Answer:
y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.
Step-by-step explanation:
The answer is D.
First solve for y.
You end up with:
y=-1/2x+3/2
Because they want a parallel line, the slope stays the same.
Our equation will look like
y=-1/2x+b
Now plug in the given coordinates
4=-1/2(6) + b
4=-3+b
b=7
Therefore, the equation of the line is
y = -1/2x + 7
Answer:
1st. 34 sq. inch
2nd. 40 sq. m
Step-by-step explanation:
for first figure,
i divide it into rectangle and triangle
rectangle = l×b = 7×4 = 28
triangle = 1/2× b×h = 1/2 × 3× 4 = 6
total= 28+6=34 sq.inch
for second figure,
I divide it into a square and two rectangles
square = 3×3= 9
1st rectangle= 4×7=28
2nd rectangle= 3× 1 =3
Total = 40 sq.m
I think correct answer is C
