Explanation:
Inequalities are solved just like regular equations. The difference is that you need to take care to reverse the direction when multiplying or dividing negative numbers.
The simplest way to solve an inequality is to first solve it as an equality, and then CHECK the value to find out which way the sign should point.

Step-by-step explanation:
Since it is stated 2 times 5 to the power of 4, then we would write it out as:
2 x 5 x 5 x 5 x 5
Step-by-step explanation:
2(5)^4- Since we go by PEMDAS (please excuse my dear aunt sally, or parenthesis, exponent, multiplication, division, addition, and subtraction) and there are no parenthesis, we see there is an exponent in this equation
To solve for an exponent multiply a number however many times the exponent tells you to... In this case 5^4 would be the same as:
5 x 5 x 5 x 5, which is equal to 625.
- From there, multiply 625 x 2 to get 1250 because Multiplication comes next in Order of Operations/PEMDAS

Answer:
x = 12
Step-by-step explanation:
For q and r to be parallel, then
11x - 28 and 7x - 8 are same-side interior angles and sum to 180° , so
11x - 28 + 7x - 8 = 180 , simplify left side
18x - 36 = 180 ( add 36 to both sides )
18x = 216 ( divide both sides by 18 )
x = 12

A. The relationship is linear; y + 7 = 1/2(x – 5).
B. The relationship is linear; y – 5 = -1/2(x + 7).
C. The relationship is linear; y – 5 = 2(x + 7).
D. The relationship is not linear.
Answers
Answer:
C. The relationship is linear; y – 5 = 2(x + 7).
Step-by-step explanation:
The correct answer is:
The relationship is linear, and the equation is
y-5 = 2(x+7).
Explanation:
To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:
The slope between the first two points is given by:
The slope between the second pair of points is given by:
The slope between the third pair of points is given by:
Since the slope is the same throughout the data, the relationship is linear and the slope is 2.
To write the equation, we use point-slope form, which is:
y-y₁ = m(x-x₁)
Using the first point, we have:
y-5 = 2(x--7)
y-5 = 2(x+7)
The answer is The relationship is linear; y - 5 = 2(x + 7).
What is the greatest common factor of 64xyz−36xy+24x?
Answers
1) Find the Greatest Common Factor (GCF).
4x
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
[tex]4x(\frac{64xyz}{4x} +\frac{-36xy}{4x} +\frac{24x}{4x})[/tex]
3) Simplify each term in parentheses.
[tex]4x(16yz-9y+6)[/tex]
The greatest common factor of equation A = 64xyz - 36xy + 24x is 4x
A = 4x ( 16yz - 9y + 6 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
A = 64xyz - 36xy + 24x
Now , the Greatest Common Divisor is the highest number that divides exactly into two or more numbers. It is also expressed as GCF
So , the equation A can be factorized as
Taking 4x as the common term of the equation , we get
A = 4x ( 16yz - 9y + 6 )
So , the common term is 4x and the greatest common factor of the equation A is 4x
Therefore , the GCF is 4x
Hence , The greatest common factor of equation A = 64xyz - 36xy + 24x is 4x and A = 4x ( 16yz - 9y + 6 )
