Answer:
Step-by-step explanation:
If by opposite you mean...
1 opposite is -1
If so then its 0 because any rational number and its reciprocal is always 0 its math crazy stuff
Answer:
y=x is the correct answer
Explanation:
A linear equation is an equation between two variables that gives a straight line when plotted on a graph.
Why the other ones are incorrect:
y=√x gives a radical function graph
y=x^3 gives a cubic graph
y=x^2 gives a parabola
Answer:
the answer would be 16
Step-by-step explanation:
12 1/2 - -4 1/2=??? 1/2 - 1/2= 0 so 12 - -4=16
hope this helps
Answer:
= 8sqrt2
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
;
Where a and b are the parallel sides and h is the perpendicular height.
a = 3 cm, b= 5 cm
To get; h, we use the Pythagoras theorem;
h² = 3² - 1²
h² = 8
h = √8
= √4√2
= 2√2
Thus;
Area = 1/2(3 +5) 2√2
= 1/2 ×8 × 2√2
<u> = 8√2 cm² or 8sqrt2 cm²</u>
If f(x) = 6x , then f(2) = 6(2) or f(2) = 12... simply substitute the argument in for the variable in your expression on the right.
