Step-by-step explanation:
Answer:he would require 8.33 gallons of gas
Step-by-step explanation:
Mr Dow lives 16 miles from his workplace he drives to and from work five days a week. It means that the distance that he drives everyday to and from work would be
16 × 2 = 32 miles.
Then, the total distance that he drives in a week to and from work would be
32 × 5 = 160 miles
if his car gets 19.2 miles per gallon, it means that the amount of gas that he would use in one week, commuting to and from work would be
160/19.2 = 8.33 gallons
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2

<h3>
<u>Explanation</u></h3>
- Given the system of equations.

- Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.
To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.

There as we can get rid of the y-term by adding both equations.

Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.

Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
- Answer Check by substituting both x and y values in both equations.
<u>First</u><u> </u><u>Equation</u>

<u>Second</u><u> </u><u>Equation</u>

Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
