Answer:
x=15/16
Step-by-step explanation:
Let's solve your equation step-by-step.
6−34x+13=12x+5
6+−34x+13=12x+5
Multiply all terms by x and cancel:
6x+−34+1x3=12+5x
193x+−34=5x+12(Simplify both sides of the equation)
193x+−34−5x=5x+12−5x(Subtract 5x from both sides)
43x+−34=12
43x+−34+34=12+34(Add 3/4 to both sides)
43x=54
(34)*(43x)=(34)*(54)(Multiply both sides by 3/4)
x=1516
Check answers. (Plug them in to make sure they work.)
x=1516(Works in original equation)

What is the equation of a line perpendicular to y=1/4x−3 and passes through the point (−2, 4)?
Answer:
y = -4x - 4Step-by-step explanation:
Given line
y = 1/4x - 3Perpendicular line has a slope that is negative reciprocal to a given
y = - 4x + b is the equation,Finding the value of b using the point (-2, 4)
4 = -4*(-2) + b4 = 8 + bb = -4So the line is:
y = -4x - 4Answer:
y = -4x - 4
Step-by-step explanation:
The line of a perpendicular line is the opposite reciprocal of the original line.
1/4 -> -4/1 -> -4
Now that we have the new slope, we can find the new y-intercept.
y = -4x + b
4 = -4(-2) + b
4 = 8 + b
-4 = b
y = -4x - 4

$13.00
$14.79
$16.55
$19.80
$20.25
$21.50
Answer:
Total amount spent for meal = $16.65
Step-by-step explanation:
Given:
Amount spent on dinner = $20
Tip = 20%
Find:
Total amount spent for meal
Computation:
Total amount spent for meal = Amount spent on dinner / (1+tip)
Total amount spent for meal = 20 / 1.2
Total amount spent for meal = 16.666
Total amount spent for meal = $16.65

6. A tank contains 100-gallon of pure water. At time t = 0, a solution containing 2 lb of salt per gallon flows into the tank at a rate of 3 gallons per minute, and the well-stirred mixture flows out at a rate of 4 gallons per minute. Find the amount (in lb) of salt Q in the solution as a function of t in minutes.
Answer:
The answer is below
Step-by-step explanation:
Let Q represent the amount of salt in the tank at time t.
[tex]\frac{dQ}{dt}= flow\ in - flow\ out\\ \\flow\ in=3\ gal/min*2\ lb/gal=6\ lb/min\\\\net\ gain\ in\ tank\ volume=3-4=-1, henceflow\ out= \frac{4Q}{100-t} \\\\\frac{dQ}{dt}= 6-\frac{4Q}{100-t} \\\\\frac{dQ}{dt}+ \frac{4Q}{100-t}=6\\\\The \ integrating\ factor\ is:\\\\IF=e^{\int\limits {\frac{4}{100-t} } \, dt }=e^{-4\int\limits {\frac{-1}{100-t}}=e^{-4ln(100-t)}=(100-t)^{-4}}\\\\Multiplying\ through \ by\ IF: \\\\(100-t)^{-4}\frac{dQ}{dt}+ (100-t)^{-4}\frac{4Q}{100-t}=6(100-t)^{-4}\\\\[/tex]

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $155 for 100 minutes of usage and $245 for 200 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x? (1 point)
A.Draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 0.9
B.Draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 1.1
C.Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 1.1
D.Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9
Answer:
The answer is A.Draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 0.9

4) whole
Which of the following expressions is correct?
-(-21) = 21
-(-21) = -21
-(21) = 21
(-21) = 21
Answer:
The correct answer is: [A]: " -(-21) = 21 " .
________________________________
Step-by-step explanation:
________________________________
Let us examine the answer choices given.
________________________________
Choice: [A]: " -(-21) = 21 . This is correct;
→ since a "negative value of negative value" is a "positive value" ; as shown in this case. The equal sign holds true, since the
"negative of a "negative value" is equal to the "positive value" of that same "positive value equivalent."
________________________________
Choice: [B]: " -(-21) = -21 . This is incorrect. As explained above:
→ a "negative of negative" is a "positive value" .
This answer choice shows that a "negative of negative"; is a "negative" :
→ which is: INCORRECT.
→ Rule out: "Choice: [B]."
________________________________
Choice: [C]: " -(21) = 21 . This is incorrect. The "negative" value [of a positive integer is not equal to the "equivalent positive value" of that same integer.
→ Rule out: "Choice: [C]."
________________________________
Choice: [D]: " (-21) = 21 "; This is incorrect. In a conceptually similar way as explained above—(for "Answer Choice: [C]" — the "negative value equivalent" of an integer is NOT equal to the "equivalent positive value" [of that same integer.].
→ Rule out: "Choice: [D]."

The correct answer is: [A]: " -(-21) = 21 " .
