Use an equation to find the value of k so that the line that passes through (-2,k) and (2,0) has a slope of m=-1

Mathematics

6 0

Answer:

The value of k is 4.

Step-by-step explanation:

To find the missing coordinate, we can use the slope equation and plug in all known values.

m(slope) = (y2 - y1)/(x2 - x1)

-1 = (k - 0)/(-2 - 2)

-1 = k/-4

Now we can solve using cross multiplication.

-1 = k/-4

k*1 = -1*-4

k = 4

An anthropologist studies a woman's femur that was uncovered in Madagascar. To estimate the woman's height, he uses the equation
Norma-Jean [14]

Answer:

The inequality best represents the length of the femur that would suggest the woman had a height greater than 160 cm is:

f > 40

Step-by-step explanation:

Woman's height (cm): h = 60 + 2.5 f

Length of the femur (cm): f


Height greater than 160 cm:

h > 160

Replacing h by 60+2.5f in the inequality above:

60+2.5f > 160

Solving for f: Subtracting 60 both sides of the inequality:

60+2.5f-60 > 160-60

Subtracting

2.5f > 100

Dividing both sides of the inequality by 2.5:

2.5f/2.5 > 100/2.5

f > 40

Answer: The inequality best represents the length of the femur that would suggest the woman had a height greater than 160 cm is:

f > 40

Teresa makes 9 dollars for each hour of work. Write an equation to represent her total pay p after working h hours
Butoxors [25]

Answer:

P=9h

Step-by-step explanation:

Since Teresa makes 9 dollars for each hour of work, we can say:

9 dollars/1 hour.

Her total pay will be on one side of the equation:

p=

Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:

h hours

Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.

p=9h
