Please help me. I can't draw the graph lines correctly on this.

  see below

Step-by-step explanation:

It is generally convenient to start at the y-intercept and use the slope to count squares for rise and run.

First equation

The y-intercept is -3. The ratio of rise to run is 1/4, so the dashed line will go up 1 square for each 4 squares to the right. To the left, it will go down 1 square for each 4 squares to the left. Since the inequality is y > ( ), the shading will be above the (dashed) line.

Second equation

The y-intercept is 0. The ratio of rise to run is -1/2, so the solid line will go down 1 square for each 2 squares to the right. To the left, it will go down 1 square for each 2 squares to the left. Since the inequality is y ≥ ( ), the shading will be above the (solid) line.

Comment on accurate drawing

For good accuracy, it is usually convenient to draw the boundary lines between points close to the edge of the graph. The first equation is a little tough that way because there aren't two sets of 4 squares between the y-axis and the edge of the graph.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
