Answer:
B Mina, because for every 4-unit increase in x, there is an increase in y by 2
Step-by-step explanation:
This is a linear function because the change rate is regular from one point to the next.
The X values go -12, -8, -4, 0
The Y values go -8, -6, -4, -2
You can also verify it's linear by calculating the slope at two different locations. The slope between the first two pairs (-12,-8) and (-8,-6) equals to 2. Same goes for the other pairs... so, since it has a steady slope, it's linear.
Answer:
36
8 times 9 equals 72 and then you just divide that by two and it would be 36
The answer is B
-6+[4-(x-2)]
-6+4-x+2
-x
Hi there, Rukie! This problem can be solved by divided the number given by one of the ratios, and multiplying that answer by the other ratio. Since Bob invested the greater amount, we can divide his investment ($450) by 8, getting the answer of 56.25 (that's the unit of the ratio). We can then multiply that number by 7 to calculate Ellen's investment, which comes out to be $393 dollar and 75 cents. Hope that helps!
