Answer:
(-3,2) is the solution to the system of equation
Step-by-step explanation:
Here, we want to know the point that serves as a solution to the system of equation
We equate the y
-2x + 4 = -1/3x-1
Multiply through by 3
-6x + 12 = -x-3
-6x + x = -3-12
5x = 15
x = 15/5
x = 3
Substitute x into one of the y
y = -2(3) + 4
y = -6 + 4 = -2
So the solution is;
(3,-2)
Y=ax² + bx + c and A(-2,18), B(0.4), C(4,24) given
1)Let's determine 1st the value of c in using the pair of B
4= a(0)² + b(0) + c , c=4 and y=ax²+bx+4
2) Use the pair of A: 18 = 4a -2b + 4===> 4a-2b=14
3) Use C pair: 24 = 16a+4b+4 ==> 16a+4b=20
4) solve the system equation in 2) and 3) and you'll find a=2 and b=-3
Hence the equation is y =2x²-3x+4
Answer:
no
Step-by-step explanation:
Using substitution, subs in the points given
(15) = 5(4) - 2
15 = 20 - 2
Because the 2 sides are NOT equal the line would not pass through the point
