X + y = 20 Substitute
x by 2 y - 4 in x + y = 20 to obtain 2 y •
4 + y = 20 Solve for y to find y = 8 and
x = 2y - 4 = 12
Simplifying
2ab + 4ab = 0
Combine like terms: 2ab + 4ab = 6ab
6ab = 0
Solving
6ab = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '6'.
ab = 0
Simplifying
ab = 0
First we write the expressions of each day separately:
Day 1:
you traveled x miles:
x
Day 2:
you drove 58 miles more than 3 times the thousands on Day 1:
3x + 58
Day 3:
your family went 25 fewer thousands than Day 1
x-25
Then, we have:
Day 1 + Day 2 + Day 3:
x + (3x + 58) + (x-25)
Rewriting:
x + 3x + x + 58 - 25
5x + 33
Then, for x = 100
5 * (100) + 33 = 533 miles.
answer:
5x + 33
Total miles that family traveled from home to Disney World is
533 miles
Answer:
y= -4 x+3
Step-by-step explanation: A(1, -1)
the equation is y - y (A)=m*( x-x(A) )
y-(-1)=-4(x-1)
y+1=-4x+4
y= -4x+4-1
y=-4x+3
y=-4x+4-1
