It's a linear function. We need only two points to draw a graph.
We choose any values of x and calculate the value of y.
for x= 0 → y = 3(0) - 1 = 0 - 1 = -1 → (0, -1)
for x = 2 → y = 3(2) - 1 = 6 - 1 = 5 → (2, 5)
for x = 0 → y = 3(0) - 1/3 = 0 - 1/3 = -1/3 → (0, -1/3)
for x = 2 → y = 3(2) - 1/3 = 6 - 1/3 = 5 2/3 → (2, 5 2/3)
Answer:
$63
Step-by-step explanation:
<em>I believe you meant Richard worked for 7 </em><em>hours</em> and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to <u><em>multiply Richard's salary rate with his number of working hours.</em></u>
- 7 hours x 9 dollars/hour = $63
Therefore, Richard earned $63 for his 7-hour work.
<u>Additional Information</u>
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
- 10 hours x 9 dollars/hour = $90
Answer:
1
Step-by-step explanation:
9 - 4 x 2
4 x 2 = 8
9 - 8 = 1
Multiply in order
-8 * -8 = 64
64 * 5 = 320
320 * 5 = 1600
1600 * -8 = -12800
-12800 is your answer
You need to categorize the similar terms with the same exponential.
Here, 3 terms can be categorized: x^3, x^2 and constant
Then you simply manipulate the coefficient:
(5-9)x^3 + (-7+4)x^2 + (6+1) = -4x^3 - 3x^2 + 7
