Answer:
Step-by-step explanation:
a) 8.23 x 10^5 move the decimal over 5 places, 319000000 is 319 million move the decimal over until there is one number on the left side --> 3.19 x 10^8
b) 3.19 x 10^8 / 8.23 x 10^5 = 387.61 roughly 388 times larger
Answer:
70
Step-by-step explanation:
The simplest way to find the number is work backwards. If you know the final answer is 10, start with 10 and make the number x. Then set up the original equation.
0.5x-25=10
Then start working backwards(isolate).
0.5x-25=10
+25 +25
in other words, 10+25=0.5x. (the 25 cancels out because -25+25=0)
10+25=35, so 35=0.5x.
Now, instead of dividing by 2, multiply by 2(opposite again).
35=0.5x
/0.5(aka *2) /0.5(cancels out)
now you are left with 70=x, so the number is 70.
Answer:
Step-by-step explanation:
Step1:-
Given 4 b+5=t
subtracting on both sides with 5 we get
After simplification 
Dividing '4' on both sides , we get and simplification
now Final answer 
This is the answer. I hope it helps you out!!!
Answer:
a. Graph 1 is y=2^x and Graph 2 is y=2x+1
b. The slope increases over time on Graph 1, and remains the same on Graph 2
c. Graph 1 is exponential (y=2^x) and Graph 2 is linear (y=mx+b)
Hope this helps!
Step-by-step explanation:
a: y=2* is exponential, so it is graph 1 (it makes a curve) y=2x+1 is linear (makes a line), and it has a slope of 2 and a y-intercept of 1, so y=2x+1 is graph 2!
b. slopes of Exponential Functions usually continue to increase (unless the number that is being affected by the exponent x is less than 1, in which they would continue to decrease), and linear functions have a set slope (m in y=mx+b)
c. Explanation is in the answer (it says to explain)
