9x - y = -2
Part A. To find the solutions that satisfy the equation, find the corresponding values of y for each given value of x.

Part B. Let x = -3, 9(-3) - y = -2
y = -27 + 2 = -25
Let x = 0, 9(0) - y = -2
y = 2
Let x = 3, 9(3) - y = -2
y = 27 + 2 = 29
Therefore, three different solutions are (-3, -25), (0, 2), (3, 29)

Part C. Pairing the equation with 18x - 2y = 5 will result in a system of equations that is inconsistent.

Due to a rise in popularity, Penny's firm begins to make hair bows rather than flower barrettes. She can make hair bows at a rat
Basile [38]

The number of bows that Penny makes per hour and the price the firm sells at shows that the value of the marginal product is $24.95 per hour.

The highest wage the firm will pay is $24.95 per hour.

<h3>What is the value of Penny's marginal product?</h3>

This can be found by the formula:

= Price x Marginal product of Penny

= 4.99 x 5

= $24.95 per hour

The highest wage the firm can pay would be the wage amount that equals their marginal revenue as this is the only way they can maximize profit.

Their marginal revenue in this case is the $24.95 per hour that they pay to Penny so this will be their highest wage to her as well.

Keisha wants to meet for 90 minutes so far she has read 30% of her goal how much longer does she need to read to reach her goal
sladkih [1.3K]

Answer:

30% of 90             

30% x 90              

30/100 =3/10              

3/10 x 90 = 270/10          

270 = 27     

90 - 27 = 63          

Keisha has to read 63 more minutes to reach her goal.

Solve the system of equations.<br> 7x+10y=36<br> y=2x+9<br><br> x = ______<br><br> y = ______
wel

Step-by-step explanation:

Substitute the y in the 1st equation with the 2nd equation.

7x + 10(2x + 9) = 36

7x + 20x + 90 = 36

27x + 90 = 36

3x + 10 = 4

3x = -6

x = -2

So now we can find y.

y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.

So x = -2, y = 5.

David has $9.39 but needs $15.00 to make a purchase. How much more does he need?
elena-14-01-66 [18.8K]

Answer:

$5.61

Step-by-step explanation:

Since David only has $9.39 but he needs $15.00 for his purchase. So, you would subtract the $9.39 from the $15.00 to see how much more money David needs to make this purchase.

15.00 - 9.39

When you carry out this problem, it equals $5.61.

Therefore, David needs $5.61 to be able to complete his purchase
