Answer:
h = 7, k = -1
Step-by-step explanation:
After 7 units left,
The function f(x) maps onto f(x+7)
g(x) = f(x + 7)
g(x) = 2(x + 7) - 1
g(x) = 2(x + h) + k
h = 7, k = -1
Answer: B) 6x - 6 = 15x + 15
Step-by-step explanation:
To find our answer, we need to first work out each equation.
A) 6x - 15 = 6x + 15
First, cancel out the equal terms.
6x - 6x - 15 = 15
-15 = 15
This statement is false.
B) 6x - 6 = 15x + 15
-9x = 21
x = -7/3
<u>This statement has one solution. </u>
C) 6x - 6 = 6x + 15
-6 = 15
This statement is false.
D) 6x + 15= 6x + 15
15 = 15
This statement has infine solutions.
1/12 should be the answer
Two angles are complementary when their sum is equal to 90°.
So, ( 2x + 39 ) + ( 7x - 21 ) = 90°
9x + 18° = 90°
x = 8°
Putting value of x in the angles given :
( 2x + 39 )° = 2(8°) + 39° = 55°.
( 7x - 21 )° = 7(8°) - 21° = 35°.
Therefore, the angles are 55° and 35°.
Hence, this is the required solution.
