ella [17]2 years ago
8 0

Answer:

f(x)=5x^3-2x^2-90x-36=0

=x^2(5x-2)-18(5x-2)=(x^2-18)(5x-2)=0

x^2-18=0/5x-2=0

x^2=18=x=9√2

5x-2=0

x=2/5

zeros are 9√2,2/5

write an equation in slope-intercept form of the line whose y-intercept is -3 and the line is perpendicular line whose equation
Artemon [7]

first you need to find the slope of he current equation by changing it to y=mx+b

3x-2y=9  subtract 3x from both sides

-2y=-3x+9  divide both sides by -2

y+3/2x-9/2  Your slope of the existing is 3/2 or 1 1/2

a perpendicular line has the opposite reciprocal slope so 3/2 would be -2/3

-3 is your y intercept. now you can make your equation

y=-2/3x-3

Maggie's brother is 3 years younger than four times her age. The sum of their ages is 62. How old is Maggie? Maggie is years old
Nadusha1986 [10]

Answer:

Maggie is 13 years old.

Step-by-step explanation:

1M + 1B = 62

rearrange to get:

1B = 62 - 1M

4M - 3 = 1B

substitute B with 62 - 1M so there is only one variable. this gives:

4M - 3 = 62 - 1M

Get all the variables on one side:

4M + 1M - 3 = 62

Get all non variables on the other side:

4M + 1M = 62 + 3

simplify:

5M = 65

Divide both sides by 5 to get the M by itself:

M = 13.

BONUS:

M + B = 62

B = 49

So her brother is 49 years old.

Maggie is 13 years old.
