Mathematics

Vladimir [108]4 years ago
8 0

Answer:

x = 8  ± 4√3      

Step-by-step explanation:

To solve the quadratic equation, use the inverse operation to squaring. This will undo the exponent and allow x to be isolated. The inverse operation is the square root. This is called the square root property of equality.

(x - 8)² = 48

√(x-8)² = √48

(x - 8) = ±√48

x = 8  ± √48    

x = 8  ± 4√3

The output of a function is 7 more than 3 times the input find the input when the output is -8​
nataly862011 [7]

Answer:

The input is -5 when the output is -8

Step-by-step explanation:

Let

y-----> the output

x ----> the input

we know that

The linear equation that represent this problem is

y=3x+7

so

For y=-8

substitute in the equation and solve for x

-8=3x+7

Subtract 7 both sides

-8-7=3x\\-15=3x

Divide by 3 both sides

x=-5

therefore

The input is -5 when the output is -8

Which method correctly solves the equation using the multiplication property of equality and the reciprocal of One-third? One-th
Airida [17]

Answer:

Step-by-step explanation:

Given the equation \frac{1}{3}(x+9) = -12

Step 1;

Expand the bracket at the right hand side of the equation to have:

\frac{1}{3}x +\frac{1}{3}(9) = -12\\\frac{1}{3}x+3=-12\\subtracting\ 3\ from\ both\ sides\\\frac{1}{3}x+3-3=-12-3\\\frac{1}{3}x=-15\\

Taking the reciprocal of both sides:

\frac{3}{x} = \frac{-1}{15} \\ cross\ multiplying\\-x =45\\x=-45
