Write the equation of a line that passes through (-1, -2) and has a slope of 2 in point-slope form. 2.) Given the function f(x)=5x^2-2f ( x ) = 5 x 2 − 2, find f(-3)f ( − 3 ). Please show your work.

3.) For inequalities, when do you use a solid line versus a dotted line? How is the shading determined?

Step-by-step explanation:

Equation of straight line: y=mx+b

Given slope=2, hence m=2

y=2x+b

Replace y and x values as stated in the question (-1, -2)

(-2)=2(-1)+b

-2+2=b

b=0

rewrite the equation:

y=2x+0

y=2x

For 3) a solid line is used when the equation is <= or => while dotted line is for when the equation is < or >

Could you elaborate on question 2? I dont quite get what the question is asking for

were is the equation

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450
