Answer:
A: 11,13, 290
B: 7,24,25
Step-by-step explanation:
A &B both form a right triangle not C
Answer:
a) and
Step-by-step explanation:
The idea for the solution of this equation is to find the value of c where both parts of the piecewise-defined function are the same. So we need to take the parts of the function and set them equal to each other, so we get:
and then solve for x. We move everything to one side of the equation so we get:
and we use the quadratic formula:
and we substitute:
and solve
so our two answers are:
a) and
" 2.5 times a number 'n' " = 2.5n
" 2.5n is subtracted from 6.1 " . . . . that's 6.1 - 2.5n
" the result is -11.4 " . . . . . so <u> 6.1 - 2.5n = -11.4</u>
Add 11.4 to each side : 17.5 - 2.5n = 0
Add 2.5n to each side: 17.5 = 2.5n
Divide each side by 2.5 : 7 = n
