Answer:
y = 9 - 5x
[x = -1] 14
[x = 0] 4
[x = 4] -11
Step-by-step explanation:
Step 1: Define
y + 5x = 9
x = -1, 0, 4
Step 2: Solve for <em>y</em>
y = 9 - 5x
Step 3: Plug in values of <em>x</em>
y = 9 - 5(-1) = 14
y = 9 - 5(0) = 4
y = 9 - 5(4) = -11
If x = -6
we can subtitution x to every inequality, so :
-5 - 3x > 10
-5 - 3(-6) > 10
-5 - (-18) > 10
-5 + 18 > 10
13 > 10 [true]
-3 - 5x < -14
-3 - 5(-6) < -14
-3 - (-30) < -14
-3 + 30 < -14
27 < -14 [false]
2 - x < -3
2 - (-6) < -3
2 + 6 < -3
8 < -3 [false]
So if x=-6, inequality true is -5 - 3x > 10.
Answer:
x = 7
Step-by-step explanation:
3x - 7 = 2x
- 7 = -1x
x = -7/-1
x = 7
Answer:
A
Step-by-step explanation:
Given
3
When the culture was created t = 0, thus
3 = 3 × 1 = 3
That is there were initially 3 bacteria in the culture → A
