Answer:

y=-3x+3..........(1)

6x+2y=6

putting value of y

6x+2(-3x+3)=6

6x-6x+6=6

o=0

Answer:

45°

Step-by-step explanation:

Segments GJ and HK intersect at F.

That makes angles JFK and GFH vertical angles and congruent.

An arc has the same measure as its central angle.

m<GFH = 45°

m<JFK = m<GFH

m<JFK = 45°

6b^2-13+6=0 Quadratic equations by factoring

alexgriva [62]

Did u mean to write
6b² -13b +6=0
6b² -9b-4b +6 = 0
3b(2b-3) - 2(2b-3)=0
(3b-2)(2b-3)=0
b= 2/3 or 3/2

hope this helps

What is the 4th term in the sequence? <br><br> C(1)=56<br> C(n)= c(n-1)•1/2

Anton [14]

Answer:

The 4th term is 7

Step-by-step explanation:

we have

$C(n)=C(n-1)\frac{1}{2}$

$C(1)=56$

step 1

Find C(2)

For n=2

$C(2)=C(1)\frac{1}{2}$

$C(2)=(56)\frac{1}{2}=28$

step 2

Find C(3)

For n=3

$C(3)=C(2)\frac{1}{2}$

$C(3)=(28)\frac{1}{2}=14$

step 3

Find C(4)

For n=4

$C(4)=C(3)\frac{1}{2}$

$C(4)=(14)\frac{1}{2}=7$

therefore

The 4th term is 7

Let f(x) = xe−x if x ≥ 0 and f(x) = 0 if x < 0<br> Is f a probability density function?

Lynna [10]

Yes. $f(x)$ is a PDF if

• $f(x) \ge 0$ for all $x$ in the support; this is true, since $e^{-x}>0$ for all $x$ , and multiplying a positive number $x$ doesn't change this fact;

• the integral of $f(x)$ over its support is 1; this is also true, since

$\displaystyle \int_{-\infty}^\infty f(x) \, dx = \int_0^\infty xe^{-x} \, dx = 1$

which can be computed by parts.

Do A triangle with sides measuring 12, 16, and 20 is a right triangle?

Julli [10]

Yes, because :
${16}^{2} + {12}^{2} \\ = \sqrt{400} \\ = 20$
