Answer:

slope: -11/7

Step-by-step explanation:

Slope is equal to the change in yy over the change in xx, or rise over run.

m=change in ychange in xm=change in ychange in x

The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).

m=y2−y1x2−x1m=y2-y1x2-x1

Substitute in the values of xx and yy into the equation to find the slope.

m=19−(8)−9−(−2)m=19-(8)-9-(-2)

Simplify.

m=−11/7

Answer:

m=-1\frac{4}{7}

Step-by-step explanation:

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-2,\:8\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:19\right)\\\\m=\frac{19-8}{-9-\left(-2\right)}\\\\m=\frac{11}{-9+2}\\\\m=\frac{11}{-7}  \\\\m=-\frac{11}{7}\\\\m=-1\frac{4}{7}

Given g(x)= -2x+2 and f(x)= 3x^2+4, find (g+f)(-3)
aliina [53]

Answer:

39

Step-by-step explanation:

g(x)= -2x+2 and f(x)= 3x^2+4

(g+f)(-3)

g(-3) = -2(-3) +2 = 6+2 =8

f(-3) = 3 (-3)^2 +4 = 3(9)+4 = 27+4 = 31

(g+f)(-3) = g(-3) + f(-3) = 8+31 = 39

Find the population density of each state. round to the nearest 10th.
matrenka [14]
Population density = population/area

Califonia = 36,500,000 / 163,707 = 223.0 persons per square mile
Florida = 18,300,000 / 65,758 = 278.3 persons per square mile
Iowa = 2,990,000 / 56,276 = 53.1 persons per square mile
New Jersey = 8,690,000 / 8,722 = 996.3 persons per square mile
Wyoming = 522,000 / 97,818 = 5.3 persons per square mile
