Which calculation can be used to find the value of y in the equation y3 = 27

1 answer:

6 0

You just divide each side of the equation by three so you'll get $y = 9$

Edit: I believe you wrote the equation wrongly. If it was $y^3 = 27$ , then you cubic root both sides and get $y = 3$ .

A picture frame is 9 inches long and 6 inches wide. It can display a picture 6 inches long and 4 inches wide. What is the area o

nasty-shy [4]

Area of Frame and Picture
Area = L * W
L = 9
W = 6
Area = 9*6 = 54 in²

Area of Picture
Area = L*W
L = 6
W = 4
Area = 6 * 4
Area = 24 in²

Area of Frame
Area of Frame = Total Area - Picture Area
Area of Frame = 54 - 24
Area of Frame = 30 in²

X^4=15 is an exponential equation?

miskamm [114]

Answer:

No. It is not an Exponential Equation.

Step-by-step explanation:

Given $x^{4} =15$

By the Definition of Exponential Equation which states.

"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."

For Example:

All given below are said to be exponential equations.

$5^{x} =5^{2} \\7^{x}=49\\$

which can be rewritten as

$7^{x}=7^{2}$

Now in the given equation $x^{4}=15$ it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation

1 — 3 (9x + 3) = 3x + 1

Hatshy [7]

Answer: x = -0.3

Step-by-step explanation:

Given expression

1 - 3 (9x + 3) = 3x + 1

Expand parentheses and apply the distributive property

1 - 27x - 9 = 3x + 1

Combine like terms

(1 - 9) - 27x = 3x + 1

-8 - 27x = 3x + 1

Subtract 3x on both sides

-8 - 27x - 3x = 3x + 1 - 3x

-8 - 30x = 1

Add 8 on both sides

-8 - 30x + 8 = 1 + 8

-30x = 9

Divide - 30 on both sides

(-30)x / (-30) = 9 / (-30)

(-30)x / (-30) = 3 / (-10)

$\boxed{x=-0.3}$

Hope this helps!! :)
