Answer:
Hi!
The name of the equation is the Pythagorean Theorem.
A and B both are the lengths of the legs of a right triangle, while C is the length of the hypotenuse.
Hope I helped! Have a good day :)
Answer:
4(6/8) - 1(1/8) = 29/8 Greater than 1
1/9+1/4 = 13/36 = Less than 1/2
1(1/3) - 7/8 = 11/24 = Less than 1/2
5/6 + 4/5 = 49/30 = Greater than 1
2(3/4) - 1(2/3) = 13/12 = Greater than 1
1/3 + 3/5 = 14/15 = Between 1/2 and 1
Ok use the equation for slope which is rise over run and then plug into the equation y= mx+b and solve for b and then use in the equation
The perimeter is 166.9 ft.
Convert feet to inches to make it easier to calculate. The formula to find the perimeter is... 2(w+h)
once you get your answer, convert inches back to feet.
VERTEXTo determine the vertex (coordinate x) of parabola y = ax² + bx + c, use this following formula
x vertex =

y = x² - 2x - 48
a = 1, b = -2, c = -48
plug in the numbers
x vertex =

x vertex =

x vertex =

x vertex = 1
To find y vertex, substitute the value of x vertex to the parabola equation
y = x² - 2x - 48
y = 1² - 2(1) - 48
y = 1 - 2 - 48
y = -49
The vertex is (1, -49)X-INTERCEPTx-intercept located in x axis, that means y = 0. Substitute y = 0 to the parabola equation
x² - 2x - 48 = y
x² - 2x - 48 = 0
(x - 8)(x + 6) = 0
x = 8 or x = -6
The x-intercepts are (8,0) and (-6,0)The answer is first option
