Step-by-step explanation:
-2(2f-4) = -4(-f+2)
Distribute the -2, multiplying it to each term inside the parentheses.
(-2 × 2f = -4f, and -2 × -4 = 8 because the double negatives cancel)
-4f+8 = -4(-f+2)
Now distribute the -4...
(-4 × -f = 4f, and -4 × 2 = -8)
-4f+8 = 4f-8
Add 4f to each side so that our variable is on just one side of the equation.
8 = 8f-8
To get rid of that -8 and isolate our variable, add 8 to each side.
16 = 8f
Divide each side by 8 to get the value of f.
2 = f
Answer: y=-.667x+1
Step-by-step explanation:
1. Firstly, substitute the coordinates of the two points into the slope intercept equation:
(1) y₁ = mx₁ + b
(2) y₂ = mx₂ + b
2. Then, subtract the first equation from the second:
y₂ - y₁ = m(x₂ - x₁)
3. Finally, divide both sides of the equation by (x₂ - x₁) to find the slope:
m = (y₂ - y₁)/(x₂ - x₁)
4. Once you have found the slope, you can substitute it into the first or second equation to find the y-intercept:
y₁ = x₁(y₂ - y₁)/(x₂ - x₁) + b
b = y₁ - x₁(y₂ - y₁)/(x₂ - x₁)
The answer is c for if you count the spaces in the half of brad, you get 4 and in half of kely, you get 8 which is a 2:1 ratio with kely and brad because kely's bigger
Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
