Answer:
X=1
Step-by-step explanation:
help, please!!!!!!!!!
Help me with the questions 1-4, thank you! :)
Answer:
1) Slope is 2/1 and the y-intercept is 2 --> y = 2x+ 2
2) Slope is -1/3 and the y-intercept is -3 --> y = -1/3x -3
The images for question 3 and 4 are below:
The equations for
3) y = 1/3x - 5
4) y = -2x-8
Step-by-step explanation:
4. Find the slope of the line through the
points A(8,7) and B(5,-2).
Explanation:
Answer:
Slope equals to 3
Step-by-step explanation:
-2-7=-9 over 5-8=-3. You then divide the 9 by 3 and because they are both negative they equal a positive.
Determine A:B:C, if A:B= 2:3 and B:C =4: 5
Is this a function? Can you show your work on how you got the answer plz?
Answer:
yes it is a function because the x does not repeat itself

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 :)

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.

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.
