2x-2=4x-6

Subtract 4x from both sides of the equation

-2x-2=6

Add two to both sides of the equation.

-2x=8

Devide by -2

x=-4

If f(t) = 2t3 find each value.<br> f(4)<br> 3[f(t)]

quester [9]

The value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.

<h3>What is polynomia?</h3>

To calculate the polynomial expression below, we use the technique below.

From the question,

Given:

f(t) = 2t³.............. Equation 1

To find f(4) we substitute 4 as the value of x in equation 1

f(4) = 2(4³)
f(4) = 512.

To find 3[f(t)] we multiply equation 1 by 3

3[f(4)] = 3(2t³) = 6t³

Hence, the value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.

Find the distance between (-7, -2) and (11,3). Write your answer to one decimal.<br> Your answer

scoray [572]

Answer:

<h3>The answer is 18.7 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7, -2) and (11,3).

The distance between them is

$d = \sqrt{( { - 7 - 11})^{2} + ({ - 2 - 3})^{2} } \\ = \sqrt{ ({ - 18})^{2} + ( { - 5})^{2} } \\ = \sqrt{324 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = \sqrt{349} \: \: \: \: \: \: \: \: \\ = 18.681541692... \: \: \: \: \:$

We have the final answer as

<h3>18.7 units to the one decimal place</h3>

Hope this helps you
