So answer is C.
Hmm first I'll check the slanted line cutting 2nd quardrant..
some points on this line are (-3,0),(0,3),(2,5),(3,6),etc.
Testing (-3,0)=(x,y):
y=-3+3=0 (true)..comparable with y=x+3
Testing (2,5)=(x,y):
y=2+3=5 (true)..comparable with y=x+3
Since this line bounds the value within some limits less than or equal to x+3(see graph you can see it clearly)...so it can be represented by y<=x+3.
Similarly for next line cutting 1st and 4th quardrant,
Points: (0,-4),(1,-1),(2,2),etc..
Testing (0,-4)=(x,y):
y=3*0-4=-4(true)...comparable with y=3x-4
Testing (1,-1)=(x,y):
y=3*1-4=-1(true)...comparable with y=3x-4
This line bounds within the region y>3x-4
NOTE:
1)If the region is bounded by solid line(line without dot) then you write inequality as y<=something or y>= something.
2)If the region is bounded by dotted line(line withdot) then you write inequality as y<something or y> something.
Hope this helps!
Using substitution method, the system of linear equations has no solution.
To determine the solution to the system of equations, we can use substitution method;
4x - 5y = 5 ...eq(i)
-0.08x + 0.10y = 0.10 ...eq(ii)
From equation (i)
4x - 5y = 5
let's make x the subject of formula;
4x = 5 + 5y
x = (5 + 5y) / 4 ...eq(iii)
Put eq(iii) into equ(ii)
-0.08[(5 + 5y)/4] + 0.10y = 0.10
(-2/5 - 2/5y)/4 + 0.10y = 0.10
y = no solution
Since y has no solution, this implies that the system of linear equations has no solution.

Answer:
The answer to your question is 12
Step-by-step explanation:
Use proportion to solve this problem
Equation
Substitution
25x = 15(20)
25x = 300
x = 300 / 25
x = 12
x = JH = 12
Answer:
the correct answer is option A. 12
Answer:
600
Step-by-step explanation:
Given parameters:
Number that rode in columns = times the number that rode in rows.
2200 rode in columns
Unknown:
Number of people that rode in rows = ?
Solution:
Let the number of people that rode in columns = C
Let the number of people that rode in rows = R
C = R
Number of people that rode in rows = 2200;
2200 = R
11R = 2200 x 3
R =
R = 200 x 3
R = 600
Number of people that rode in rows = 600
Answer:
The answer is x=2
Step-by-step explanation:
Given function is :
2In4x= 2In8
Solving this we get,
ln = ln64
Now using n ln m = ln and doing further step we get
This gives :
