3x + 2y = -26
4x - 5y = -4
To eliminate, we are going to cancel out the y
So multiply the first equation by 2.5, and you'll get
7.5x + 5y = -65
Add this equation to the second, and you'll get
11.5x = -69
Divide by 11.5 on both sides, and you get
x = -6
Now plug the -6 into the first equation, and you get
3(-6) + 2y = -26
Solve
-18 + 2y = -26
2y = -8
y = -4
Step-by-step explanation:
you multiply 1/6 to each number in the brackets
Answer:
Moves it up 5 units
Step-by-step explanation:
The +5 outside of any parenthesis on a graph moves it up.
Answer:
Step-by-step explanation:
Let's solve for f.
y=3x−2x2findf(3)
Step 1: Flip the equation.
−6df2inx2+3x=y
Step 2: Add -3x to both sides.
−6df2inx2+3x+−3x=y+−3x
−6df2inx2=−3x+y
Step 3: Divide both sides by -6dinx^2.
−6df2inx2
−6dinx2
=
−3x+y
−6dinx2
f2=
3x−y
6dinx2
Step 4: Take square root.
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
Answer:
f=√
3x−y
6dinx2
or f=−√
3x−y
6dinx2
551, it is too big of a number so it is the outlier. :)
