M = y2-y1/x2-x1

m = 4-(-2)/-3-5

m = 6/-8

m= -6/8 = -3/4 (simplified)

A(x+1)(x-1)+b(x-2)(x+1)+(x+1)^2=9x-x-10 What is a+b?

igor_vitrenko [27]

a(x+1)(x-1)+b(x-2)(x+1)+(x+1)^2=9x^2-x-10

(x+1)(a(x-1)+b(x-2)+(x+1))=(x+1)(9x-10)

a(x-1)+b(x-2)+x+1=9x-10

Now this equation is much simpler!

(a+b)x-a-2b+x+1=9x-10

(a+b)x-a-2b=8x-11

(a+b-8)x-a-2b-11=0

a+b-8=(a+2b-11)/x

I can't solve it 3 variables and 1 equations means infinite answers so yea.

BD is the angle bisector of ZABC.

mojhsa [17]

Answer:

B:25°

Step-by-step explanation:

Now $\angle ABC$ gets bisected by $BD$ .

$\angle ABD=25^{\circ}$

Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.

We know that one of the angles is $25^{\circ}$ so the other angle has to be $25^{\circ}$ also.

Hence, the $m\angle DBC=25^{\circ}$ .

. A trader bought A TV set for Birr 2000 and sold it at loss of 11/2% what:was the selling price?

olga nikolaevna [1]

Answer:

1890

Step-by-step explanation:

Loss = 11/2 % = 5.5 %

Cost price = 2000

Loss = 5.5% of cost price

= 5.5% * 2000

$= \frac{5.5}{100}*2000\\\\= 5.5*20\\= 110$

Selling price = Cost price - loss

= 2000 - 110

= 1890
