The curve described described here is an ellipse with eccentricity e=\dfrac45, the ratio between the distance from the given focus F(4, 0) to any point Q along the directrix x=\dfrac{25}4. Use this info to find the lengths of the semimajor and -minor axes, a and b. Then the area of the ellipse is \pi ab.

The triangles are similar by the AA Similarity Postulate. Find the value of x
alexandr1967 [171]
4.5/3= 1.5

It is 1.5 times bigger than the smaller triangle.

So,

5*1.5= 7.5

x= 7.5

I hope this helps!

A line passes through the point (-3, -3) and has a slope of 1/2. What is the equation of the line?
harina [27]
To solve this, we need to understand Slope Intercept Form (SIF), as well as how to graph a line.

SIF is the standard equation of lines on graphs. It is "y=mx+b" where m is the slope and b is the y-intercept. The y-intercept is the value of y when x is 0.

To find the y-intercept (which we will need to form the equation), we should simply graph the line. This will let us visualize the y-intercept, and overall make it easier to understand.

To graph a line, we should start with the point we have (that being (3, 3)) and follow the slope with rise/run. This means in this case, we will go right 2 for every 1 up, or 2 left for every 1 down.

Below I have attached a graph to help you see how to graph this, which we will get our equation from. The highlighted area is our y-intercept. The red circle shows our original point (3,3), and the blue dots show our slope.

Using the graph, we can see the equation for this line is y=1/2x+1.5.

How do you solve this?
NNADVOKAT [17]

Answer:

C.)

Step-by-step explanation:

The graph is positive this time, so right away you can eliminate A and B.

If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.
