Horizontal (left to right) is x values
look at wher it says 1
now go up untill you hit the darker line, it seems that it went 0 units up
the value of the function at x=1 is 0

If y=2-3x/x+3 express x in terms of y<br> [20pts]

ollegr [7]

Answer:

a. x = (2 -3y)/(y+3)

b. x = -4/5

Step-by-step explanation:

Clear the fraction, collect x terms, divide by the coefficient of x.

$y=\dfrac{2-3x}{x+3}\\\\y(x+3)=2-3x\\\\3x+xy=2-3y\qquad\text{add $3x-3y$}\\\\x(y+3)=2-3y\qquad\text{factor out x}\\\\\boxed{x=\dfrac{2-3y}{y+3}}\qquad\text{divide by the coefficient of x}$

Put 2 where y is and do the arithmetic.

x = (2 -3(2))/(2 +3) = (2 -6)/5

x = -4/5

The figure shows trapezoid ABCD on a coordinate plane.

docker41 [41]

Answer:

121 unit^2.

Step-by-step explanation:

The area = height/2 * ( sum of the opposite parallel lines)

= h/2(BC + AD

h = BF = 14 - 3 = 11 units.

BC = 13 - 5 = 8 units.

AD = 16 - 2 = 14 units.

Area = (11/2)(8 + 14)

= 5.5 * 22

= 121 unit^2.

Write the linear equation 5x-15y=-8 in slope-intercept form?

mylen [45]

Y=(1/3)x+(8/15). Just subtract the 5x over and then divide everything by -15 to get y by itself.
