The graph below models the changes in temperature of a liquid during a laboratory experiment what point of the graph represents the final temperature?
Answer:
J
Step-by-step explanation:
Since the final tempurature means the final point of the line, you can see the point that ends is on (7, 0). The order for coordinate points is (x, y) and the point ends on 7 on the x-axis and 0 on the y-axis. Hope this helped!

Find value of x
Find value of y
Answer:
Step-by-step explanation:
use SOH CAH TOA
Sin = Opp / Hyp
Cos = Adj / Hyp
Tan = Opp / Adj
then we know the adjacent side and the angle, and want to find the Hyp, so use CAH
Cos(60) = ( 8[tex]\sqrt{3}[/tex] / 3 ) / Hyp ( cos(60) = 1/2 )
Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)
Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)
Hyp = 16[tex]\sqrt{3}[/tex] / 3
x = 16[tex]\sqrt{3}[/tex] / 3
Now use SOH
Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3 ( sin(60) = [tex]\sqrt{3}[/tex]/2 )
(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp
16 * 3 / 6 = Opp
8 = Opp
y = 8

Jaylen's bed is six feet long and his desk is three feet long. He wants to leave a two-foot space between his bed and desk. If there are 125 inches available along the wall, is there enough room for Jaylen to fit his bed and desk? Justify your reasoning using words, numbers, or pictures.
Answer: Not possible
Step-by-step explanation:
Given
The length of Jaylen's bed is [tex]6\ ft\approx 72\ in.[/tex]
The length of his desk is [tex]3\ ft\approx 36\ in.[/tex]
The total length along the wall is [tex]125\ in.[/tex]
Jaylen wants [tex]2\ ft \approx 24\ in.[/tex] gap between bed and desk
the combined length of bed and desk is
[tex]\Rightarrow 72+36=108\ in.[/tex]
The remaining length after placing the bed and desk is
[tex]\Rightarrow 125-108=17\ in.[/tex]
As the remaining length is less than the required length
Therefore, it is not possible to leave a gap of two-foot between the bed and desk

Answer:
Correct: a, b, c, d, f, g, h, i, l
Incorrect: e, j, k
Step-by-step explanation:
a. -120=60(-2) {insert x and y into the equation and see if it works} Correct
b. 60 is being multiplied by hours, so it is the mph Correct
c. 60 is always the one being multiplied, so it's the constant Correct
d. 210=60(3.5) {insert 3.5 as x [cause hours] and see if it equals 210 [it does]} Correct
e. y is the dependent variable, and it represent miles driven Incorrect
f. Direct variation equation is y=kx {in the equation, k=60} Correct
g. x is the independent variable, and it represents the hours driven Correct
h. The x and the y are proportional Correct
i. y is the dependent variable, and it represent miles driven Correct
j. y is the dependent variable, and it represent miles driven Incorrect
k. Rise=y Run=x The first point would be (1,60) {rise=60 run=1} Incorrect
l. (0,0) is a solution, and it is also the y-intercept Correct

Answer for brainliest
Answer:
x=2 y=−1 so (2,-1)
Step-by-step explanation:
2x+y=3
x=3y+5
Consider the second equation. Subtract 3y from both sides.
x−3y=5
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the results for that variable in the other equation.
2x+y=3,x−3y=5
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
2x+y=3
Subtract y from both sides of the equation.
2x=−y+3
Divide both sides by 2.
x=1/2(−y+3)
Multiply 1/2 times −y+3.
x=−1/2y+3/2
Substitute y+3/2 for x in the other equation, x−3y=5.
−1/2y+3/2−3y=5
Add −y/2 to −3y.
−7/2y+3/2=5
Subtract 3/2 from both sides of the equation.
−7/2y=7/2
Divide both sides of the equation by −7/2, which is the same as multiplying both sides by the reciprocal of the fraction.
y=−1
Substitute −1 for y in x=−1/2y+3/2. Because the resulting equation contains only one variable, you can solve for x directly.
x=−1/2(−1)+3/2
Multiply −1/2 times −1.
x=1+3/2
Add 3/2 to 1/2 by finding a common denominator and adding numerators. Then reduce the fraction to the lowest terms if possible.
x=2
The system is now solved.
x=2,y=−1

what is the measure of angle b
Answer:
34
Step-by-step explanation:
A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34
So the answer is 34
Answer:
b = 34 degrees
Step-by-step explanation:
*triangles have an interior angle of 180 degrees
to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:
⇒ 180 - (115 + 31)
solve:
⇒ 180 - 146 = 34
b = 34
Here are the answer choices pls hurry thank you

your answer for this question will be the 3rd answer choice
Find the value of x.
Answer:
80°
Step-by-step explanation:
42° + 58° + x = 180° [Angle sum property of triangle]
=> 100 + x = 180
=> x = 180 - 100
=> x = 80 (Ans)
Step-by-step explanation:
58° + 42° + x = 180° -- (Δ sum property)
100° + x = 180°
x = 180° - 100°
x = 80°

I need help and please give me an understandable answer because I need to go to bed right now. I used 31 and 40 feet and none of them worked
Answer:
35 feet
Step-by-step explanation:
We'll begin by calculating the resultant for you and your friend.
For you:
R² = 12² + 9²
R² = 144 + 81
R² = 225
Take the square root of both side
R = √225
R = 15 feet
For your friend:
R² = 16² + 12²
R² = 256 + 144
R² = 400
Take the square root of both side
R = √400
R = 20 feet
Finally, we shall determine the distance between you and your friend.
The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e
You resultant = 15 feet
Your friend's resultant = 20 feet
Distance between you and your friend = 15 + 20 = 35 feet.
Therefore, you threw the baseball 35 feet away from your friend.
Tell whether the ordered pair is a solution of the equation. y = x - 5; (6, 11)
Answer:
Not a solution
Step-by-step explanation:
y=x-5
Plug in the point (6,11)
11=6-5
11=1
11≠1
Because the left side of the equation and the right side aren't equal, the ordered pair (6,11) is not a solution to the equation y=x-5.
I hope this helps!
Answer:
It isn't a solution of the equation.
Step-by-step explanation:
(x, y) = (6, 11)
You replace the values ok the equation:
11=6-5
11=1 Which is FALSE so it isn't a solution of the equation.
