Answer:
Step-by-step explanation:
you multiply across, so you do 2*2 for the numerator, then 3*3 for the denominator. This would equal 4 as the numerator, 9 as the denominator, which is
Y=40x+25 y is the total he has, 40x is he makes 40 per week, and 25 he already has
Answer:
A,C,D
Step-by-step explanation:
well, you can figure it out by substituting the x and y values into the equation and then solving
4=2(4)-4
4=8-4
4=4 so yes the point (4,4) does lie on the line y=2x-4
We know that x > 2 ( or : x ≠ +/- 2 )
We have to factorize the numerator and the denominator:
x² - x - 6 = x² - 3 x + 2 x - 6 = x ( x - 3 ) + 2 ( x - 3 ) = ( x - 3 ) ( x + 2 )
x ² - 4 = ( x - 2 ) ( x + 2 )
