Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot
1) first step
you must do( a+b) ^2 = a^2+2ab+b^2
then
2)second step
y = -3(x+1)^2 +4 = -3( x^2+2x+1) +4⇒ y = -3x^2-6x-3 +4, y = 3x^2-6x+1
now the graph of this function is
Another way to express it would be -12x+28
Remember, x^-1=1/x
so
f(-1)=4(7)^-1=4(1/7)=4/7
f(2)=4(7)^2=4(49)=196
Answer:
The equation of the line would be y = -6x + 22
Step-by-step explanation:
When you have the slope and the intercept of a line, all you need to do to find the form of the line is use the base formula and plug in the two values.
y = mx + b
y = -6x + 22
