Answer:
Rock costs $3.20 per pound.
Step-by-step explanation:
Because sand costs three times as much as rocks per pound, you can determine the cost of rocks per pound by dividing the cost of sand per pound by three:
The answer is -6+x=8. x is the unknown number. To find the distance, try to use a number line. And the answer to the expression is 14. To get from -6 to 0, you add 6. Then from 0 to 8, you add 8. 8+6=14
You can find the slope of this line directly from the graph. The "run" from -2 to 0 is 2, and the "rise" (actually, a drop) from 4 to 1 is -3. Thus, the slope is -3/2.
Eliminate the 2nd answer possibility; its slope is wrong.
The point-slope form of the eq'n of a str line is
y-k = m(x-h) Compare this to the first answer possibility:
<span>y + 5 = -3/2(x - 4). Recognize that k= -5 and h=4.
Check: does the point (4,-5) lie on the given line?
Yes. Thus, this is the correct formula.</span>
Let x be the length of the base and let y be the total
y= 3x-2
