$18.46
Because gerome collected $9.23 and I mult. 2 times and my answer is: $18.46
Answer:
Step-by-step explanation:
Multiply the first equation by 4,and multiply the second equation by 1.
4(x−3y=−6)
1(−4x+9y=9)
Becomes:
4x−12y=−24
−4x+9y=9
Add these equations to eliminate x:
−3y=−15
Then solve−3y=−15for y:
−3y=−15 (Divide both sides by -3)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
x−3y=−6
Substitute5foryinx−3y=−6:
x−(3)(5)=−6
x−15=−6(Simplify both sides of the equation)
x−15+15=−6+15(Add 15 to both sides)
x=9

When you get the answer pls lmk i need that question 2
Answer:
Option 2.
Step-by-step explanation:
It is given that
a = <6,-9,3>
We need to compare the maginitude of vertor a and vector 4a.
If a vector is defined as v = <x,y,z>, then its magnitude is defined as
Using the above formula we get
The vector 4a is
The magnitude of 4a is a factor of 4 greater than the magnitude of a.
Therefore, the correct option is 2.
