I really need help with this

Mathematics
1 answer:
Alex Ar [27]3 years ago
5 0

Answer:

A. x = 3, y = -3

B. a = -2, b = 5

C. try your best ill see u later

Step-by-step explanation:

Okay I'mma state some stuff first 3^a + 3^b = 3^(a+b)

and 3^a/3^b = 3^(a-b)

So first equation 3^3*3^-3=3^0

So second equation 3^3/3^-2 = 3^5

So third equation I dont really know the rule but I'mm just plug in a random number for g, like 2, then solve the thing like a normal equation.

So 3^-3 x f^-3 = 12^2 = 144, f^-3 = 144/(3^-3 or 1/27) = 144 x 27 = 3888

so f^-3 = 3888, f = well its an imaginary number according to calculator so u try your best on the last one

If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?
olasank [31]
Direct variation:
y=kx

y=144 when x=12.
144=12k \\ k=\frac{144}{12} \\ k=12

y=? when x=17.
y=12 \times 17 \\
y=204

y=204 when x=17.

The points (a,5) and (9,b) are on the circle x^2+ y^2= 125.
Aneli [31]

Answer:

a = 10

b = 6.633

Step-by-step explanation:

x²+ y²= 125.

In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.

<u>(a,5)</u>

x²+ y²= 125

a² + 5² = 125

a² + 25 = 125

a² = 125-25

a² =  100

a = √100 = 10

(9,b)

x²+ y²= 125

9² + b² = 125

b² 125 - 81

b² = 44

b = √44 = 6.633
