Answer:

The easiest way to find the equation of a parabola is by using your knowledge of a special point, called the vertex, which is located on the parabola itself.

Step-by-step explanation:

If you see a quadratic equation in two variables, of the form y = ax2 + bx + c, where a ≠ 0, then congratulations! You've found a parabola. The quadratic equation is sometimes also known as the "standard form" formula of a parabola.

Sara is 6 feet 3 3/4in tall and Sam is 5 feet 6in. How much taller is Sara then Sam?

denpristay [2]

Answer:

9 3/4 inches

Step-by-step explanation:

If we are finding how much taller Sara is, we need to subtract

6 ft 3 3/4 - 5 ft 6in

I like to line up vertically

6 ft 3 3/4

- 5 ft 6in

----------------

We need to borrow 1 ft and make it 12 inches

5 ft 3+12 3/4

- 5 ft 6in

----------------

5 ft 15 3/4

- 5 ft 6in

----------------

What is the equation of a line in point-slope form that passes throught -8, 1 and has a slope of 5/6

Flauer [41]

Answer:

5x - 6y +36 =0 is the required equation.

Step-by-step explanation:

(x1, y1) =(-8, - 1)

Slope (m) =5/6

The equation is:

(y - y1) =m(x-x1)

y +1=5/6(x +8)

6y +6 =5x +40

5x - 6y +36 =0 is the required equation.

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5

Phoenix [80]

Answer:

3

Step-by-step explanation:

So we have the function:

$f(x)=3x^2+2x-5$

To evaluate the value of f(-2), substitute -2 for x. Thus:

$f(-2)=3(-2)^2+2(-2)-5$

Square first:

$f(-2)=3(4)+2(-2)-5$

Multiply:

$f(-2)=12-4-5$

Now, subtract:

$f(-2)=8-5=3$

So:

$f(-2)=3$

And we're done!

Solve with explanation -4x+5> - 5

Bezzdna [24]

Answer:

$x < 2.5$

Step-by-step explanation:

$- 4x + 5 > - 5 \\ - 4x > - 5 - 5 \\ - 4x > - 10 \\ \frac{ - 4x}{ - 4} > \frac{ - 10}{ - 4} \\ x < \frac{5}{2} \\ x < 2.5$

hope this helps
