The slope is -1/2 and the y-intercept is -3
-Seth
Answer:
C
Step-by-step explanation:
Price of boots is represented as x, price of tennis shoes is represented as y.
x-y=44.38
x+y=196.12
Isolate x. (Or y, if you wanted to)
x=y+44.38
x=196.12-y
Set them equal to each other.
y+44.38=196.12-y
Solve for y. Then plug it in to either of the two original equations to find x.
x=120.24
y=75.86
Note: This is assuming that the boots are more expensive than the tennis shoes. If the tennis shoes are more expensive than the boots, then the prices would be switched. I didn't find this clear in your question.
To solve this question you would first multiply all the dimensions of the pillar together. That would be:
2.5 x 2.5 x 12 = 75 square feet
Then you take the weight of the pillar and divide it by the amount of square feet:
12,000 / 75 = 160 pounds per square foot.
When more offspring than can survive are produced, it is called overproduction. Variation among these offspring exists. The offspring with variations more suited to their environments will be more likely to survive.
