Answer:
what i need to find there
Step-by-step explanation:
i only find y like an expression
Isolate the variable by dividing each side by factors that don't contain the variable.
y=sin(30t2hea+90)/2+1/16
R = 2x + 9y [ Given ]
When,
★ Substituting the values in the above equation
=> 13 = 2x + 9 × 3
=> 13 = 2x + 27
=> 13 - 27 = 2x
=> -14 = 2x
=> x = -14/2
=> x = -7
Answer:
y = -x - 2
Step-by-step explanation:
Find two points on the line
(0, -2)
(4, -6)
(Y2-Y1)/(X2-X1) = gradient of the line
Where (X1,Y1) = (0, -2) and (X2,Y2) = (4, -6)
(-6--2)/(4-0)
(-6+2)/4
(-4)/(4)
-1
Y = (-1)X + c
Substitute either set of coordinates in to find c.
(0, -2)
Y = (-1)X + c
-2 = (-1)0 + c
-2 = 0 + c
-2 = c
(4,-6)
Y = (-1)X + c
-6 = (-1)4 + c
-6 = -4 +c
-6 + 4 = c
-2 = c
Y = -X -2
Answer:
(4,4), (10,4), (10,10), (4,10)
Step-by-step explanation:
(2,2) x2 -> (4,4)
(5,2) x2 -> (10,4)
(5,5) x2 -> (10,10)
(2,5) x2 -> (4,10)
Hope that helps!
B. is the answer I believe since most are not functions
