Answer:

Step-by-step explanation:

To answer this problem, work backwards!

The question said that 7 is subtracted from a number 4 times. The opposite of this is to add 7 four times.

7 + 7 + 7 + 7 = 28

The problem also says that the result is 3. That means that after subtracting 7 four times, the remainder is 3. Let's add that remainder to our sum (or the answer to an addition problem.)

28 + 3 = 31

Therefore, the number is 31.

Check your work:

Let's subtract 7 from 31 four times.

31 - 7 = 24

24 - 7 = 17

17 - 7 = 10

10 - 7 = 3

After we subtracted 7 four times, the result was 3. That means our answer is correct!

The equation of the graph shown plotted in the coordinate plane is y = x + 4. What statement is not true about this graph? A. Ea
frez [133]

Definately option C

  • As it's mentioned y=x+4 it must be function
  • So in function every domain has its unique range.
  • Hence here the slope is not constant

As

The graph shown is a parabola which is not y=x+4

So option C is wrong

Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below:
Ksenya-84 [330]
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47. 

In its current order the answer would be 28.

Can someone help me with math? I DO NEED help with questions 13, 11, 9, 8, 7, 5, 3. PLEASE HELP ME!!!!! I need these answered by

Absolute value is just how many integers rhat number is away from 0. i say this because it’s not too hard of a thing to learn and it’s very important in the higher grades.

3 is 2 6/7
5 is a greater than symbol >
7 is 1/3 and negative 1/3 so -1/3
8 is 14 and -14
9 is 21 and -21
11 is | -75 |
i’m not sure about 13 but i believe it could be | -8 |
i hope this helped

Line FG contains points F (3,7) and G (-4,-5) line HI contains points (-1,0) and I (4,6) lines FG and HI are. ?
ludmilkaskok [199]
FG : (3,7)(-4,-5)
slope = (-5 - 7) / (-4-3) = -12/-7 = 12/7

y = mx + b
slope(m) = 12/7
(3,7)...x = 3 and y = 7
now we sub, we r looking for b, the y int
7 = 12/7(3) + b
7 = 36/7 + b
7- 36/7 = b
49/7 - 36/7 = b
13/7 = b
so ur equation is : y = 12/7 + 13/7.....slope = 12/7, y int = 13/7

HI : (-1,0)(4,6)
slope = (6 - 0) / (4 - (-1) = 6/5

no need to go any farther.....these lines have different slopes...and their not negative reciprocals....so there will be one solution. Answer is : neither.
