Draw the given answers to determine the correct solution.

ΔABE is correct because it is a right triangle through a diagonal
ΔABD is incorrect because it does not go through diagonals.
ΔADH is incorrect because it does not go through diagonals.
ΔACE is incorrect because it does not go through the interior of the cube.

Answer: ΔABE

What is an equation of the line that passes through the point (-5,-3)(−5,−3) and is parallel to the line 3x+5y=15

Sunny_sXe [5.5K]

Answer:

y = -3/5x - 6 or 3x + 5y = -30

Step-by-step explanation:

Given line:

3x + 5y = 15

Converting into slope-intercept form:

3x + 5y = 15
5y = - 3x + 15
y = -3/5x + 3

Parallel lines have the same slope, so the parallel line will be:

y = -3/5x + b

Using given point (-5, -3) finding the y-intercept:

-3 = -3/5(-5) + b
-3 = 3 + b
b = -3 - 3
b = -6

So the line is:

y = -3/5x - 6

Or converted into standard form:

y = - 3/5x - 6
3/5x + y = -6
3x + 5y = -30

I NEED HELP LIKE NOW PLS! I'll give you brainliest answer if you can help me ((:

The first word of the question is cut out of the picture, so we don't exactly know what the assignment is. But we can see that the graph of f(x) will do something weird when x=-3, because the denominator will be zero, and division by zero doesn't even have a definition or meaning. Just for fun, you should go ahead and calculate the numerator when x=-3, and that totally blows your mind, because the numerator is zero too. So you've got. f(-3)= 0/0 , and I can pretty much guarantee that you won't be able to plot that point anywhere on the graph. (I'm pretty sure that f(-3) is actually going to turn out to be -13, but even if I'm correct, you probably haven't learned that little calculus trick yet, so don't worry about it. As far as you're concerned, f(-3) is 0/0, and can't be plotted.)
