<span>x+9=2x+1
Since both equations give the value of y, therefor y = y. You simply substitute y with its corresponding equation.
y = y
x + 9 = 2x + 1 *we need to find the value of x to get the value of y.
x - 2x = 1 - 9
-x = -8
-1x/-1 = -8/-1
x = 8
Substitute x with its value to get y.
Equation S: y = x + 9 </span>⇒ y = 8 + 9 ⇒ y = 17
Equation T: y = 2x + 1 ⇒ y = 2(8) + 1 ⇒ y = 16 + 1 ⇒ y = 17
<span>x+9=2x+1
</span>17 = 17
Answer:
6.89
Step-by-step explanation:
(6.89+14.52)+(-14.52)
=6.89+14.52-14.52 First take away the parenthesis
=6.89 The positive and negative 14.52 cancel out
Answer:
see explanation
Step-by-step explanation:
The average rate of change over the closed interval [ a, b ] is
here [ a, b ] = [ 0, 8 ]
f(b) = f(8) = 
= 
= 
f(a) = f(0) = 
= 
f(b) - f(a) = - = 
average rate of change = 
= 
Answer: it should be 28
Step-by-step explanation: because the way the other problems are solved is the right side of the triangle times the bottom and then adding the left side of the triangle, ( 9x8+7=79 ) ( 5x5+5=30) so to get the answer you’d just multiply 24x3= 72 , then subtract 100-72= 28
