Answer:
1/3, 1, 3/25, 1/2, 36/49
Step-by-step explanation:
When dividing fractions you flip the second fraction and multiply across
Answer:
(x - y)(x - y + a)
Step-by-step explanation:
![(x-y)^2-a(y-x) \\ \\ = (x-y)^2 + a(x - y) \\ \\ = (x - y) \{(x - y) + a \} \\ \\ = (x - y)(x - y + a)](https://tex.z-dn.net/?f=%28x-y%29%5E2-a%28y-x%29%20%5C%5C%20%20%5C%5C%20%20%3D%20%28x-y%29%5E2%20%2B%20a%28x%20-%20y%29%20%5C%5C%20%20%5C%5C%20%3D%20%20%28x%20-%20y%29%20%5C%7B%28x%20-%20y%29%20%2B%20a%20%5C%7D%20%5C%5C%20%20%5C%5C%20%3D%20%20%28x%20-%20y%29%28x%20-%20y%20%2B%20a%29)
Answer:
y=-9
Step-by-step explanation:
slope intercept form: y=mx+b, m being the slope
y=6 times -3
since there isn't a y intercept, you can't really put it in standard form unless I missed a step.
y= -9
Answer: 8 1/4g/cm³
Step-by-step explanation:
Given the graph :
The rate of change in the mass of copper with respect to volume :
To obtain this, we find the slope or gradient of the graph:
Gradient = Δy / Δx = (y2 - y1) / (x2 - x1)
Drawing a right angled triangle on the anybpart of the line of best fit:
y2 = 40 ; x2 = 4.75 ; y1 = 16 ; x1 = 2
(y2 - y1) / (x2 - x1)
= (40 -16) / (4.75 - 2)
= 24 / 2.75
= 2400/275
= 8.727 g/cm^3
Due to unit and graph scale,, the slope is closest to 8 1/4g/cm³
Answer:
x = 7
Step-by-step explanation:
6 - 4x = -22
-6 - 6
-4x = -28
x = -28/-4
x = 7
