Mathematics
1 answer:
maks197457 [2]3 years ago
5 0
The quadratic equation y = ax^2 +bx+c can be written in the form:
y = a(x-p)(x-q)
Where p and q are the roots of the equation.
Given p = 4, q = -2, a = 3, the quadratic will look like this:
y = 3(x-4)(x+2)
Finally, distribute and combine like terms to put it in standard form.
y = 3(x^2 - 4x+2x -8) \\  \\ y = 3(x^2 -2x-8) \\  \\ y = 3x^2 -6x -24

Help plzzz!! Find the slope through these pairs of points
Colt1911 [192]
We can use the formula y2-y1/x2-x1 to find the slope.

1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.

2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.

3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.

4. -17-3/-11-(-1) is -20/-10. The slope is 2.

Raman mixed juice and water in the ratio 2 : 3 and Meera mixed juice and water in the ratio 1 : 4. They then mixed 150 ml of Ram
Kay [80]

Answer:

80

Step-by-step explanation:

ramans ratio is 2:3

so in 150ml there are 2 parts of juice and 3 parts of water

2x + 3x = 150

x = 30

so, juice in 150 ml of raman's mixture = 2x = 2* 30 = 60ml

meera ratio is 1:4

similarly,

1y + 4y = 100

y = 20

so, juice in 100 ml of meera's mixture is y = 20ml

so, quanitity of juice in final mixture is 60 + 20 = 80
