Answer:
Option C. Step 3
Step-by-step explanation:
step 1
Identify the pre-image and the image: The pre-image is triangle XYZ, and the image is X'Y'Z'
The step 1 is correct
step 2
Identify the number of units that each point moves horizontally: Each point moves one unit left.
The step 2 is correct
step 3
Identify the number of units that each point moves vertically: Each point moves three units down
<u>The step 3 is not correct</u>
Each point moves three units up
step 4
The translation is one unit left and three units down
<u>the step 4 is not correct</u>
The translation is one unit left and three units up
therefore
The first error is in the Step 3
Answer:
x = 2 and y = 1
Step-by-step explanation:
First, solve for y by substituting the second equation as x into the first equation
-2x - 3y = -7
-2(y + 1) - 3y = -7
Simplify and solve for y
-2y - 2 - 3y = -7
-5y - 2 = -7
-5y = -5
y = 1
Solve for x by plugging in 1 into the second equation
y + 1 = x
1 + 1 = x
2 = x
So, the answer is x = 2 and y = 1
<u>Answer:</u>
The correct answer option is D. 5.
<u>Step-by-step explanation:</u>
We are given the following expression where 4 is to be divided by a fraction 1/5:
÷ 
This can also be written as:

Now to find the quotient of this, we will take the reciprocal of the fraction in the denominator to change it into multiplication.

Therefore, ignoring the 1 in denominator, we can simply multiply 4 by 5.

Answer: True</h3>
Explanation:
This theorem doesn't have a name unfortunately. So searching it out is a bit tricky if you don't know the right way to word things. Luckily it wasn't too hard of a find, and I managed to track it down in a linear algebra textbook.
Check out the screenshot below for the snippet of the theorem and the corresponding proof. The book simply refers to it as "theorem 1.9", which again, is an unfortunate choice of naming.
