Answer: 2(10+5)

What is y=-10x's constant of proportionality and how would describe a graph's constant rate of change.
Fantom [35]
Okay, so here, we know that -10 is the slope, therefore, it is also the constant of proportionality. 

'x' is the unknown value, that tells us to multiply by -10. 

So, on a graph, we would consider that per unit, it would decrease by -10, since its a negative slope. 

Hope I helped, if you have further questions or concerns, feel free to PM me. Thanks! :D

Answer:

230 - 151 + 180 + (43 - 12) = 290

Step-by-step explanation:

Use PEMDAS.

Evaluate the expression in the parentheses:

230 - 151 + 180 + (43 - 12)

43 - 12 = 31

230 - 151 + 180 + 31

Add and Subtract From Left to Right:

230 - 151 + 180 + 31

79 + 180 + 31

259 + 31

290
