Here are six number cards.-4 -2 -1 5 6 8
Arrange the cards into three pairs with the same total.
Note: Please write each pair on separate lines and
use the word 'and' between the numbers (eg. 7 and -3).
Answers
Answer:
See explanation
Step-by-step explanation:
The first pair is (-4 and 8)
Because if we add those two values, i. e., 8 + (-4), we will get 4.
Again, the second pair is (-2 and 6). In that case, if we also add those two values, that is, 6 + (-2), we will get 4.
Finally, the third pair is (-1 and 5). Again, we will add the two values. 5 + (-1) = 4.
In each case, we can see that the addition of each pair is 4.Therefore, the total is similar in each pair after arranging the cards.

P = (5x - 7) + (3x - 4) + (2x - 6) Remember to add like-terms, start with all the numbers with x next to them.
P = (5x + 3x + 2x) + (-7 + -4 + -6)
P = (10x) + (-17) Then, combine them back into one equation.
P = 10x - 17, so answer choice A.
4. The problem wants you to find the volume of the driveway, which is how much concrete will fit in it. You can find the volume with the equation (volume = width x height x length).
V = W x H x L Substitute the variable for the dimensions. (height = depth)
V = 6 x 1/3 x 162 I changed 4 inches to 1/3 ft so that all the values will be in feet.
V = 2 x 162
V = 324 ft³, so answer choice B.

find the domain
Answers
Answer:
x >= -7 ................(1a)
x >= 3 ...............(2a1)
Step-by-step explanation:
f(x) = .............(0)
find the domain.
To find the (real) domain, we need to ensure that each term remains a real number.
which means the following conditions must be met
x+7 >= 0 .....................(1)
AND
x^2+2x-15 >= 0 ..........(2)
To satisfy (1), x >= -7 .....................(1a) by transposition of (1)
To satisfy (2), we need first to find the roots of (2)
factor (2)
(x+5)(x-3) >= 0
This implis
(x+5) >= 0 AND (x-3) >= 0.....................(2a)
OR
(x+5) <= 0 AND (x-3) <= 0 ...................(2b)
(2a) is satisfied with x >= 3 ...............(2a1)
(2b) is satisfied with x <= -5 ................(2b1)
Combine the conditions (1a), (2a1), and (2b1),
x >= -7 ................(1a)
AND
(
x >= 3 ...............(2a1)
OR
x <= -5 ................(2b1)
)
which expands to
(1a) and (2a1) OR (1a) and (2b1)
( x >= -7 and x >= 3 ) OR ( x >= -7 and x <= -5 )
Simplifying, we have
x >= 3 OR ( -7 <= x <= -5 )
Referring to attached figure, the domain is indicated in dark (purple), the red-brown and white regions satisfiy only one of the two conditions.
