Answer:
Try -6/7
Step-by-step explanation:
Do the lines given by the equations below intersect at the point (4,-6)? Explain why or why not.
2x - y = 14
x - 3y = 22
A. No, (4, -6) is not a point of intersection because it is not a solution to x - 3y = 22.
B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.
C. No, (4 ,-6) is not a point of intersection because it is not a solution to 2x - y = 14.
D. No, (4, -6) is not a point of intersection because it is not a solution to either equations.
Answer:
B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.
Step-by-step explanation:
In order to find if a certain point exists on a line or not, we can simply substitute in the values, and see if the result is valid. Here we are given the point (4,-6), this means our x=4 and our y=-6. If this point lies on a line, then substituting in the values should result in a valid equation. Let's try the first one:
2x-y=14
2(4)-(-6)=14
8+6=14
14=14
This equation is valid which means the point (4,-6) is indeed a point on the first given line equation.
Now for the second one:
x-3y=22
(4)-3(-6)=22
4+18=22
22=22
This is also a valid equation meaning the point (4,-6) also exists on the second line equation. Since this point exists on both lines, they will intersect each other on a graph. Therefore the best answer here is B. Yes, (4, -6) is a point of intersection because it is a solution to both equations.
Hope this helped!

Statement 4(6x+1) +4 =104 reason ?
Answer:
x = 4
Step-by-step explanation:
4(6x+1) +4 =104
-4 -4
4(6x+1) = 100
distribute
24x + 4 = 100
-4 -4
24x = 96
x = 4
To check your work, substitute the x value into the equation.
4(6(4)+1) +4 =104
4(25) + 4 = 104
104 = 104
It is correct, one solution.

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

17. A golfer takes a swing from a hill twenty feet above the cup
with an initial upwards velocity of 32 feet per second. How
long does it take the ball to land on the ground near the cup?
Answer:
The height as a function of time is
h(t) = -(1/2)gt2 + v0t + h0
h(t) = -16t2 + 32t + 20
The ball reaches the ground when h(t) = 0
-16t2 + 32t + 20 = 0
Solve this quadratic equation for t. You will get a positive solution and a negative solution. Discard the negative solution, since time begins at t=0 at the moment the ball is struck. Can you finish from here?
What is the equation of the line?
A. y=2x+2
B. y=2x-4 C.
y=1/2x+2
D. y=1/2x-4
Answer:
The equation for the line that is shown is: Answer choice C.
[tex]y =\frac{1}{2}x+2[/tex]
Step-by-step explanation:
From what I can see, there is several clues that can lead us to our answer by just looking at the graph:
y - interceptWhether if the slope is positive or negativeA. Your y - intercept is where your line crosses at a point on the y - axis, so your y - intercept is:
y - intercept = 2If you do not know, the y - intercept form in slope - intercept form is the 'b' value:
[tex]y = mx + b[/tex]
[tex]b =[/tex] y - intercept
[tex]mx =[/tex] slope (m is actually the letter that represents it, but thought I might include x in it to show you from the formula)
Now that you have found your 'b' value, you can eliminate several answer choices: Answer choice B. and D.
B. Now we will see if the slope is positive or negative.
To find out whether it is positive or negative, we would have to take a look at the direction of the line, in this case, the line is going upwards to the right, meaning the slope is positive.
C. Now to find the slope:
To do this we must know the fraction like form of a slope, this would be:
(m = slope)
To determine the slope, m, it is [tex]\frac{RISE}{RUN}[/tex]
'Rise' meaning the y point and 'run' being the x point
In this case:
the line rises up 1 and runs over 2
so, m = [tex]\frac{1}{2}[/tex]
Your final answer will be:
[tex]y =\frac{1}{2}x+2[/tex]

Clara has 8 sponsors for the charity walk. Upton has 12 sponsors. Which statement comparing the number of sponsors Clara and Upton each have is accurate?
Clara has 4 times as many sponsors as Upton.
Clara has 4 more sponsors than Upton.
Upton has 4 times as many sponsors as Clara.
Upton has 4 more sponsors than Clara.
Upton has 4 more sponsors than Clara.
If Upton has 12 sponsors and Clara has 8, Clara cannot have more than Upton so times is not an option. Upton only has 4 more and not times than Clara.

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]
