you might think that SSA is also doable because there is a right angle in both triangles but it is not
a way to remember this is that "there are no donkeys in geometry" because SSA backwards is another word for donkey

Find the slope of the line.
- 1/3
-3
4
1/4
Answer:
-3
Step-by-step explanation:
First, we find points on the line, (1,1) and (4,1). Then we can use the slope formula, (y2 - y1)/(x2-x1). Plugging those two points into the formula gives -3/1 which is equal to -3.
The discriminant of a quadartic equation is 40. What is the nature of the solutions?
Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
The nature of the solution of positive discriminant of a quadratic equation shows two distinct real number solutions.
Here discriminant of a quadratic equation is 40.
What is discriminant?
The discriminant is the part of the quadratic formula underneath the square root symbol; [tex]b^{2} -4ac[/tex]. The discriminant tell us whether there are two solution, one solution, or no solutions.
Now, since the discriminant is given as 40 that's mean discriminant is positive.
Hence we have two distinct real number solutions.

A study found that 27% of the fish in a river are trout, 36% are salmon, and 18% are sturgeon. If a large fish trap is set and it captures 200, what is the ratio of salmon to total fish, in lowest terms
Answer:
The ratio of salmon to total fish caught is 9 over 25.
Step-by-step explanation:
Start with what we know. We have 200 total fish caught and 36% are salmon. The rest is just mumble jumble so don't pay attention to that.
All we have to do is find 36% of 200, and the easiest way to do that is by first knowing that 36% of 100 is 36 so if we double that it will give us 36% of 200.
36 x 2 = 72
So, the ratio of salmon to total fish caught is 72 over 200. But, in simplest form is 9 over 25 because 72/200 divided by 4/4 = 9/25.
Hope this helps! If you have any additional questions please don't hesitate tp ask me or your teacher to be sure you really master this subject. Stay safe and please mark brainliest!

an internet service provider chargers $18 per month plus an initial set up fee. One customer paid a total of $81 after 2 months. Write an equation modeling this situation on slope- intercept form.
Answer:
y = 18x + 45
Step-by-step explanation:
81 = 18x + b
81 = 18(2) + b
81 = 36 + b
b = 45 so 45$ is the initial set up fee

Answer:
P = 250 +50t
Step-by-step explanation:
We are given two pairs of time and price:
(t, P) = (0, 250) and (5, 500)
We can put these into the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (500 -250)/(5 -0)(t -0) +250
P = 250/5t +250
P = 50t +250 . . . . Madelyin's cost equation

Answer:
[tex]B=\frac{2A}{h}-b[/tex]
Step-by-step explanation:
To solve this B needs to be isolated. First we must multiply both sides of the equation by 2 to get rid of the fraction on the left side. Next, divide both sides by h to get rid of the h on the left side. Finally, subtract b form both sides to get B by itself.
