Answer:
y = 0,5 x + (-3)
Step-by-step explanation:
We can see from the graph that when y = -3, the line crosses y axis, therefore
y = ? x + (-3)
We can also spot that when x = 6, y = 0
// now mark ? sign as a variable k and put the given x and y values into the previous expression
y = k * x - 3
0 = k * 6 - 3
k * 6 = 3
k = 3/6
k = 0,5
Answer:
103
Step-by-step explanation:
108+85+94+103+112+115+98+119+126+105+82+89=1236
1236/12=103
Answer:
Step-by-step explanation:
We can use the process of elimination as
5x + 4y = 24
5(x + 7y = 11) —> 5x + 35y = 55
5x + 4y = 24
-(5x + 35y = 55)
—————————
-31y = -31
-31y/-31 = -31/-31
y=1
$=(a^2-10a)-(b^2+6b) +16$
$=[(a^2-2(5)a+25)-25]-[(b^2+2(3)b+9)-9]+16$
$=(a-5)^2-25-(b+3)^2+9+16$
$=(a-5)^2-(b+3)^2$
