Answer:
15
Step-by-step explanation:
Answer:
a) 1/12
b) 3/4
c) 2/35
d) 20
e) 3/10
Step-by-step explanation:
a) 8x=2/3
x=(2/3)/8=1/12
b) 3/2=2x
x=(3/2)/2=3/4
c) 5x=2/7
x=(2/7)/5=2/35
d)1/4x=5
x=5/(1/4)=20
e)1/5=2/3x
x=(1/5)/(2/3)=3/10
4z-20+2=4z-18
4z-18=4z-18
Their answer is the same no answer for this .. or maybe you forgot to wrote an other thing... I hope that I could help you!! :)
A square with a side length of 4 would have an area of 16 because 4x4 equals 16.
The gradient of the function is constant s the independent variable (x) varies The graph passes through the origin. That is to say when x = 0, y = 0. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear. I believe the answer is C. Hope I helped!
