Answer:

7(-6) + 4(8) = -42 + 32 = -10, so (-6, 8) is the solution to this system of equations.

The answer is Yes.

5/2 pounds is equal to 40 ounces.

We have to find the 5/2 pounds to ounces

1 pound is equal to 16 ounces.

To convert 5/2 pounds to ounces, we can multiply by 16:

5/2 pounds × 16 ounces/pound = 40 ounces

Therefore, 5/2 pounds is equal to 40 ounces.

The equation of the line having slope 0 and passing through (-3,-2) is f(x) = -2.

Any horizontal line has the same y-value for every point on the line. We are given that the line passes through the point (-3,-2). This means that f(-3) = -2, since the y-value of the point (-3,-2) corresponds to the value of the function at x = -3.

This is because no matter what x-value we plug into the function, the output (y-value) will always be -2. Therefore, the equation of the line in function notation is f(x) = -2.

The margin of error for this survey, expressed as a proportion to the nearest thousandth, is 0.021.

To calculate the margin of error for a survey, we need to use the formula:

Margin of Error = Critical Value * Standard Error

1. The critical value is determined based on the desired level of confidence. Since we want a 95% confidence level, we need to find the critical value associated with a 95% confidence interval.

2. For a 95% confidence interval, the critical value is approximately 1.96. This value corresponds to a standard normal distribution.

3. The standard error represents the standard deviation of the sample proportion. It can be calculated using the formula:

Standard Error = sqrt[(p * (1 - p)) / n]

where p is the sample proportion (proportion of respondents who preferred Candidate A) and n is the sample size.

4. In this case, the sample proportion is 350/1750 = 0.2 (or 20% in percentage terms). The sample size is given as 1750.

5. Plugging the values into the formula, we get:

Standard Error = sqrt[(0.2 * (1 - 0.2)) / 1750] = sqrt(0.00022857) ≈ 0.015.

6. Finally, we can calculate the margin of error:

Margin of Error = 1.96 * 0.015 ≈ 0.029.

Rounding the margin of error to the nearest thousandth, we get 0.029, which is equivalent to 0.021 when expressed as a proportion without the ± symbol.

Did you ever get the answer

The value of angle A and C is 14° and 121° respectively

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

The sum of angle in a triangle is 180°

Therefore 45+6x-5+x-7 = 180

collect like terms

45-5-7+6x+x =180

33+7x = 180

7x = 180 - 33

7x = 147

x = 147/7

x= 21

therefore the value of angle A = ( 21-7) = 14°

and angle C = 6(21) - 5

In order to solve this problem, we must set up a proportion. Proportions are an equation that states that two ratios are equal. In this case, we are looking for the number of cats (c) in the animal shelter.

Let's set up the proportion.

5/3 = 25/c

We can then solve for c by multiplying both sides by c.

Answer:

Step-by-step explanation:

let x be the heigth we are looking for.

Each rectangle that covers the cuboid is the product of two dimensions \((60\cdot40;\ 60x;\ 40x)\)

Since it's a cuboid, we assume opposite sides are equal.

So each rectangle is counted twice:

\(Area=2(60\cdot40+60x+40x)=14800\)

Now, we just isolate x:

A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend.

A test score, for instance, may be a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were. Typically, when attempting to establish a connection between two variables, the goal is to determine what causes the dependant variable to vary in the manner that it does.

Many people struggle to recall which variable is the independent variable and which variable is the dependent variable.

Answer:

The age of the mother is 42 years, while the age of the girl is 7 years.

Step-by-step explanation:

Given that 1/6 of the age of a mother is the age of her daughter, to determine the age of the mother if the difference of their age is 35, the following calculations must be performed:

6 - 1/6 = 5/6

5/6 = 35

35/5 = 7

7 + 35 = 42 = 7 x 6

7 = 7 x 1

Therefore, the age of the mother is 42 years, while the age of the girl is 7 years.

Barbara's Produce Stand has the best buy on tomatoes

Step-by-step explanation:

Average Value

We need to determine which produce stand has the best buy on tomatoes. We'll calculate the average cost of each tomato in both stands and select the one that has the lowest cost.

Al's Produce Stand sells 6 tomatoes for $0.90, The average cost per tomato is $0.90/6=$0.15

Barbara's Produce Stand sells 11 tomatoes for $1.54. The average cost per tomato is $1.54/11=$0.14

Since the latter's cost is less than the first one, Barbara's Produce Stand has the best buy on tomatoes

Answer:

x = 7/3

Step-by-step explanation:

Given equation:

To determine the value of "x", we need to isolate the x-variable and it's coefficient on one side of the equation. This can be done by subtracting 49 to both sides of the equation.

We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.

Clearly, we can see that 9x² and 49 are perfect squares. Therefore,

Take square root both sides of the equation:

To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation

Therefore, the value of "x" must be 7/3.

Answer:

x = 7∕3, –7∕3

Step-by-step explanation:

To find the solutions of the quadratic equation -9x^2 + 49 = 0, we can solve for x by isolating x^2 first:

-9x^2 + 49 = 0

-9x^2 = -49

Dividing both sides by -9, we get:

x^2 = 49/9

Taking the square root of both sides, we get:

x = ± 7/3

Therefore, the solutions of the quadratic equation -9x^2 + 49 = 0 are x = 7/3 and x = -7/3.

Answer:

The inverse is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x) = (x+3)^5

Finding the inverse,

\(f(x) = (x+3)^5\\or,\\y = (x+3)^5\)

We replace x with y and vice versa

so,

\(x = (y+3)^5\)

Solving for y,

the the 5th root,

\(\sqrt[5]{x} = y + 3\\y = \sqrt[5]{x} - 3\)

hence the inverse function is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x)=(x+3)×5

Y=5X+15

now

interxchanging x and y we get,

x=5y+15

5y=x-15

y=x-15/5

therefor f~1(x)=x-15/5
