Answer:

Option (B)

Step-by-step explanation:

Given system of equations is,

x² + y² = 9 ------(1)

\frac{x^2}{25}-\frac{y^2}{36}=1 -------(2)

From equation (1),

x² = 9 - y²

Substituting these values in equation (2),

\frac{9-y^2}{25}-\frac{y^2}{36}=1

Therefore, Option (B) will be the correct option.

nikitadnepr [17]

Answer:

option c

x + 4 = 64

and

option e

x = 60

Given in the question an expression

3∛x+4 = 12

∛x + 4 = 12/3

∛x + 4 = 4

Take cube on both sides of the equation

∛(x + 4)³ = 4³

x + 4 = 64

x = 64 - 4

x = 60

mixer [17]

Since these are all like terms, you're essentially just adding and subtracting here.

9f + 10f -12f

Add 9f and 10f.

9f + 10f = 19f

Then, subtract.

19f - 12f = 7f

Your answer is 7f.

GIVING BRAINLIEST!<br><br> Solve for y: 3x - y = 14<br><br> Thank you~
ValentinkaMS [17]
To solve y, we need to make y the only value on the left hand side of the equation:

3x - 3x - y = 14 \\  3x - 3x - y = 14 - 3x \\  - y = 14 - 3x \\ y =  - (14 - 3x) \\ y =  - 14 + 3x
Therefore the value of y = -14+3x.

Hope it helps!
