1.

2\cdot x^2+2\cdot x^1+1\cdot x^0=25\\2x^2+2x+1=25\\2x^2+2x-24=0\\x^2+x-12=0\\x^2+4x-3x-12=0\\x(x+4)-3(x+4)=0\\(x-3)(x+4)=0\\x=3 \vee x=-4

The base can't be negative, therefore x=3.

2.

3\cdot x^0+3\cdot x^1+4\cdot x^0-4\cdot x^1+0\cdot x^0=0\\3+3x+4-4x=0\\x=7

3.

2\cdot x^1+3\cdotx^0=1\cdot 2^3+1\cdot2^2+1\cdot2^1+1\cdot2^0\\2x+1=8+4+2+1\\2x=14\\x=7

On a number line what is the distance between -3/2 and 6?
sesenic [268]

Answer:

  • 7.5 units

Step-by-step explanation:

The distance is always positive and is same as the absolute value of subtraction of the two numbers on the line.

<u>This can be shown as:</u>

  • |-3/2 - 6| =
  • |-1.5 - 6| =
  • |-7.5| =
  • 7.5

or

  • | 6 - (-3/2)| =
  • |6 + 1.5| =
  • |7.5| =
  • 7.5

Fill in the y values of the t-table for the function<br> y=3√x.
Lorico [155]

The table of values of the function y = ∛x is

x      y

-8    -2

-1      -1

0      0

1       1

8     2

<h3>How to fill in the y values?</h3>

The function is given as:

y = ∛x

When x = -8, we have:

y = ∛-8 = -2

When x = -1, we have:

y = ∛-1 = -1

When x = 0, we have:

y = ∛0 = 0

When x = 1, we have:

y = ∛1 = 1

When x = 8, we have:

y = ∛8 = 8

So, the table of values is

x      y

-8    -2

-1      -1

0      0

1       1

8     2
