Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.

Given:

2m -3 = 3/10 (5m - 12)

Now, cross multiplying

10( 2m -3)= 3( 5m -12)

20m -30 = 15m - 36

20m- 15m= -36 + 30

5m = -6

Divide both side by 5

m= -6/5

Verification:

LHS = 2m-3

=2(-6/5)-3

=-12/5-3

=-27/5

and, RHS

= 3/10( 5m -12)

=3/10(5 x (-6/5) -12)

=3/10 (-6 - 12)

=3/10 x -18

= -54/10

= -27/5

Procedure:

0. Using the following formula we can get our probability.

a)

The slope intercept equation of a line is expressed as

y = mx + c

where

m is the slope

c is the y intercept

The given equation is

x + y = 3

y = - x + 3

By comparing both equations,

m = - 1

If two equations are parallel, it means that they have the same slope. Thus, the slope of the parallel line passing through the point (- 3, 2) is - 1

We would find the y intercept by substituting x = - 3, y = 2 and m = - 1 into the slope intercept equation. It becomes

2 = - 1 * - 3 + c

2 = 3 + c

c = 2 - 3

c = - 1

By substituting m = - 1 and c = - 1 into the slope intercept equation, the equation of the line is

y = - x - 1

b) If two equations are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line Thus, the slope of the perpendicular line passing through the point (- 3, 2) is - - 1/1 = 1

We would find the y intercept by substituting x = - 3, y = 2 and m = 1 into the slope intercept equation. It becomes

2 = 1 * - 3 + c

2 = - 3 + c

c = 2 + 5

c = 5

By substituting m = 1 and c = 5 into the slope intercept equation, the equation of the line is

y = x + 5

a) y = - x - 1

b) y = x + 5

The value is x≤1 or x>2

Equations don't always need to have a "equal to" symbol on both sides to be balanced. Sometimes it can be about a "not equal to" relationship, meaning that something is superior to or inferior to another. In mathematics, an inequality is a relationship between two numbers or other mathematical expressions that results in an unequal comparison. Inequalities are the name given to certain algebraic mathematical expressions.

Answer:

43

Step-by-step explanation:

The value of y varies directly with x. When y = 21, x = 3. What is the value of y when x is 14.

when y = 21 and x = 3 the ratio of y to x is 21 to 3 or (reduced) 3 y to 1 x

This means y is three times the size of x.

When x = 14 then y = 14 × 3 = 42

Answer:99cm.l

Step-by-step explanation:100-1

100-1=99

So then the answer is 99, because 99+1 is also equal to 100.

And if you subtract 1 from 100, you get 99.

Answer: 99cm

Step-by-step explanation:

1cm + x = 100cm

100cm - 1cm = x
Which means,

99cm is the correct answer.

From the figure given in the question, we are asked to find the area and perimeter.

(a) Area:

Since the figure is a trapezoid, the formula for the area of a trapezoid is:

Area = (a + b)h

2

Where:

a = 2

b = 5

h = 4

Area = (2 + 5)4

2

Area = 7/2 * 4

Area = 3.5 * 4

Area = 14 cm²

(b) Perimeter:

To get the perimeter, we will have to add all the side length.

But we will have to find the missin side length first.

Using pythagoras:

a² + b² = c²

Where:

a = 4

b = 3

c² = 4² + 3²

c² = 16 + 9

c² = 25

Taking square of both sides:

c = √25

c = 5

Since we have gotten the missing side length as 5cm, we can now add all the given side length to get the perimeter.

Perimeter = 4 + 2 + 5 + 5

Perimeter = 16 cm

A temperature drop of 7 degrees Fahrenheit in 3.5 hours is represented by 2 f/hour.

Fahrenheit temperature scale, based on the freezing point of water at 32° and the boiling point of water at 212°, with the interval between the two divided into 180 equal parts.

Given: The outside temperature drops by 7 degrees Fahrenheit in 3 1/2 hours.

We need to represent the temperature as a unit.

To do so, we must represent the temperature change per hour.

7f/3.5 hours = 2 f/hour

Therefore, the temperature that decreases by 7 degrees Fahrenheit in 3.5 hours can be represented as 2 f/hour.

The three methods that are generally used to solve f(x) =g(x) are Graphing technology, Tables of values, and Successive approximation.

Determine the exact value of x by replacing the values of x with f(x) and g(x).

The hit-and-trial technique is used in f(x) = g(x) to compute the exact value of x by selecting an interval and then substituting the value of x in that interval.

This is a bit longer and takes more time.

Graph Technique: Create a graph that contains both f(x) and g(x). The values of x given by these two functions are the same.  Some features are difficult to plot, but once plotting is done, the right solution is obtained. The graphics technique is prioritised in determining f(x) = g(x) and x.

The refrigerator is to be set at 5 degrees celsius for the cheese to keep for 5 days.

Since we are given the relation for the exponential function

H(T) = 130 (1/2) ^(T/43.3), where H(T) is the  number of hours

since we are asked for a cheese to keep for  5 days, so

H(T)=  5 * 24 = 120 hours

so the equation we will have

=>120 =130 (1/2) ^(T/43.3)

we multiply both sides by 120

=> 12/13=  (1/2) ^(T/43.3)

taking logarithms on both sides, we get

=> ln (12/13) = (T/43.3) ln(1/2)

=>43.3 ln (12/13) = T ln (1/2)

dividing both sides by ln (1/2), we get

=> T = 43.3  ln (12/13) / ln (1/2)

=> T=  5.0016

=> T = 5.0 celsius

Answer: Slope of 1.

Step-by-step explanation:

    First, we will put the equation into slope-intercept form.

x - y = 4

x = y + 4

y = x - 4

    Our slope, when the line is written as y = mx + b, is the m value. Our m value here is one, so the slope of a line parallel to the line whose equation is x - y = 4 is 1.
