Answer:
a) y = -7x +1
Step-by-step explanation:
Slope-intercept form is ...
y = mx + b
The other forms shown are various ways this can be rearranged, but they are not slope-intercept form.
Answer: (2x + 32)(2x + 25) = 1600
Step-by-step explanation:
The former length of the rectangular plot = 32 feets
The former width of the rectangular plot =25 feets
The former area of the rectangular plot is former length of the rectangular plot × former width of the rectangular plot
= 32×25 = 800 feet^2
If the area is doubled, the new area would 800 × 2 = 1600 feet^2
If an equal width of x feets was added to each side of the plot,
The new length would be (32 + 2x) feets.
The new width would be (25 + 2x) feets. The 2x is due to the fact that there are 2 lengths and 2 widths
The new area would be
(2x + 32)(2x + 25) = 1600
Answer: A -22 can be a rational number as well as a integer
Step-by-step explanation:
Whole Number: A whole number is not a fraction or a decimal so a example would be: 43 or 85 or 1 or 3. Zero is not a whole number. Negative are not whole numbers
Rational number: A rational number is a number that can be expressed as a fraction or a decimal. Like 33 can be 33/1. Most numbers are rational. Zero is a rational number.
Integers: A integer is not a fraction or a decimal. its a positive or negative number. Example: 1 or -5 or 85 or -445. there is still some arguments about if zero is a integer.
Irrational numbers: A irrational number cannot be expressed as a ratio. So for example pi: 3.141592653589......(it keeps on going, we haven't even gotten to the end because its infinite).
Natural numbers: Natural numbers are positive numbers. Example: 1,6,3,4,62,3 etc. Sometimes zero is a natural number.
