Answer:
A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.
Step-by-step explanation:
Given
Required
A good first step
A good first step is to eliminate x and this is done as follows:
Multiply by 2 (gotten from coefficient of x in the second equation)
Multiply by 3 (gotten from coefficient of x in the first equation)
This gives:
Add both equations
<em>Hence (a), is true</em>
Answer: D. a rotation followed by a translation
Answer:
D
Step-by-step explanation:
The absolute value function always returns a positive value, that is
| - a | = | a | = a
Given
8 - | 2g - 5 | ← substitute g = - 3.5 into the expression
= 8 - | - 7 - 5 |
= 8 - | - 12 |
= 8 - 12
= - 4 → D
