Answer:
Step-by-step explanation:
Let the loaves sold be 
and rolls sold be 
.
Given:
Cost for 1 loaf of bread = $3
∴ Cost of loaves of bread = 
Cost of 1 roll of bread = $1
∴ Cost of rolls = 
Total cost of the baked goods = $24
Therefore, as per question,
Now, the graph is shown below.
The vertical axis represent the rolls sold and the horizontal axis represent the loaves sold.
Draw a horizontal line from 12 mark on the vertical axis to the given line to meet at point A. Now, from point A, draw a vertical line to meet the horizontal axis at point B. Point B is the number of loaves sold.
From the graph, loaves sold are 4 when rolls sold are 12.

Answer:
is the fourth one
Step-by-step explanation:
just replace x with the numbers given
and then work it out.
y=x-5
y=1-5=-4
y=2-5=-3
and so on
hope this helps
Answer:
12 ft
Step-by-step explanation:
P=2L+2w
56=2(w+4)+2w
56=2w+8+2w
56=4w+8
4w=48
w=12
Answer:
119.05°
Step-by-step explanation:
In general, the angle is given by ...
θ = arctan(y/x)
Here, that becomes ...
θ = arctan(9/-5) ≈ 119.05°

<em>Comment on using a calculator</em>
If you use the ATAN2( ) function of a graphing calculator or spreadsheet, it will give you the angle in the proper quadrant. If you use the arctangent function (tan⁻¹) of a typical scientific calculator, it will give you a 4th-quadrant angle when the ratio is negative. You must recognize that the desired 2nd-quadrant angle is 180° more than that.

It may help you to consider looking at the "reference angle." In this geometry, it is the angle between the vector v and the -x axis. The coordinates tell you the lengths of the sides of the triangle vector v forms with the -x axis and a vertical line from that axis to the tip of the vector. Then the trig ratio you're interested in is ...
Tan = Opposite/Adjacent = |y|/|x|
This is the tangent of the reference angle, which will be ...
θ = arctan(|y| / |x|) = arctan(9/5) ≈ 60.95°
You can see from your diagram that the angle CCW from the +x axis will be the supplement of this value, 180° -60.95° = 119.05°.
