I would love for someone to help me with this.
scoray [572]

Answer:

5x + 3y = 12

Step-by-step explanation:

We are given the line 5x + 3y = 6 and are to find the equation of a new line that is parallel to this one and goes through (3, -1).

Parallel lines have the same slope.  The slope of the given line is determined by the coefficients 5 and 3 visible above.  Therefore, the form of the equation of the new line is 5x + 3y = C, where we must determine the value of C.

Substitute 3 for x and -1 for y in 5x + 3y = C, obtaining:  5(3) + 3(-1) = C.  Then 15 - 3 = 12 is the constant value, and the equation of the 'new line' is

5x + 3y = 12

Answer:

<u>The correct answer is 15 1/2 inches</u>

Correct graph:

Adding it below from previous question that can be found at brainly

Step-by-step explanation:

As we can see in the line plot below, we have:

  • 3 * 1/2 = 1.5
  • 5 * 1 = 5
  • 6 * 1 1/2 = 9

Now, adding up we have:

1.5 + 5 + 9 = 15.5 or 15 1/2 inches

A jewelry store has 311.75 ounces of 14-carat gold in stock.
WARRIOR [948]

Answer:

\boxed{\text{(a) 86 necklaces; (b) \$2220}}

Step-by-step explanation:

(a) Number of necklaces

3⁵/₈ = 3.625

\text{No. of necklaces} = 311.75\text{ oz} \times \dfrac{\text{1 necklace}}{3.625\text{ oz}} = \textbf{ 86 necklaces}\\\\\text{You can make } \boxed{\textbf{86 necklaces}} \text{ from 311.75 oz of 14K gold}

(b) Value of gold in each necklace

There are 3.625 oz of 14K gold in each necklace. Pure gold is 24K.

\text{Mass of pure gold} = \text{3.625 oz} \times \dfrac{\text{14K}}{\text{24K}} = \text{2.1146 oz}

Pure 24K gold is worth $1050/oz.

\text{Value of pure gold} = \text{2.1146 oz} \times \dfrac{\text{\$1050}}{\text{1 oz}} = \textbf{\$2220}\\\\\text{The value of the gold in each necklace is } \boxed{\textbf{\$2220}}
