f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

What can you conclude about the population density from table provided

vaieri [72.5K]

The population density of an area is the number of people living in per unit area. The most populated region is Region A.

<h3>What is Population Density?</h3>

The population density of an area is the number of people living in per unit area. It is given by the formula,

$\text{Population Density}=\dfrac{\text{Population of the area}}{\text{Total area}}$

The population density of the different regions is as follows,

Region A = 20,178 person /521 km² = 38.729 person/km²

Region B = 1,200 person /451 km² = 2.66 person/km²

Region C = 13,475person /395 km² = 34.114 person/km²

Region D = 6,980 person /426 km² = 16.385 person/km²

Hence, The most populated region is Region A.

Mashcka [7]

You have 1/4 divided by 2 which is the same as 1/4 divided by 2/1. First, find the reciprocal of 2/1 which is 1/2. You now have the problem 1/4 x 1/2. Multiple across.
