Determine the percentage of the shaded cubes
First, we calculate the number of boxes:

Express as multiplication


This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:





<em>30% were shaded</em>
Step-by-step explanation:
To solve this, you either need x or y. So x or y can be the missing values. The most you can do is simply move one of the terms to the other side.
Answer:
C. 
Step-by-step explanation:
First, find the slope, m, of the line that passes through the two given points.
Slope = 
Next, determine the y-intercept, b.
The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.
Now, to get an equation of the line, substitute m = -1, and b = 2 in
.
✅The equation would be:


64000 x 0.12 = 7680

Answer:
23
Step-by-step explanation:
You can simply substitute -2 into the x of the equation.
f(-2) = (-2)^4 + 2(-2)^2 -1
= 23
