Written in standard form, when will a quadratic equation have a local maximum?

1 answer:

8 0

Answer:

If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum. For example, if you have the function 2x^2+3x-5, the function has a minimum because the x^2 coefficient, 2, is positive.

Josh is hiking Glacier National Park. He has now hiked a total of 17 km and is 2 km short of being half of the way done with thi

poizon [28]

Hello!

What we know so far is that Josh has hiked 17km. He is 2km short of being half way done with the hike.

To solve this, we must add 17 and 2 (to find the kilometers that he has hiked and the kilometers that he needs to hike to reach half way.)
17+2= 19

Now we know that 19km is exactly halfway in Josh's hike.
To find the total amount of km in Josh's hike, we must multiply 19 by two. (Half way times two = total amount)

19x2= 38

The total amount of kilometers in Josh's hike is 38km.

I hope this helps you!!

Answer:

x=4

Step-by-step explanation:

In a equilateral triangle, every angle has a measure of:

$\frac{180}{3} = 60$

so:

$10x + 20 = 60 \\ 10x = 40 \\ x = 4$

Linear System, substitutional method 5x+4y=32 9x-y=33 helppp

Pachacha [2.7K]

5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ 45x - 5y = 165
 41y = 123
 41 41
 y = 3
 5x + 4(3) = 32
 5x + 12 = 32
 - 12 - 12
 5x = 20
 5 5
 x = 4
 (x, y) = (4, 3)
