Answer:
Step-by-step explanation:
you just need to add both equations
you will get 3y=12+6=18
3y=18
y=6
now replace y=6
3x+12=6
3x=6-12
3x=-6
x=-2
(-2,6)
Y = mx + c
m is the gradient of the graph, for each time you go across 1 x you go up y 'm' times, in your case you go up twice each time you go across once along x
c is the y intercept, the number where the y axis is cut and where you should start drawing your graph
Answer:
8
Step-by-step explanation:
First your rectangle
A = wl
A = 2 * 2
A = 4
Then one of your triangles
A = h b/2
A = 2 * 2/2
A = 2
you have 2 triangles, so the area is 4 + 4 from the rectangle
