ERROR ANALYSIS Describe and correct the error in ﬁnding the x-intercept.

EastWind [94]

The x-intercept is -6

Step-by-step explanation:

In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0

In the given method, x is put equal to zero instead of y as x-intercept had to be found.

Given equation is:

$-2x+3y=12$

$-2x + 3(0) = 12\\-2x +0 = 12\\-2x = 12$

Dividing both sides by -2

$\frac{-2x}{-2} = \frac{12}{-2}\\x = -6$

The x-intercept is -6

An airplane needs to head due north, but there is a wind blowing from the northeast at 50 km/hr. The plane flies at an airspeed

laiz [17]

Answer: $\theta =2.415^{\circ}$

Step-by-step explanation:

Using vector method to solve it

Resultant can be given by

$R^2=700^2+40^2+2\times 700\times 40cos135$

$R^2=450,408$

R=671.12 Km/hr

The angle made by resultant with 700 km/hr is $\theta$

using sine rule

$\frac{40}{sin\theat }=\frac{R}{sin45}$

$sin\theta =0.0421509$

$\theta =2.415^{\circ}$

$-7x-9y=-8$

$5x+6y=4$

$-35x-45y=-40$

$35x+42y=28$

$-3y=-12$

$y=4$

$5x+6(4)=4$

$5x+24=4$

$5x=-20$

$x=-4$

$(-4,4)$

Hope this helps.

頑張って!
