What number should be added to 2/8 to -1/12 get ?​

Answer:

k = [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

Using the discriminant

Δ = b² - 4ac

For a repeated real solution then

b² - 4ac = 0

Given

16x² - [tex]\frac{8}{3}[/tex] x + k = 0

with a = 16, b = - [tex]\frac{8}{3}[/tex] , c = k

(- [tex]\frac{8}{3}[/tex] )² - ( 4 × 16 × k) = 0

[tex]\frac{64}{9}[/tex] - 64k = 0 ( subtract [tex]\frac{64}{9}[/tex] from both sides )

- 64k = - [tex]\frac{64}{9}[/tex] ( divide both sides by - 64 )

k = [tex]\frac{1}{9}[/tex]

Answer:

23/20

Step-by-step explanation:

Find the common denominator of the 2 fractions (It's 20):

3/4 + 2/5            

Multiply both numerator and denominator by 5 for the first fraction and multiply by 4 for the second fraction:    

15/20 + 8/20        

Add the fractions together:

23/20

Answer:

the answer is 28

Step-by-step explanation:

PEMDAS:

(8-2) = 6

6^2= 36

36/2= 18

18+10= 28

Answer:

D. 28

PEMDAS:

Parenthesis, exponents, multiplication, division, addition, subtraction

10 + (8 - 2)^2 / 2

1. Parenthesis comes first so we're left with

10 + (6)^2 / 2

2. Then we do the exponents

10 + 36 / 2

3. Then it's division

10 + 18

4. Finally we add

Answer:

AC = 15

Step-by-step explanation:

AC is the entire line split into two segments; AB and BC

We are given that AB = 8 and BC = 2x + 25 so we can combine these two and set them equal to AC ( = x + 24)

x + 24 = 8 + 2x + 25

Combine like terms and isolate x

x + 24 = 2x + 33

-9 = x

Now plug in -9 for x in the equation for line AC

(-9) + 24 = 15

Step-by-step explanation:

The parallel line will have an equation of the form

[tex]y = -\dfrac{1}{2}x + b[/tex]

We solve for b by plugging in the values of the point (3, -4):

[tex]-4 = -\dfrac{1}{2}(3) + b[/tex]

[tex]\Rightarrow -8 = -3 + 2b[/tex]

Solving for b, we get

[tex]b = -\dfrac{5}{2}[/tex]

Therefore, the equation of the line parallel to 2x + 4y = 10 is

[tex]y = -\dfrac{1}{2}x -\dfrac{5}{2}[/tex]

In standard form we can write

[tex]x + 2y = -5[/tex] or [tex]2x + 4y = -10[/tex]

Answer:

Answer: 9 sweets/friend

Step-by-step explanation:

s = Number of sweets per friend

n = Number of sweets in a box = 54

f = Number of friends = 6

formula for the number of sweets each friend gets is as follows:

                                n/f = s

Therefore substituting in formula for n=54 and f=6

                                  54/6 = 9 sweets per friend

Answer:

Equation is 3y = x + 19

Step-by-step explanation:

General equation:

[tex]y = mx + c[/tex]

For slope, m:

[tex]m_{1} \times m_{2} = - 1[/tex]

but m1 is -3:

[tex] - 3m_{2} = - 1 \\ m_{2} = \frac{1}{3} [/tex]

For y-intercept, c:

[tex]y = mx + c \\ 6 = ( - 1 \times \frac{1}{3} ) + c \\ \\ c = 6 + \frac{1}{3} \\ \\ c = \frac{19}{3} [/tex]

equation:

[tex]{ \sf{y = \frac{1}{3}x + \frac{19}{3} }} \\ \\ 3y = x + 19[/tex]

Answer:

A: y = 17x

Step-by-step explanation:

Answer:

21 is A

22 is B

Step-by-step explanation:

51 / 3 = 17, which is the cost of 1 hour.  That means, in order to find the charge (y), you need to multiply the # of hours (x) by 17.  Equation A represents this correctly.  

Now that we know this, for question 22, if someone rented a machine for 3.5 hours, to find the charge, multiply 3.5 by 17.  This gives you 59.50.

Answer:

16/25

Step-by-step explanation:

(5/4)^-2 = (4/5)^2 = 16/25

The given expression (5/4)⁻² is equivalent to 16/25.

To rewrite (5/4)⁻² without an exponent, we can apply the reciprocal property of exponents.

The reciprocal of (5/4)⁻² is equal to the reciprocal of 5/4 raised to the power of 2.

The reciprocal of a fraction is obtained by flipping the numerator and denominator.

So, the reciprocal of 5/4 is 4/5.

Now, we raise the reciprocal (4/5) to the power of 2.

To do this, we multiply the numerator and denominator of 4/5 by itself.

(4/5)² = (44) / (55) = 16/25

Therefore, (5/4)⁻² can be rewritten as 16/25 without an exponent.
