Answer: Upper left corner
Explanation:
The error happens in step 2. Notice that x is <u>not</u> part of the second term 16, so there's no way to factor x from it unless you want a fraction to result.
The second step should be 8(4x-2)
Another way to factor is to say 16(2x-1)
Answer:

The beginning balance of Sophie's account is 75
Step-by-step explanation:
Using the slope intercept form aka 
The slope of a line describes how steep a line is.
- We can see that the y-axis goes up by 25.
- 25, 50, 75, 100, 125, 150 etc
<u>$ is how much you have in your bank account.</u>
<em>We can see that Sophie starts off with 75 dollars.</em>
In the first week, we see that Sophie has 100 dollars. In the second week, we see that Sophie has 125.
<h3>how to find the slope</h3>

The first week (1, 100)
The second week (2,125)

Dy/dx = dy/dt * dt/dx
xy = 4
y + x(dy/dx) = 0 by implicit differentiation.
x(dy/dx) = -y
dy/dx = -y/x
<span>dy/dx = dy/dt * dt/dx dy/dt = -2
</span>
<span>-y/x = -2 * dt/dx
</span>
y/(2x) = dt/dx
dt/dx = y/(2x)
dx/dt = 2x/y
When x = -3, xy = 4, y = 4/x = 4/-3 = -4/3
dx/dt = 2*-3/(-4/3) = -6 *-3/4 = 18/4 = 9/2 = 4.5
dx/dt = 4.5
Answer:
0.89736
Step-by-step explanation:
We solve this question using z score formula
Z score = x - μ/σ
x = raw score
μ = population mean
σ = population standard deviation
Hence,
x = 258, μ = 220, σ = 30
Z = 258 - 220/30
=1.26667
Probability value from Z-Table:
P(x<258) = 0.89736
Therefore, the probability that his weights is less than 258 kg is 0.89736
