Answer:

Step-by-step explanation:

The acronym PEMDAS is helpful when learning order of operations. It stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction which is the order in which you solve an equation. For this set of numbers there are no parenthesis or exponents so you would start by multiplying 3*2=6 Then add the 8 to the 6 and you get 14 Subtract the 4 and the answer is 10

Step-by-step explanation:

Use the equation rise over run, which is also y2-y1 over x2-x1

in basically every type of thing, x always comes first then y

y2=1 y1=6 x2=-2 x1=-4

1-6/-2-(-4)=-5/-6, because it was changed to, -5/-2+4

Write the equation of the hyperbola with foci at (1, 5) and (7, 5) and with vertices at (2, 5) and (6, 5).

mash [69]

If you plot the points given on a coordinate plane you see that this is a hyperbola that is is horizontal in nature, meaning it opens side to side, not up and down. We can determine the center of it by taking the point equidistant from the vertices, which is (4, 5), the h and k of our center, respectively. Also, the equation looks like this when it is horizontal: $\frac{(x-h) ^{2} }{ a^{2} } - \frac{(y-k) ^{2} }{ b^{2} } =1$ . a is the distance between the center and the vertices, so our a = 2, and c is the distance between the center and the foci, so our c = 3. We need to find b now, using Pythagorean's theorem. $( 2)^{2} + b^{2} =( 3)^{2}$ and $b= \sqrt{5}$ . Now we have everything we need to rewrite the equation: $\frac{(x-4) ^{2} }{4} - \frac{(y-5) ^{2} }{5} =1$
