8 0

Answer:

Step-by-step explanation:

1/2(10x-8)=1/3(21-15x)

Opening the brackets

5x - 4 = 7 - 5x

5x + 5x = 7 + 4

10x = 11

x = 11/10

x = 1 1/10

Find the slope of the line
Schach [20]

Answer:

The slope of the line is: 3

Step-by-step explanation:

Given the points

(-3, -6) and (3, 12)

Determine the slope between (-3, -6) and (3, 12) using the formula

m=\frac{y_2-y_1}{x_2-x_1}

where

m is the slope between (x₁, y₁) and (x₂, y₂)

In our case,

  • (x₁, y₁) = (-3, -6)
  • (x₂, y₂) = (3, 12)

now substitute (x₁, y₁) = (-3, -6) and (x₂, y₂) = (3, 12) in the slope formula

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{12-\left(-6\right)}{3-\left(-3\right)}

m=\frac{12+6}{3+3}

m=\frac{18}{9}

m=3

Therefore, the slope of the line is: 3

The parent function f(x) = x3 is translated to form g(x), as shown on the graph. The translated function can be written in the f
OLEGan [10]

Answer: First option

Step-by-step explanation:

By definition, the horizontal shift depends on the value of <em>h </em>and the vertical shift depends on the value of <em>k</em><u>.</u>

f(x)=(x-h)^3 indicates that the function if shifted to the right <em>h </em> units.

f(x)=(x+h)^3 indicates that the  function if shifted to the left <em>h </em> units.

f(x)=f(x)-k indicates that the  function if shifted  down <em>k </em> units.

f(x)=f(x)+k indicates that the  function if shifted up <em>k </em> units.

Then:

If <em>h </em>is positive, the graph will shift to the right.

If <em>k </em>is negative, the graph will shift down.

 As you can see in the graph, the function is shifted 4 units to the right and 2 units down. Therefore g(x) has the form:

 g(x)=(x-4)^3-2

Where:

h=4\\k=-2

Multiply the polynomials. (5x2 + 2x + 8)(7x – 6) A. 35x3 – 16x2 – 44x – 48 B. 35x3 – 14x2 + 44x – 48 C. 35x3 – 16x2 + 44x + 48 D
ZanzabumX [31]

Answer:

D) 35x³ - 16x² + 44x - 48

Step-by-step explanation:

(5x2 + 2x + 8)(7x – 6) = (5x2 + 2x + 8)* 7x + (5x2 + 2x + 8)*(– 6)

= (5x2*7x + 2x*7x + 8*7x) + (5x2*(-6) + 2x*(-6) + 8*(-6) )

=35x³ + 14x² + 56x - 30x² - 12x - 48

= 35x³ - 16x² + 44x - 48
