Answer:
Step-by-step explanation:
Let the number of hours Nick does the job alone to be x - 3 hours
Hence, in 1 hour, Nick has done 1/x - 3
Together they complete the job in 9 hours
Hence, let's represent the job as 1
9/x + 9/x - 3 = 1
Multiply through by (x)(x-3)
9(x- 3) + 9(x) = 1
9x - 27 + 9x = (x)(x-3)
-27 = x² - 3x
x² - 3x +27 = 0

Answer: A
Step-by-step explanation: If you fill in the x-intercept and the y-intercept and solve -4(2) + 20 = 12 And -4(3) + 20 = 8
if you solve for those you would get your y-intercept
What’s the answer to the question
Answer:
Slope = -2, y-intercept = 12 (b)
Step-by-step explanation:
Using the slope formula:
slope = change in y (y2-y1) / change in x (x2-x1)
slope = (12-18)/(0+3)
slope = -6/3
slope = -2
The slope is -2
If you look in the table, when x=0, the y value equals 12. This means that the y-intercept = 12, since the y-intercept is when the x equals 0. Thus we have our answer.

how do you find the power of the power
Answer:
When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.
Step-by-step explanation:
Complete the table using equivalent ratios.

Determine the intercepts of the line.
x-intercept:( , )
y-intercept:( , )
Answer:
x-intercept: (-7,0)
y-intercept: (0,2)
Step-by-step explanation:
The x-intercept is (-7,0) because on the graph we can see that the line lies on the x-axis on the point (-7,0).
The y-intercept is (0,2) because we can see that the line pass through the y-axis on the (0,2) point.
Hope this helps you :)
Can h help with this?
pleaseee help me answer this
Help me with the questions 1-4, thank you! :)

The weight of an object on Earth varies directly as the weight of the same object on the moon. A 300 pound object on Earth would weigh 48 pounds on the moon. How much would a 75 pound object on Earth weigh on the moon? (Type your number answer. NO LABELS) *
Answer: 12 pounds.
Step-by-step explanation:
To solve this question, we'll use the direct proportion which is.
y = kx
Where,
y = weight on moon = 48 pounds
x = weight on Earth = 300 pounds
k = Unknown
y = kx
48 = 300k
k = 48/300
k = 0.16
The weight that a 75 pound object on Earth would weigh on the moon will be:
y = kx
where,
y = weight on moon = Unknown
k = 0.16
x = weight on Earth = 75 pounds
y = kx
y= 0.16 × 75
y = 12 pounds
The weight on the moon will be 12 pounds.
