The lowest point on the parabola is (0, -1).
astraxan [27]

Answer:

vertex

Step-by-step explanation:

vertex

If the coefficient a > 0, then the parabola opens upward and the vertex is the lowest point on the parabola. We say that k is the minimum value of the quadratic function. On the other hand, if the coefficient a < 0, then the parabola opens downward and the vertex is the highest point on the parabola.

The denominator of a rational numbers is twice it’s numerator if the numerator is decreased by 3 and the denominator increased b
ASHA 777 [7]

Answer:

\frac{29}{58}

Step-by-step explanation:

let x be the numerator of the rational number then 2x is the denominator

original fraction = \frac{x}{2x}

subtracting 3 from numerator and adding 7 to denominator , gives

\frac{x-3}{2x+7} = \frac{2}{5} ( cross- multiply )

5(x - 3) = 2(2x + 7) ← distribute parenthesis on both sides )

5x - 15 = 4x + 14 ( subtract 4x from both sides )

x - 15 = 14 ( add 15 to both sides )

x = 29

rational number = \frac{29}{58}

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Jordan play
stiv31 [10]
Okay so for each person we're pretty much gonna have to find the value of strokes over holes.
Rory: 42 strokes per 9 holes
Jordan: 79 strokes per 18 holes
Ricky: 123 strokes per 27 holes

Now, we can do the division for each person and round. But first, I'll say stokes per hole is s/h. Just feed each number into a calculator like this: <em>per </em>means divide.

Rory: 4.66667 s/h
Jordan: 4.38889 s/h
Ricky: 4.55556 s/h
Well, Jordan had the lowest number of strokes per hole since his value is the smallest.

Answer: Jordan

The length of the top of a table is 55 m greater than the width. the area is 8484 msquared2. find the dimensions of the table.
Oksana_A [137]
You have to do similar calculations you use in algebra. This is how I get the answer;
First I draw out the algebraic formula 55m • X = 8,484 m (meters) 2 (squared). Then I switch the sign from multiplication to division and switch put numbers 55 and 8,484 in different places and change it to your new formula 8,484/(divided) 55 =X. Then you do the math of 8,484 divided by 55 and get an answer of 154.254545. But you can just leave it at the first 2 digits on the right side of the decimal by rounding 4 down and leaving it at an answer of ~~(<This is your answer after being put together with these tips (you always right your final answer using your formula and plugging in the number that we got from dividing 8,484 by 55;

Final answer ( if they wanted it included in a formula); 8,484/55=X let X=~~154.25

Final answer (if they wanted it as one final number as you answer); ~~154.25

*Hope these tips helped you with this mathematical problem :)

Find a number halfway between 2 1/2 and 1 1/3
kvasek [131]

Answer:

23/12

Step-by-step explanation:

2 1/2 = 5/2(3/3) = 15/6

1 1/3 = 4/3(2/2) = 8/6

15/6 - 8/6 = 7/6

7/6(1/2) = 7/12

16/12 + 7/12 = 23/12
