If a line is parallel to another, the slopes of both lines are the same. So for this problem, you can infer that the slope of the line you're trying to find is 3.
To find the actual equation of the line, you can use the given coordinates and plug them into the point slope form:
y - y1 = m(x - x1)
plug the given y coordinate into y1 and the given x coordinate into x1. m is the slope, so plug in 3 for m.
y - 1 = 3(x +2) Use distributive property for right side of equation
y - 1 = 3x + 6 add 1 to both sides to cancel -1 on left side of equation and isolate y
Equation of line: y = 3x + 7
Answer: x = 4,11
Step-by-step explanation:
x^2 - 7x - 34 - 10 = 0
x^2 - 7x - 44 = 0
Factorise it
x^2 - 11x - 4x - 44 = 0
x ( x - 11 ) - 4 ( x - 11 ) = 0
(x-4)(x-11) = 0
x = 4,11
Answer:
251
Step-by-step explanation:
Tn=5n+1
e.g.T1=5(1)+1
=6
e.g.T2=5(2)+1
=11
e.g.T3=5(3)+1
=16
e.g.T4=5(4)+1
=21
Answer:T50=5(50)+1
=251
It is T because the sign in front of 50 means to square the number after it. So 50/2=25.
Answer:
x >= 0 & y<0
x >= 0 means that x is non-negative
y<0 means that y is negative
