Dunno what the RACE method is, never heard of it before but.
3x is positive, has a variable.
-3 is negative, has no variable.
-3x^2 is negative, has a variable, and an exponent.
-5x is negaitive, has a variable.
Answer:
y = 7/x
Step-by-step explanation:
y = k/x
1/5 = k/35
(1/5)(35) = k
k = 7
189/1000 would be the answer
Answer:
a) scale factor = 1.5
b) d length is 7.5
c) Area scale factor is 2.25
Step-by-step explanation:
Given QR =6
And ST =9
Length Scalar factor = enlarged length /previous length
=9/6
=1.5
Length Scalar factor =1.5
b)we know PS enlarged length of PQ
Length scale factor = PS/PQ
1.5 =PS/5
PS =5×1.5
PS =d =7.5
d length is 7.5
c)Formula :
Area scale factor = (length scale factor)2
=(1.5)2
=2.25
Area scale factor is 2.25
