Answer:
Step-by-step explanation:
x+y>0, x>0, when y=0
x+y<-5 x<-5 when y=0
since the sign is only< then it is dotted line, and since one is greater and is less than they actually do not intersect
Answer:
b
-28/9
Step-by-step explanation:
5+9b-23
5+9b=-23
9b=-28
b=-28/9
Generic exponential growth model: y = Ao[1+r]^t
In this case: r = 3.5% = 0.035
y = 2Ao .....[the double of the initial value]
Then: 2Ao =Ao (1 + 0.035)^t
(1.035)^t =2
Take logarithm to both sides
t ln(1.035) = ln(2)
t = ln(2) / ln(1.035) = 0.693 / 0.0344 = 20.15
Answer: 20.15 hours.
Answer:
3/4.
Step-by-step explanation:
36 and 48 have a common factor of 12.
(36 / 12) / (48 / 12)
= 3/4 (answer).
To solve problem #1 follow the steps below...
Step 1:Think back to PEMDAS
P=Parentheses
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction
(Think of M,D as brothers and whichever once comes first in the problem you do.This rule also applies to A,S)
Step 2: Look back to your problem
(6 divided by 2 plus 1) plus 10x2
Step 3: Start with the parentheses
6 divided by 2 plus 1
Step 4: Do the division first
6 divided by 2=3
Step 5:Now the addition
3 plus 1=4
Step 6: Rewrite the problem
4 plus 10x2
Step 7: Do the multiplication
10x2=20
Step 8: Rewrite your problem again
4 plus 20
Step 9: Solve
4 plus 20=24
Step 10: Look back at your work and see what order your operations were done in
.Division
.Addition
.Multiplication
.Addition
Step 11: Compare your order to the choices
Answer: b
