Hello there!
-6x + 5 - 4(x - 1) = -4x - (5x - 3) + 4
We need to use the distributive form
-6x + 5 + (-4)(x) + (-4)(-1) = -4x - 5x + 3 + 4
-6x + 5 - 4x + 4 = -4x - 5x + 3 + 4
-10x + 9 = -9x + 7
Now we can subtract 9 from both sides
-10x + 9 - 9 = -9x + 7 - 9
-10x = -9x - 2
Add 9x to both sides
-10x + 9x = -9x + 9x - 2
-x = -2
We cannot leave it with a negative sign, divide both sides by -1
-x/-1 = -2/-1
x = 2
I hope the steps are clear to understand. If you have any misunderstanding feel free to let me know.

so, notice, the slope of that equation is just -4/5, and any parallel line to it will have the same exact slope.
so we're really looking for the equation of a line whose slope is -4/5 and runs through x-intercept of 3, namely (3,0).
The pot = 1/2
The cat = 1/4
The pumpkin = 1
The zombie hand = 1/3

Answer:
Mean = 17.1
SD = 3.72
Step-by-step explanation:
FROM the question;
n = 0.19 and the probability of success is 0.19
Mean = np = 0.19 * 90 = 17.1
The standard deviation is as follows;
√np(1-p)
SD = √(17.1)(0.81)
SD = √13.851
SD = 3.72
