Answer:

The roots of the equation is real and repeated

Step-by-step explanation:

Here, we want to describe the nature of the roots of the given quadratic equation

To get the nature of the roots, we find the discriminant of the equation

The discriminant is;

b^2 - 4ac

In this case, b = -28 , a = 49 and c = 4

The discriminant is thus;

-28^2 - 4(49)(4)

= 784 - 784 = 0

Since the discriminant is zero, this means that the quadratic equation has real roots which are the same

Answer:

2

Step-by-step explanation:

Use BODMAS(bracket, of, division, multiplication, addition and subtraction)

72/8=9

(6*4)=24

24/12+9-9

2+0

=2

The solution for the given operations of numbers is 2.

PEMDAS rule is the same as BODMAS rule.

PEMDAS is the abbreviation for Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.

We are using BODMAS rule here to solve the given operations.

6 * 4 ÷ 12 + 72 ÷8 - 9

According to the rule, first we should do multiplication.

6 × 4 = 24

6 * 4 ÷ 12 + 72 ÷8 - 9 = 24 ÷ 12 + 72 ÷8 - 9

Next do the division.

24 ÷ 12 = 2 and 72 ÷8 = 9

24 ÷ 12 + 72 ÷8 - 9 = 2 + 9 - 9

Now do the addition and subtraction.

2 + 9 - 9 = 2

Hence the final answer for the given operation is 2.

Step-by-step explanation:

The probability the arrows will land on a consonant and the number 2 is,  10%

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Given that;

Elizabeth spins each spinner once.

Hence, Number of outcomes for Alphabets = 5

And, Number of outcomes for numbers = 6

Total consonants are = 3

Thus, The probability the arrows will land on a consonant and the number 2 is,

⇒ 3 / 5 × 1 / 6

⇒ 1 / 10

⇒ 10%

Therefore, The probability the arrows will land on a consonant and the number 2 is, 10%

Answer: B. X+26<2x+16

Step-by-step explanation:

Let x be the number of lemonade Kaylee needs to sell to make a higher profit than Jason.

Given: Jason has made $26. he charge $1 per lemonade.

Total earnings after x lemonades = $26+($1) x

= $(26+x)

Kaylee has made $16. he charge $2 per lemonade.

Total earnings after x lemonades = $16+($2) x

= $(16+2x)

Required inequality : (16+2x)> (26+x)

i.e. correct option is B.

Answer:

There are infinite solutions

Step-by-step explanation:

They equal each other meaning they are infinite solution

Answer:

what is the question tho

Answer:

−2(−9x+5)−4x=2(x−5)−4

Step 1: Simplify both sides of the equation.

−2(−9x+5)−4x=2(x−5)−4

(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)

18x+−10+−4x=2x+−10+−4

(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)

14x+−10=2x+−14

14x−10=2x−14

Step 2: Subtract 2x from both sides.

14x−10−2x=2x−14−2x

12x−10=−14

Step 3: Add 10 to both sides.

12x−10+10=−14+10

12x=−4

Step 4: Divide both sides by 12.

Answer:

(-4,-6)

Step-by-step explanation:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The point of intersection between the two equations is (-4, -6).

The graph is given below.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 6 is an equation.

We have,

y = 2x + 2

y = x - 2

Now,

The point of intersection.

2x + 2 = x - 2

2x - x = -2 - 2

x = -4

Putting in y = 2x + 2

y = 2 x -4 + 2

y = -8 + 2

y = -6

(-4, -6) is the point of intersection.

Now,

The graph of the equation is given below.

Thus,

The point of intersection between the two equations is (-4, -6).

Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

144 students enter a spelling bee contest.

Step 1

For the semi final round we are told that only 1/6 of the group will make it into that round.

This is calculated as

1/6 × 144/students = 24 students.

This means that only 24 students would make it into the semi final rounds.

Step 2

We are also told in the question that only 2/3 of THAT group would make it into the final round.

" THAT" group been referred to in the question means the number students that made it to the semi final round

This is calculated as

2/3 of that group( the group that made it to the semi finals)

= 2/3 × 24 students

= 16 students.

Therefore, the number of students that will enter the final round of the spelling bee is 16 students.
