h) -11√2
Explanation:
You are combining all of the like terms, which are the terms with the same number underneath the radical.
Answer:
10. 0
11. -16
12. 2
13. 2
14. 3
15. 0
Step-by-step explanation:
10. (x+4)(x-4) --> x= 4, -4 --> 4 + (-4) = 0
11. 4(-4) = -16
12. 2(x-2)² --> x = 2
13. 2
14. x(x-3) --> x= 0, 3, 0+3=3
15. 0(3) = 0
Answer:
Step-by-step explanation:
first we need to find the slope bu using the slope formula and ur two sets of points
slope = (y2 - y1) / (x2 - x1)
(7,1)...x1 = 7 and y1 = 1
(-12,-6)....x2 = -12 and y2 = -6
now we sub
slope = (-6 - 1) / (-12 - 7) = -7/-19 = 7/19
now...in y = mx + b form, the slope will be in them position
y = mx + b
slope(m) = 7/19
use either of ur points.....(7,1)...x = 7 and y = 1
now we sub and find b, the y int
1 = 7/19(7) + b
1 = 49/19 + b
1 - 49/19 = b
19/19 - 49/19 = b
- 30/19 = b <======= ur y int
so ur equation is : y = 7/19x - 30/19

Answer:
<u><em>THE ANSWERS ARE OPTION C and E</em></u>
Step-by-step explanation:
so there are 3 different types of loaves .
the price of french bread is 
;
from the question , we find that the price of wheat bread is twice of that of the french bread. thus ,
the price of wheat bread is 
;
the price of cinnamon raisin bread is $2.50 more than the wheat bread. thus ,
the price of cinnamon raisin bread is 
;
<em>now the total amount she spent was : $11.25</em>
thus ,
which gives us ,
<em><u>∴ The correct answers are C and E</u></em>
