Answer:
gives the solution 
.
gives the solution 
.
Step-by-step explanation:
I will solve both interpretations.
If we assume the equation is 
, then the following is the process:
Add 5 on both sides:
Simplify:
Now write an equivalent logarithm form:
Now using the change of base:
.
If we assume the equation is , then we use the following process:
Write an equivalent logarithm form:
Add 5 on both sides:
Use change of base formula:
Answer:
The image is (-18,0)
Step-by-step explanation:
Here, we want to find the image of the given point after dilation by the given scale factor
Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;
(kx , ky)
Applying this in the given scenario, we have
(2(-9) , 2(0))
= (-18,0)
What are u asking, the difference?
Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°
