Answer: x equals to 2 and -5
Step-by-step explanation:
» Factorise the equation quadratically:
Answer:
Convert to a decimal by dividing the numerator by the denominator.
1
distinct
Step-by-step explanation:
The image of x is the point (7,5).
Draw the line x= 3 and treat it like a mirror.
When you reflect the points of the triangle just count how many units each point is from the mirror (x=3)
Count the same number of points in the opposite direction (away from the mirror) and you will arrive at the coordinates for the points
The ordered pair (- 3, 1 ) is a solution to the second equation because it makes the second equation true
To test , substitute the coordinates of (- 3, 1) into the equations and if both sides are true then it is a solution to the equation.
x - 4y = - 3 - 4 = - 7 ≠ 6 ← not true
(3 × - 3) + 1 = - 9 + 1 = - 8 ← true
Thus (- 3, 1 ) is a solution to the second equation
