Consider the equation and its solution.
8(x-2) = 64
8x-18-84
8x = 80
X=10
Which property is used in the last step to find thatx-10?
distributive property
addition property of equality
subtraction property of equality
division property of equality

Answers

Answer 1

Answer:

division property of equality

Step-by-step explanation:

The property used in the last step to find x = 10 in the expression is the division property of equality.

      8(x-2) = 64

      8x-18 = 84

        8x = 80

         x = 10

In 8x = 80 ;

 Division property of equality was used to find the value of x.

The property states that when we divide both sides by a non-zero value, the two sides remains the same.

The function f(x) = x^3 − x + 4, in continuous in the interval [1, 2]. Find the value of ‘x' at which the function takes the value 7. (Hint: Use f(x) = 7)

Answers

Answer:

2

Step-by-step explanation:

Given the function

f(x) = x^3 − x + 4 in the interval [1,2]

We are to find the value of x for which f(x) = 7

Substitute f(x) = 7 into the expression as shown!

f(x) = x^3 − x + 4

7 = x^3 − x + 4

x^3 − x + 4 -7 = 0

x^3 − x - 3= 0

x^3 -x = 3

x(x²-1) = 3

x²-1 = 3 and x = 3

x² = 3+1

x² = 4

x = ±√4

x = ±2

Since x lies within the interval, [1,2] hence the value of x is 2

This graph represents the linear relationship between time and distance for both Car 1 and Car 2.
Slope of Car 1 = 1 Speed of Car 1 = 1 mi

Speed of Car 2 = 1 mi 2 min
How can you determine by looking at the graph which car is moving at a faster rate? The the line, the the slope.
Car 1 is moving at a speed than car 2.

Answers

Answer:

Step-by-step explanation:

The steeper the line (graph), the greater the slope and the greater the speed of that particular car.  It is instantly obvious that of the two lines shown, the yellow graph has the greater slope and thus the greater speed.

"The steeper the line, the greater the slope(speed).  "Car 1 is moving at a speed than car 2."

A rectangle has a length that is 7 inches less that twice it's width. The area of the rectangle is 72 square inches. Write an equation that represents this solution.

Answers

Answer: [tex]2x^2-7x=72[/tex] , where  x= width of the rectangle ( in inches).

Step-by-step explanation:

Let x= width of the rectangle ( in inches).

Then its length =  2x-7 ( in inches).

Area of rectangle = Length × width

= (2x-7) × (x)

= 2x × x -7 ×x

= 2x²-7x

The area of the rectangle is 72 square inches.

[tex]\Rightarrow\ 2x^2-7x=72[/tex]

Hence, the equation that represents the given situation :

[tex]2x^2-7x=72[/tex]

Answer:

p = 3, q = 2/3, r = 14/3

Step-by-step explanation:

Given equationy = 3x² - 4x + 6To find

The constants p, q, r when

3x² - 4x + 6 = p(x - q)² + rSolution

The least value is at vertex of the parabola ax² + bx + c, with positive a

x and y -coordinates of the vertex is:

x = -b/2a = - (-4)/(2*3) = 2/3y = 3(2/3)² - 4(2/3) + 6 = 3(4/9) - 8/3 + 6 = 4/3 - 8/3 + 6 = 14/3

The vertex form is:

y = a(x-h)² + k, where (h, k) is the vertex

Applying the same formula to our equation:

3x² - 4x + 6 = 3(x - 2/3) + 14/3

The constants p, q and r are:

p = 3, q = 2/3, r = 14/3
