10,

12 = 2 - 10 = -8
