It is simple 3.4, 4.3, 4.7, 7.4
Answer:x=17
Step-by-step explanation:
B. infinitely many solutions
Answer:
The base of the exponential function is 0.5 which is between 0 and 1 and thus this is an exponential decay function.
Step-by-step explanation:
Exponential equations are usually in the form;

where;
a is the initial value, that is the value of y when x is 0,
b is the growth or decay factor and also the base of the exponential function
If b>1, then it is an exponential growth function and the values of y keep getting bigger.
if 0<b<1, then it is an exponential decay function and the y values keep getting smaller as x increases.
In the function given;

The base of the exponential function is 0.5 which is between 0 and 1 and thus this is an exponential decay function.
In order to justify our prediction, we can simply obtain the graph of the function and check on how x and y vary.
From the attachment below we can see that the values of y become increasingly smaller as the values of x increases in magnitude which justifies our predictions.
I believe your answer is -220w-22
2-3(2w+1)=7w-3(7+w)
+7w -7w
2-3(9w+1)=-3(7+w)
+w -w
2-3(10w+1)=-3(7)
2-3(10w+1)=-21
-1(10w+1=-21
-21 +21
-22(10w+1)
-220w-22
