-k - 17 = -5 - K - 12
Answers
Answer:
∴ K = 0
Step-by-step explanation:
- K -17 = -5 - K -12
- K + K = - 5 - 12 + 17
0 K = -5 + 5
0 K = 0
∴ K = 0
Answer:
All real numbers are solutions.
Step-by-step explanation:
−k−17=−5−k−12
−k+−17=−5+−k+−12
−k−17=(−k)+(−5+−12)
−k−17=−k+−17
−k−17=−k−17
−k−17+k=−k−17+k
−17=−17
−17+17=−17+17
0=0

16 = -2x - 1
x = -8
x = -7
x = 7
x = 8
Answers
Answer:
x = - 8.
Step-by-step explanation:
Given : 16 = -2x - 1
To find : Solve for x.
Solution : We have given
16 = -2x - 1
On adding both sides by 1
16 + 1 = -2x .
17 = - 2x
On dividing both sides by -2.
x = - 8. 5
If we rounded it it would be - 8 .
Therefore, x = - 8.
I tend to flip so x is on the left, so:
-2x - 1 = 16
-2x = 17
x = -17/2, which is -8.5
Rounding up, your answer would be x = -8 !

To predict how much Zoe would make after 10 hours of work, we set up a proportion using the information given in the question. Cross multiplying and solving for x, we find that Zoe would make $97.50 after 10 hours of work.
Explanation:
To predict how much Zoe would make after 10 hours of work, we can use the information given in the question. We know that after working for 24 hours, Zoe made $234, and after working for 40 hours, Zoe made $390. To find out how much Zoe would make after 10 hours of work, we can use the concept of proportionality. We can set up a proportion using the number of hours worked and the amount earned:
24 hours / $234 = 10 hours / x
Cross multiplying, we get 24x = (10 * $234). Solving for x, we find that x = (10 * $234) / 24. Evaluating the expression, we find that x = $97.50.

Matt bought 7 packages of hot dogs and 5 packages of hamburger.
Step-by-step explanation:
We are given the following in the question
Let x represent the number of packages of hot dogs.
Cost of one packet of hot dog = $2.75
Let y represent the number of packages of hamburgers
Cost of one packet of hamburgers = $3.20
Then, we can write the following equations:
Solving the two equations,
Thus, Matt bought 7 packages of hot dogs and 5 packages of hamburger.

Note: you have not added the image, so I am assuming the quadrilateral MNOP with coordinates M(-4, 0), N(5, -3), P(2, 6) and O(-5, 7). It will anyhow clear your concept as I would explain the concept of reflection over the x-axis.
Step-by-step explanation:
Considering the quadrilateral MNPO with assumed vertices
- M(-4, 0)
- N(5, -3)
- P(2, 6)
- O(-5, 7)
THE RULE OF REFLECTION states that when we tend to reflect a point let say (x, y), across the x-axis, the x-coordinate does not change or transform, but the y-coordinate is changed into its opposite sign i.e. (x,-y).
So, the coordinates of the point in the image after quadrilateral MNPO is reflected over the x-axis will be:
(x, y) (x, -y)
M(-4, 0) M'(-4, 0)
N(5, -3) N'(5, 3)
P(2, 6) P'(2, -6)
O(-5, 7) O'(-5, -7)
Hope, it will help you clear your concept regarding reflection of an object over the x-axis. Using this understanding, you can solve any other question related to this topic.
