Example
3 ÷ 93
first, how many times does three go into nine
then,subtract that from nine
after that how many times does three go into three
Answer:
5*p^2*q+10q = 5p^2*q + 10q
Step-by-step explanation:
5 * p squared * q + 10q = 5p^2*q+10q
The short cut formula for finding equation of two points
(x₁, y₁) and (x₂, y₂)
is:
(y - y₁) / (y₂- y₁) = (x - x₁) / (x₂ - x₁).
Substituting: x₁ = -3, y₁ = 2, x₂ = 7, y₂ = -1
(y - 2) / (-1 - 2) = (x - -3) / (7 - -3)
(y - 2) / -3 = (x + 3) / (7 + 3)
(y - 2) / -3 = (x + 3) / 10
10*(y - 2) = -3*(x +3)
10y - 10*2 = -3*x - 3*3
10y - 20 = -3x - 9
10y + 3x = -9 +20
10y +3x =11
Hence equation is: 10y + 3x = 11
Hope this explains it.
This is a quadratic equation with a general equation of ax^2 + bx + c.
The quadratic formula can help to get the roots of the equation. We know the highest degree of that equation is 2; so there will be also two roots.
The quadratic formula is
x = [-b ± √(b^2 - 4ac)] / 2a
With a = 1, b = 7, c = 2,
x = {-7 ± √[(7)^2 - 4(1)(2)]} / 2(1) = (-7 ± √41) / 2
So the two roots are
x1 = (-7 + √41) / 2 = -0.2984
x2 = (-7 - √41) / 2 = 0.2984
This is also another way of factorizing the equation
(x + 0.2984)(x + 0.2984) = x^2 + 7x + 2
Answer:
20in
Step-by-step explanation:
To find the rate of which they are similar all you have to do is divide 10 by 4 or 15 by 6 to get a rate of 2.5 then multiply that rate by 8 to find your answer
