5 0

Answer:

please see explanation

Step-by-step explanation:

10a {}^{2}  + 4 =  - 186 \\ 10a {}^{2}  =  - 186 - 4 \\ 10a {}^{2}  =  - 190 \\ divide \: bothsides \: by \: 10 \\  \frac{10a {}^{2} }{10}  =   \frac{ - 190}{10}  \\ a { }^{2}  =  - 19 \\ square \: root \: bothsides \\    \sqrt{a {}^{2} }  =    \sqrt{ - 19}   \\ a =  - 1 \sqrt{19 }  \\ a =   + i \sqrt{19}  \: or \: a =  - i \sqrt{19}

Which equation represents the line that passes through the points (2, 4) and (1, -3)?
zhannawk [14.2K]

Answer:

y = 7x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (1, - 3)

m = \frac{-3-4}{1-2} = \frac{-7}{-1} = 7, thus

y = 7x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 4), then

4 = 14 + c ⇒ c = 4 - 14 = - 10

y = 7x - 10 ← equation of line

Suppose one bag contains 500 cubic inches of confetti. How many bags will Student Government need to fill 100 containers? If the
Vanyuwa [196]

The number of bags that they will need if each bag contains 500 cubic inches of confetti is 20,000

<h3>How to find the total volume ?</h3>

One bag contains 500 cubic inches of confetti.

Therefore,

1 bag = 500 inches³

The student need to fill 100 containers with the bag.

Each container can accomodates 100,000 cubic inches.

Therefore,

1 bag = 500 inches³

100,000inches³ = 1 container = 200 bags

Therefore,  

100 containers will contain 20, 000 bags of confetti.

Laura is planning a party for her son. She has $50 dollars remaining in her budget and wants to provide one party favor per pers
enyata [817]

Answer:

The system of inequalities that represents this situation is:

x+y≥10

6x+4y≤50

Step-by-step explanation:

As the statement says that Laura wants to provide one party favor per person to at least 10 guests, the first inequality would indicate that the number of stuffed animals plus the number of toy trucks should be equal or greater than 10:

x+y≥10

Also, the statement indicates that miniature stuffed animals cost $6.00 each and the toy trucks cost $4.00 each and that Laura has $50. From this, you would have an inequality that indicates that 6 for the number of miniature stuffed animals and 4 for the number of toy trucks would be equal or less than 50:

6x+4y≤50

The answer is that the system of inequalities that represents this situation is:

x+y≥10

6x+4y≤50

How do you simplify 7 (2x+10) thanks in advance
kramer
The only thing you should do is to multiply 7 by 2x and 10. 
so you will have: (7*2x) + (7*10) = 14x + 70 :)))
i hope this is helpful 
have a nice day
