alina1380 [7]

Answer:

1.25x+2.5y -15 = 0

Step-by-step explanation:

Total amount to be spent on Redbix movies and games = $15

Money to be paid for each movie = $1.25

Money to be paid for each game = $2.50

To find:

Equation in standard form that can be used to graph the line.

Solution:

First of all, let us learn about the standard form of equation of a line.

Standard form can be represented as:

Ax+By+C =0

Where A,B, C are constants.

Now, let us try to make equation.

Let number of movies bought = x

Amount to be paid for movies = $1.25x

Let number of movies bought = y

Amount to be paid for movies = $2.50y

Total money is $15.

Therefore, we can write the equation as:

1.25x+2.5y = 15

Standard form can be written as:

1.25x+2.5y -15 = 0

Yer has 2107 beads for making jewelry. If each necklace she makes needs 49 beads, how
9966 [12]

41 necklaces can be made using 2017 beads where 49 beads are used to make 1 necklace.

The total number of beads for making jewelry with Yer = 2017

Beads require to make 1 necklace = 49 beads

The number of necklaces that can be made using 2017 beads when 49 beads are required to make 1 necklace will be:

Number of necklace = 2017 / 49

Number of necklace = 41.16

That is 41 necklaces can be made using 2017 beads where 49 beads are used to make 1 necklace.

Therefore, 41 necklaces can be made using 2017 beads where 49 beads are used to make 1 necklace.

Solve for x: 2(x + 3)2 − 4 = 0
asambeis [7]

Answer:

Option D) x = −4.41, −1.59

Step-by-step explanation:

We are given the following expression in the question:

2(x + 3)^2 - 4 = 0

Solving the above expression, we get:

2(x + 3)^2 - 4 = 0\\2(x^2+9+6x)-4=0\\\text{Identity: }(a+b)^2 = a^2 + b^2 + 2ab\\2x^2+18+12x-4=0\\2x^2+12x+14=0\\\text{Using the quadratic formula:}\\ax^2 + bx +_ c = 0\\\\x = \displaystyle\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\text{Puting a = 2, b = 12, c = 14}\\\\x = \displaystyle\frac{-12\pm \sqrt{(12)^2-4(2)(14)}}{2(2)}\\\\x = \frac{-12 \pm 5.65}{4}\\\\x = \frac{-12 + 5.65}{4}, \frac{-12-5.65}{4} = -1.5875, -4.4125 \approx -1.59, -4.14
