Answer:

D. 9

Step-by-step explanation:

We have been given an equation and we are asked to find the solution for our given equation.

t(7-2)=9\cdot 7-9\cdot 2

Upon factoring out 9 from right side of our equation we will get,

t(7-2)=9(7-2)

t(5)=9(5)

5t=9*5

Upon dividing both sides of our equation by 5 we will get,

\frac{5t}{5}=\frac{9*5}{5}

x=9

Therefore, the solution to our given equation is 9 and option D is the correct choice.

What is the value of x in the equation x- 3/4 =5 1/6​
Wewaii [24]

Answer:

5 11/12

Step-by-step explanation:

First convert the mixed number into an improper fraction: 31/6

Find a common denominator:

18/24 and 124/24

124/24+ 18/24 is 142/24 and that is the same as 5 11/12

Hopefully this helps and you can have a lovely day!

How does the unit circle allow the trigonometric functions to be defined for all real numbers instead of just for acute angles?
Molodets [167]

Every point in the unit circle is identified either by its coordinates (x,y) or by the angle it forms with the x-axis, \alpha.

The trigonometric functions associate with every angle \alpha and the correspondant (x,y) coordinates the two values

\cos(\alpha)=x,\quad\sin(\alpha)=y

This procedure can be done for every angle \alpha, so you don't have to work with acute angles only.

How do the graphs of the functions f(x)=<img src="https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B2%7D%29%5Ex" id="TexFormula1" titl
grin007 [14]

Step-by-step explanation:

f(x) = (3/2)ˣ

g(x) = (2/3)ˣ

These are examples of exponential equations:

y = a bˣ

If b > 1, the equation is exponential growth.

If 0 < b < 1, the equation is exponential decay.

So f(x) is an example of exponential growth, and g(x) is an example of exponential decay.

Also, 2/3 is the inverse of 3/2, so:

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

So more specifically, f(x) and g(x) are reflections of each other across the y-axis.

Find the equation of the line that is perpendicular to 3y-x=7 and passes through the point (2,-1
boyakko [2]
Hello
<span>an equation for the line in​ point-slope form and general form is :
y = ax+b   a : </span>slope  ; the <span>Passing through (x' ; y')
</span>y' = ax'+b 
y-y' =a(x-x')      and : x' =2   y' = - 1
calculate a :
let :  y = ax+b .....(D)
   ....<span>3y-x=7</span>....(D') or  y = (1/3)x+7/3
.(D) perpendicular to(D') : slope (D) × slope (D') = -1 

 slope (D') = 1/3
slop(D)×(1/3) = -1
slope (D) = -3
equation for the line    :   y-y' =a(x-x') 
y+1 =(-3) (x-2)

Help with my homework <br> Evaluate the exponent expression for a = 1 and b = –2.
Snowcat [4.5K]

Answer:

  -1/16

Step-by-step explanation:

Put the values where the variables are and do the arithmetic.

1 to any power is 1, so you can ignore all of the 'a' factors. That leaves ...

  1/(2b^3) = 1/(2(-2)^3) = 1/(2(-8)) = -1/16

___

A calculator can help you figure this out.
