Substitution is when you plug in one value of a variable into an equation. In this case the value of y is given. Plug (x+ 6) into the equation: y=-2x - 3

You should get something like this:
x + 6 = -2x - 3
From there you can add 2x to both sides, and subtract 6 from both sides to get this:
3x = -9
Divide both sides by 3
x = -3
Now that you have the value for x, plug -3 into the equation y = x + 6

y = -3 + 6 = 3

The final answer is D) {-3,3}

*btw in case you didn't know this, the first number in an ordered pair is "x" while the second is "y"

Let y=x+6 be equation 1...
Replace equation 1 in equation 2
X+6 =-2x-3
X+2x = -3 -6
3x = -9
X = -3

Which question should you expect to be answered with variable data?
Valentin [98]

Answer:

The correct answer is the last one.

Step-by-step explanation:

Variable data is any kind of information gathered that can be made into a chart or graph representing what was collected. In other words, the data collected must vary.

The first, second, and third answers cannot be made into a chart/graph as it would be a singular number, and not provide varying data (which is required to produce a graph/chart).

The last answer would be correct as one can create a chart as the data collected from that question would vary. For example, five family members could be born in July, six in August, and ten in October. The variable that is "varying" would be these months.

Hope this helps!

XLiV represents 64 true ya false​
V125BC [204]

Answer:

False

Step-by-step explanation:

Given

XLIV = 64

Required

True or False

The above numeral can be split as follows:

XLIV = XL + IV

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

XL = -10 + 50

XL = 40

In Roman numerals;

IV = 4

Substitute 40 for XL and 4 for IV.

XLIV = 40 + 4

XLIV = 44

Hence;

<em />XLIV = 64<em> is false</em>

Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{100-10}{100}×\frac{100+6}{100}

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{90}{100}×\frac{106}{100}

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax=  $46.746

Hence, the correct answer is $46.746

PLS HURRY AND HELP ME Larry buys peanut butter and bananas at the grocery store. He spends $3.89 on peanut butter and $9.38 in a
Tamiku [17]

Answer:

x = $5.49 cost of the bananas

Step-by-step explanation:

x = cost of the bananas

$3.89 = cost of the peanut butter

$ 9.38 is the cost of both

Bananas + peanut butter = $9.38

    x         +   $3.89           =   $9.38

   <u>             - $ 3.89            =  -$3.89      </u>    Subtract $3.89 from both sides

      x                                 =  $5.49
