Y = 25x + 35
y = 5x + 45
Thus,
25x + 35 = 5x + 45
25x - 5x = 45 - 35
20x = 10
x = 10/20 = 1/2
y = 5x + 45
y = 2.5 + 45
y = 47.5
Thus, x = 1/2, y = 47.5
Answer:
AC = 10
Step-by-step explanation:
This is a right triangle
use the pythagorean theorem
a² + b² = c²
6² + 8² = c²
36 + 64 = c²
100 = c²
Take the square root of both sides
10 = c
AC = 10
The correct answer is 10 not 12
It’s y = 1 + 3x bcuz the 3 is in the x axis which should be as a whole together while the 1 is on the y which is why it’s equaled to it.
Answer:
C
Step-by-step explanation:
The surface are of the prism will be the area of a each side added together. The work would look like this:
SA = 2[(l×h)+(l×b)+(b×h)]
SA = 2(lh+lb+bh)
But if you multiply each dimension by 5, the area becomes
SA = 2[(5l×5h)+(5l×5b)+(5b×5h)]
SA = 2(5²lh+5²lb+5²bh)
SA = 5²×2(lh+lb+bh)
SA = 5²area
Since 5² = 25, then the the surface area is multiplied in size by 25.
