Answer:
Option 3
y + 16 = 8(x + 2)
Step-by-step explanation:
<h3>
<u>Given</u>;</h3>
- x = 2, 4, 6, 8
- y = 16, 32, 48, 64
Now, Put the values in equation 1
y – 16 = 8(x – 2)
y – 16 = 8(x – 2)
16 – 16 = 8(2 – 2)
0 = 8
Here, L.H.S ≠ R.H.S
So, Option 1 is incorrect
Now, Put the values in equation 2
y – 16 = 8x – 2
y – 16 = 8x – 2
16 – 16 = 8(2) – 2
0 = 14
Here, L.H.S ≠ R.H.S
So, Option 1 is incorrect
Now, Put the values in equation 3
y + 16 = 8(x + 2)
y + 16 = 8(x + 2)
16 + 16 = 8(2 + 2)
32 = 8(4)
32 = 32
Here, L.H.S = R.H.S
Check other values of x and y
y + 16 = 8(x + 2)
32 + 16 = 8(4 + 2)
48 = 8(6)
48 = 48
Here, L.H.S = R.H.S
y + 16 = 8(x + 2)
48 + 16 = 8(6 + 2)
64 = 8(8)
64 = 64
Here, L.H.S = R.H.S
y + 16 = 8(x + 2)
64 + 16 = 8(8 + 2)
80 = 8(10)
80 = 80
Here, L.H.S = R.H.S
Thus, The equation 3 in point-slope from gives the plant's height at any time.
<u>-TheUnknownScientist 72</u>
Answer:
Step-by-step explanation:
7. Let the price of book be x
:- 8x + 17 = 129
8x = 129 - 17
8x = 112
x = 112/8
x = $14
Each book cost $14
8. Let the number of hours be x
9x + 15 = 87
9x = 87 - 15
9x = 72
x = 72/9
x = 8hrs
He paid for 8hours
9. Let the numbers be x, x +2, x +4,
So. x + x + 2 + x + 4 = 168
3x + 6 = 168
3x = 168 - 6
3x = 162
x = 162/3
x = 54
The smallest number is 54
10. Let the number of books be x
So, x/2 + 6 = 18
x/2 = 18 - 6
x/2 = 12
x = 12 ×2
x = 24
So she has 24 book's before
Answer: 60/2
Step-by-step explanation:
When you multiply 60 and 1/2 you get 30 which is the same as 60/2
-2(1+5a)=-6(a+3)
Expand the brackets:
-2-10a=-6a-18
Add 10a to each side:
-2=4a-18
Add 18 to each side:
16=4a
Divide each side by 4:
4=a
Hope this helps :)
