A parallelogram without four right angles would prove that to be false.

Yep that'd be false since they are also rectangles

2 rational numbers are C. 2.777 and D. -7/3

a rational number<span> is any </span>number<span> that can be expressed as the quotient or fraction p/q of two integers
</span>
as you know 0.7777 (7 repeat) = 7/9
so 2.777(7 repeat) = 2 7/9

Step-by-step explanation:

<u>5</u><u>)</u><u> </u>2.4×10^-5 / 4.5×10^-11

  • 2.4×10^-5= 0.000024
  • 4.5×10^-11= 0.000000000045

=0.000024/0.000000000045

=24/1 × 1,000,000/45

=24,000,000/45

=533,333.33°

=5.33333°×10^5

  1. 2x + 3 = 5x - 2

  • 2x - 5x = - 2 - 3
  • -3x = -5
  • x = -5/-3
  • x = 1.66°

  1. 6x + 4 = 6x + 4
  • 6x - 6x = 4 - 4
  • 0x = 0

  1. 2 (2x + 3) = 8x - 2
  • 4x + 6 = 8x - 2
  • 4x - 8x = -2 - 6
  • -4x = -8
  • x = -8/-4
  • x = 2

  1. -3x + 2 = -3x + 5
  • -3x + 3x = 5 - 2
  • 0x = 3

Letter be has no solution because it is broken down as "0x = 0"

Mary is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect? Which coordinates if they do? Negat
Umnica [9.8K]

Answer:

The graphs of the two function will not intersect.

Step-by-step explanation:

We are given a quadratic function f(x).

Also g(x) is given by a set of values as:

 x            g(x)

 1              -1

  2             0

  3              1

As g(x) is a linear function hence we find out the equation of g(x) by the slope intercept form of a line: y=mx+c

let g(x)=y

when x=1 ,   g(x)=-1

-1=m+c----(1)

when x=2   , g(x)=0

0=2m+c------(2)

Hence, on solving (1) and (2) by method of elimination we get:

m=1 and c=-2

Hence, the equation of g(x) is:

g(x)=x-2

So clearly from the graph we could see that the graph of the two functions will never intersect.
