Answer:

f = 0

Step-by-step explanation:

8 x f = 0               multiply 8 by f

8f= 0                    divide both sides by 8 to get f

8f/8 = 0/8

f = 0

hope this helps! if you have any questions, pls let me know!

Pls help me for brainliest answer
Ket [755]

Answer with Step-by-step explanation:

a)3n + 4 \\  \\n = 1 \\ 3 \times 1 + 4 \\ 3 + 4 \\  =7 \\  \\ n = 2 \\ 3 \times 2 + 4 \\ 6 + 4 \\  = 10 \\  \\ n = 3 \\ 3 \times 3 + 4 \\ 9 + 4 \\  = 13 \\  \\ n = 4 \\ 3 \times 4 + 4 \\ 12 + 4 \\  = 16 \\  \\ n = 10 \\ 3 \times 10 + 4 \\ 30 + 4 \\  = 34 \\

So in this sequence,

1st term = 7

2nd term = 10

3rd term = 13

4th term = 16

10th term = 34

b)4n - 5 \\  \\ n = 1 \\ 4 \times 1 - 5 \\ 4 - 5 \\  =  - 1 \\  \\ n = 2 \\ 4 \times 2 - 5 \\ 8 - 5 \\ =  3 \\  \\ n = 3 \\ 4 \times 3 - 5 \\ 12 - 5 \\  = 7 \\  \\ n = 4 \\ 4 \times 4 - 5 \\ 16- 5 \\  = 11 \\  \\ n = 10 \\ 4 \times 10 - 5 \\ 40 - 5 \\  = 35

In this sequence,

1st term = -1

2nd term = 3

3rd term = 7

4th term = 11

10th term =35

Which equation is a proportion? <br> 1/3= 1/4 <br> 3/4=6/9<br> 5/8=20/32 <br> 7/9=21/28
rosijanka [135]
Well, 1/3 is equal to 0.3, and 1/4 is equal to .25, so it can't be a.
3/4 is equal to .75 and 6/9 is equal to 0.6, so it can't be b.
5/8 is equal to 0.625 and 20/32 is also equal to 0.625, so it could be c.
7/9 is equal to 0.7 and 21/28 is equal to 0.75, so it can't be D.
Your best bet is C. Because both sides of C are equal.
C 5/8=20/32

Please help and explain with these 2 math questions!!!!!!
Volgvan

1)  -10x+y=4

Now, you should substitute x in every situation.

* x=-2 <em>=> -10*(-2)+y=4... 20+y=4... <u>y=-16</u></em>

<em />* x=-1 =>-10*(-1)+y=4... 10+y=4... <u>y=-6</u>

<u />*x=0 => -10*0+y=4... <u>y=4</u>

<u />* x=1 =>  -10*1+y=4... -10+y=4... <u>y=14</u>

<u />* x=2 => -10*2+y=4... -20+y=4... <u>y=24</u>

<u>2)</u> -5x-1=y

For example: x=0

-5*0-1=-1

<u>
