S = -2-4r. You can't simplify the expression past that.
Answer:
y = 55
Step-by-step explanation:
The sum of the angles of a triangle are 180
40 + y+30 + y = 180
Combine like terms
70 +2y = 180
Subtract 70 from each side
2y = 180-70
2y = 110
Divide each side by 2
2y/2 = 110/2
y = 55
His answer was wrong. The correct answer would be 129,000
Explain: 500 rounded to the nearest thousand would be 1000
But 499 rounded to the nearest thousand would not become 1000
y = 2x - 1
Lets see something:
y = 2x - 1
y = f(x)
If we want to do translations in vertical we just have to add an constant, where postive moves it upward and negatives, downward
y = f(x) + c
y = f(x) - 1
y = 2x - 1 - 1
y = 2x - 2
Now let's see this translation to the right
If we want to translate it in horizontal we just have to add a constant inside the function, where positive moves it to the left, and negative to the right
y = f(x) - 1
y = f(x - 3) - 1
y = 2.(x - 3) - 1 - 1
y = 2x - 6 - 2
y = 2x - 8
