Answer:

Step-by-step explanation:
2x + 17.6 = 6
Subtracting both sides by 17.6
2x = 6 - 17.6
2x = -11.6
Dividing both sides by 2
x = -11.6 / 2
x = -5.8
Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
Answer:
9
Step-by-step explanation:
The denominator of a fraction is always the bottom number, while the top number is always the numerator.
Answer:
y = 2/3x
Step-by-step explanation:
3x + 2y = 6
2y = 6 - 3x
y = 3 - 3x/2 or y = - 3/2x + 3
- - - - - - - - - - - - - -
Then find the negative reciprocal of the slope of the original line.
y = 2/3x
Given:
The graph of an exponential function.
To find:
The function in the form of
.
Solution:
The general form of an exponential function is
...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,



For x=1 and f(x)=7,

Putting a=4, we get


Substitute a=4 and
in (i).

Therefore, the required exponential function is
.
