Step-by-step explanation:
3x+7y=12
-7y -7y
3x=-7y+12
/3 /3
x=-7/3y+4
Answer:
X=4
Step-by-step explanation:
You make y 0 to find x so
3(4) + 7(0) =12
12+0=12

Answer:
[tex]f(x)=4^{2x}[/tex]
Step-by-step explanation:
So we are given:
[tex]f(x)=(8^{\frac{2}{3}x})(16^{\frac{1}{2}x})[/tex]
and we have to find a function that will produce a similar graph. To do this, lets first simplify the given function.
Here are some properties of exponents that I will be using:
[tex]c^{\frac{n}{x}}=\sqrt[x]{c^{n}}=(\sqrt[x]{c})^{n}[/tex]
[tex](c^{x})^{n}=(c^{n})^{x}=c^{xn}[/tex]
[tex]c^{x}*c^{n}=c^{x+n}[/tex]
Now lets begin simplifying the function.
[tex]f(x)=(8^{\frac{2}{3}x})(16^{\frac{1}{2}x})[/tex]
[tex]=((\sqrt[3]{8^{2}})^{x})((\sqrt{16})^{x})[/tex]
[tex]=(4^{x})(4^{x})[/tex]
[tex]=4^{2x}[/tex]
So the correct answer would be [tex]f(x)=4^{2x}[/tex].
I hope you find my answer and explanation to be helpful. Happy studying.

(x-3)^2+(y+4)^2=36 geometry
Answer:
Simplifying
(x + -2) * 2 + (y + -4) * 2 = 36
Reorder the terms:
(-2 + x) * 2 + (y + -4) * 2 = 36
Reorder the terms for easier multiplication:
2(-2 + x) + (y + -4) * 2 = 36
(-2 * 2 + x * 2) + (y + -4) * 2 = 36
(-4 + 2x) + (y + -4) * 2 = 36
Reorder the terms:
-4 + 2x + (-4 + y) * 2 = 36
Reorder the terms for easier multiplication:
-4 + 2x + 2(-4 + y) = 36
-4 + 2x + (-4 * 2 + y * 2) = 36
-4 + 2x + (-8 + 2y) = 36
Reorder the terms:
-4 + -8 + 2x + 2y = 36
Combine like terms: -4 + -8 = -12
-12 + 2x + 2y = 36
Solving
-12 + 2x + 2y = 36
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + 2x + 12 + 2y = 36 + 12
Reorder the terms:
-12 + 12 + 2x + 2y = 36 + 12
Combine like terms: -12 + 12 = 0
0 + 2x + 2y = 36 + 12
2x + 2y = 36 + 12
Combine like terms: 36 + 12 = 48
2x + 2y = 48
Add '-2y' to each side of the equation.
2x + 2y + -2y = 48 + -2y
Combine like terms: 2y + -2y = 0
2x + 0 = 48 + -2y
2x = 48 + -2y
Divide each side by '2'.
x = 24 + -1y
Simplifying
x = 24 + -1y

Use 2 to 3 sentences to name two pairs of corresponding angles and explain the difference between corresponding angles and same-side interior angles.
Answer:
Two pairs of corresponding angles are 1 and 5 also 3 and 7.
Difference:
The angles are on the SAME SIDE of the transversal, one INTERIOR and one EXTERIOR, but not adjacent. The angles lie on the same side of the transversal in "corresponding" positions. If two parallel lines are cut by a transversal, the corresponding angles are congruent.

In Neil's city, the temperature is 72.6 degrees and is rising 1.3 degrees each hour. In Sheppard's city, the temperature is 80.4 degrees and is dropping 1.82 degrees each hour. In how many hours will the temperature in Neil's city be no less than the temperature in Sheppard's city?
Answer:
2.5 hours
Step-by-step explanation:
Given that :
Temperature in Neil's city :
72.6° and rising by 1.3° per hour
Temperature in Sheppard's city :
80.4° and dropping by 1.82° per hour
In how many hours will the temperature in Neil's city be no less than the temperature in Sheppard's city
Let number of hours = h
Hence, Neil city :
72.6 + 1.3h
Sheppard city:
80.4 - 1.82h
72.6 + 1.3h ≥ 80.4 - 1.82h
1.3h + 1.82h ≥ 80.4 - 72.6
3.12h ≥ 7.8
h ≥ 2.5

2w2 - W - 28 = 0
What is the answer to this??
Answer:
w = 4 or w=-3.5
Step-by-step explanation:
This likely factors into
(2w + 7)(w - 4) = 0
in which case there are 2 factors.
2w + 7 = 0
w = - 3.5 or
w - 4 = 0
w = 4

The selling price of a watch is Rs. 595. If the watch was
sold at 15% discount on the marked price, Find the market
price of the watch.
Answer:
Rs 700
Step-by-step explanation:
If S.P = 595
discount = 15%
Then C.P = 100/100 - 15×595
= Rs 700.

Evaluate each of the following given the function definitions and input values. Show your work.
f(x)=3x+7
g(x)=3x²
h(x)=√x-5
1. f(−4) =
2. f(2) =
3. g(2) =
4. g(-3) =
5. h(41) =
6. h(14) =
F(x) = 3x^2 + 1, G(x) = 2x - 3, H(x) = x
F(3) = 3(3)^2 + 1 = 27 + 1 = 28
G(4) = 2(4) - 3 = 8 - 3 = 5
2H(5) = 2(5) = 10
F(3) + G(4) - 2H(5) = 28 + 5 - 10
F(3) + G(4) - 2H(5) = 23
question 2
Given: F(x) = 5x - 6 and G(x) = x - 4
(FoG) (x) = F(G(x)) = 5(x-4) - 6
= 5x - 20 - 6
= 5x - 26
Inverse
x = 5y - 26
5y = x + 26
y = x/5 + 26/5
So
(FoG) -1 (x) = x/5 + 26/5
