Yes, but as you plug whatever numbers you have into the equation parentheses won't be necessary.
Answer:
Step-by-step explanation:
Given function l:
h= -16t² + 26t
where h represents height and t represents time.
The time for dolphin atbthe height 5 feet is given by putting the value of h as 5 in the function,
5 = -16t² + 26t
16t² - 26t + 5 = 0
For this equation: a=16, b=-26, c=5
Use quadratic formula with a=16, b=-26, c=5.
x=(−b±√b2−4ac)/2a
x=−(−26)±√(−26)2−4(16)(5)/2(16)
x=13/16 + 1/16√89 or x=13/16+ −1/16√89
x=1.40 or 0.22

Answer: 6x + 8y =1,245
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each person:
Jack = The total cost (650) must be equal to the product of the number of shirts he bought (2) and the price per shirt (x); plus the product of the number of pair of jeans he bought (5) and the price per jean (y).
2 x+ 5 y=650
Dylan = The total cost (595) must be equal to the product of the number of shirts he bought (4) and the price per shirt (x); plus the product of the number of pair of jeans he bought (3) and the price per jean (y).
4x+3y = 595
Vertical addition:
2 x+ 5 y=650
+
4x+3y = 595
_________
6x + 8y =1,245
Answer:
<h2>y = 7</h2>
Step-by-step explanation:
We know that the sum of the measures of angles on one side of the parallelogram is 180°.
We have the equation:
(6x - 12) + (132 - x) = 180
6x - 12 + 132 - x = 180 <em>combine like terms</em>
(6x - x) + (-12 + 132) = 180
5x + 120 = 180 <em>subtract 120 from both sides</em>
5x = 60 <em>divide both sides by 5</em>
x = 12
Opposite angles in the parallelogram are congruent.
Therefore:
6y + 18 = 6x - 12
Put the value of x to the equation and solve it for y:
6y + 18 = 6(12) - 12
6y + 18 = 72 - 12
6y + 18 = 60 <em>subtract 18 from both sides</em>
6y = 42 <em>divide both sides by 6</em>
y = 7
