Answer:
The function was expanded vertically by 5, and then translated vertically upwards 6 units.
Which is the third option in the list of possible answers.
Step-by-step explanation:
Recall that the types of transformations associated with:
A) a function multiplied by a positive factor larger than one consists on the function expanded vertically by that factor.;
B) a positive number added to the function consists on the vertical translation of the function upwards as many units as the number added.
Therefore, the function being transformed into
consists of the initial function expanded vertically by 5, and then translated vertically upwards 6 units.
<u>Answer:</u>
- x = -5
- y = 5
<u>Step-by-step explanation:</u>
- => -7x - 2y = 25
-4x - 9y = -25
- => 4(-7x - 2y = 25)
7(-4x - 9y = -25)
- => -28x - 8y = 100
-28x - 63y = -175
- => 55y = 275
- => y = 5
<u>Now, let's substitute the value of y into the first equation.</u>
- => -7x - 2y = 25
- => -7x - 2(5) = 25
- => -7x - 10 = 25
- => -7x = 35
- => x = -5
<u>Now, let's check our answer to make sure our answer is correct.</u>
<u>Check:</u>
- -4x - 9y = -25
- => -4(-5) - 9(5) = -25
- => 20 - 45 = -25
- => -25 = -25
Hence, this is proved correct.
Hoped this helped.
