Answer:
Asking who is the best singer at a Taylor Swift concert.
another example
Asking what's a better icecream strawberry or chocolate in a 6th grader lunch period only.
First, let's put that line in standard form
y - 3 = 3(x + 1)
y - 3 = 3x + 3
y = 3x + 6
(Standard form is y = mx+b, where m is slope and b is y-intercept.)
Now, a line parallel to that line would have the same slope of 3. So now we have m = 3. Plug that in for m and now we have
y = 3x + b
But we still need the b value. We can get that by plugging in the point (0, -3)
(-3) = 3(0) + b
-3 = 0 + b
b = -3
Now put b back into the equation and your final equation is
y = 3x - 3
Answer: About 9.2
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem. We are solving for the hypotenuse which is the "c" variable in the formula.
a² + b² = c²
7² + 6² = c²
7² + 6² = c²
49 + 36 = c²
85 = c²
= c
9.2 ≈ c
There are 2 real solutions to the equation. Evaluate the discriminant = 8. Using the quadratic formula = What is on the picture.
