Clyde and Mason are 432 mi apart from each other in distance.

We are given that:

Clyde and mason can each leave a rest area on the Florida turnpike.

Clyde travels north whereas Mason travels south.

After 4 hr., we get that Clyde has gone 248 mi and Mason, due to the heavy traffic he got , traveled only 184 mi.

We need to tell how far are they from each other.

We will do this by addition.

Distance = 248 mi + 184 mi

Distance = 432 mi.

Therefore, we get that, Clyde and Mason are 432 mi apart from each other in distance.

Mother spent (4r - 8) dollars more on cherries than did the father.

An expression using numbers and related operations is called a numerical expression.

According to the question, a pound of cherries costs $4.

Mom purchased r pounds.

The price of the cherry is calculated as follows: 4r = weight x $/lb.

Father purchased 2 pounds, thus the price of the cherries is 4 (2), or $8.

We remove the smaller value from the higher value, which is 4r - 8, where r must be more than two. Given that the mother spent more money on cherries than the father, the mother's cost of cherries is a greater value.

Answer:

  21

Step-by-step explanation:

You want the value of the expression 2f(-3)-f(4), given that f(x) = 3x²-x+ 5.

A function is evaluated by putting the argument where the variable is, and simplifying the result. Polynomials are often easier to evaluate if they are written in Horner form.

  f(x) = 3x² -x +5

  f(x) = (3x -1)x +5

The values we need are ...

  f(-3) = (3(-3) -1)(-3) +5 = (-10)(-3) +5 = 35

  f(4) = (3(4) -1)(4) +5 = (11)(4) +5 = 49

Then the expression of interest has the value ...

  2f(-3) -f(4) = 2(35) -49 = 70 -49

  2f(-3) -f(4) = 21

The numerical value in this sentence, "the average price of a house in the new subdivision is $257,000" describes a Population Parameter.

A population parameter is a figure that describes a fact about a whole population. In this sentence, we can see that the figure quoted is representative of an entire population. A sample statistic, on the other hand, describes something about a part of a population.

So, for the statement above, we can see that the average price is representative of all the houses in the new subdivision. Thus, the figure is a population parameter.

The gas mileeage in miles per gallon is 44.69 miles per gallon

We'll begin by converting 19 Km/L to miles per litres. This can be obtained as follow:

1 Km/L = 0.621371 mile per litre

Therefore,

19 Km/L = (19 Km/L × 0.621371 mile per litre) / 1 Km/L

19 Km/L = 11.806 miles per lire

We can convert 11.806 miles per litre to miles per gallon as follow:

1 mile per litre = 3.78541178 miles per gallon

Therefore,

11.806 miles per litre = (11.806 miles per litre × 3.78541178 miles per gallon) / 1 mile per litre

11.806 miles per litre = 44.69 miles per gallon

According  to the given data the slope mpq of the secant line pq  for the following values of x are :

The slope is defined as the proportion of both the vertical difference of two points, known as the rise, towards the horizontal change between those same two points, known as the run.

Calculate the values of two line points. Determine the difference in y-coordinates between these two locations (rise). Calculate the x-coordinate distinction between these two locations (run). Divide the x-coordinate variation (rise/run or slope) by the y-coordinate difference.

Slope(m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

You can solve this in a few ways. One way is to graph the equation, and the solution is the x-value of the point of intersection. Another way would be to factor, which is more difficult to complete with a square bigger than 2.

By graphing, you can see a parabola that never touches that x-axis, which means no solution.
