I can’t really explain but this is my working step by step, hope u can understand and see if it helps you :)
Answer:
The answer is b. 4*3 2/5.
Step-by-step explanation:
It states 4 times the amount Ruby mixed. Ruby mixed it 3 2/5 solution. So you would right out 4 x 3 2/5.
Where’s the model? If it says choose a model, there should be a model
Answer:
The equation of the line with slope m = 2 and passing through the point (1, 1) will be:

Step-by-step explanation:
We know that the point-slope form of the line equation is

where
- m is the slope of the line
The formula
is termed as the point-slope form of the line equation because if we know one point on a certain line and the slope of that line, then we can easily get the line equation with this formula and, hence, determine all other points on the line.
For example, if we are given the point (1, 1) and slope m = 2
Then substituting the values m = 2 and the point (1, 2)




Therefore, the equation of the line with slope m = 2 and passing through the point (1, 1) will be:

Answer:
y = 2x + 54
Step-by-step explanation:
slope of equation:
(y2-y1)/(x2-x1)
= (72-58)/(9-2)
= 14/7
= 2
y = 2x + b
58 = 2(2) + b
58 = 4 + b
b = 54
