What is the degree of angle e and g

Zina [86]

Answer:

e=g = 126 degree

Step-by-step explanation:

e = g (opposite angles's property)

g+ b = 180 ( supplementary angles's property)

b = 54 degree (opposite angles's property)

-> g = 180-54 = 126

-> e = 126 degree

How can you rewrite equations like 2,000 = 20x + 10y to express x as a function of y? To

anzhelika [568]

Answer:

see below

Step-by-step explanation:

to express x as a function of y we need to form this

$y=mx+b$

and to express y as a function of x

$x=ay+c$

so we work

1)

$2000=20x+10y\\\\2000-20x=10y\\\\y=-2x+200$

2)

$2000=20x+10y\\\\2000-10y=20x\\\\x=-\frac{1}{2}x+100$

A parallelogram has an area of x2+ 9x− 36.

Serhud [2]

Answer:

a) Length $x + 12$ , Width $x - 3$ , b) $x = 3$

Step-by-step explanation:

a) The expressions for the length and width of the parallelogram can be determined by factorizing the polynomial:

$A = x^{2} + 9\cdot x - 36$

$A = (x+12)\cdot (x-3)$

Length

$x + 12$

Width

$x - 3$

b) Since area is a positive variable, the set of solutions encompass all values of x such that area is zero o greater. Then, there are two interval where A is positive:

- When both binomials are negative.

$x \leq 3$ and $x \leq -12$

$x \leq -12$

- When both binomials are positive.

$x \geq 3$ and $x \geq -12$

$x \geq 3$

Since x is an integer, x must be positive and therefore the least possible value of x is:

$x = 3$
