y=3x+6

Step-by-step explanation:

point 1 (2;12)

point 2 (4;18)

$m = \frac{y2 - y1}{x2 - x1}$

$m = \frac{18 - 12}{4 - 2}$

$m = \frac{6}{2}$

m=3

y=mx+b

sub in a point and gradient

12=3(2)+b

12=6+b

b=6

y=3x+6

Evaluate the following expression when x = 6 and y = 2:

Liula [17]

Answer:

11/2

Step-by-step explanation:

$\frac{ {x}^{2} + {y}^{3} }{2 + x} \\$

when,

$x = 6 \\ y = 2$

Now substitute the value we get,

$\frac{ {6}^{2} + {2}^{3} }{2 + 6} \\ \\ = \frac{36 + 8}{8} \\ \\ = \frac{44}{8} \\ \\ = \frac{11}{2}$

A rectangular poster has an area of 190 inches squared. The height of the poster is one inch less than twice its width. Find the

Annette [7]

Set the height to h, and the width to w.

We know that wh=190 and h=2w-1.

Substituting 2w-1 for h, we have:

w(2w-1)=190

So:
2w^2-w-190=0

Factoring this equation, we get (2w+19)(w-10)=0. The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
