Answer:
11, 12, and 13
Step-by-step explanation:
15x + 28y = 116
x + y = 6
that would be ur system of equations
Yes your right it equals 300 thousandths
Answer:3x^2 each coefficient is divisible by 3 and and you can take x^2 from both of them
Hello,
Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2
Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4
One other way:
y=9-1/2 x²
y'=-x
gradient 1=-(-2)=2 for point (-2,7)
gradient 2=-(4)=-4 for point(4,1)
