Answer:
(c) will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is
So the slope of the line which is perpendicular to y = 3x+2 will be
Now (a) Line is given as its slope is so it will be not perpendicular
(b) Line is given as its slope is so it will be not perpendicular
(c) Line is given as its slope is so it will be perpendicular to the line y = 3x+2
(d) Line is given as its slope is 3 so it will not perpendicular to the line y = 3x+2
Then a dozen cases would be 78.26 dollars cause if u work it 60 divide by 8 and that times two you would get it.
Answer:
a) about -12 °C
b) see below (red line)
c) about -24.5°C
Step-by-step explanation:
a) locate the vertical line representing 10°F on the graph. Identify the point where it intersects the graphed line. Read the vertical coordinate of that point of intersection. That is the temperature in °C. (Purple line on the attachment.) It is about -12 °C.
__
b) When F = -20, C = 2F = 2(-20) = -40. So, (-20, -40) is one point on the line.
When F = 10, C = 2F = 2(10) = 20. So, (10, 20) is another point on the line.
In the attached graph, we have drawn a (red) straight line between these points.
__
c) The Celsius temperature where it is double the Fahrenheit temperature is about -24.5 °C. (Blue line on the attachment.) It is exactly -24 8/13 °C. The graph cannot be read with that precision.
Answer:
$2.25 per pound
Step-by-step explanation:
Graph attached shows the relation between the weight of the potatoes and cost of potatoes purchased.
Cost of 1 pound of potatoes will be represented by the slope of the given line.
Since slope of a line passing through two points and is given by the formula,
Slope =
Therefore, slope of the line passing through (0, 0) and (2, 4.5) will be,
Slope =
= 2.25
Therefore, cost of potatoes is $2.25 per pound.
