which of the following equations does the graph show below pls help l give u the branliest answer or wtvr

Answers

Answer:

x - 5y = 5

Step-by-step explanation:

Let's represent the equation of the graph in slope-intercept form, y = mx + b.

We'd need to find slope (m) and y-intercept (b) of the graph.

Slope (m) = ∆y/∆x

Using two points on the line, (0, -1) and (5, 0),

Slope (m) = (0 - (-1)) / (5 - 0) = 1/5

m = ⅕

y-intercept (b) is the point on the y-axis where the line intercepts the y-axis = -1

Therefore, b = -1

To write the equation, substitute m = ⅕ and b = -1 into y = mx + b

Thus:

y = ⅕(x) + (-1)

y = ⅕(x) - 1

Rewrite in standard form:

-⅕x + y = -1

Multiply both sides by -5

-⅕x*-5 + y*-5 = -1*-5

x - 5y = 5

Think about how you can use the diagram to figure out the statement of the Pythagorean Theorem

Answers

Answer:

Step-by-step explanation:

Remark

There are many ways you can do this. You could, for example, prove this by using just one diagram and do the algebra for that one diagram. Or you could use both diagrams and equate them. I'll do the latter.

Left Diagram

c^2 + the 4 small triangles surrounding c^2 gives

c^2 + 4 * (1/2 * a * b)

Right Diagram

2 * a * b + a^2 + b^2

By the symmetry of the situation, you can find the area of the figures in each diagram. Since a in the left is equal to a on the right, and since b on the left = b on the right, the areas are equal.

Solution

c^2 + 4(1/2 a*b)  = 2 * a * b + a^2 + b^2

c^2 + 2*a*b = 2* a * b + a^2 + b^2

c^2 = a^2 + b^2  

Notice that the 2ab on the left cancels out with the 2ab on the right.

write the expression as a square of a binomial: 9/25a^6b^2-a^4b^4+25/36a^2b^6

The weight of the load varies
directly with the number of boxes
in the load. A load of 18 boxes
weighs 600 lbs. What does a load
of 12 boxes weigh?

Answers

The weight varies directly with the number of boxes, so this means every box weighs the same amount.

Find the weight of a box by dividing the known weight by the number of boxes:

600 pounds / 16 boxes = 37.5 pounds per box.

Now multiply the weight per box by the number of boxes:

37.5 pounds x 12 boxes = 450 pounds

12 boxes weigh 450 pounds
