Which of the following expressions is equal to
-5 for some value of x?
A) |x - 6| + 2
B) |x - 2|-6
C) |x+2|+6
D) |x + 6|-2
Answers
===========================================================
Explanation:
Recall that for y = a| x-h | + k, the vertex is (h,k).
Since all of the answer choices have a > 0, this means all of the vertexes are the lowest point for each absolute value graph.
Consequently it tells us the lowest possible y value.
For choice A, the smallest y output possible is y = 2For choice B, it would be y = -6For choice C, y = 6 is the lowestAnd choice D says y = -2 is the lowest y valueChoices A, C and D indicate that getting y = -5 is impossible. For instance, if y = 2 is the smallest, then there's no way to get y = -5. I recommend making a number line.
The only thing left is choice B. If we plug in y = -5 then we get...
y = |x-2| - 6
-5 = |x-2| - 6
-5+6 = |x-2|
|x-2| = 1
x-2 = 1 or x-2 = -1
x = 1+2 or x = -1+2
x = 3 or x = 1
Plugging either of those x values into y = |x-2| - 6 leads to y = -5
You could try solving something like -5 = |x-6| + 2 for x, but you'll find that it has no solutions.
As another alternative, you can graph each answer choice. Then see which one intersects the horizontal line y = -5. You should see that only y = |x-2| - 6 does so.

Step-by-step explanation:
Let x represent the middle one. Then the sum of the first two is ...
(x -1) +x
And we want that to be 3 more than the third:
(x -1) +x = (x +1) +3
2x = x +5 . . . . . . . . . add 1, simplify
x = 5 . . . . . . . . . . . . . subtract x

7) (-7) + (-10) – 5 +2
here, we will use the BODMAS rule, the addition and subtraction will go from left to right.
= -7 -10 -5 + 2
= -17 -5 + 2
= -22 + 2
= -20
8) (-9) + 4 + (-8) – (-7)
= -9 +4 -8 +7
= -5 -8 +7
= -13 + 7
= -6
9) (-6) – (2 x 4) – (-1)
= -6 - 8 +1
= -12 + 1
= -11
10) (-8) + (-4 ÷ -4) – 8
= -8 -4/ (-4) - 8
= -8 +1 -8
= -7 -8
= -15
Therefore, the value of the given expression 7) (-7) + (-10) – 5 +2 is -20, 8) (-9) + 4 + (-8) – (-7) is -6, 9) (-6) – (2 x 4) – (-1) is -11, 10) (-8) + (-4 ÷ -4) – 8 is -15.

8. Dai is comparing how many trading cards he has with his friend Maura. Initially, they find that Dai has four
more cards than twice the number that Maura has.
(a) If the number of cards Maura initially has is represented by n, then write an expression for the number of
cards that Dai initially has.
(b) If Dai must give Maura 8 cards so that they have the same amount, set up and solve an equation to
determine the number of cards Maura initially had.
Answers
Answer:
2n + 4
n = 12
Step-by-step explanation:
Given that :
Initial :
Dai has four more cards than twice the number that Maura has.
Maura's initial card = n
Dai's initial card = 2n + 4
B.)
If Dai must give Maura 8 cards, so they have equal amount
Dai's initial card - 8 = Maura's initial card + 8
2n + 4 - 8 = n + 8
2n - 4 = n + 8
2n - n = 8 + 4
n = 12
A cylindrical syringe has a height of 6.8 cm and a diameter of 2.37 cm is going to be
used to fill a half sphere (semi sphere) with a circumference of 31.4 cm. How many
syringes filled with water would be needed to fill the semi-sphere?
6.8 cm
Answers
Answer:
The number of syringe filled with water that would be needed to fill the semi-sphere is approximately 8.714 syringes
Step-by-step explanation:
The height of the syringe = 6.8 cm
The diameter of the syringe = 2.37 cm
The circumference of the hemisphere = 31.4 cm
Let r represent the radius of the hemisphere, we have;
2·π·r = 31.4 cm
r = 31.4/(2 × π) ≈ 4.9975 cm
The volume of the hemisphere = 2/3 × π × r³ = 2/3 × π × (31.4/(2 × π))³ ≈ 261.4 cm³
The volume of the syringe = π × d²/4 × h = π × 2.37²/4 × 6.8 ≈ 29.998 cm³
The number of syringe filled with water that would be needed to fill the semi-sphere = (The volume of the hemisphere)/(The volume of the syringe)
Therefore;
The number of syringe filled with water that would be needed to fill the semi-sphere = 261.4 cm³/(29.998 cm³) ≈ 8.714 syringes.

X- 2y = 3
3x - y = 2
Answers
Answer: x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
Substitute -7/5 for y in x - 2y = 3:x - 2 (-7/5) = 3x + 14/5 = 3x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)x = 1/5Answer: x = 1/5 and y = -7/5A table showing Number, Value, and Total Value.
