Answer:
7
Step-by-step explanation:
The formula would be c=(320/x)+3
C is the total chairs and x is the price per chair and we add 3 since she is getting 3 for free
Following PEMDAS, we should do 320/80 first which is 4
Then the equation becomes 4+3=7
Answer:
v= 2.66 m/sec
Step-by-step explanation:
supposing we have to find their speed just as he grabs her.
Applying law of conservation of Energy
That is
p_i= p_f
Initial momentum = p_i = 35×0+ 44×4.9= 210.6 kg.m/sec.
final momentum p_f= (35+44)v
let the final velocity of combined body be v
therefore,
79v= 210.6
v= 2.66 m/sec.
Answer:
slope of y = -7 is 0
Step-by-step explanation:
y = any number forms a graph of a horizontal line
x = any number forms a graph of a vertical line
For any horizontal line , the slope is always 0
for any vertical line , the graph is always undefined
So for y =-7 we will get a horizontal line at -7 on t
the slope of horizontal line y=-7 is 0
Answer:
Y = 9 + 2/3
Step-by-step explanation:
First, find the equation for the given points ((0, - 4) and (3, 2)). By graphing these points, I found that this equation was Y = -4 + 2/3.
Now, we can start to form the equation of the line you are trying to find. Because parallel lines must have the same slope, we know that the slope of the line will be 2/3. We can now use this slope to find the Y-intercept of the line. Add 2 to the X-coordinate and 3 to the Y-coordinate. By doing this you get the coordinates (0, 9). 9 is the slope of the second line.
Now we can make the equation you are trying to find. The answer is Y = 9 + 2/3 where 9 represents the Y-intercept and 2/3 represents the slope of the line.
Hope this helps! Let me know.
Answer:

Step-by-step explanation:
Each y is 3 times the last one, so it's geometric, so exponential. 3 should appear as the base.
