Answer:

B. m = 5/4

Step-by-step explanation:

Slope m = (y2 - y1)/(x2 - x1)

m = (-10 - -5)/(1 - 5) = -5/-4 = 5/4

The graph of g(x) is shifted 4 units up from the parent function

The equation of the parent function f(x) is given as

f(x) = x

The transformed function is given as

g(x) = x + 4

Substitute the known values in the above equation, so, we have the following representation

g(x) = f(x) + 4 or g(x) = f(x + 4)

This means that the function is shifted to the left by 4 units or it is shifted up by 4 units

The fruit bat in centimeters is 17.78 centimeters

The theory used in this question is the conversion of units. Conversion of units is the process of changing the magnitude of a physical quantity from one unit to another.

For example, converting between meters and feet or liters and gallons. The most common type of conversion is between the metric and imperial systems of measurement.

Step 1: Convert the length in inches to centimeters.

          7 inches = 2.54 centimeters

Step 2: Multiply the length in inches (7 inches) by 2.54.

       2.54*7 = 17.78 centimeters

Step 3: The result is 17.78 centimeters.

Answer:

2(x² + 5)

Step-by-step explanation:

To factor 2x² + 10, we can first factor out the greatest common factor of the terms, which is 2:

2x² + 10 = 2(x² + 5)

We can't factor anymore, so the answer is:

2(x² + 5)

Answer:

2(x² + 5)

Step-by-step explanation:

To factorise this, do the distributive property backwards. In other words:

2x² + 10

2x² ÷ 2 + 10 ÷ 2

x² + 5

2(x² + 5)

∴ 2(x² + 5) is the answer

For the given exponential function f(x) = abˣ, the value of a and b is given as 7 and 5 respectively.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given function,
f(x) = abˣ

Put x = 2 and f(x) = 175,
175 = ab² - - - - (1)

Put x = 0 and f(x) = 7,
7 = ab⁰
Since b° = 1
a = 7

Put a = 7 in equation 1,
175 = 7b²
b² = 175 / 7
b² = 35
b = 5

Thus, the required simplified value of the a and b is 7 and 5 respectively.

Answer:

where is the numer line?

Step-by-step explanation:

Aircraft A has 312 seats.

Let's assume that Aircraft B has x seats.

According to the given information, Aircraft A has 105 more seats than Aircraft B. So, the number of seats in Aircraft A can be expressed as x + 105.

The total number of seats in both aircraft is 519, which can be represented by the equation:

x + (x + 105) = 519

Simplifying this equation, we have:

2x + 105 = 519

Subtracting 105 from both sides, we get:

2x = 414

Dividing both sides by 2, we find:

x = 207

Therefore, Aircraft B has 207 seats.

To find the number of seats in Aircraft A, we substitute the value of x back into the expression x + 105:

Aircraft A = 207 + 105 = 312

Hence, Aircraft A has 312 seats.

The polynomial -8m²n - 7m²n can be factored using the common factor -m²n. The complete factored form of the polynomial is (-m²n) (8 + 7a).

To find the complete factored form of the polynomial -8m²n - 7m²n, we can factor out common terms from both the terms. The common factor in the terms -8m²n and -7m²n is -m²n. We can write the polynomial as:

-8m²n - 7m²n = (-m²n) (8 + 7a)

Therefore, the complete factored form of the polynomial -8m²n - 7m²n is (-m²n) (8 + 7a). This expression represents the original polynomial in a multiplied form. We can expand this expression using distributive law to verify that it is equivalent to the original polynomial.

Applying the negative exponent, it is found that the equivalent expression to \(3^{-3}\) is \(\frac{1}{27}\).

When we have a negative exponent, we use a fraction, with the term with the exponent going to the denominator, as follows:

\(a^{-b} = \frac{1}{a^b}\)

Hence, in this problem, the equivalent expression is:

\(3^{-3} = \frac{1}{3^3} = \frac{1}{27}\)

The statement is False.

If the equation of the regression line that relates hours per week spent in the lab, x, to GPA, y, is

y = 2.1 + 0.28x

If a student never goes to the lab (x=0), then the best prediction for their GPA would be y = 2.1 + 0.28*0 = 2.1.

A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It may be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.

The relationship between dispersed data points in any collection is shown by a regression line. When there is a linear pattern, it displays the relationship between the dependent y variable and independent x variables.
