Consecutive numbers are always 1 away from each other
3,4
so consecutive is represented by
x and x+1
so sum is -171
x+x+1=-171
add like terms
2x+1=-171
subtract 1 from both sides
2x=-172
divide both sides by 2
x=-86
subustitute
x+1=otehr number
x+1=-86+1=-85
answer is -85 and -86
A) 2y = f(x) ⇒ y =
f(x) → This is a vertical shrink by a factor of ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
B) y = f(2x) → This is a horizontal shrink by a factor of ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Answer:
j(-2) = i√2 + 6
Step-by-step explanation:
√-1 = imaginary number i
Step 1: Define
j(x) = √x + 6
k(x) = 9 - x
k(11) = x = 11
Step 2: Find k(11)
k(11) = 9 - 11
k(11) = -2
Step 3: Find j(-2)
j(-2) = √-2 + 6
j(-2) = √-1 · √2 + 6
j(-2) = i√2 + 6
Answer:
x^2 +y^2 = 25
Step-by-step explanation:
-3^2 +4^2= 25
Answer:
x =2
Step-by-step explanation:
-2(1 - 4x) = 3x + 8
Distribute
-2 +8x = 3x +8
Subtract 3x from each side
-2 +8x-3x = 3x-3x +8
-2+5x = 8
Add 2 from each side
-2+2 +5x = 8+2
5x = 10
Divide by 5
5x/5 = 10/5
x =2
