the equation of the line is y = 3/5x + 3
What is x?
It is the number of years since purchase. Can this be negative?
NO! Years cannot be negative. So we disregard negative x-axis.
What is y?
It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?
NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.
The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).
ANSWER: Quadrant I only
Answer:
True
Step-by-step explanation:
You're claiming that every set is a subset of itself.
That's trivially true, because
requires that every element of A is also an element of A, which is tautologically true.
Answer:
F. 45/4
Step-by-step explanation:
hypotenuse/long leg of both triangles:
- 15/20=x/15
- x=15*15/20
- x=45/4
Answer:
The equation can be expressed as;
x+y=71 where,
Lengths of two equal sides=x=22 m
Lengths of longer side=y=27 m
Step-by-step explanation:
The total perimeter can be expressed as;
Total perimeter=Total length of the equal sides+total length of the longer side
where;
Total perimeter=71 m
Total length of each of the equal sides=x m
Total length of longer side=y=(x+5) m
replacing;
x+y=71...equation 1
71=(2×x)+(x+5)
2 x+x=71-5
3 x=66
x=66/3
x=22 m
y=x+5=22+5=27 m
Lengths of two equal sides=22 m
Lengths of longer side=27 m
Equation;
x+y=71
