Hello,
The equation of the parabola is
y=k(x-1)²-9
and -6=k(0-1)²-9==>k=3
x-intercepts is:
y=0==> 3(x-1)²-9=0==>(x-1)²=3
==> x=1+√3 or x=1-√3
Answer:
13
Step-by-step explanation:
x^2=5^2+12^2
x^2=25+144
x^2=169
x=13
21/4 ÷ 14/9
21/4 × 9/14
189/56
3/3/8
Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.
I drew this by hand. sorry I it does not help.
