8 0

Answer:

- 8

Step-by-step explanation:

Given

(4 +4 x²)(3x² - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

4(3x² - 5) + 4x²(3x² - 5) ← distribute parenthesis

= 12x² - 20 + 12x^{4} - 20x² ← collect like terms

= 12x^{4} - 8x² - 20

with coefficient of x² term being - 8

never [62]

Answer: 4 and 1 over 2 ÷ 1 over 8


Step-by-step explanation:

Given that : Total distance drove by Parker =4 and 1 over 2 miles=4\frac{1}{2} miles

Distance drove by Parker each day = 1 over 8 mile=\frac{1}{8} mile

To find the total number of days , we need to divide the total distance by the distance drove by him in each day.

Thus, the number of days he went driving=4 and 1 over 2 ÷ 1 over 8

A line passes through (2, 8) and (4, 12). Which equation best represents the line? y = 1 over 2 x 6 y = 2x 7 y = 2x 4 y = 1 over
nalin [4]

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

Given information-

The point through which the line passes are (2, 8) and (4, 12).

To find the equation of the line, the standard form of the equation of the line must be obtained.

<h3>Equation of the line</h3>

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

The standard form of the equation of the line can be given as,

(y-y_1)=\dfrac{y_2-y_1}{x_2-x_1} (x-x_1)

Where (x_1,y_1) and (x_2,y_2) are the points through which the line passes.

Thus the equation of the line which passes through the points (2, 8) and (4, 12) can be given as,

(y-8) &=\dfrac{12-8}{4-2} (x-2)\\(y-8) &=\dfrac{4}{2} (x-2)\\2y-16 &=4x-8\\2y &=4x-8+16\\

Divide by 2 both the side,

y=2x-4

Thus the equation of the line which passes through the points (2, 8) and (4, 12) is,

y=2x-4

Hence the option 3 is the correct option.
