Answer:
1/2
Step-by-step explanation:
divide the numerator & denominator by 4
Step-by-step explanation:
to work out gradient
change in y ÷ change in x
first lines gradient
(7 - - 8) ÷ (7 - 7) = 0
second lines gradient
(7 - 7) ÷ (9 - - 6) = 0
The answer to this problem is -4y+9x
Answer:
4 because 5 times 4 is 20 and 3 times 4 is 12
Answer:
x=7 x=-1
Step-by-step explanation:
x^2 - 6x - 7 = 0
Factor
What two numbers multiply to -7 and add to -6
-7*1 =-7
-7+1 = -6
(x-7) (x+1) = 0
Using the zero product property
x-7 =0 x+1 =0
x=7 x=-1
