Mathematics
1 answer:
const2013 [10]3 years ago

Answer:

25 degrees

Step-by-step explanation:

The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees.  Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.

x is 25 degrees.

This is based upon the "corresponding angles" principle.  Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.

Which conclusion about f(x) and g(x) can be drawn from the table
NeTakaya
<h2>Answer:</h2>

The conclusion that is true about f(x) and g(x) based on the table of values is:

  •      The function f(x) and g(x) are reflections over the y-axis.    
<h2>Step-by-step explanation:</h2>
  • We know that the rule that describes the reflection over the y-axis is:

        (x,y) → (-x,y)

Hence, if we have a function f(x) as:

f(x)=2^x

Then it's reflection over the y-axis is:

f(-x)=2^{-x}\\\\\\f(-x)=(2^{-1})^x\\\\\\f(-x)=(\dfrac{1}{2})^x\\\\i.e.\\\\\\g(x)=(\dfrac{1}{2})^x

Hence, they are reflection over the y-axis.

  • Also, we know that the exponential function of the type:

                y=ab^x

where a>0 is a increasing function if b>1

and is a decreasing function if: 0<b<1

Hence, f(x) is a increasing function and g(x) is a decreasing function.

  • Also, the initial value of a function is the value of function when x=0

when x=0 we see that both f(x)=g(x)=1

i.e. Both f(x) and g(x) have same initial value.

Also,by the graph we may see the relation.

Let m = 6x + 5.
arsen [322]

We have been given that m=6x+5. We are asked to write (6x + 5)^2-10 =-18x-15 in terms of m.

First of all, we will factor -3 from right side of equation as:

(6x + 5)^2-10 =-3\cdot 6x-3\cdot 5

(6x + 5)^2-10 =-3( 6x+5)

Now we will substitute m=6x+5 in our equation as:

(m)^2-10 =-3(m)

m^2-10 =-3m

Upon adding 3m on both sides, we will get:

m^2+3m-10 =-3m+3m

m^2+3m-10 =0

Therefore, the equation m^2+3m-10 =0 is equivalent to (6x + 5)^2-10 =-18x-15 in terms of m.
