-BARSIC- [3]

Answer:

Step-by-step explanation:

-6x²+15x+9=0

divide by -3

2x²-5x-3=0

2x²+x-6x-3=0

Use the figure to find the measure of angle 1. *
QveST [7]

Answer:  angle 1 = 110 degrees

This is because angle 1 and the red 110 degree angle are corresponding angles.

They correspond to one another due to the fact they are both in the southwest corner of each 4-corner angle configuration (which is the result of crossing two lines)

Corresponding angles are congruent only when we have parallel lines like this.

Multiply and Simplify<br> (x-4)(-5x - 6)
zmey [24]

Answer:

-5x^2 +14x +24

Step-by-step explanation:

(x-4)(-5x - 6)

FOIL

first : x*-5x = -5x^2

outer : -6x

inner: -4*-5x = 20x

last: -4*-6 = 24

Add them together

-5x^2 -6x+20x +24

-5x^2 +14x +24

By using the digits 0 to 9, the boxes are filled with their respective numerical values to make the chart accurate as shown in the image attached below.

<h3>What is a function?</h3>

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.

<h3>The types of function.</h3>

In Mathematics, there are different types of functions and these include the following;

  • Periodic function
  • Inverse function
  • Modulus function
  • Signum function
  • Piece-wise defined function.
  • Logarithm function

<h3>What is a logarithm function?</h3>

A logarithm function can be defined as a type of function that represents the inverse of an exponential function. Mathematically, a logarithm function is written as follows:

y = logₐₓ

y = log₁₀10

y = log₁₀10 = 1.  

Therefore, if log₁₀x < 1, then, x < 10.  Also, if log₁₀x > 1, then, x > 10.

For this exercise, you should take note of this deductive points:

  • The upper left number can't be smaller than 1 but its log must be the smallest. Thus, if the exponent equals 0, the red box can assume any number.
  • The fractions in the lower left and upper right should be as large as possible with their denominators being small while their numerators are large.

In conclusion, by using the digits 0 to 9, the boxes are filled with their respective numerical values to make the chart accurate as shown in the image attached below.
