Please can anyone solve 9n-10=4n+10
olasank [31]
Yes

remember you can do anything to an equaiton as long as you do it to boh sides
ad try to get unknown to one side
9n-10=4n+10
minus 4n both sides
9n-4n-10=4n-4n+10
5n-10=0+10
add 10
5n+10-10=0+10+10
5n+0=20
5n=20
divide both sies by 5
5n/5=20/5
5/5n=4

HELP<br>8 Prove that 8^6+4^11 is divisible by 17. Answer __*17
Marina CMI [18]

Answer:

<u>262,144</u> goes in the blank

Step-by-step explanation:

8^6 = 262,144

4^11 = 4,194,304

4,194,304 + 262,144 = 4,456,448

4,456,448 ÷ 17 = 262,144

If tan θ = 3/2 and cos θ &lt; 0, use the fundamental identities to evaluate the other five trig functions of θ.
notsponge [240]
Use the Pythagorean theorem, tan is y/x so y = -3 and x= -2. Because cos is negative and R is always positive. You need to find R- which is the hypotenuse;
3^2 + 2^2 = r^2
9 + 4 = r^2
13 = r^2
√13 = r.

So you already have tan<span>θ, 
cot</span><span>θ= 2/3

sin</span>θ= -3/√13 BUT
you have to rationalize, so you get -3 √13/ 13

cscθ= √13/ -3

cosθ= -2/ √13 BUT
you have to rationalize, so you get -2√13/ 13

secθ= √13/ -2

Solve the inequality and sketch the solution on a number line for 3 x &lt; -18​
Snowcat [4.5K]

Answer:

Step-by-step explanation:

Starting with 3 x < -18​, we divide both sides by 3, obtaining x < -6.

Draw a circle centered at x = -6 and then from that circle draw an arrow to the left.
