Integers are whole numbers, which van be positive and negative. Positive integers are the hole numbers greater than zero, while negative are the whole numbers smaller than zero.
The thermometer for example uses positive integers (temperature presented in degrees greater than 0 degrees Celsius: 25 <span>°C</span>, and negative integers (temperature below zero , example -15 °C) .
Answer:
w(2w+5) = 50
Step-by-step explanation:
length x width = 50
length = 2w+5
Answer: P = $ 1,998.01
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 24%/100 = 0.24 per year,
putting time into years for simplicity,
1 months ÷ 12 months/year = 0.083333 years,
then, solving our equation
P = 39.96 / ( 0.24 × 0.083333 ) = 1998.007992032
P = $ 1,998.01
The principal required to
accumulate interest of $ 39.96
on a rate of 24% per year for 0.083333 years (1 months) is $ 1,998.01.
Answer:

Step-by-step explanation:
<h3>Equation of the blue line:</h3>
since the line is horizontal and passes <u>-</u><u>2</u> the equation of the blue line should be

<h3>Equation of the red line:</h3>
remember The form of equation of a line

where m is slope of the line and b is the y-intercept we can clearly see that the red line crosses y-axis at (0,-3) therefore b=-3
to figure out m we can consider the following formula:

from the graph we acquire ∆y=1 and ∆x=2
thus substitute:

so we have figured out m and b
therefore our equation of blue line is

our given options are in standard form so
move -3 to left hand side and change its sign:

cross multiplication:

move 6 to right hand side and x to left hand side and change its sign

multiply both sides by -1:

hence, our system of linear equation is
