Once you have found the value of one of the variables(let's say x), you can substitute the value of the variable(x) into the variable(x) of one of the original equations to find the second variable.
Answer:
Explained in detail below
Step-by-step explanation:
4/28 = 1/7 = 1:7
Answer:
The fourth answer choice is the correct one: 2(x - 3)
Step-by-step explanation:
2x²-18x+36/x-6 should be factored, as follows:
2(x²-9x+18) / (x-6) = 2(x - 3) (x - 6) / (x - 6)
Substituting x = 6 would result in division by zero and is thus not allowed.
Remembering this, we can reduce 2(x - 3) (x - 6) / (x - 6) to 2(x - 3) for x≠6.
Answer:
perpendicular
Step-by-step explanation:
x = 4 is a vertical line.
y = -2 is a horizontal line.
The lines are perpendicular.
To divide fractions:
Flip the second fraction
Multiply the numerators
Multiply the denominators
Simplify
2/9*10/9
2*10=20
9*9=81
20/81
