Answer:

1

Step-by-step explanation:

6/8 - 1/2 can be changed to 6/8 - 4/8

This shows us we have 2/8 or 1/4 left

We then turn 3 into 3/1 for the multiplication

3/1 x 1/4 = 3/4

If we change 0.25 into 1/4 we now have 3/4 + 1/4 (or 0.75 + 0.25)

This gives us a solid answer of 1

Sry, I wish I could help. I'm only in high school lol. :(

Domain (value of x) is any real value except x=13orx=−25

Explanation:

Domain is the value of x in the function. Here the denomintor must not be zero. 6x2+13x−5≠0or6x2+15x−2x−5≠0or3x(2x+5)−1(2x+5)≠0or(3x−1)(2x+5)≠0orx≠13andx≠−52∴Domain (value of x) is any real value except x=13orx=−25 [Ans]

Domain (value of x) is any real value except x=13 or x=−25

The domain is the value of x in the function.

Here the denominator must not be zero.

The domain of a function is the set of inputs accepted by the function.

6x^2+13x−5≠0

or 6x^2+15x−2x−5≠0

or   3x(2x+5)−1(2x+5)≠0

or  (3x−1)(2x+5)≠0

or   x≠13  and   x≠−52

∴Domain (value of x) is any real value except x=13 or x=−25.

Divide the percent by 100 to get a decimal number:

Answer:

x = 0 , -2 , 1 +i√3  ; 1 - i√3

Step-by-step explanation:

2x⁴ + 16x = 0

2x(x³ + 8) = 0

2x(x³ + 2³)  = 0

2x (x + 2)(x² -2x + 2²) = 0    {a³ + b³ = (a + b)*(a² -ab +b²}

2x = 0  

x = 0

x + 2 = 0

x = -2

x² - 2x + 4 = 0

a = 1 ; b = -2 and c = 4

D = b² - 4ac = (-2)² - 4*1*4= 4 - 16 = -12

[tex]\sqrt{D} = \sqrt{-12}=\sqrt{2*2*3i^{2}}=2i\sqrt{3}[/tex]

root = (-b ± √D)/2a

= (-(-2) ± 2i√3)/2*1

Answer:

like 1 - y=-5x + 10

line 2 - y=2x + 4

line 3 - y=4x + 3

line 4 - y=8

Step-by-step explanation:

y = mx + b means y equals the slope times x, plus the y intercept, in this case they all had different y intercepts so you just had to look and where the line touches the y axis

Step-by-step explanation:

Answer:

20,000 feet

Step-by-step explanation:

Based on the initial altitude and the rate that the plane is descending, the relevant equation is = 30,000 - 2,000x. The altitude after 5 minutes is 20,000 feet above sea level.

The plane begins at 30,000 feet above ground and is descending at 2,000 feet per minute. The relevant equation after x minutes is:

= Initial altitude - (Descent in feet per minute x Number of minutes)

Plugging in the values gives:

= 30,000 - (2,000 × x)

= 30,000 - 2,000x
