Answer:
Kaylaa do you use desmos graphing calculator? it's an online graphsing tool and would make this very easy for you. Maybe you are not allowed to use a calculator?
Step-by-step explanation:
with out a calculator it's a long math process, 1st because each of the equations are equal to Y, we can set each of them equal to each other. like this
+ 3 = - + 18
= - +18 -3
= - + 15
= -[ (x-5)*(x-5) ] + 15
= -[ - 10x + 25] +15
= - + 10x -25 +15
= - + 10x -10
- = - 10x +10
(- )^2 = ( - 10x +10)^2
this turns into a 4 order polynomial. I used a solver to find x
x = 8.75884.... approx
so the question asks what is the point at the nearest 1000th, which is 8.759
then they ask what is the point at the nearest 100th, which is
8.76
I'm attaching the graph, if it helps :P
Y=4x²-7x+13
y-13=4(x²-(7/4)x)
y-13+4*(7/8)²=4(x²-2*(7/8)x+(7/8)²)
y-13+4*(7/8)²=4(x-(7/8))²
y-13+ 3.0625=4(x-0.875)²
y-9.9375=4(x-0.875)²
y=4(x-0.875)² +9.9375
Answer:
Step-by-step explanation:
the graphs of the equation x=3 and y=3 intersect each other at point (3 , 3)
x = 3 is parallel to x-axis and y = 3 is parallel to y- axis

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
