Answer:
x=-7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x−4=3+8x
7x+−4=3+8x
7x−4=8x+3
Step 2: Subtract 8x from both sides.
7x−4−8x=8x+3−8x
−x−4=3
Step 3: Add 4 to both sides.
−x−4+4=3+4
−x=7
Step 4: Divide both sides by -1.
−x/−1=7/−1
x=−7

Step-by-step explanation:
Hello
please find attached the graph
you can notice that 
(a) from the graph we can say that there is no maximum and one minimum in x = 3
and then f(3) = 0 so o is the minimum of f
(b) vertex is (3,0)
(c) x = 3 is an axis of symmetry
(d) as the root is 3
(e) y=9 for x = 0 so the y-intercept is 9

For the first plan, we can write it as 57+0.11m if m represents the miles driven due to that we have a base value of 57 but add $0.11 per mile . Similarly, for the second plan we can write 50+0.13m. Since we want them to be equal, we have 57+0.11m=50+0.13m. Subtracting 0.11m as well as 50 from both sides, we get 0.02m=7. Next, we can multiply both sides by 50 to get 350=the amount of miles needed for them to be the same. For the cost, we can plug 350 into either expression to get 57+0.11*350=95.5 dollars
Answer:
solid and liquid
Step-by-step explanation:
So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
