X - length of the 3rd side
$10+15>x \wedge 10+x>15 \wedge 15+x>10\\
x5 \wedge x>-5\\
x\in(5,25)$

Sets The table represents a function. What is f(-2)? TITLE TE ♡ ♡ oooo HT

Answer:

can you elaborate more on your question please

if this is the question or similar. An exponential function is given in the form f(x)-a*bx. If f(0)=3 and f(1)=15, what's the value of f(-2)?

this is how to solve it:

f(0) = 3 = a*b0 Therefore 3 = a (1)

f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15

f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15

f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15 b =5

f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15 b =5 a =3 b =5

f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15 b =5 a =3 b =5 f(-2) = 3.5-2 = 3/25

Write (-32)^-2 as an expression without a negative exponent please

Yuliya22 [10]

Step-by-step explanation:

Hey there!

(-32)^-2 Into positive exponents.

We generally law of negative index.

Example;

${x}^{ - y} = \frac{1}{ {x}^{y} }$

So, let's make it same as this:

${ - 32}^{ - 2} = \frac{1}{ { - 32}^{ 2} }$

Hope it helps....

Help,anyone can help me do quetion

a_sh-v [17]

Answer:

B1: x = 51

C1: x = 73, y = 34

Step-by-step explanation:

B1:

By exterior angle theorem:

x° + 54° = 105°

x° = 105° - 54°

x° = 51°

x = 51

x° = 73°(Alternate angles)

x = 73

y° = 34° (corresponding angles)

y = 34
