Answer:
Slope = -7/2
Step-by-step explanation:
The standard equation of a line is expressed as y = mx+c
m is the slope
c is the y-intercept
Given the equation y = -7/2 x - 5/8
Compare with the general equation
mx = -7/2x
Divide both sides by x
mx/x = -7x/2x
m = -7/2
Hence the slope of the line is -7/2

Fill in the blank to make the two fractions equivalent. 5/8 = x/24
Answer:
1) The trick to making these fractions equivalent is to make sure they have the same denominator. to do this you need to know your multiplication facts. These are the multiples when you multiply two numbers together.
2) Since 24 is the largest denominator, you need the smallest denominator into 24ths, which you do by multiplying 8 x 3, giving you 24.
3) Whatever you do to the denominator, you do to the numerator, so multiply 5 x 3, which is 15.
4) New fraction for 5/8 becomes 15/24.
5) So 5/8 is equivalent. to 15/24.
Step-by-step explanation:
5/8 = x/24
5 x 3 = 15
8 x 3 24
Proof: Reduce 15/24 by dividing 3 into both numbers (15÷3) and (24÷3) = 5/8.

What is logarithm and what are the properties of logarithm?
Logarithm is a mathematical operation that is the inverse of exponentiation. It is denoted by log b (x), which means the logarithm of x to base b.
For example, log2 8 = 3, since 23 = 8. Logarithm is useful in solving equations that involve exponential terms.
The properties of logarithm are:
1. log b 1 = 0: This property states that the logarithm of 1 is zero for any base b.
2. log b b = 1: This property states that the logarithm of any base b is 1.
3. log b (xy) = log b (x) + log b (y): This property states that the logarithm of the product of two numbers is equal to the sum of the logarithms of the two numbers. For example, log2 (8x32) = log2 8 + log2 32 = 3 + 5 = 8.
4. log b (x/y) = log b (x) - log b (y): This property states that the logarithm of the quotient of two numbers is equal to the difference of the logarithms of the two numbers. For example, log2 (8/32) = log2 8 - log2 32 = 3 - 5 = -2.
5. log b c = clog b (c): This property states that the logarithm of a number c to the base b is equal to c times the logarithm of b. For example, log2 32 = 32log2 2 = 5.
These properties of logarithm are very useful in solving mathematical problems involving exponential terms.

Nine years ago, Katie was twice as old as Elena was then. Elena realizes, "In four years, I'll be as old as Katie is now!" Elena writes these equations to help make sense of the situation: k - 9 = 2(e - 9)
e + 4 = k
If Elena is currently e years old and Katie is k years old, how old is Katie now?
Answer: Katie is 9 years old now. ✅
Step-by-step explanation:
By using the second equation, we can find that k = e+4,
then we can substitute k = e+4 into the first equation
k-9 = 2(e-9)
e+4-9 = 2(e-9)
e-5 = 2e-18
5 = e
so k = e + 4 = 5 + 4 = 9

How do you find the absolute value of a complex number in polar form?
The absolute value of the complex number z = 2∠45° is therefore equal to 2.
What is value?Value can be defined as the worth of something, which may be monetary, social, or personal. It is an intangible concept that is based on individual beliefs and opinions. Value can be determined by considering the utility, quality, scarcity, desirability, and other factors associated with an item. Values can be measured in terms of tangible goods, such as money, or in terms of intangible goods, such as love or honor.
The absolute value of a complex number in polar form is the magnitude of the complex number. It is also referred to as the modulus of the complex number. To find the absolute value of a complex number in polar form, we need to use the following equation:
Absolute Value = r = |z| = √(a² + b²)
Where 'r' is the absolute value of the complex number, 'z' is the complex number, and 'a' and 'b' are the real and imaginary parts of the complex number respectively.
For example, if we have a complex number in polar form, such as z = 2∠45°, then the absolute value of the complex number is calculated by taking the square root of the sum of the squares of the real and imaginary parts:
Absolute Value = r = |2∠45°| = √(2² + 0²) = 2
The absolute value of the complex number z = 2∠45° is therefore equal to 2.

Solve 3x 1 = 15 for x using the change of base formula log base b of y equals log y over log b. −0.594316 1.405684 1.464973 3.469743
Using the change of base formula log base b of y equals log y over log b x = 4.69743.
To solve 3x + 1 = 15 for x, we can use the change of base formula, which states that log base b of y equals log y over log b. In this case, we can use log base 3 on both sides of the equation to solve for x.
First, we take the log base 3 of both sides of the equation:
log base 3 (15) = log base 3 (3x + 1)
Next, we can use the property of logarithms, which states that log base b (xy) = log base b (x) + log base b (y):
log base 3 (15) = log base 3 (3) + log base 3 (x + 1/3)
We can solve for x by subtracting log base 3 (3) from both sides of the equation:
log base 3 (15) - log base 3 (3) = log base 3 (x + 1/3)
We can then use the change of base formula to solve for x:
log 15/3 = log x + 1/3 over log 3
We can then solve for x by taking the antilog of both sides of the equation:
15/3 = x + 1/3
We can then solve for x by subtracting 1/3 from both sides of the equation:
15/3 - 1/3 = x
Finally, we can solve for x by dividing both sides of the equation by 3:
x = (15/3 - 1/3) / 3
Therefore, x = 4.69743.

What is inequality?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.
Firm the question, the amount she spends on food every month is 16x and the amount he spends on travel every month is 5y.
Therefore, the total amount she spends every month is 16x+5y.
