for the function y=1/2-x at what values of x will the rate of change of y with respect to x equal 1/16

The given expression is

Notice that the hundredth 7 is greater than 5, this means 19.67 is greater than 19.657.

If the ratio of trucks to trucks is 5 to 8,

then we can use proportions to solve for the number of truck (unknown "x"):

5 / 8 = x / 440

we solve for x by multiplying: by 440 both sides

x = 440 * 5 / 8

x = 275

There are 275 trucks on the freeway.

Let the horizontal distance be represented with x

We can deduce from the information that MAT 012 has 3 sections, namely:

Our section, and two other sections

Then, we can also infer that MAT012 has a total of:

Our task will be to get the percentage of our section taking MAT 102

Since our section has 23

Then we can calculate the answer as

Thus, the answer is 34.33%

Here we must apply the following rule:

Since m ∠NRQ = 42°, we have:

You have the following inequality:

z/4 ≤ 12

To solve the previous inequality you proceed as follow:

z/4 ≤ 12 multiply both sides by 4

z ≤ 48

Hence, the solution is z ≤ 48

when you want to graph a solution of the form "z lower or equal than", you draw a black point, that means the solution are all number lower than 48, including 48.

We are asked to factor in the following expression:

To do that we will multiply by 3/3:

Now, we use the distributive property on the numerator:

Now we factor in the numerator on the right side in the following form:

Now, in the spaces, we need to find 2 numbers whose product is 12 and their algebraic sum is 7. Those numbers are 4 and 3, since:

Substituting the numbers we get:

Now we take 3 as a common factor on the parenthesis on the right:

Now we cancel out the 3:

Therefore, the factored form of the expression is (3y + 4)(y + 1).

If l and m are parallel, then ∠1 must measure 55°.

The addition of the angles of a triangle is equal to 180°, in consequence,

We have the tickets sold each weekend:

• Last weekend: 26,675

• This weekend: 24,567

We have to find how many tickets where sold in both weekends by rounding each number to the nearest thousand units. This will let us do the math without a calculator.

Then, we can approximate 26,675 to 27,000 and 24,567 to 25,000.

NOTE: we round the numbers up because the next number is 5 or greater. Then 675 is and 567 are approximated as 1,000.

We then can add them as: 27,000+25,000 = 52,000.

Answer: the solution is about 52,000 tickets sold.

NOTE: the exact solution would have been 51,242

Answer:

y=14000x

Step-by-step explanation:

x represents years after 2020 and y is the number of miles

The required equation for the distance travelled versus number of years after 2020 is given as y = 14000x + 56000.

To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.

The given problem can be solved as follows,

Suppose the year 2020 represents x = 0.

The distance travelled per year can be taken as the slope of the linear  equation.

This implies that slope = 14000.

And, the distance travelled by January 1, 2020 is 56000.

It implies that for x = 0, y = 56000.

The slope-point form of a linear equation is given as y = mx + c.

Substitute the corresponding values in the above equation to obtain,

y = 14000x + c

At x = 0, y = 56000

=> 56000 = 14000 × 0 + c

=> c = 56000

Now, the equation can be written as,

y = 14000x + 56000

Hence, the required equation for number of miles and years for the car is given as y = 14000x + 56000.

Answer: 6x + 8 = 32

Explanation:

Let x represent the number

6 times the number = 6 * x = 6x

If we add 6x to 8, it becomes

6x + 8

Given that the result is 32, the equation could be used to solve the problem is

6x + 8 = 32

An example of a problem for the given diagram:

You go to a store to buy the school supplies you will need for the next term. There are boxes of 7 pencils each, and you decide to buy 5 of those boxes. How many pencils do you end up buying?

When broken open Austen's jawbreaker will make a hemisphere.

Recall that the total surface area of a hemisphere is given by

Where r is the radius of the hemisphere.

We are given the diameter of the hemisphere that is 16.4 inches.

The radius is half of the diameter.

So, the radius is 8.2 inches

Substitute the radius into the above formula of total surface area

Therefore, the total surface area of the hemisphere is 633.72 square inches.

Please note that if you want to find out only the curved surface area then use the following formula

For the given case, the curved surface area is 453.96 square inches.

Here we are given a geometrical shape with the following inner and an arc angle as follows:

Property: The inner angle is always the mean of corresponding verticaly opposite arc angles.

We can express the above property in lieu to the geometry question at hand. We see that the two arc angles:

Ther inner vertically opposite angle are:

The property can be expressed mathematically as follows:

Next plug in the respective values of angles and evaluate for the arc angle BG as follows:

Therefore the correct option is:

L = length

W = width

L = 4 + 3*W

The perimeter of a rectangle is the sum of its sides: 2L + 2W. Since it's 72, we have:

2L + 2W = 72

Now, to solve for L and W, the dimensions of the garden, we can use the first equation (L = 4 + 3*W) into the second one (2L + 2W = 72):

2L + 2W = 72

2 * (4 + 3*W) + 2W = 72

2 * 4 + 2 * 3W + 2W = 72

8 + 6W + 2W = 72

8W = 72 - 8

8W = 64

W = 64/8 = 8

Then we can use this result to find L:

L = 4 + 3W = 4 + 3 * 8 = 4 + 24 = 28

Therefore, the garden has a width of 8 and a length of 28.

We know that

• The mean is 200 pounds.

• The standard deviation is 25 pounds.

• The random sample is 35.

First, let's find the Z value using the following formula

Let's replace the mean, the standard deviation, and x = 210.

Then, using a p-value table associated with z-scores, we find the probability

The table used is shown below

We have a function of which we only know the graph.

We have to find in which intervals the function is decreasing.

We know that a function is decreasing in some interval when, for any xb > xa in the interval, we have f(xa) < f(xb).

This means that when x increases, f(x) decreases.

We can see this intervals in the graph as:

We assume each division represents one unit of x. Between divisions, we can only approximate the values.

Then, we identify all the segments in the graph where f(x) has a negative slope, meaning it is decreasing.

We have the segments: [-3, -1.5), (1,5, 4.5) and (7,9].

Answer:

The right options are:

Between 1.5 and 4.5

Between -3 and -1.5

Between 7 and 9

we have the expression

3/4 - 1/2 × 7/8

Remember that

3/4 is equivalent to 12/16 (multiply by 4 both numerator and denominator)

therefore

Given the following question:

y = 116

x = 64

In order to determine the limit of f(x) when x tends to -4 from the right (4^+), we need to look in the table the value that f(x) is approaching when x goes from -3.9 to -3.99 to -3.999.

From the table we can see that this value is 0.4.

Then, to determine the limit of f(x) when x tends to -4 from the left (4^-), we need to look in the table the value that f(x) is approaching when x goes from -4.1 to -4.01 to -4.001.

From the table we can see that this value is 1.5.

Since the limit from the left is different from the limit from the right, the limit when x tends to -4 is undefined.

Finally, the value of f(-4) is the value of f(x) when x = -4. From the table, we can see that this value is -4.
