We know that an equilateral triangle has all sides equal.
Initial perimeter = s + s + s = s
Each side has been increases by then the new perimeter is:
(s+15) + (s+15) + (s+15) = 3s + 45
So the new perimeter = 3s + 45
Sparkle is longer because 464 as cm is 46.4, consequently longer thatn 46 cm.
Answer:
the answer would be 43 degrees.
Step-by-step explanation:
<span>2x+7y=-1 (1)
4x-3y=-19 (2)
multiply equation (1) by 2
4x + 14y = -2 (1')
</span>4x - 3y = -19 (2)
---------------------subtract
17y = 17
y = 1
<span>2x+7y=-1
</span><span>2x+7(1)=-1
</span>2x + 7 = -1
2x = -8
x = -4
answer
(-4, 1)
The initial value, is the value of y, when x = 0.
If you look at the graph, when x = 0, the value of y = 5. The point (0 , 5) on the graph also shows that.
So the initial value is 5
Hope this explains it.
