Chose the equation for a line that passes through (2,-3) and has a slope of m=-4 in point slope form.

### Answers

Answer:

y + 3 = - 4(x - 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 4 and (a, b) = (2, - 3), thus

y - (- 3) = - 4(x - 2), that is

y + 3 = - 4(x - 2)

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the functions are:-

f(x) = x² + 2x - 6

g(x) = (3x² - 5x - 7)

The value of the function will be calculated as:-

f(x) - g(x)

= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1

= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms

= - 2x² + 7x + 1

Therefore, the value f(x)-g(x) is -2x² + 7x + 1.

Answer:

- 2x² + 7x + 1

Step-by-step explanation:

f(x) - g(x)

= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1

= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms

= - 2x² + 7x + 1

### Answers

100*100*98+82/6*1500+200,000,999,982/108

= (100*100*98) + (82/6*1500) + (200,000,999,982/108)

= 980,000 + 20,500 + 200000999982/108

Reduce the last fraction:

= 980,000 + 20,500 + 33333499997/18

Hez is making a bookcase the boards that are used to make the bookcase are 13/16 inch thick Hez found a board that is 1 1/4 inches thick by how much does Hez have to reduce the thickness of the new board to match the other boards of the bookcase

### Answers

Hez have to reduce the thickness of the new board by 35% to match the other boards of the bookcase

Solution:

The boards that are used to make the bookcase are inch thick

Hez found a board that is inches thick

Let us consider that he has to reduce the n% of board

Then, thickness – n% of thickness = required thickness

On solving we get,

On simplification,

Hence, he has to reduce the board by 35%

The total number of students that failed in both subjects would be; 10 students.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given that class of 120 students 70 students passes in English 80 students passed in Hindi and 40 passed in both English and Hindi

The Students that passed English ; 70 - 40 = 30

The Students that passed Hindi; 80 - 40 = 40

The Total students that passed both subjects = 110 (40 + 40 + 30)

The students failed in both subjects;

120 - 110 = 10

The 30 and 40 students come from those who passed each subject above, then the extra 40 comes from the number of students that passed both.

The total number of students that failed in both subjects would be; 10 students.

Answer:

Total students that failed in both subjects would be 10

Step-by-step explanation:

Students that passed English : 70 - 40 = 30

Students that passed Hindi : 80 - 40 = 40

Total students that passed both subjects 110 (40 + 40 + 30)

120 - 110 = 10 students failed in both subjects

The 30 & 40 come from the students that passed each subject above, then the extra 40 comes from the amount of students that passed both.

A rectangular garden is to cover 468 square feet of area. If the width 8 feet less than the length find both dimensions, with the use of factoring

### Answers

Length of garden is 26cm and width is 18cm.

Step-by-step explanation:

Given,

Area = 468 Square feet

Let l be the length and w be the width.

According to statement;

w = l - 8 Eqn 1

Area = w*l = 468 Eqn 2

Putting Eqn 1 in Eqn 2

Solving the equation by factorization;

Either,

l+18=0 => l= -18

Or,

l-26=0 => l=26

As length cannot be negative, therefore,

l=26cm

w=

w=18cm

Length of garden is 26cm and width is 18cm.

if a bag contains 100 red cubes 50 blue cubes 25 yellow cubes and 25 green cubes what is the probability of khizra choosing a blue cube?

### Answers

The probability of Khizra choosing a blue cube is 0.25.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a bag contains 100 red cubes 50 blue cubes 25 yellow cubes and 25 green cubes.

Here, total number of outcomes = 100+50+25+25

= 200

Number of favorable outcomes = 50

Now, the probability of an event = 50/200

= 1/4

= 0.25

Therefore, the probability is 0.25.
