Answer:
8 pigs
Step-by-step explanation:
Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.
Suppose all animals are chickens.
Total no. of feet = 26 chickens × 2 feet
= 52 feet
Difference in total no. of feet = 68 feet - 52 feet
= 16 feet
Difference in no. of feet each animal has
= 4 feet (a pig) - 2 feet (a chicken)
= 2 feet
∴ No. of pigs = 16 feet ÷ 2 feet
= 8 pigs
Answer:
√185 units.
Step-by-step explanation:
To find the distance between two points, A (-2, -3) and B (6, 8), you can use the distance formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
In this formula:
(x₁, y₁) represents the coordinates of point A (-2, -3).
(x₂, y₂) represents the coordinates of point B (6, 8).
Now, plug the values into the formula:
Distance = √[(6 - (-2))² + (8 - (-3))²]
Distance = √[(6 + 2)² + (8 + 3)²]
Distance = √[(8)² + (11)²]
Distance = √[64 + 121]
Distance = √185
So, the distance between points A (-2, -3) and B (6, 8) is √185 units.

A function having a range of all real numbers is a function where any output value can be achieved. An example is y=sinx, which oscillates continuously between -1 and 1, thus covering all real numbers in its range.
The function which has a range of all real numbers is a function where any output (y-value) is possible, irrespective of the input. The range of a function is the complete set of possible output values (y-coordinates), which result from using the function formula. An example of a function with a range of all real numbers is y=sinx. Since y=sinx oscillates between -1 and 1, given a large number of repetitions (or a continuous plot from -infinity to +infinity), all real numbers in your range (-1 to 1) are represented.

Therefore, the value of x is -4 if A= B and AB= 3x-5 BC= 5x-6 and AC = 2x-9.
An equation is a mathematical statement that shows the equality of two expressions. It is composed of two sides, separated by an equals sign (=), indicating that the two sides are equivalent in value. An equation may contain variables, which are unknown values represented by letters, as well as constants, which are known values. Equations are used in many areas of mathematics and science to model and solve problems. For example, the equation y = mx + b is a linear equation that describes the relationship between the variables x and y in a straight line, where m is the slope of the line and b is the y-intercept. Equations can be solved by manipulating the variables and using mathematical operations to isolate the unknown value.
Here,
Since A = B, we know that AB = B². So, we can rewrite the equation AB = 3x - 5 as B² = 3x - 5.
Similarly, we can rewrite BC = 5x - 6 as B² = 5x - 6, and AC = 2x - 9 as A² - B² = (2x - 9) - (B^2).
Since we know that A = B, we can substitute B for A in the last equation to get:
B² - B² = (2x - 9) - (B²)
Simplifying this equation, we get:
0 = 2x - 9 - B²
Now we can substitute the equation B² = 3x - 5 into the above equation to get:
0 = 2x - 9 - (3x - 5)
Simplifying this equation, we get:
0 = -x - 4
Solving for x, we get:
x = -4
