Can someone please help me solve this? 2x+5y=-1 -10x-25y=5

Mathematics
1 answer:

this is system of equations

2x + 5y = -1   times this one by 5 to make the y's opposite

-10x -25y = 5

10x - 25y = -5  (this is it times by 5, now add them)

__________

0 + 0       = 0    

now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.

Can some one help me.
alina1380 [7]

Answer:

x = ± 2, x = 3

Step-by-step explanation:

note that x = 2 gives

2³ - 3(2)² - 4(2) + 12 = 8 - 12 - 8 + 12 = 0

Hence x = 2 is a root and (x - 2) is a factor

x³ - 3x² - 4x + 12 ÷ (x - 2)

= (x - 2)(x² - x - 6)

= (x - 2)(x + 2)(x - 3), hence

(x - 2)(x + 2)(x - 3) = 0

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x + 2 = 0 ⇒ x = - 2

x - 3 = 0 ⇒ x = 3

Write an equation for the perpendicular line to the line whose equation is 4y-5x=20 that contains the point (-2,-3)
yuradex [85]

Answer:

4x + 5y = - 23

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 4y - 5x = 20 into this form

add 5x to both sides

4y = 5x + 20 ( divide all terms by 4 )

y = \frac{5}{4} x + 5 ← in slope-intercept form

with slope m = \frac{5}{4}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m}, hence

m_{perpendicular} = - 1 / \frac{5}{4} = - \frac{4}{5}

y = - \frac{4}{5} x + c ← is the partial equation

to find c substitute (- 2, - 3) into the partial equation

- 3 = \frac{8}{5} + c ⇒ c = - \frac{23}{5}

y = - \frac{4}{5} x - \frac{23}{5} ← in slope-intercept form

multiply all terms by 5

5y = - 4x - 23 ( add 4x to both sides )

4x + 5y = - 23 ← in standard form
