Darina [25.2K]

Answer:

P>-\frac{6}{5}

Step-by-step explanation:

Isolate the variable by dividing each side by factors that dont't contain the variable.

2(P+1)+3(P+2)>2

2P+2+3P+6>2

5P+8>2

     -8    -8

5P>-6

Divide both sides by 5.

P>-\frac{6}{5}

Write the formula for absolute value function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).
valentinak56 [21]

First you need to find the slope of the line:

m =   \frac{y_2 - y_1}{x_2 - x_1}

m=6-(-2) / (-1)-0 =-8

equation of line is:

y=mx+b

y=-8x+6

for absolute value function:

if x<0

y=-8x+6

if x>0

y=+8x-6
