Did you get this answer???!
Answer:
Dotted linear inequality shaded above passes through (0, 4) and (4, 0). Solid exponential inequality shaded below passes through (negative 2,2) & (0,5)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area above the dotted line 
The dotted line passes through the points (0,4) and (4,0) (y and x-intercepts)
and
-----> inequality B
The solution of the inequality B is the shaded area above the solid line 
The solid line passes through the points (0,5) and (-2,2)
therefore
The solution of the system of inequalities is the shaded area between the dotted line and the solid line
see the attached figure
Dotted linear inequality shaded above passes through (0, 4) and (4, 0). Solid exponential inequality shaded below passes through (negative 2,2) & (0,5)
No it is not because its more then ten numbers away from the solution of the five tickets
Answer:
2f =c
350c + 500f = 4800
Step-by-step explanation:
Twice as many cans of soup as frozen dinners
All food combined contain 4800 (mg of sodium)
2f =c
350c + 500f = 4800
These are the systems of equations.
Answer:
<em>It takes them 1.875 hours.</em>
<em></em>
<em>Step-by-step explanation:</em>
<em></em>
<em>Here, the job is cleaning the house.</em>
<em></em>
<em>Mom does 1 job in 3 hours.</em>
<em></em>
<em>In 1 hour, mom does 1/3 of the job.</em>
<em></em>
<em>Dad does 1 job in 5 hours.</em>
<em></em>
<em>In 1 hour, dad does 1/5 of the job.</em>
<em></em>
<em>Mom and dad working together do the job in x hours.</em>
<em></em>
<em>In 1 hour, mom and dad together do 1/x of the job.</em>
<em></em>
<em>1/3 + 1/5 = 1/x</em>
<em></em>
<em>5/15 + 3/15 = 1/x</em>
<em></em>
<em>8/15 = 1/x</em>
<em></em>
<em>8x = 15</em>
<em></em>
<em>x = 15/8 = 1.875</em>
<em></em>
<em>Answer: It takes them 1.875 hours.</em>
