Create an equation that matches this table
Radda [10]

The equation that matches the given table is

y = 10x + 40

Solution:

General equation of a line : y = mx + c

Let us find the equation of the table.

<u>Common differences of X: </u>

0 – 1 = 1, 1 – 2 = 1, 3 – 2 = 1, 4 – 3 = 1, 5 – 4 = 1

<u>Common differences of Y: </u>

50 – 40 = 10, 60 – 50 = 10, 70 – 60 = 10, 80 – 70 = 10, 90 – 80 = 10

$m=\frac{\Delta y}{\Delta x}

$m=\frac{10}{1}

m = 10

Substitute m = 10 in general equation of a line

y = 10x + c

To find the constant term, substitute x = 0 and y = 40.

40 = 10(0) + c

40 = 0 + c

40 = c

c = 40

Therefore the equation of a line is y = 10x + 40.

Hence the equation that matches the given table is y = 10x + 40.

Alang went to the store to buy some walnuts. The price per pound of the walnuts is $7 per pound and he has a coupon for $2.50 of
MA_775_DIABLO [31]

Answer:

$11.50 is the cost for 2 pounds of walnuts

Expression: 7p - 2.50

Step-by-step explanation:

First, create an expression to represent the cost:

7p will represent the cost, since the walnuts are $7 per pound, and 2.50 needs to be subtracted from this because of the coupon for $2.50 off

So, the expression is 7p - 2.50

Use this expression to find the price for 2 pounds of walnuts:

7p - 2.50

7(2) - 2.50

14 - 2.50

= 11.50

So, the cost with the coupon will be $11.50

Solve –2 + x &gt; 10 using the properties of inequalities.
lys-0071 [83]
Using the properties of inequalities:
Subtract -2 from each side of the inequality    -2 + x > 10
Remember -2 - -2 becomes -2 + 2 = 0          <u>- -2 + x > --2
</u>10 - -2 becomes 10 + 2 =12<u />                             0 + x > 12
So the final solution would be x > 12.
Therefore x would have to be all numbers greater than 12.
