Answer:
5(2x + 3)
Step-by-step explanation:
We are given with the function that expresses the height of the football over time in the equation <span>h(x) = -16t^2 + 64t. To determine the axis of symmetry, we determine the time when it reaches the maximum height. we derive the equation and equate to zero to get t. -32t +64 = 0. t is equal to 2 seconds. Substituting, to the original equation, h(x) is 64. Hence the axis of symmetry is y = 32. </span>
Answer:
C infinitely many solutions
Step-by-step explanation:
multiply second equation by -3
-3 × (4x + 3y) = -12 ➡ -12x - 9y = 36 now add this to second equation
12x + 9y -12x -9y = -36 + 36 ➡0 = 0
we say there's infinite solutions because whatever value you write for x and/or y there will be a solution.
Answer:
1
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+1=−x+4
Step 1: Add x to both sides.
2x+1+x=−x+4+x
3x+1=4
Step 2: Subtract 1 from both sides.
3x+1−1=4−1
3x=3
Step 3: Divide both sides by 3.
3x
3
=
