Answer:
22.3
Step-by-step explanation:
divide 13/7 = 1.86
multiply 1.86x12 = 22.3
To find these two lets convert this into slope-intercept form:
-7x + 7y = -17
7y = 7x -17
y = x - 17/7
So, the slope is 1 and the y-intercept is -17/7
Hope this helps!
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k =
=
= 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
X^4+y^4=81
there are 2 solutions
x=0 x=3
y=3 or y=0
f(x,y)=3^2+0^2=9 is a constant who has the graph a line || Ox
