9/4 = 2 1/4
1/4 = 0.25
2.25 is your answer
hope this helps
I got (3,0) and (1,2), i don't know if that's what it is asking.
7. the wall is 12 the ladder is 15 find the ground
this will make a right angle from the wall and the ground
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 both sides
b^2=81
square root both sides
b=9 ft
8. area of square is s^2
s^2=81
square root both sides s=9cm
diagonal=
a^2+b^2=c^2
9^2+9^2=c^2
81+81=c^2
162=c^2
square root both sides
12.73cm is diagonal
9. a^2+b^2=c^2
a=9
b=12
c=
9^2+12^2=c^2
81+144=c^2
225=c^2
square root both sides
c=15km

I have no clue to be honest
Answer:
Step-by-step explanation:
-3x + 3y = 6.......(1)
y= 4x + 5............(2)
Putting (2) in (1)
-3x + 3(4x + 5) = 6
-3x + 12x + 15 = 6
9x = 6 -15
9x = -9
x = -9/9
x = -1
Putting x in (2)
y= 4x + 5
y = 4(-1) + 5
y = -4 + 5
y = 1
