Answer:
In geometry, a transformation is an operation that moves, flips, or changes a shape (called the preimage) to create a
new shape (called the image). A translation is a type of transformation that moves each point in a figure the same
distance in the same direction. Translations are often referred to as slides. You can describe a translation using words
like "moved up 3 and over 5 to the left" or with notation. There are two types of notation to know.
1. One notation looks like T(3, 5). This notation tells you to add 3 to the x values and add 5 to the y values.
2. The second notation is a mapping rule of the form (x, y) → (x−7, y+5). This notation tells you that the x and
y coordinates are translated to x−7 and y+5.
Step-by-step explanation:
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Answer:
A.) 194,538
Step-by-step explanation:
the value of 5 in the number 95,126 is equal to 5,000. 1/10 of the value 5,000 is 500 (500 x 10 = 5,000). the value that the 5 is at in the number 194,538 is the hundreds place, so the calue is equal to 500, 1/10 of 5,000.
The answer to 5 is A. And the answer to #6 is B. Here is why: So the cost for 6 pens is $2.34. So, you want to find the unit rate. The unit rate basically, in this case, would be how much on pen costs. So to find how much one pen costs you would divide 6 into $2.34. That would give you .39¢. Now to find out how much 20 pencils would cost you would multiply .39¢ by 20. This would give you $7.80. Do you see it now? I hope this could be helpful!
