Answer:
The Y intercept doesn't exist, and the slope is undefined
Step-by-step explanation:
The graph provided for us is a vertical line. x= 7
this means the line will go up and down forever without a slant because x will always equal 7.
Ex:
X | Y
7 | -3
7 | -2
7 | -1
7 | 0
7 | 1
7 | 2
7 | 3
Answer:
106
Step-by-step explanation:
Apply PEMDAS:
In this scenario we will solve the exponent part first, followed by the multiplication part and then we add them up.
Hope this helps!
ANSWER
EXPLANATION
Method 1
Vertically opposite angles are equal, therefore
This implies that,
We simplify to get,
Dividing through by 3 gives,
Also,
This implies that,
We simplify the right hand side to get,
We divide both sides both sides by 2 to get,
Method 2
Angles on straight line sums to 180°.
This implies that,
Also,
One method to solve is to rewrite 9 as a power of 3 and then equate exponents to solve for x
3^x = 9^(x+2)
3^x = (3^2)^(x+2)
3^x = 3^(2(x+2))
x = 2(x+2) <<-- bases are equal, so exponents must be equal
x = 2x+4
x-2x = 4
-x = 4
x = -4
Answer: x = -4
