Answer:

The answer is B

Step-by-step explanation:

3x - 2x^2 + 3 -(-5x^2 + 3x + 5)

3x - 2x^2 + 3 + 5x^2 - 3x - 5

= 3x^2 - 2

[tex]\\ \sf\longmapsto Discount=\dfrac{12.5(30}{100}[/tex]

[tex]\\ \sf\longmapsto Discount=12.5(0.3)[/tex]

[tex]\\ \sf\longmapsto Discount=125(3)/100[/tex]

[tex]\\ \sf\longmapsto Discount=375/100[/tex]

[tex]\\ \sf\longmapsto Discount=3.75[/tex]

Answer:

discount = $3.75

Step-by-step explanation:

Given:

[tex]\sf \dfrac{discount \times 100}{100}=\dfrac{\$12.50 \times 30}{100}[/tex]

Multiply both sides by 100 to eliminate the denominators:

[tex]\implies \sf discount \times 100=\$12.50 \times 30[/tex]

Divide both sides by 10:

[tex]\implies \sf discount \times 10=\$12.50 \times 3[/tex]

Carry out the multiplication on the right side:

[tex]\implies \sf discount \times 10=\$37.50[/tex]

Divide both sides by 10:

[tex]\implies \sf \dfrac{discount \times 10}{10}=\dfrac{\$37.50}{10}[/tex]

[tex]\implies \sf discount=\$3.75[/tex]

Answer:

2 imaginary roots

Step-by-step explanation:

The discriminate is the portion of the quadratic equation under the square root

D = b^2 - 4ac

D = 8^2 - 4(2)(16)

D = 64 - 128

D = -64

Since the discriminate is negative the square root will be imaginary

and there will be 2 of them

2 imaginary roots

9514 1404 393

Answer:

Step-by-step explanation:

The discriminant of ax² +bx +c = 0 is b²-4ac. Here, we have ...

  a=2, b=8, c=16

so, the discriminant is 8² -4(2)(16) = 64 -128 = -64

A negative discriminant indicates there are two conjugate complex roots.

Answer:

Step-by-step explanation:

take b, divide it by 2 and then square it

(6/2)²=9 so add then subtract 9

(x²+6x+9)+3-9

The value of function for given x value is -1.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is f(x)=-(x+8)²-1.

Substitute x=-8 in the given function, we get

f(-8)=-(-8+8)²-1

= -0-1

= -1

Therefore, the value of function for given x value is -1.

He was earning 3562 each hour.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Kyle Lowry earned $31.2 million.

So, In each month he read

= 31200000 / 12

= $2,600,000

and, in each day she earn

= 2, 600, 000 / 30

=86,666.666

and, in each hour she earn

= 2, 600, 000 / 24

= 3611

Hence, He was earning 3562 each hour.

Answer:

B

Step-by-step explanation:

(5x - 2)² + 35x - 14 = - 12 ( factor out 7 from each term in 35x - 14 )

(5x - 2)² + 7(5x - 2) = - 12 ( add 12 to both sides )

(5x - 2)² + 7(5x - 2) + 12 = 0

Substitute m = 5x - 2 into the equation then in terms of m, the equation is

m² + 7m + 12 = 0 → B

The flat screen TV that is marked up by 30% and 20% discount had a profit of $60 after being sold.

The mark up percentage is given by:

Mark up percentage = (selling price - cost price)/cost price

Since the original price is $1500, hence:

30% = (selling price - 1500)/1500

0.3 = (selling price - 1500)/1500

(selling price - 1500) = 450

Selling price = $1950

It was again sold at a discount of 20%:

Final selling price= 1950 - 20% of 1950 = 1560

Profit = 1560 - 1500 = $60

Hence $60 profit was made by the store for the sale of a flat screen TV.

When adding, you only add the numerators. The denominator stays the same (Assuming the denominators are the same number). If not, then you will have to find a common denominator first. IN this case, the denominator is already the same. Add the numerator

2/3 + 2/3 = 4/3

Note that the answer gotten is an “improper fraction”, because the numerator is greater than the denominator. Simplify.

4/3 = 3/3 + 1/3

Divide: 3/3 = 1

1 + 1/3 = 1 1/3

1 1/3 is your mixed fraction answer (4/3 for improper fraction answer)

1cup=558/6

1cup=93 gram

13gram*17kg=221gram

221/93=2.38

Step-by-step explanation:

First we have to same the bases.

As we know 8=2^3.

Replace 8 with 2^3.

Like this .

2^3x=2^3(2x+1).

Now 3x=3(2x+1) distribute 3 by the Barker.

3x=6x+3.

6x+3=3x.

6x-3x=-3.

3x=-3.

X=-1.
