Answer:

The simplified equivalent expressions for given expression as below:

A) 2x+10x=12x

B) -4(3x-10)+5(2-6x)=-42x+50

C) 2(x-4)+x=3x-8

D) -3-7(3-4x)+8x=36x-24

Step-by-step explanation:

A) Given expression is 2x+10x

To simplify the expression using distributive property a(x+y)=ax+ay

2x+10x=12x (adding the terms)

B) Given expression is -4(3x-10)+5(2-6x)

To simplify the expression using distributive property a(x+y)=ax+ay

-4(3x-10)+5(2-6x)=-12x+40+10-30x

-4(3x-10)+5(2-6x)=-42x+50 (adding the like terms)

C) Given expression is 2(x-4)+x

To simplify the expression using distributive property a(x+y)=ax+ay

2(x-4)+x=2x-8+x (adding the like terms)

2(x-4)+x=3x-8

D) Given expression is -3-7(3-4x)+8x

To simplify the expression using distributive property a(x+y)=ax+ay

-3-7(3-4x)+8x=-3-21+28x+8x (adding the like terms)

-3-7(3-4x)+8x=-24+36x

-3-7(3-4x)+8x=36x-24

Q.2

Katen [24]

Answer:

Q2. (16,8)

Q3. $k=\frac{2}{3}$ , ratio=5:1

Q4. Ratio=2:1

Q5. Ratio=1:1

Step-by-step explanation:

Q2. Let (2a,a) be the coordinates of P.

Since P is equidistant from Q (2,-5) and R (-3, 6), we have

$|PQ|=|PR|$

This gives us:

$\sqrt{(2a-2)^2+(a+5)^2}=\sqrt{(2a+3)^2+(6-a)^2}$

$\implies (2a-2)^2+(a+5)^2=(2a+3)^2+(6-a)^2$

Expand:

$4a^2-8a+4+a^2+10a+25=4a^2+12a+9+a^2 -12a+36$

$2a=16$

$a=8$

The coordinates of P are $(16,8)$

Q.3 The equation of the line segment joining the points

A (5.-6) and B (-1,-4) is $x+3y=-13$ .

The x-coordinate of the point that divides AB in the ratio m:n is

$x=\frac{mx_2+nx_1}{m+n}$

The y-axis meets this line at $(0,-\frac{13}{3})$

We substitute $x_2=-1,x_1=5,x=0$ into this equation and solve for m and n.

$0=\frac{-m+5n}{m+n}$

$m=5n$

$\frac{m}{n}=\frac{5}{1}$

Therefore the ratio is m:n=5:1

Q.4 The equation of the line segment joining

the points (-5,-4) and (-2,3) is $-7x+3y=23$ .

The point (-3, k) must satisfy this line because it lies on it.

$-7(-3)+3k=23$ .

$\implies k=\frac{2}{3}$

We again use the equation $x=\frac{mx_2+nx_1}{m+n}$ to find the given ratio.

Substitute: $x_2=-2,x_1=-5$

$4=\frac{-2m+-5n}{m+n}$

$\implies m=2n$

$\frac{m}{n}= \frac{2}{1}$

The ratio is m:n=2:1

Q. 5 The equation of the line joining A (2,3) and B(6,-3) is $3x+2y=12$ .

We substitute (4,m) to get:

12+4m=12

4m=0

m=0

It is obvious that: (4,0) is the midpoint of A(2,3) and B(6,-3).

Hence the ratio is 1:1
