x=4.80989686
by simplifying both sides of the equation, then isolating the variable.
Answer:
x= - 9
Step-by-step explanation:
This problem bothers on the law of indices
Given the expression
3^4x=27^x-3
We can also simplify it using the law
3^4x= 3^3(x-3)
Equating the powers we have
4x= 3(x-3)
Opening bracket
4x= 3x-9
Collecting like terms we have
4x-3x=-9
x=-9
Indices are used to show numbers that have been multiplied by themselves. They can also be used to represent roots, such as the square root, and some fractions. The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full.
B=pw+p, for w. What is the solution for w?
Answer:
B/p -1 =w
Step-by-step explanation:
B=pw+p
Subtract p from each side
B-p=pw+p-p
B-p=pw
Divide each side by p
(B-p) /p = pw/p
(B-p) /p = w
B/p -1 =w
What is the pattern in the values as the exponents increase?
Answer:
"Multiply the previous value by 2"
Step-by-step explanation:
Let's check the first 2 terms for all the answer choices.
1. Add [tex]\frac{1}{16}[/tex] to the previous value:
[tex]\frac{1}{32}+\frac{1}{16}=\frac{3}{32}[/tex]
Doesn't match.
2. Subtract [tex]\frac{1}{16}[/tex] from the previous value:
[tex]\frac{1}{32}-\frac{1}{16}=-\frac{1}{32}[/tex]
Doesn't match.
3. Divide the previous value by 2:
[tex]\frac{\frac{1}{32}}{2}\\=\frac{1}{32}*\frac{1}{2}=\frac{1}{64}[/tex]
Doesn't match.
4. Multiply the previous value by 2:
[tex]\frac{1}{32}*2=\frac{2}{32}=\frac{1}{16}[/tex]
DOES WORK!
Also, doing the same thing with all the other values would give us matching answer. So this choice is right.
a point occupies zero dimensions true or false
Answer: True.
Step-by-step explanation:
In geometry , we have three undefined terms as :
1) point [ no dimension]
2) line [ one dimension]
3) plane [ two dimension]
A point is just a tiny mark on Cartesian plane which has no length like a line , no width and area like a plane or no volume like a three dimensional shape . We can use only its location but cannot measure it.
Hence, it has no dimension.
Hence, the given statement "a point occupies zero dimensions" is a true statement.
Answer:true

Tell whether the given ordered pair is a solution of the equation 4y + 2x = 3; (1.5,0)
Answer:
Yes, it is a solution
Step-by-step explanation:
Plug the given (x, y) point of (1.5, 0) into the equation to find out...
4(0) + 2(1.5) = 3
0 + 3 = 3
3 = 3
The given ordered pair (1.5,0) is a solution of the equation 4y + 2x = 3.
What does the solution of an equation mean?The solution of an equation, when substituted makes the left-hand side equal to the right-hand side. It is the value for which the LHS = RHS.
We can determine whether the ordered pair is a solution as shown below:The equation is 4y + 2x = 3.
The given ordered pair is (x,y) = (1.5,0). Now substitute the values of x and y.
4y + 2x = 3
⇒ 4(0) + 2(1.5) = 3
⇒ 0 + 3 = 3
⇒ 3 = 3
Therefore, we have determined that the given ordered pair (1.5,0) is a solution of the equation 4y + 2x = 3.

I DON'T understand
Answer:
f(g(x)) = 72x^2+1
Step-by-step explanation:
f(x) = 2x^2 +1
g(x) = -6x
f°g(x) means f(g(x))
Take g(x) and substitute it in for x in f(x)
f(g(x)) = 2(g(x))^2 +1
=2(-6x)^2 +1
=2(36x^2) +1
=72x^2 +1

3.Find the length of the missing side the triangle is not drawn to scale 37 and 35
The length of the missing side is 12.
The length of the missing side of the triangle can be calculated using pythagoras rule ;
Adjacent² = hypotenus² - opposite²
Substituting our values ;
a² = 37² - 35²
a² = 1369 - 1225
a² = 144
Take the square root of both sides ;
a = √144
a = 12
Hence, the length of the missing side is 12.
Basd on the right-angled triangle, the length of the missing side is equal to 12 units.
In Mathematics and Euclidean Geometry, Pythagorean theorem can be represented by the following mathematical equation (formula):
[tex]z^2=x^2 + y^2[/tex]
Where:
x is the opposite side of a right-angled triangle.
y is the adjacent side of a right-angled triangle.
z is the hypotenuse of a right-angled triangle.
Note: Let the variable "x" represent the missing side length.
In order to determine the missing side length, we would have to apply Pythagorean's theorem as follows;
[tex]37^2=x^{2} +35^2\\\\x^2=37^2-35^2\\\\x^{2} =1369-1225\\\\x^{2} =144\\\\x=\sqrt{144}[/tex]
x = 12 units.

Solve the equation for y. 2x + 5y = 5
Answer:
see explanation
Step-by-step explanation:
given
2x + 5y = 5 ( isolate the term in y by subtracting 2x from both sides )
5y = 5 - 2x ( divide both sides by 5 )
y = [tex]\frac{5-2x}{5}[/tex]
To solve 2x + 5y = 5 for y, subtract 2x from both sides and then divide by 5 to get y = 1 - (2/5)x.
To solve the equation 2x + 5y = 5 for y, we need to isolate y on one side of the equation. Here are the steps to do it:
Subtract 2x from both sides of the equation to get 5y = 5 - 2x.Divide both sides of the equation by 5 to solve for y, which gives us y = (5 - 2x) / 5.Therefore, the solution for y in terms of x is y = 1 - (2/5)x.

The formula for the area of a triangle is a=1/2bh. Hiro is solving the equation for h; his work is shown below. What mistake did Hiro make?
a=1/2bh
2(x)a=2(x)(1/2bh)
2a=bh
2a-b=h
(x) is multiplication sign btw
Hiro should have divided both sides of the equation by 2. Hiro should have divided both sides of the equation by b. Hiro should have added b to both sides of the equation. Hiro should have subtracted 2 from both sides of the equation.
Example
If b = 5 and h = 10
a = 1/2 * b * h
a = 1/2 * 5 * 10
a = 25
2a = 2 (1/2 * b * h)
2 * 25 = 2 (1/2 * 5 * 10)
50 = 2 (25)
50 = 50
2a = b * h
2 * 25 = 5 * 10
50 = 50
2a - b = h
2 * 25 - 5 = 10
50 - 5 = 12
45 = 10
This is false.
If Hiro divided both sides by 2 instead:
2a ÷ 2 = b * h ÷ 2
2 * 25 ÷ 2 = 5 * 10 ÷ 2
50 ÷ 2 = 50 ÷ 2
25 = 25
Answer:
Hiro should divide both sides by 2.

Find the perimeter of a square that is 3 and 3/4 in on a side.
A) 7 1/2 inches
B) 15 inches
C)12 3/4 inches

Perimeter is the sum of all four sides.
A square has 4 equal sides, so all the sides of the square are 3 3/4 inches.
Perimeter = 3 3/4 x 4 = 15 inches.

How much money will you have if you started with $1250 and put it in an account that earned 6.7% every year for 14 years?
Answer:
$3098.93
Step-by-step explanation:
We can use the formula for compound growth to solve this. The formula is:
[tex]F=P(1+r)^t[/tex]
Where
F is the future value (the value at end of 14 years, our answer)
P is the initial amount invested ($1250)
r is the interest rate, in decimal (6.7% is 0.067)
t is the time in years (14, in our case)
Plugging in all the information we have:
[tex]F=P(1+r)^t\\F=1250(1+0.067)^14\\F=1250(1.067)^14\\F=3098.93[/tex]
The account will accrue $3098.93 after 14 years.

Is a centimeter more or less then a meter
Answer:
A meter is 100 times larger than a centimeter
Step-by-step explanation:
A meter is larger than a cm. u can try it on a ruler. look at the cm notice how it is smaller than a meter.
Answer:
It depends.
Step-by-step explanation:
I won't say centimeter is less or more than a meter, because 1 meter is equal to 100 center centimeter. But when you compare different measurement it can, for example:
2 m = 200 cm (Both are same)
3 m > 250 cm (m is greater, actually 3m = 300 cm)
4 m < 450 cm (cm is greater, 4 m = 400 cm)

Write an equation for g(u) in terms of u.
-3u + 6 = 18v - 6
Answer:
-1/6 u + 2/3 = v
Step-by-step explanation:
You can solve for v here so that the equation is in terms of u.
-3u + 6 = 18v - 6 Add 6 to both sides
-3u + 12 = 18v Divide everything by 18
-3/18 u + 12/18 = v Simplify fractions
-1/6 u + 2/3 = v
