Just plus in x for -3
f(x) = 4(-3)^2 + 3(-3) - 11
f (x) = 4(9) -9 - 11
f(x) = 36 - 20
f(x) = 16

Which shows the graph of the solution set of 2x + 3y ≤ 6?
irina [24]
The dividing line will have to hit the points (0,2) and (3,0)
then you can test the point (0,0) which satisfies the inequality, so you will shade the side that has (0,0) on it, so it's the first picture.

The required scale model will be 1:6.24  10^9

<h3>Finding scale factors</h3>

A  scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure.

Given the following parameters

Distance of sun to Jupiter = 7.8 * 10^8 km

If the distance of sun to Jupiter is 8m on his scale, hence the value of n is calculated as;

n = 8 * 7.8 *10^8

n = 62.4 * 1068

n = 6.24  10^9

Hence the required scale model will be 1:6.24  10^9
