The number is 6860
The number 6 goes in both boxes
y = her salary,
m = rate of commission,
x = amount of merchandise sold
b = monthly base pay
sets of data to calculate the formula
(500, 405) and (900, 489)
use the slope formula to find m:
(489 - 405) / (900 - 500)
m= 84 / 400 = 0.21 (21% commission)
find the base pay by substituting known values for x,y, and m, then solve for b:
405 = (0.21)(500) + b
405 = 105 + b
b = 300
now we know the equation for her salary is:
y = 0.21x + 300
To find the salary when she sells $1,700 worth of merchandise, put 1700 for x and solve for y:
y = 0.21(1700) + 300 = 657
Answer:
the average diastolic blood pressure for adults is 120/80 mmHg
Step-by-step explanation:
Usually the 120/80 is very normal and anything under 110/70 is very dangerous and anything over 140/90 is dangerous as well
Hello!
To find the line perpendicular to the given line, y = 2x + 3, firstly, find the slope of the perpendicular line. To find it, use this format: -1/m, where m is the slope. It is also called the "negative reciprocal" of the slope of the given line.
Then, you substitute an ordered pair into a new slope-intercept equation (with the slope) and find the y-intercept.
-1/m when m = 2 → -1/2
y = -1/2x + b (substitute the given ordered pair)
-3 = -1/2(2) + b (simplify)
-3 = -1 + b (add 1 to both sides)
-2 = b | The y-intercept of the perpendicular equation is -2.
Therefore, the line perpendicular to the given equation, that also goes through the given ordered pair is y = -1/2x - 2.
