Remember, you can do anything to an equation as long as you do it to both sides

we hates fractions
times both sides by 3
(we could have added 1/3b to both sides but I'm lazy)

4b+6=12-b
add b to both sides
5b+6=12
minus 6 both sides
5b=6
divide both sides by 5
$b=\frac{6}{5}$

A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2,

Oksanka [162]

Answer:

A. one B. (3, 4)

Step-by-step explanation:

1. A good graph can answer both parts (see attached image).

2. Write equations for the two lines and find a simultaneous solution.

Line A: Slope from (2, 6) to (5, 0) is $m=\frac{6-0}{2-5}=\frac{6}{-3}=-2$

Using point-slope form $y-y_1=m(x-x_1)$

$y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10$

Line B: Slopt from (6, 6) to (0, 2) is $m=\frac{6-2}{6-0}=\frac{2}{3}$

Using point-slope form, the equation for Line B is

$y-2=\frac{2}{3}(x-0)\\y=\frac{2}{3}x+2$

To find the simultaneous solution, set the <em>y's </em>equal.

$-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3$

Find <em>y</em> using either equation to get y = 4.

13. The lengths of two adjacent sides of a parallelogram are 7 cm and 5 cm respectively.

SashulF [63]

Answer:

perimeter of the required parallelogram = 24 cm

Step-by-step explanation:

perimeter of parallelogram = 2( l + b ) = 2 ( 7 + 5 )

= 2 × (12)

= 24 cm
