Answer:
no real numbers will make this equation true
Step-by-step explanation:
if you square both sides, you'll get sqrt(-49). this will get you an imaginary number (7i) which is not a real number.

what is the resistance of a circuit if it has a voltage of 50v and a current of 8 ? and show me the calculations
Answer:
25/4 ohm
Step-by-step explanation:
Use Ohm‘s Law: V=IR which stands for Voltage = Electric Current * Resistance.
Plug in your given values: 50 = 8R. R = 25/4 ohm.
What is the answer to 0=V+19
Answer:
v= -19
Step-by-step explanation:
Solve for V by simplifying both sides of the equation, then isolating the variable.
Answer:
-19
Step-by-step explanation:
+19 -19 = 0
Therefore,
V = -19
Subtract 19 from both sides 0 - 19 = -19,
-19 = V

Answer:
z = 47 at (x, y) = (3, 8)
Step-by-step explanation:
In the attached graph, the inequalities are graphed as their opposites, so the feasible solution region is the white area of the graph. The dashed boundary lines are part of the feasible region. The vertex of the feasible region that is farthest from the origin is ...
(x, y) = (3, 8)
The value of z there is 5·3 +4·8 = 47.
The maximum value of z is 47 at the point (x, y) = (3, 8).

For which equation is b = 5 not the solution?
options:
1. 8 - b = 13
2. b + 6 = 11
3. b + 4 = 9
4. 12 - b = 7
Answer:
option 2 and 3
b+6=11
b+4=9
Answer:
1. 8 - b = 13
Step-by-step explanation:
It says for which equation is b = 5 not the solution.
So, we need to plug in 5 into every b, and find out which one is incorrect.
1. 8 - 5 = 13 (incorrect)
2. 5 + 6 (correct)
3. 5 + 4 = 9 (correct)
4. 12 - 5 = 7 (correct)
Therefore, option 1 is the answer to your question.
solve x 9/× = x/4 what is x
Answer:

Since the entire line is 60 and MN is five times as long. Then I would say that you could just divide 60 by 1/5 or 0.2
since the length of the line is 60 you gots to fos and divide it my homie.
60/5=12 so thats means the length is 12

the thief with the stolen accordion has been traveling on a raft for 2 hour 40 minutes from Village Ivanovo toward Village Sosnovka. Aniskin immediately leaves Sosnovka in a motorboat and travels upstream toward the raft. Aniskin catches the thief 27 km from Sosnovka. Find the speed of the raft if the speed of the motorboat in still water is 12 km/h and the distance from Ivanovo to Sosnovka is 44 km.
Answer:
3 km/hStep-by-step explanation:
Let the speed of raft (current) - rSpeed of motorboat - 12 km/hThe distance between villages - 44 kmLet the time spent by Aniskin - tThe time the thief was in travel = 2 hr 40 min + t = 2 40/60 + t = 3/8 + tThe distance the thief traveled = 44 - 27 = 17 kmWe have following equations:
r(8/3 + t) = 17(12 - r)t = 27Simplify the equations:
r(8/3 + t) = 17 ⇒ rt + 8/3r = 17(12 - r)t = 27 ⇒ 12t - rt = 27Add up the equations and solve for r:
rt + 8/3r + 12t - rt = 448/3r + 12t = 44r = 16.5 - 4.5tSubstitute r into second equation:
(12 - 16.5 + 4.5t)t = 274.5t² - 4.5t = 279t² - 9t - 54 = 0Solving we get
t = 3 hFind r:
r = 16.5 - 4.5*3 = 3 km/hAnswer:

= 4.75 × b
38 = 4.75b
b = 38 ÷ 4.75
b = 8

Consider the following graph.
The x y coordinate plane is given. The curve begins at (0, 5) goes down and right becoming less steep, changes direction at (1, 2) goes up and right becoming more steep, goes through the approximate point (2, 3.1), goes up and right becoming less steep, changes directions at (3, 4), goes down and right becoming more steep, sharply changes direction at (4, 1), goes up and right becoming less steep passing through the approximate point (5, 4.2) and ends at (6, 6).

a)Function is increasing in intervals (1,3) and (4,6).
b)Function is decreasing in intervals (0,1) and (3,4).
c)Graph is concave upward in the interval (0,2) and (3,5).
d)Graph is concave downward in the interval (3,4).
e)Points of inflection are x=3 and x=5.
Let us make the graph of the given function. In the graph, We have connected points linearly, please consider it as a curve.
What is the point of inflection?The point of inflection or inflection point is a point in which the concavity of the function changes.
Therefore, From the attached graph, we can see that:
a)Function is increasing in intervals (1,3) and (4,6).
b)Function is decreasing in intervals (0,1) and (3,4).
c)Graph is concave upward in the interval (0,2) and (3,5).
