4(5) + 5(6) - (-4/-2)
.
just to help keep the signs straight, but there is nothing wrong with the way you did it.
.
Now you can just start simplifying ... term by term. Multiply the 4 times the 5 and you get:
.
20 + 5(6) - (-4/-2)
.
Then multiply the 5 times the 6:
.
20 + 30 - (-4/-2)
.
Next divide the terms in the parentheses. -4 divided by -2 is +2 and you have:
.
20 + 30 - (+2)
.
When you remove parentheses preceded by a minus sign, you change the signs of the terms
inside the parentheses. So - (+2) becomes -2 when the parentheses are taken out and the
expression becomes:
.
20 + 30 - 2
.
Now add the three terms and the result is +48
.
Hope this clarifies the problem for you. Good job ...

Graph the step function on paper and you will see that the maximum y-value is 5. Thus the only possible answer is B.
f(x) ≤ 5
12.5
1 decimetre is equal to 0.1 meter
Times that by 125 to get 12.5
We conclude that the distance between points C and D is 5 units.

How to find the distance between the two points?</h3>
Remember that if we have two points (x₁, y₁) and (x₂, y₂), the distance between these points is:
d = √( (x₂ - x₁)^2 + (y₂ - y₁)^2)
In this case, we know that:
Point C has the coordinates (-1, 4)
Point D has the coordinates (2, 0)
Then the distance between these two points is:
d = √( (-1 - 2)^2 + (0 - 4)^2) = √25 = 5
We conclude that the distance between points C and D is 5 units.

Answer:
m = 1/3, b = 2
Step-by-step explanation:
The equation is already written is slope-intercept form, y = m x + b.
