Answer:
The equation of the line in the slope-intercept form will be:
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
From the attached graph, taking two points
Finding the slope between (0, 0) and (-10, 70)
Determining the y-intercept:
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = -7 and b = 0 in the slope-intercept form
y = mx+b
y = -7x + 0
y = -7x
Therefore, the the equation of the line in slope-intercept form will be:
First you have to find out how old ben is
then times it by 3
Use algebra to figure out the answer
i am telling you this because i don't know the answer
Hello! So Brian is 6 feet tall and casts a 4 foot shadow and the tree’s shadow is 20 feet. To find the height of the tree, we can write and solve a proportion. Set it up like this:
6/4 = x/20
This is because we are looking for the height of the tree, and having it set up like this will help us get to the right answer. Let’s cross multiply. 6 * 20 is 120. 4 * x is 4x. That simplified to 120 = 4x. Now, divide each side by 4 to isolate the x. 4x/4 cancels our. 120/4 is 30. Let’s cross multiply to check out answers. 6 * 20 is 120. 30 * 4 is 120. 120 = 120. There. x = 30. The tree is 30 feet tall.
