standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient



a. The gradient is


b. The gradient at point P(1, 2) is

c. The derivative of
at P in the direction of
is

It looks like

so that

Then


We have to add 8/15 to 2/5.
To add two fractions we have to make them have the same denominator, so we have to convert 2/5 to have a denominator of 15. To do this, we have to multiply 2/5 by 3 and then we can add the fractions:

Answer: 14/15
Answer:
282.7 cm
Step-by-step explanation: One spin is one circumference. That's π(diameter)= 282.7
Answer:
Multiply 0.25x by 8
Step-by-step explanation:
82.5 + 8(0.25x) = 338.5
Multiply 0.25x by 8 we get,
8 × 0.25x = 2x
Thus, 82.5 + 2x = 338.5
