Answer:
The answer is y = 7/x -6.
Step-by-step explanation:
A linear function is one where x and y are both to the first power. Using this knowledge, let's look at the options that we are given.
y = 4x + 9
In the above equation, both x and y are raised to the first power, so we know that this equation is linear.
y = 7/x - 6
In the above equation, y is raised to the first power, but x is not. Since x is in the denominator of a fraction, it actually has a power of -1, which makes this equation nonlinear.
y = x - 6/7
In the above equation, both x and y are raised to the first power, making the equation linear.
Therefore, the correct choice is y =7/x - 6.
Hope this helps!
Answer:
3x=42
Step-by-step explanation:
assume Jay works x hours in daycare, which means he works 2x hours in the grocery store, he totally works 42 hours per week equal to x hours in daycare plus 2x in the grocery store.
I'm assuming that the 3434 is a typo error. It should be 34.
Marni: 18 + 0.80m
Sharika: 12 + 0.9m
x = Sharika's minutes
x + 34 = Marni's minutes
[18 + 0.80(x+34)] + [12 + 0.90(x)] = 264
18 + 0.80x + 27.2 + 12 + 0.90x = 264
0.80x + 0.90x = 264 - 18 - 27.2 - 12
1.70x = 206.80
x = 206.80/1.70
x = 121.65 or 122
x + 34 = 122 + 34 = 156 minutes.
The sum of two numbers is 20 and their difference is 4. Which is the greater of the two numbers? The answer is 12.
slope of line=(y2-y1)/(x2-x1)
give is
(x1,y1)=(8,2)
(x2,y2)=(10,2)
therefore slope =(2-2)/(10-8)=0/2=0
Hence
answer
Slope of line=0
