Answer:
y=-x+8
Step-by-step explanation:
y = mx + b is the basic formula
use the formula y2-y1/x2-x1 to get the slope to get m
-2-5/4-(-3)
-7/7
-1
then use the point slope formula y-y₁=m(x-x₁)
y-5=-1(x-(-3)
y-5=-1x+3
y=-x+8
Answer: (x^2)/16 + (y^2)/25 = 1
Step-by-step explanation:
According to the problem we can figure out that the center of the ellipse is (0,0).
Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.
If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2
We get b^2 is 16
Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.
Answer:
$31.5
Step-by-step explanation:
-$45
-30 percent off of $45
30 times 45 divided by 100
1350/100
13.5
45-13.5
$31.5
