Y=1/3x+c as 1/3 is the gradient/slope
Plug in the coordinates into the equation
-2= 1/3*(1) +c
C=-2-1/3
C=-7/3
Y= 1/3x-7/3
Answer:
C f=9
Step-by-step explanation:
isolate f on one side so you subtract 5 from both sides to get 3f=27 and then divide by 3 on each side to get f=9
Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24
Answer:
C
Step-by-step explanation:
<u>Equation A</u>
16x - 7 = 11x - 32
(16x - 7) - 11x = (11x - 32) -11x
5x - 7 = -32
(5x - 7) + 7 = (-32) + 7
5x = -25
(5x)/5 = (-25)/5
x = -5
<u>Equation B</u>
-4x - 10 = 2x + 20
(-4x - 10) - 2x = (2x + 20) - 2x
-6x - 10 = 20
(-6x - 10) + 10 = (20) + 10
-6x = 30
(-6x)/-6 = (30)/-6
x = -5
Both Equation A and Equation B have a solution of -5.
Answer:
The number of pipes to be cut from total length of pipe is 10 pipes
Step-by-step explanation:
Given as :
Total length of pipe = l = 7
foot
i.e ' = 
foot
The length of pipe to be cut = l' = 
foot
Let The number of pipes to be cut = n pipes
<u>According to question</u>
The number of pipes to be cut = 
i.e n = 
Or, n = 
Or, n = 
or, n = 5 × 2
∴ n = 10 pipes
So, The number of pipes to be cut = n = 10 pipes
Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
