The expression can be simplified as 4x-12/x-3

The expression is

1/(x-3) + 4/(x+5)

= (x+5) + 4(x-3)/(x-3)(x+5)

= 4x-12/x-3

Hence the expression can be simplified as 4x-12/x-3

Step-by-step explanation:

a normal function expresses y (the functional result) in terms of x (and constants).

we need to transform this to express now x in terms of y (and constants).

at the end we only rename x into y and y into x to make it an actual function.

h(x) = y = (-5x + 6)/(3x + 4)

y(3x + 4) = (-5x + 6)

3xy + 4y = -5x + 6

4y - 6 = -5x - 3xy = x(-5 - 3y)

x = (4y - 6)/(-5 - 3y)

and after renaming we get therefore the function

y = h-1(x) = (4x - 6)/(-3x - 5)

Geometric constructions help us to draw lines, angles, and shapes with simple tools.

Given:

A copy of triangle ABC is drawn

He has constructed an angle D and side DE. All he needs to do is constructed another edge.

The process for constructing is to start with point D and create a ray with angle D to point DE.

In order to cross the ray at point F, draw a line parallel to AB.

Answer:

x = 2/3

Step-by-step explanation:

If f(x) = -3x + 4, f(x) = g(x), and g(x) = 2, by the Transitive Property, -3x + 4 = 2

From here we can solve for x.

-3x + 4 = 2
-3x + 4 - 4 = 2 - 4
-3x = -2
3x = 2
3x/3 = 2/3
x = 2/3

Answer:

any number or letter added to zero results in the number itself

Step-by-step explanation:

The average rate of change of h over the interval is -48 feet per second.

Given,

The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by

h(t) = −16t2 + 96t, 0 ≤ t ≤ 6.

We need to find the average rate of change of h over the interval [3, 6].

If we have an interval [a, b] and a function f(x).

The rate of change is given by:

= f(b) - f(a) / b - a

We have,

h(t) = −16t² + 96t and [3, 6].

h(6) = -16 x 6² + 96 x 6 = -576 + 576 = 0

h(3) =  -16 x 3² + 96 x 3 = -144 + 288 = 144

The average rate of change of h is:

= h(6) - h(3) / 6 - 3

= 0 - 144 / 3

= -144 / 3

= -48

Thus the average rate of change of h over the interval is -48 feet per second.

The scale on a blueprint says that 1 cm is the equivalent of 3 ft. A particular line on the blueprint representing a wall measures 12 cm. Wall is 36 ft long.

Given,

Scale on a blueprint says that 1 cm is the equivalent of 3 ft

1cm = 3ft

A particular line on the blueprint representing a wall measures 12 cm.

12cm = 12(3) ft

Wall is 36 ft long.

The act or system of measuring is referred to as measurement. It may be viewed as a procedure for utilizing numbers to define physical objects. "This rod is bigger than that rod," for instance.

Since we don't know anything about the specific characteristics of the provided rods, this statement only serves a very narrow function of comparison. However, if we claim that the first rod is 20 inches long and the second is 15 inches, the first rod will be 5 inches longer than the second.

An amount of 2 liters of the 30 % vinegar solution to obtain a 20 % vinegar solution.

According to the statement, a vinegar solution with a given concentration must be prepared by using two vinegar solutions with different concentrations. We can find the required addition of the 30 % vinegar solution by weighted averages, whose respective formula is:

(20 / 100) · (4 + x) = (30 / 100) · x + (15 / 100) · 4

0.2 · (4 + x) = 0.3 · x + 0.15 · 4

0.8 + 0.2 · x = 0.3 · x + 0.6

0.1 · x = 0.2

Sum of their ages= 53

Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign, −. For example, in the adjacent picture, there are 5 − 2 peaches—meaning 5 peaches with 2 taken away,

a-b = c (c may be a positive or negative value it may be 0 too)

given that, total of the ages of andrew, caren and barbara is 68 years

asked about their total 5 years back so we have to subtract five years from three of them then we will get,

3x5=15

subtract 15 from 68 to get total of their ages five years ago

68-15=53

Answer:

Ages together equal 53.

Step-by-step explanation:

An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol, or, denotes subtraction. For instance, the adjacent image shows 5 2 peaches, or 5 peaches with 2 subtracted.

a-b = c (c may have a positive, negative, or even zero value.)

Given that, Andrew, Caren, and Barbara's combined age is 68 years.

asked them how many years back in total they had, so we had to take away five years from three of them to get,

3x5=15

In order to calculate their ages five years ago, take 15 out of 68.

68-15=53

this reveals Andrew, Caren, and Barbara's combined ages. five years ago
