LCD is least common denominator. So looking at the denominators, their factors are...
First term x^2 - 5x + 4 = (x - )( x - ). We know this because the 4 (c term)is + so both signs are the same, and both are NEGATIVE because 5 (b term) is -
= (x - 4)(x - 1) because(-1)(-4) = 4 (c term) and -1 + -4 = -5 (b term)

Jake is a factory manager for a company that produces batteries. Occasionally, some are found to be defective. Based on previous
Aleksandr [31]

Based on the estimated number of defective batteries and the number of batteries that were actually defective, the percent error of Jake's estimate is 20%

<h3>How to find the percent error?</h3>

The percent error of a problem can be found by the formula:
= (Expected results - Actual results) / 100%

Expected results = 12 defective batteries

Actual results = 10 defective batteries

Jake's percentage error is therefore:

= (12 - 10) / 100%

= 2 / 10 x 100%

= 0.2 x 100%
= 20%

In conclusion, the percent error of Jake's estimate is 20%.

A line passes through the point (0,5) and has a slope of -1/2 which is the equation of the line in slope intercept form?
Nana76 [90]

equation of line in slope intercept form is

y = mx + c

where m is slope.

putting point (0,5) in equation

5 = m × 0 + c

c = 5

now equation is

y = mx +c

y = (-1/2)x + 5

answer is option D

Step-by-step explanation:

We assume that the advertising rates in this journal for full-page ads is x ($/ad); the rate for half-page ads is y ($/ad).

The revenue for 3 full page ads are: 3x ($)

The revenue for 5 half page ads are: 5y ($)

One issue of a journal has 3 full-page ads and 5 half-page ads, generating $6340.

=> The total revenue for 3 full page and 5 half page ads are $6340

=> 3x + 5y = 6340

The revenue for 4 full page ads are: 4x ($)

The revenue for 4 half page ads are: 4y ($)

One issue of a journal has 4 full-page ads and 4 half-page ads, generating $6625.

=> The total revenue for 4 full page and 4 half page ads are $6625

=> 4x + 4y = 6625 (1)

We have:

+) 3x + 5y = 6340

=> 5y = 6340 - 3x

=> y = (6340 - 3x)/5 = 1268 - 0.6x

Replace <em>y = 1268 - 0.6x </em>into (1), we have:

4x + 4y = 6625

⇔4x + 4(1268 - 0.6x) = 6625

⇔ 4x + 5072 - 2.4x = 6625

⇔ 1.6x = 1553

⇔ x = 1553/1.6 = 970.625

=> y = 1268 - 0.6x = 1268 - 0.6*970.625= 1268 - 582.375 = 685.625

So the advertising rate for full page ads is $970.625, for half-page ads is $685.625
