Solve the following equation. x^2 + 6x − 40 = 0

Mathematics
1 answer:
jonny [76]3 years ago
8 0

Answer:

x = 4 and -10

Step-by-step explanation:

Given the equation

x²+6x-40= 0

The common factors to use for the factorisation are +10 and -4

x²+(10x-4x)-40=0

(x²+10x)-(4x-40) = 0

x(x+10)-4(x+10) = 0

(x-4)(x+10) = 0

x-4 =0 and x+10 = 0

x = 4 and x = -10

The manufacturer of widgets spends $5 to make each widget and sells them for $8. The manufacturer also has fixed costs each mont
Minchanka [31]

Answer:

400

Step-by-step explanation:

The manufacturer spends $5 to make each widget and sells them for $8.  This means that each widget gives him a profit of $3.

8 - 5 = 3

You need to figure out how many widgets it will take for the manufacturer to make up for the costs each month ($1200).

3x = 1200

(3x)/3 = 1200/3

x = 400

The manufacturer needs to sell 400 widgets.

The histogram shows the number of miles driven by a sample of automobiles in New York City. What is the maximum possible number
hjlf

Answer:

The maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.

Step-by-step explanation:

A histogram is a bar graph reprinting the frequency of various categories.

In a histogram the <em>y</em>-axis represents the frequency and the <em>x</em>-axis represents the categories.

Consider the histogram provided for the number of miles driven by a sample of automobiles in New York City.

The <em>y</em>-axis represents the frequency and the <em>x</em>-axis represents the number of miles driven.

The category 10,000 miles has the highest frequency at 30.

And the maximum possible number of miles traveled by an automobile is 40,000 miles.

Thus, the maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.
