Answer:
A. y = 2x -9
B. y = -1/2x +1
Step-by-step explanation:
The given line is in slope-intercept form
y = mx + b
where m is the slope. For your given line, the slope is 2.
A. A parallel line will have the same slope. It is convenient to start with a point-slope form of the equation for the line:
y = m(x -h) +k . . . . . for slope m through point (h, k)
You want the equation of the line through (4, -1) with slope 2, so its equation is ...
y = 2(x -4) -1
Simplifying to slope-intercept form, this becomes ...
y = 2x -8 -1
y = 2x -9
___
B. A perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line. That slope is ...
m = -1/2
As above, the point-slope form of the perpendicular line is ...
y = -1/2(x -4) -1
y = -1/2x +1 . . . . . after simplification
Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100.
22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.
Answer:
the answer is B

Answer:
Step-by-step explanation:
Smallest and largest whole number which gives 1600 when rounded to the nearest hundred.
The lowest whole number is 1550
The highest while number is 1649
Wheb rounding to the nearest hundred, the tens value which comes after the hundred value is carefully observed, of the tens value is less than 5, then it is rounded down to zero. However, if the tens value is greater than or equal to 5, it is rounded to 1 and added to the hundred value.
Numbers below 1550 will not round to 1600 (nearest 100) also numbers greater than 1649will not round to 1600(nearest 100).butvall numbers in between them will round to 1600 (nearest hundred)
