Solve 15x+3y=9,10x+7y=-4

TiliK225 [7]

Answer:

x = 1, y = -2

Step-by-step explanation:

15x + 3y = 9 (1)

10x + 7y = -4 (2)

3 × (2) - 2 × (1)

3 × (2)

30x + 21y = -12 (3)

2 × (1)

30x + 6y = 18 (4)

(3) - (4)

15y = -30

y = -30 / 15

y = -2

sub y = -2 into (1)

15x + 3y = 9

15x + (3 × -2) = 9

15x - 6 = 9

15x = 9 + 6

15x = 15

x = 15 / 15

x = 1

the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an

kari74 [83]

Given:

The equation of given line is

$y=3x-4$

A line is perpendicular to the given line and passes through the point (9,5).

To find:

The equation of the perpendicular line.

Solution:

We have,

$y=3x-4$

On comparing this equation with slope intercept form $y=mx+b$ , we get

$m=3$

It means, the slope of the given line is 3.

The product of slopes of two perpendicular lines is -1.

$m\times m_1=-1$

$3\times m_1=-1$

$m_1=-\dfrac{1}{3}$

Point slope form of a line is

$y-y_1=m(x-x_1)$

Where, m is the slope.

The slope of perpendicular line is $-\dfrac{1}{3}$ and it passes through the point (9,5). So the equation of the line is

$y-5=-\dfrac{1}{3}(x-9)$

$y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)$

$y-5=-\dfrac{1}{3}x+3$

Adding 5 on both sides, we get

$y-5+5=-\dfrac{1}{3}x+3+5$

$y=-\dfrac{1}{3}x+8$

Therefore, the equation of required line is $y=-\dfrac{1}{3}x+8$ .
