Answer:
y= -3x-20
Step-by-step explanation:
°First find the gradient between the two points
Gradient= - 3
°Using the formula y= mx+c substitute the gradient into the equation. You'll get something like this: y=-3x+c
°Substitute the point (-8;4) in the above equation. You'll get something like this : 4=-3(-8) +c
°Calculate the value of c. It'll give you c=-20
°Substitute c=-20 in the equation
Final answer is y= - 3x-20
2, 7, 12
-18 + 5= -13
-13 + 5= -8
-8 + 5= (2)
2+ 5 = (7)
7+ 5= (12)
Answer:
y = 64
Step-by-step explanation:
Let's solve your equation step-by-step.
√y=8
Solve Square Root.
√y=8
y=82(Square both sides)
y=64
Check answers. (Plug them in to make sure they work.)
y=64(Works in the original equation)
If you multiply 7 * 4 it will give you the number of carnations which is 28.
