Answer:

The predicted value of x = 2

Step-by-step explanation:

y = 4.2x - 3 is the given equation.

Now, y = 5.4

Putting in the above equation, we get

5.4 = 4.2x - 3

or, 5.4 + 3 = 4.2x

or, 8.4 = 4.2 x

⇒ x  = 8.4/4.2

⇒ x = 2

Which expressions are polynomials?
Oduvanchick [21]

Answer:


Step-by-step explanation:

Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in y^{2}), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.

1. 6 + p

Being p be a variable this equation is polynomial

2.  x – 1

Since x-1 has variable and constant so according to definition it is a polynomial

3. 8x−z3

According to definition it is a polynomial

4 .5x^{2}-x\sqrt{}

Since has root so it is not a polynomial .

Solve each equation. Be sure to check your solution.<br> 0.3a = 51
Aleksandr-060686 [28]

Answer:

a = 170

Step-by-step explanation:

0.3a = 51

a = 51 : 0.3

a = 51 : 3/10

a = 51 x 10/3

a = 510/3

a = 170

0.3x170 =

= 3/10x170

= 510/10

Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $1
Olenka [21]

Answer:

\$16,826,000.

Step-by-step explanation:

We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.

To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:

\text{Net profit for the year}=\$28,951,000+\$20,570,000+\$15,342,000-\$48,037,000

\text{Net profit for the year}=\$64,863,000-\$48,037,000

\text{Net profit for the year}=\$16,826,000

Therefore, the net profit for the year was \$16,826,000.
