Answer:
2
Step-by-step explanation:
2 x 3= 6
6 divided by 3 = 2
2 - 5 = -3 because it takes the sign of the larger number
Answer:
y = 1/3 x + 4
Step-by-step explanation:
y = 1/3 x + 4
The y intercept is 4 (when x = 0 from the graph) and the slope is rise (1) and run (3).
Answer:
The perimeter would also be multiplied by 2.
Step-by-step explanation:
The perimeter would also be multiplied by 2. Suppose the sides of a triangle are 5, 10 and 13. The perimeter would be the sum of the side lengths or 5 + 10 + 13 = 28 ft.
Multiply each side length so 5*2 = 10, 10*2 = 20 and 13*2 = 26. Find the perimeter by finding their sum, 10 + 20 + 26 = 56.
Divide the new perimeter by the old perimeter to find a scale factor.
56/28 = 2.
The new perimeter is exactly 2 times bigger since 2*28 = 56.
Answer:
x = y
Step-by-step explanation:
Add y to both sides of the equation:
x - y + y = 0 + y
x = y . . . . . simplify
5a - 4a = -9 - 8a
a = -9 - 8a
9a = -9
a = -1
