On the number line, a point was moved from -7 to -3. Which of the following problems describes this move?
-7 + 4 = -3
-7 + 3 = -4
-7 - 3 = -10
-7 - 4 = -3
Answer:
-7+4=-3
Step-by-step explanation:
Think of it as adding head to cold (cold being negative numbers). You are adding four "heats" to seven which makes it hotter. The hotter something gets the closer to positive numbers it is. . . so when adding four things if heat to 7 it gets hotter by four therefore it's now at -3.
sorry if that didn't make sense
Answer & Step-by-step explanation:
To start the question, you could set up an equation to explain that -7 is being moved x units to -3
-7 + x = -3
Next you have to find x
-7 + x - (-7) = -3 - (-7)
x = 4
Now you substitute x for 4 in the original equation
-7 + 4 = -3

Find the complex zeros of the following polynomial tunction and use the complex zeros to factor f
f(x)= x^3-15x^2+79x-145
Answer:
x = 5 or x = 5 + 2 i or x = 5 - 2 i
Step-by-step explanation:
Solve for x:
x^3 - 15 x^2 + 79 x - 145 = 0
Hint: | Factor the left-hand side.
The left hand side factors into a product with two terms:
(x - 5) (x^2 - 10 x + 29) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 5 = 0 or x^2 - 10 x + 29 = 0
Hint: | Look at the first equation: Solve for x.
Add 5 to both sides:
x = 5 or x^2 - 10 x + 29 = 0
Hint: | Look at the second equation: Solve the quadratic equation by completing the square.
Subtract 29 from both sides:
x = 5 or x^2 - 10 x = -29
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25 to both sides:
x = 5 or x^2 - 10 x + 25 = -4
Hint: | Factor the left-hand side.
Write the left hand side as a square:
x = 5 or (x - 5)^2 = -4
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
x = 5 or x - 5 = 2 i or x - 5 = -2 i
Hint: | Look at the second equation: Solve for x.
Add 5 to both sides:
x = 5 or x = 5 + 2 i or x - 5 = -2 i
Hint: | Look at the third equation: Solve for x.
Add 5 to both sides:
Answer: x = 5 or x = 5 + 2 i or x = 5 - 2 i

50 cents per minute to dollars per hour
Unit conversion is a way of converting some common units into another without changing their real value. 50 cents per minute to dollars per hour is 3 dollars per hour.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
The 50 cents per minute can be converted to dollars per hour as,
50 cents per minute
= 50 cents / 1 minute
Since 1 dollar has 100 cents and 1 hour has 60 minutes, therefore,
= (50/100)dollar / (1/60) hour
= (50×60)/100 dollars per hour
= 3,000/100 dollars per hour
= 3 dollars per hour
Hence, 50 cents per minute to dollars per hour is 3 dollars per hour.

The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70?
Answer:
y = 17.5
Step-by-step explanation:
Use the direct proportion equation, y = kx
Plug in the x and y values to solve for k
y = kx
35 = k(140)
0.25 = k
Then, plug in the k value and given x value into the equation, and solve for y
y = kx
y = 0.25(70)
y = 17.5

Two pools are being drained. To start, the first pool had 3850 liters of water and the second pool had 4370 liters of water. Water is being drained from the first pool at a rate of 33 liters per minute. Water is being drained from the second pool at a rate of 43 liters per minute. Let x be the number of minutes water has been drained. (a) For each pool, write an expression for the amount of water in the pool after x minutes.
Amount of water in the first pool (in liters) =
Amount of water in the second pool (in liters) =
(b) Write an equation to show when the two pools would have the same amount of water.
Answer:
(a)
Amount of water in the first pool (in liters) = 3850 liters - 33 liters per minute * x minutes
Amount of water in the second pool (in liters) = 4370 liters - 43 liters per minute * x minutes
(b)
3850 liters - 33 liters per minute * x minutes= 4370 liters - 43 liters per minute * x minutes
Step-by-step explanation:
(a) With x being the minutes after which you want to calculate the amount of water in the pool, to calculate this amount of water you must subtract the water drained from the initial amount of water that the pool contains.
Knowing that, for example, the water from the first pool drains at a rate of 33 liters per minute, then after x minutes, the total water drained will be 33 liters per minute * x minutes. Then:
Amount of water in the first pool (in liters) = 3850 liters - 33 liters per minute * x minutes
Reasoning in the same way:
Amount of water in the second pool (in liters) = 4370 liters - 43 liters per minute * x minutes
(b) Now want to know when the two pools would have the same amount of water. If they have the same amount of water then you can express:
Amount of water in the first pool = Amount of water in the second pool
Replacing the expressions found in (a):
3850 liters - 33 liters per minute * x minutes= 4370 liters - 43 liters per minute * x minutes

Answer:
[tex]\displaystyle y=\frac{1}{2}x-2[/tex]
Step-by-step explanation:
The equation of the line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (-6,-5) and (-4,-4), thus:
[tex]\displaystyle m=\frac{-4+5}{-4+6}=\frac{1}{2}[/tex]
Knowing the value of the slope, the equation of the line is:
[tex]\displaystyle y=\frac{1}{2}x+b[/tex]
The value of b can be found using any of the points in the equation and solving for b. Let's pick the point (-6,-5):
[tex]\displaystyle -5=\frac{1}{2}(-6)+b[/tex]
Operating:
-5=-3+b
Solving:
b=-2
The equation of the line is:
[tex]\boxed{\displaystyle y=\frac{1}{2}x-2}[/tex]

300

0.5 1.5 2.5 3.5 4.5 5.5 6.5
Time (hours)
Answer:
It takes 2.4 hours to travel 480 miles.
Step-by-step explanation:
From the graph race car is moving at 100 miles in 0.5 hours. So, in 1 hour, car could travel 2*100 =200 miles per hour.
So, we can set up equation as
y= 200x.
Plug in y as 480 then solve for x.
480 =200x
Divide both sides by 200
2.4=x
So, it would take 2.4 hours.
