Answer:
-7
Step-by-step explanation:
1. Get rid of the brackets: 12-3r +23+8r
2. move the like terms to one side of the equation: -3r+8r = -23-12
3. Simplify: 5r = -35
4. divide both sides by 5: r= -7
2(x-3)+9=3(x+1) +x what is x
Answer: 3
Step-by-step explanation: Simplifying
2(x + -3) + 9 = 3(x + -1) + x
Reorder the terms:
2(-3 + x) + 9 = 3(x + -1) + x
(-3 * 2 + x * 2) + 9 = 3(x + -1) + x
(-6 + 2x) + 9 = 3(x + -1) + x
Reorder the terms:
-6 + 9 + 2x = 3(x + -1) + x
Combine like terms: -6 + 9 = 3
3 + 2x = 3(x + -1) + x
Reorder the terms:
3 + 2x = 3(-1 + x) + x
3 + 2x = (-1 * 3 + x * 3) + x
3 + 2x = (-3 + 3x) + x
Combine like terms: 3x + x = 4x
3 + 2x = -3 + 4x
Solving
3 + 2x = -3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
3 + 2x + -4x = -3 + 4x + -4x
Combine like terms: 2x + -4x = -2x
3 + -2x = -3 + 4x + -4x
Combine like terms: 4x + -4x = 0
3 + -2x = -3 + 0
3 + -2x = -3
Add '-3' to each side of the equation.
3 + -3 + -2x = -3 + -3
Combine like terms: 3 + -3 = 0
0 + -2x = -3 + -3
-2x = -3 + -3
Combine like terms: -3 + -3 = -6
-2x = -6
Divide each side by '-2'.
x = 3
Simplifying
x = 3

The interval notation for the given exponential inequality is (-3/2, ∞).
The exponential inequality is [tex](\frac{1}{2} )^{2x}+1 < 4[/tex].
What is an exponential inequality?Exponential inequalities are inequalities in which one (or both) sides involve a variable exponent. They are useful in situations involving repeated multiplication, especially when being compared to a constant value, such as in the case of interest.
Now, the given exponential inequality can be solved as follows:
[tex](\frac{1}{2} )^{2x}+1 < 4[/tex]
⇒ [tex](\frac{1}{2} )^{2x} < 3[/tex]
⇒ [tex]\frac{1}{2^{2x} } < 3[/tex]
Multiply [tex]2^{2x}[/tex] on both the sides of the inequality.
That is [tex]\frac{1}{2^{2x} } .2^{2x} } < 3.2^{2x} }[/tex]
⇒ [tex]1 < 3.2^{2x} }[/tex]
Solve for x
[tex]x=\frac{ln \frac{1}{3} }{2 ln 2}[/tex]
The solution consists of all of the true intervals.
[tex]x > \frac{ln \frac{1}{3} }{2 ln 2}[/tex]
Interval Notation: (-3/2, ∞)
Therefore, the interval notation for the given exponential inequality is (-3/2, ∞).

What is the expression in radical form?
(3p^3q)3/4
Answer:
A
Step-by-step explanation:
Recall that if we are given fractional exponents, we can use the following property:
[tex]\displaystyle x^{ {}^{a}\!/\! {}_{b}} = \sqrt[b]{x^a}[/tex]
We are given the expression:
[tex]\displaystyle (3p^3q)^{ {}^{3}\!/\! {}_{4} }[/tex]
Use the above property, this yields:
[tex]=\sqrt[4]{(3p^3q)^3}[/tex]
Using the power of a power property, we can simplify this to:
[tex]=\sqrt[4]{(3^3)(p^3)^3(q)^3}[/tex]
Simplify:
[tex]=\sqrt[4]{27p^9q^3}[/tex]
In conclusion, our answer is A.
Do 1. Lucas makes the statement: "The exterior angles of a triangle are always
obtuse." of the following, which provides a counterexample to the statement?
о
Right Triangle
&
Acute Triangle
Equilateral Triangle
о o
Isosceles Triangle
CLEAR ALL
The exterior angle to the 90 degree interior angle is 90 degrees because 90+90 = 180. So this exterior angle is not obtuse.
The equilateral triangle always has an obtuse angle and for the isosceles triangle, it may be obtuse or acute.
What is an exterior angle?The angle is formed by a polygonal side and its extended neighboring side. When a transversal cuts one of two lines, it creates an angle that is outside of the line.
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C.
Equilateral triangle always has an obtuse angle and for the isosceles triangle, it may be obtuse or acute.

Answer:
[tex]\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}[/tex]
Step-by-step explanation:
From the picture attached,
Multiplication of two fractions gives the result as [tex]\frac{1}{10}[/tex].
This shows that the denominator of the fractions when multiplied with each other results a number that will be the multiple of 10.
Therefore, from the given numbers,
5 × 6 = 30
Rest two numbers be placed as the numerator of the fractions.
[tex]\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}[/tex]
[tex]=\frac{1}{10}[/tex]
Therefore, [tex]\frac{1}{5}\times \frac{3}{6}=\frac{1}{10}[/tex] will be the answer.
