Answer:

The solution is the point (1,-4)

Step-by-step explanation:

we have

$y=-3x-1$ ----> equation A

$y=-2x-2$ ----> equation B

we know that

The solution of the system of equations by graphing is the intersection point both graphs

using a graphing tool

The intersection point is (1,-4)

see the attached figure

therefore

The solution is the point (1,-4)

Find a polynomial f(x) of degree 4 that has the following zeros. 0, -5, 8, -2

Roman55 [17]

Answer:

The polynomial of the function degree '4'

x⁴ - x³ -46 x² -80x =0

Step-by-step explanation:

Explanation:-

Given zeros are 0 ,-5,8,-2

x =0 , x=-5 ,x=8 and x=-2

(x-0) , ( x+5) , (x-8) and (x+2)

The polynomial function with degree '4'

(x-0)(x-(-5)(x-8)(x-(-2) =0

x ( x+5) (x-8) (x+2) =0

(x² +5x)(x-8)(x+2) =0

(x³ -8 x²+5x² -40 x)(x+2) =0

( x³ -3 x² - 40 x) (x +2) =0

x⁴ + 2 x³ - 3 x³- 6 x²-40 x²- 80 x =0

x⁴ - x³ -46 x² -80x =0

Final answer:-

The polynomial of the function degree '4'

x⁴ - x³ -46 x² -80x =0

Solve for X .... -3(x-5)>18

Ilya [14]

Answer:

x<-1

Step-by-step explanation:

We multiply by -1 of both sides and change the sense of inequality:

(-1)*(-3(x-5))>(-1)*18

3(x-5)<-18

3 passes by dividing

x-5<-18/3

x-5<-6

5 goes by adding:

x<-6+5

x<-1
