Answer:
Step-by-step explanation:
Okay so you are gonna substitute x for 5 so the equations will look like y= (5)2+(5)2
So 10+10 = 20
So y=20
Answer:
13+Z=-6

Temperature dropped by 28°C in two hours
Answer:
x =0,1,2,3,4,5,6
P(x) =0,4,8,12,16,20,24
Step-by-step explanation:
P(x)= 4x
4 x 1 = 4
4 x 2 = 8
4 x 3 =12
4 x 4 = 16
4 x 5 = 20
4 x 6 = 24
Answer:
x= - 50/9
Step-by-step explanation:
multipy both equations by 12
9x+60=10
then move the constant to the right hand side and change it's sign
9x= 10 - 60
calculate difference
9x = -50
divide both sides by 9
x= - 50/9
