Answer:

x = -7 , 7

Step-by-step explanation:

a² - b² = (a + b)(a - b)

x² - 49 = 0

x² - 7² = 0

(x + 7)(x -7) = 0

x + 7 = 0         ; x - 7 = 0

x = -7             ; x = 7

Wich of the following is the correct graph of solution to the inequality -8 >-5x+2>-38
zimovet [89]
-5x + 2 > -38
-5x > -40
x < 8

-5x + 2 < -8
-5x < -10
x > 2

so the inequality becomes
2 < x < 8

so the graph will be a straight line with open circles on 2 and 8 and shading in between these values.

During the Last year:  (12 Months):

Cook Paid:

Little:   $23.04

Much:  $29.40, For Butter he or she purchased in a week:

Question: is: what is the Difference between, the Greatest price per pound, and the least price per pound of butter the cook paid within the last year?


EQUATION:

Least Paid / 12  =====>  23.04 /12

Most Paid / 12  ======>    29.40 / 12



Divide:

23.04 / 12    =     1.92 / LB

29.40 / 12     =     2.45 / LB

Now Subtract:

2.45   -     1.92

Answer   ======>    0.53 is the difference, between the greatest price per round, and least price per round of butter the cook would have paid within the last year.






Hope that helps!!!                                : )

Find the exact solution to the equation. Show your work for credit. (1 point) four to the power of quantity twelve minus four x
padilas [110]
4^(12-4x)=256  realize that 256 is 4^4  so we really have:

4^(12-4x)=4^4  taking the natural log of both sides

(12-4x)ln4=4ln4  dividing both sides by ln4

12-4x=4  subtract 12 from both sides

-4x=-8  divide both sides by -4

x=2
