Answer:
Option 3: take base-4 log each side
In case of multiple answers:
Options 3,4 & 5
Step-by-step explanation:
4^(x+3) = 18
Apply log4 both sides to being the power down
You can take log with any other base too.
In case of multiple answers, options 4 and 5 are also valid

Answer:

Step-by-step explanation:
First create an equation in slope-intercept form, y = mx + b. To do this, find the rate of change or slope (m), and the y-intercept (b).
Using two pairs, (-7, -3) and (-8, -4),

m = 1
To find b, substitute m = 1, x = -7 and y = -3 into y = mx + b.
Thus:
-3 = (1)(-7) + b
-3 = -7 + b
-3 + 7 = b
4 = b
b = 4.
Replace y with f(x), m with 1 and b with 4 in y = mx + b.
The function would be:

Answer:
SSS similarity
Step-by-step explanation:
From the smaller triangle to the larger triangle, the ratio of each pair of corresponding sides is 2.
Since you don't have the picture, I can explain how to do the problem. Then, you can select the correct answer.
To find the area of a parallelogram, you must multiply the base times the height. If you have those 2 values, just multiply them and you will be done.
