Answer:

A = 387

Step-by-step explanation:

An easy way to do this would be to divide them into 3 rectangles, like in the pic I have attached.

Then, solve the area of each rectangle, and add them.

The formula for area for a rectangle is length times width.

The equation for the big rectangle is 10 times 24 = 240

The equation for the middle rectangle is 6 times 19 = 114

The equation for the small rectangle is 3 times 11 = 33

Now, to find the area of the whole shape, we have to add the areas of the 3 rectangles:

240 + 114 + 33 = 387

Answer:

y= $-\frac{4}{3}$ x+2

Step-by-step explanation:

To write the equation for this line, we are going to use slope-intercept form, which is written as

y=mx+b.

Here are the meanings of each variable:

y= basically the "name" of the function and it always stays as y.

m= slope, which is rise over run.

x= variable that is always on the right of the slope and it always stays as x.

b= y-intercept, or the value that crosses the y-axis.

We will substitute numbers into the equation along the way. The first thing we will want to do is find b, which is the easiest.

The line crosses the y-axis at 2, so that is our value of b.

Our new equation is

y=mx+2.

Next, we will find the slope. The most efficient way of doing this is looking at the lowest point that is already provided, (3, -2), and finding a way to rise and run to the highest point, (0, 2).

If you look closely at the graph, we need to rise up 4 and run over -3 to get to the other point. Therefore, the slope is $-\frac{4}{3}$ , and we can substitute it into our equation, which is completed and is now

y= $-\frac{4}{3}$ x+2

I hope this helps you out!! Have an awesome day ^^

A point M on a segment with endpoints X(1, −2) and Y(10, 3) partitions the segment in a 4:1 ratio. Find M. You must show all wor

Answer:

$\displaystyle \: M = \left( 8\frac{1}{5},2\right)$

Step-by-step explanation:

we want to figure out the point "M" which is on a segment with endpoints X(1,-2) and Y(10,3) partitions the segment in a 4:1 ratio.

to find so, we can consider section formula . we know that Section formula is used to find the ratio in which a line segment is divided by a point internally or externally the ratio is written as m:n

however in this case the following formula can be used used:

$\displaystyle \left( \frac{m x_{2} +n x_{1}}{m + n} , \frac{m y_{2} + n y_{1}}{m +n}\right)$
