Answer: a= g+2 / 2

Step-by-step explanation:

g= -2 + 2a

>> -2+2a=g ( side change )

>> -2+2a +2 = g+2 ( adding 2 both side)

>> 2a = g+2

>> 2a /2 = g+2 /2 ( divide by 2 both side)

>> a= g+2 /2

The school is selling potted plants as a fundraiser.Kara sold 12 ferns and 8 ivy plants for $260.Paul sold 15 ivy plants and 6 f
vovangra [49]

x=ferns ; y=ivy

12x+8y=260

6x+15y=240

x=60 -(15/6)y

12(60+ (15/6)y + 8y = 260

x=60 -(15/6)y

720 - 30y + 8y = 260

x=60- (15/6)y

-30y +8y= 260-720 ==> -22y= -460

x=60 -(15/6)y

y= (-460)/(-22)= 20.9090909091

y=20.90

x=60 -(15/6)×20.90= 7.75

×(ferns)=7.75$

y(ivy)=20.90$

Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (3, 1, 0) and perpendicu
iren2701 [21]

Answer with Step-by-step explanation:

We are given that a point (3,1,0)

Two vectors are

A=<1,1,0>

B=<0,1,1>

A\times B=\begin{vmatrix}i&j&k\\1&1&0\\0&1&1\end{vmatrix}

A\times B=i-j+k

Let v=A\times B=i-j+k

v==

r_0==

r=r_0+vt

Substitute the values then we get

r=+t

r=

The parametric equation of the line

x=x_0+at,y=y_0+bt,z=z_0+ct

Using the formula

The parametric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by

x=3+t,y=1-t,z=t

The symmetric equation of the line is given by

\frac{x-x_0}{a}=\frac{y-y_0}{b}=\frac{z-z_0}{c}

Using the formula

The symmetric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by

\frac{x-3}{1}=\frac{y-1}{-1}=z
