Answer:
x=4
Step-by-step explanation:
distribute first 3x+18-13=17
combine like terms 3x+5=17
subtract 5 from both sides 3x=12
divide 3 from both sides x=4

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.
A cereal company made a batch of 714 ounces of cereal. If they put it in 18-ounce boxes, how many boxes would the batch fill?

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.

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!
Unit 4 Test, Part 2: Congruence and Constructions
Help with my math please
Answer/Step-by-sep explanation:
1. Given:
∆NMK ≅ ∆TRP
[tex] \overline{NM} = 20 [/tex]
[tex] \overline{MK} = 15 [/tex]
[tex] \overline{KN} = 25 [/tex]
[tex] \overline{TR} = 3x - 1 [/tex]
a. To complete the congruent statement, thus: ∆MNK ≅ ∆RTP
b. The side that is congruent to [tex] \overline{TR} [/tex] is [tex] \overline{NM} [/tex]. Thus:
[tex] \overline{TR} [/tex] ≅ [tex] \overline{NM} [/tex]
c. Since [tex] \overline{TR} [/tex] ≅ [tex] \overline{NM} [/tex], therefore:
[tex] \overline{TR} = \overline{NM} [/tex]
[tex] 3x - 1 = 20 [/tex] (substitution)
Add 1 to both sides
[tex] 3x = 20 + 1 [/tex]
[tex] 3x = 21 [/tex]
Divide both sides by 3
[tex] x = \frac{21}{3} [/tex]
[tex] x = 7 [/tex]
2. a. Slope of LK = [tex] \frac{rise}{run} = \frac{4}{3} [/tex]
Slope of LM = [tex] \frac{rise}{run} = -\frac{3}{5} [/tex]
b. ✍️Length of LK is the distance between L(-7, 4) and (-4, 8):
[tex] Lk = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] Lk = \sqrt{(-4 -(-7))^2 + (8 - 4)^2} [/tex]
[tex] Lk = \sqrt{(3)^2 + (4)^2} [/tex]
[tex] Lk = \sqrt{9 + 16} [/tex]
[tex] Lk = \sqrt{25} [/tex]
[tex] Lk = 5 [/tex]
✍️Length of LM is the distance between L(-7, 4) and (-2, 1):
[tex] LM = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] LM = \sqrt{(-2 -(-7))^2 + (1 - 4)^2} [/tex]
[tex] LM = \sqrt{(5)^2 + (-3)^2} [/tex]
[tex] LM = \sqrt{25 + 9} [/tex]
[tex] LM = \sqrt{34} [/tex]
[tex] LM = 5.8 [/tex] (nearest tenth)
∆KLM is not an isosceles ∆ because it does not has two equal side lengths. This we can see because LK and LM are not equal.
Therefore, Anthony is incorrect. Am isosceles ∆ has two equal sides.
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

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.
