Answer:
Part A: y=4.50x+6
Part B: $46.50=4.50(9)+6
Marc can buy up to 9 sandwiches ($40.5) plus chips ($6) without going over $50.
Answer:

Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula
. Pick two points on the line and substitute their x and y values into the formula, then solve. I used the points (-5,-4) and (0,-6):
So, the slope of the line is
.
2) Next, use the point-slope formula
to write the equation of the line in point-slope form. (From there, we can convert it to slope-intercept form.) Substitute values for the
,
and
into the formula.
Since
represents the slope, substitute
in its place. Since
and
represent the x and y values of one point on the line, pick any point on the line (any one is fine, it will equal the same thing at the end) and substitute its x and y values in those places. (I chose (0,-6), as seen below.) Then, with the resulting equation, isolate y to put the equation in slope-intercept form:

Answer:
<h2>84.78</h2>
Step-by-step explanation:
We have the area of a circle

The sector with a central angle of

Calculate, what part of 360° is an angle 120°:

The same part of an area of a circle is an area of a segment.
Therefore:

Use π ≈ 3.14

Answer:
nine hundred thirty-eight one hundred twenty thousandths
Step-by-step explanation:
Basically all you need to do is estimate what 32.7 x 2.8 is. If what you get is close to 91.56, then Tom's answer is reasonable. If what you get is not close to 91.56, then his answer is not reasonable. Do you know how to estimate by rounding?
