PLEASE HELP! MATH!
t = 12r/(r+120)
t(r+120) = 120r
tr+120t = 120r
tr-120r = -120t
r(t-120) = -120t
r = -120t/(t-120)
r = 120t/(120-t)

Really need help on this please
Help! i don't understand :/
Answer:
Option C
Step-by-step explanation:
Given inequality is,
-3(2x - 4) ≤ 7(3 - x)
Solve the given inequality further,
-6x + 12 ≤ 21 - 7x
(-6x + 12) + 7x ≤ (21 - 7x) + 7x
x + 12 ≤ 21
(x + 12) - 12 ≤ 21 - 12
x ≤ 9 Or {x real | x ≤ 9}
Therefore, Option C will be the correct option.

Solve the system of equations by substitution. y = 2x y = x +1
Step-by-step explanation:
y = 2x
y = x + 1
y-1 = x
y = 2x
y = 2 (y - 1)
y = 2y - 1
y = -1

25/45
Step-by-step explanation:
Hey so can somebody help me? Please dont guest on this, im on the test and i dont want to fail, so please actually try thanks (you will get brainliest if you explain where the arrow goes and the answer of the problem) ( but the main point is to explain where the arrow goes)
Answer:
The answer would be -2 1/6
Step-by-step explanation:
The arrow goes to the left side because it is negative. -1/3 would be equal to -2/6. -5/6 + -1/6 + -1/6 = -1 1/6. Add the 1 and you get -2 1/6!
Hope this helped ^^
What is the slope of the line?
Answer:
The slope is : -2/2
Step-by-step explanation:
To find the slope, start on the y-axis. -2 passes through the line on the y-axis so start there. Go up 2 unites, which will bring you to the origin. Now you need to reach -2 on the x-axis. Go left two units, which gives you 2/2. It's rise over run. It's -2 because you went left two units not right. When you go left, or down it'll be negative.
2 = rise
/
-2 = run
(x₁,y₁) = (-2,0)

m = -1

Answer:
41
Step-by-step explanation:
y = (4*5) + 21
y = 20 + 21
y = 41
Answer: 41
Step-by-step explanation:
Basically multiply the input value by 4, since the input is x. You will have 4(5) which is 20, then add 21 to it and you have 41.
.prove that cos (90-A).sinA + sin(90 - A).cosA = 1
Answer:
See Explanation
Step-by-step explanation:
[tex]cos (90-A).sinA + sin(90 - A).cosA = 1 \\ \\ LHS = cos (90-A).sinA + sin(90 - A).cosA \\ \\ = sinA.sinA + cosA.cosA\\ \\ = sin ^{2} A + cos^{2} A \\ \\ = 1 \\ \\=RHS\\\\ reason \\ cos (90- \theta) = sin \theta \\ sin (90- \theta) = cos \theta \\ sin ^{2} \theta + cos^{2} \theta = 1 \\ \\ thus \: proved \\ [/tex]

Which equations have the same value of x as Two-thirds (6 x + 12) = negative 24? Select two options.
4 x + 8 = negative 24
9 x + 18 = negative 24
4 x = negative 16
18 x + 36 over 2 = negative 24
4 x = negative 32
Answer:
4x+8=-24 and

The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19
