Log4(x^2 + 6x +8) - log4 ( x+2)
vaieri [72.5K]
Since the logarithms have the same base, we can simply divide (x^2 + 6x + 8) by (x+ 2) and just retain the sme base. So, the answer will be Log4(x+4)

The test scores for 8 students taking and algebra 1 test are as follows: 56, 92, 78, 64, 85, 83, 91, 77. what would the 9th stud
crimeas [40]
X= 9th student test score

Add the 9 test scores and divide that total by 9 to equal the average.


(56 + 92 + 78 + 64 + 85 + 83 + 91 + 77 + x)/9= 78
add in parentheses

(626 + x)/9= 78
multiply both sides by 9

626 + x= 702
subtract 626 from both sides

x= 76


ANSWER: 76 is the score needed by the 9th student for a mean of 78.

Hope this helps! :)

Find the x-intercepts of the parabola with
12345 [234]

Answer:

x-intercepts are (0, 0) and (-6, 0)

Step-by-step explanation:

equation of a parabola in vertex form:  y = a(x - h)² + k

where (h, k) is the vertex

Substituting the given vertex (-3, -18) into the equation:

y = a(x + 3)² - 18

If the y-intercept is (0, 0) then substitute x=0 and y=0 into the equation and solve for a:

0 = a(0 + 3)² - 18

⇒ 0 = a(3)² - 18

⇒ 0 = 9a - 18

⇒ 9a = 18

⇒ a = 2

Therefore, y = 2(x + 3)² - 18

To find the x-intercepts, set the equation to 0 and solve for x:

                                 2(x + 3)² - 18 = 0

Add 18 to both sides:     2(x + 3)² = 18

Divide both sides by 2:    (x + 3)² = 9

Square root both sides:      x + 3 = ±3

Subtract 3 from both sides:  x = ±3 - 3

so x = 3 - 3 = 0  

and  x = -3 - 3 = -6

So x-intercepts are (0, 0) and (-6, 0)
