B. y = 45
C. y = 5
D. y = –45
User: 12. Solve this problem: –282 – (+1,017) = ?
A. 1,299
B. –735

D. 735

Answers

Answer 1
Answer: If you would like to solve the equation y/9 + 5 = 0, you can do this using the following steps:

y/9 + 5 = 0
y/9 = -5     /*9
y = -5 * 9
y = - 45

The correct result would be D. y = - 45.


If you would like to solve - 282 - (+ 1,017), you can do this using the following steps:

- 282 - (+ 1,017) = - 282 - 1,017 = - 1,299

The correct result would be C. - 1,299.

Option C:

f(x) = 5x + 7 is the function of the input-output table.

Solution:

Option A: f(x) = 6x + 9

Input x = 1 in the above equation.

f(1) = 6(1) + 9

    = 6 + 9

f(1) = 15

But the output is 12 in the table.

So, it is not the function of the table.

Option B: f(x) = 7x + 5

Input x = 1 in the above equation.

f(1) = 7(1) + 5

f(1) = 12

Input x = 5 in the above equation.

f(5) = 7(5) + 5

f(5) = 40

But the output is 32 in the table.

So, it is not the function of the table.

Option C: f(x) = 5x + 7

Input x = 1 in the above equation.

f(1) = 5(1) + 7

f(1) = 12

Input x = 5 in the above equation.

f(5) = 5(5) + 7

f(5) = 32

Input x = 10 in the above equation.

f(10) = 5(10) + 7

f(10) = 57

Input x = 5 in the above equation.

f(15) = 5(15) + 7

f(15) = 82

All outputs are correct for the given input.

Hence it is the function of the table.

Option D: f(x) = 12x + 1

Input x = 1 in the above equation.

f(1) = 12(1) + 1

f(1) = 12

Input x = 5 in the above equation.

f(5) = 12(5) + 1

f(5) = 61

But the output is 32 in the table.

So, it is not the function of the table.

Hence Option C is the correct answer.

f(x) = 5x + 7 is the function of the input-output table.

Answers

Translate the question into an equation and solve the equation.

108 is 144% of what number?

108 = 144% of x

108 = 144% * x

108 = 1.44x

1.44x = 108

x = 108/1.44

x = 75

Answer: 108 is 144% of 75.
