Answer:
The equation of the line is y = 1/4x - 4
Step-by-step explanation:
In order to find this, start with two points that are on the line. We'll use (0, -4) and (4, -3). Now we can use the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-4 - -3)/(0 - 4)
m = -1/-4
m = 1/4
Now that we have this, we can use that slope and a point in point-slope form. Then we solve for y to get the equation.
y - y1 = m(x - x1)
y - -4 = 1/4(x - 0)
y + 4 = 1/4x
y = 1/4x - 4
42/1 because it's a whole number so the denominator is a 1
The cladogram that shows the relationship between the organisms is <em>Option D</em>, as attached.
<em>Option D</em> of the attached cladogram shows that birds and reptiles are related since both lay hard-shelled eggs. It also shows the relationship between birds, reptiles, and frogs, which each have four limbs. Finally, birds, reptiles, frogs, and fish with jaws are related. Note that the bird's wings are regarded as limbs.
Thus, the cladogram that depicts the relationship among these organisms is <em>Option D.</em>

Answer:
part A: 10.52
part B: 67.33
Step-by-step explanation:
part a:52.60 x 0.20=10.52
part b:52.60 x 0.08=4.2080
4.2080 about equal to 4.21
52.60 x 0.20=10.52
the amount of the bill before tax = 52.60
52.60+4.21+10.52=67.33
