Suppose the leftmost digits of two numbers are 8 and 3. Can you tell which number is greater if so explain.
Irina-Kira [14]
You cannot tell which number is greater just by the leftmost digits. This is because you do not know how many digits each number has. Ex: 80 and 3,000

What is the equation for g, which is f(x) = 2x2 + 3x − 1 reflected across the y-axis? Group of answer choices g(x) = −2x2 − 3x −
Sergio [31]

Answer:

g(x) = 2x^2 - 3x - 1

Step-by-step explanation:

Given

f(x) = 2x^2 + 3x - 1

Required

Determine g(x), if f(x) is reflected across the y axis

<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>

<em />

In other words,

g(x) =  f(-x)

Calculating f(-x)

f(-x) = 2(-x)^2 + 3(-x) - 1

f(-x) = 2x^2 - 3x - 1

Substitute g(x) for f(-x)

g(x) = 2x^2 - 3x - 1

<em>Hence;</em>

g(x) = 2x^2 - 3x - 1

Vlada [557]

Answer:

MON= 57

Step-by-step explanation:

5x-23+3x-15=90

8x-38=90

8x=128

x=16

PLUG 16 INTO MON EQUATION

5(16)-23=57

therefore,

MON=57

USE COMPLEMENTARY FOR PROBLEMS LIKE THIS :)))

(btw, assuming that the angle is 90 degrees)
