we are given

graph of a quadratic function

Quadratic function:

Those function which has degree=2

we can write it as

$y=ax^2+bx+c$

Since, the degree is 2

so, the shape of the curve will be parabolic

so, option-B.........Answer

What is the slope of a line parallel to the line whose equation is 3x – 4y = 8

liq [111]

Hi there! The answer is C.

We can find the slope of this line by making y the subject of the equation.

$3x - 4y = 8 \\ - 4y = - 3x + 8 \\ y = \frac{ - 3}{ - 4} x + \frac{8}{ - 4} \\ y = \frac{3}{4} x - 2$

Now we can see that the slope of this line (which is positioned in front of x) is 3/4. Therefore, the slope of any line parallel to this one is 3/4 as well. The answer is C.

How much water do you add…To make 25% sugar syrup using 15g sugar?

zepelin [54]

25% sugar syrup means it has 25% sugar and 75% water

Let the total weight of solution is 'x'

amount of sugar = 15g = 25% of x = x/4

x/4 = 15

x = 60

so, amount of water required is = 75 % of x = 3/4 x

putting x = 60

amount of water required = 45 g
