Write the equation of a line perpendicular to the line: y=−5/2x+4 that goes through the point (-6, 0).

Mathematics

NikAS [45]3 years ago
3 0

Step-by-step explanation:

the line given slope = x coefficient = -5/2

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

new slope = 2/5

line equation formula = y = mx+ b

m = slope

y= 2/5x + b

from the point given (-6,0)

x = -6

y = 0

0= -12/5 + b

b = +12/5

line equation =

y =  \frac{2}{5} x +  \frac{12}{5}

Karen works for 85 hours over a two week period. SHe earns $1,891.25 over this period. How much does Karen earn for 8 hours of w
Gekata [30.6K]
If karen works 85 hours within two weeks and earns $1,891.25, you'd set up an equation like this, to find the value of x ----

x=amount of money per hour Karen works 

85x=<span>1,891.25

then divide </span><span>1,891.25 by 85 

x=</span>22.25

this says that karen gets $22.25 for every hour she works.... then to find how much she works for 8 hours you want to multiply the amount of money she gets per hour by 8 hours. 

22.25 x 8 = 178

Karen earns $178 after working 8 hours.

Write the linear equation that gives the rule for this table.
Harlamova29_29 [7]

Answer:

The linear equation that gives the rule of the table is f(x) = x + 25

The linear equation can be represented in a slope intercept form as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

Using the table let get 2 points

(2, 27)(3, 28)

let find the slope

m = 28 - 27 / 3 -2 = 1

let's find b using (2, 27)

27 = 2 + b

b = 25

Therefore,

y = x + 25

f(x) = x + 25
