Answer: 4/15ft2
Step-by-step explanation:
Area of a rectangle is
Length ×breadth
Length is 3/5
Breadth is 4/9
Area = length × breadth
Area= 3/5×4/9
Area=12/45
Divide both the numerator and denominator by 3
We have
Area= 4/15ft2
Answer:
B
Step-by-step explanation:
Answer:
y = -(x+4)² +7
Step-by-step explanation:
I find it convenient to factor the leading minus sign from the first two terms, then work with what's left.
... y = -(x² +8x) -9
Now, add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
... y = -(x² +8x +4²) -9 +4²
... y = -(x +4)² +7 . . . . . . . . . rewrite parentheses as a square; collect terms
Answer:
y = ¾x
Step-by-step explanation:
y = mx + b, where
m = slope and
b = y-intercept
If slope = ¾ and y-intercept =0, the equation is
y = ¾x
