56 is the slope
and -4 is the y intercept
so you first graph 0,-4
then use the slope and move 56 units up and one to the right
The square divided into 2 equal isosceles triangles which are 45 45 90.
The diagonal is the hypotenuse of the triangles
Given leg = 11
Ratio of leg: hypotenuse = x : x√2
So if leg x = 11 the hypotenuse = 11√2
Answer is E. 11√2
P = 2(L + W)
P = 120
W = 20
120 = 2(L + 20)
120 = 2L + 40
120 - 40 = 2L
80 = 2L
80/2 = L
40 = L
check..
120 = 2(40 + 20)
120 = 2(60)
120 = 120 (correct)
so the length of the garden (L) = 40 yds
Answer:
The y - intercept is (0, 4)
Step-by-step explanation:
The equation x + 4y = 8 is in 'standard form.' Any line parallel to this line has an equation that looks exactly the same EXCEPT for the constant.
So, let's write out x + 4y = 8 and replace the 8 with C.
x + 4y = C
Now take the coordinates of the given point (4, 3) and substitute them into the above equation: 4 + 4(3) = C = 16
Thus, the equation of the line passing through (4, 3) is x + 4y = 16.
To find the y-intercept, set x = 0 and calculate y:
0 + 4y = 16, or y = 4
The y - intercept is (0, 4)
