<u>Answer</u>:
b = 4a
<u>Step-by-step explanation</u>:
<em>changing sides changes sign division to multiplication.</em>
-5x - 7 < 28.....add 7 to both sides
-5x < 35....divide both sides by -5, change the inequality sign (u change the inequality sign when dividing/multiplying by a negative number)
x > -7
{\text{Direction of parabola depends on the sign of quadratic coefficient of a }} \hfill \\
{\text{quadratic equation}}. \hfill \\
{\text{For given quadratic equation}}. \hfill \\
a{x^2} + bx + c = 0 \hfill \\
{\text{The parabola is in the upward direction if }}a{\text{ }} > {\text{ }}0{\text{ and in downward direction if }}a < 0 \hfill \\
{\text{Here, the equation of given parabola is }} \hfill \\
{x^2} - 6x + 8 = y \hfill \\
\Rightarrow y = \left( {{x^2} - 6x + 9} \right) - 9 + 8 \hfill \\
\Rightarrow y = {\left( {x - 3} \right)^2} - 1. \hfill \\
{\text{Thus, the parabola is in the upward direction}} \hfill \\
Answer:
It would take Jared 2 hours to finish mowing 3 acres at that rate.
Step-by-step explanation:
If it takes Jared 1 hour to mow 1 and 1/2 acres of lawn and he has to mow three, then 1 1/2 acres x2= 3 acres and 1 x2= 2 so it would take Jared 2 Hours to mow 3 acres of Lawn
