Answer:

The center is (1,4)

Step-by-step explanation:

The coordinates of the center of an ellipse are the coordinates that are in the middle of the two focus.

Then if we have a focus on (x_1,y_1) and (x_2,y_2), we can say that the coordinates for x and y can be calculated as:

x=\frac{x_1+x_2}{2}\\ y=\frac{y_1+y_2}{2}

So, replacing (x_1,y_1) by (-4,4) and (x_2,y_2) by (6,4), we get that the center is:

x=\frac{-4+6}{2}=1\\ y=\frac{4+4}{2}=4

The answer is 43. What I did was I added all the numbers together, and since they wanted the area, and to find the area you multiply TWO numbers together, I multiplied the sum by 2 and I got 43. Hope this helps!

Write an equation in slope intercept form for the line that passes through (2,-2) and is parallel to y=-5/2x+5
DENIUS [597]

y=mx+b\\y=x-2

<em>Only y= x - 2 intercepts x-axis at 2 and y-axis at -2. Thus meaning that they intercept oppositely.</em>

<em>Find if both graphs are parallel, that means the equation must be false.</em>

<em />x-2=-\frac{5}{2}x+5<em />

<em>Multiply whole equation by 2 to get rid of the fractional 2.</em>

<em />2x-(2)(2)=-\frac{5}{2}(2)(x)+5(2)\\ 2x-4=-5x+10\\2x-4+5x-10=0\\7x-14=0\\7x=14\\x=2<em />

<em>Well, that doesn't seem to be parallel. This is called one solution answer. Both graphs intercept at (2,0). There are no linear graphs that intercept at (2,-2) except for y = x-2 so there are no graphs with (2,-2) that are parallel to the equation y = -5x/2+5 </em>

kenny has 9 more comic books than bobbie. together they have 95 comic books. define a variable. then write an equation that coul
Hoochie [10]
Number of comic books Bobbie has - b

95 = (9 + b) + b

Since 95 is the total number of comic books both boys have, it is equal to both boys' books added together. However, since we don't know how many books Kenny has, and only that he has 9 more than Bobbie, we can define that as (9 + b), or nine more than b. Then, we add b again, because (9 + b) is the number of books Kenny has, and if we add that to the number of books Bobbie has, it will equal the total of 95 comic books.
