Answer:
C and E are not on the line.
Step-by-step explanation:
Just substitute for the x and the y and see which ordered pair fits and which does not:
If Left side of the equation = right side then the point fits.
A. y = -3
-2x+5 = -2(4) + 5 = -3 So A is on the line
B. y = 9
-2(-2) + 5 = 9 So this point does lie on the line.
C. y = 1
-2(3) + 5 = -1 No.
D. y = 7
-1(-1) + 5 = 7 YES.
E. y = 1
-2(1) + 5 = 3 NO.
Answer:
Step-by-step explanation:
Slope of the line through (0,3) and (2,5) = (5-3)/(2-0) = 1.
Equation of line: y = x+3
When x=3, y=6
(3,n) = (3,6)
9 because 9x3=27 or 27/3=9
Answer:110
Step-by-step explanation:x^2+17x=15x+35
x^2+17x-15x-35=0
x^2+2x-35=0
delta=2^2-4*1*(-35)=4+140=144
x1=(-2+V144)/2=(-2+12)/2=10/2
x=5
so 15*5+35=75+35=110
Answer:
answer is 1/4
Step-by-step explanation:
proof is (x-1/2)²= x²-2*1/2*x+1/4= x²-x+1/4
