y=2x+6
y = 2x-1
Solve for X and Y
Answer:
no solution
Step-by-step explanation:
y = 2x + 6 → (1)
y = 2x - 1 → (2)
substitute y = 2x + 6 into (2)
2x + 6 = 2x - 1 ( subtract 6 from both sides )
2x = 2x - 7 ( subtract 2x from both sides )

Alicia watched a drone take off from a bridge. The height of the drone (in meters above the ground)minutes after takeoff is modeled byh(t) = −3+^2 + 12t +96Alicia wants to know when the drone will land on the ground.1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number inthe equation.h(t) =2) How many minutes after takeoff does the drone land on the ground?
a.
Function:
[tex]h(t)=-3t^2+12t+96[/tex]Factoring -3, we have:
[tex]\begin{gathered} h(t)=-3t^2+12t+96 \\ h(t)=-3(t^2-4t-32) \end{gathered}[/tex]Middle term facotizing the term inside parenthesis:
[tex]\begin{gathered} h(t)=-3(t^2-4t-32) \\ h(t)=-3(t-8)(t+4) \end{gathered}[/tex]This is the factored form.
b.
h(t) is the height.
When it lands on the ground, the height (h(t)) is 0, so we have:
[tex]\begin{gathered} h(t)=-3(t-8)(t+4) \\ 0=-3(t-8)(t+4) \end{gathered}[/tex]If we solve this equation for t, we get the line drone lands on the ground.
Let's do this:
[tex]\begin{gathered} -3(t-8)(t+4)=0 \\ t=8,-4 \end{gathered}[/tex]Time can't be negative, so the solution is t = 8 seconds.

How do you find the distance between the points shown
Answer:
A. Subtract the distance between each point and the x-axis.
Step-by-step explanation:
The points shown are horizontally distanced. Because of this, you need to subtract their x values. In coordinate planes, the variable "x" represents how far a point is or is not from the origin. Given this information, you need to subtract the x values to get the distance they are apart. Note: Distance on a number line or graph is always given in absolute value. Absolute value is the term for when a number is converted to its positive form. For instance, |-1| has these brackets around it representing absolute value. Whenever a number in absolute value is a negative number or is greater than 0, it will become its positive form. |-1| = 1
Hope this helps!
Option A is correct, By subtracting the distance between each point and the x axis we find the distance between the points shown
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
The given two points in the given graph are A(-8, -4) and B(2,-4)
Now let us plug in these points in the formula.
x₂= 2, x₁ = -8, y₂=-4, y₁=-4
Distance=√(x₂-x₁)²+(y₂-y₁)²
=√(2+8)²+(-4+4)²
=√(10)²
=10 units.
By subtracting the distance between each point and the x axis we can find the distance.
Hence, Option A is correct, By subtracting the distance between each point and the x axis we find the distance between the points shown

The centrifugal force of an object moving in a circle varies jointly with the radius of the circular path and the mass of the object and inversely as the square of the time, it takes to move about one full circle. A 6-gram object moving in a circle with a radius of 75 centimeters at a rate of 1 revolution every 3 seconds has a centrifugal force of 5000 dynes. Find the centrifugal force of a 20-gram object moving in a circle with radius of 155 centimeters at a rate of 1 revolution every 5 seconds.
Write down the equation.
Answer: 12,500
Formula for centrifugal force = [tex]\frac{k r m}{t^{2} }[/tex]
In the first case,
The mass of an object moving in a circle as 'm1' and radius as 'r1', 'k' as constant, and time as 't1'. 'f1' is centrifugal force.
centrifugal force is f1 = [tex]\frac{kr1m1}{t1^{2} }[/tex]
In the second case,
The mass of an object moving in a circle as 'm2' and radius as 'r2', 'k' as constant, and time as 't2'. 'f2' is centrifugal force.
m1 = 6 gram , r1 = 75 cm , t1 = 3 sec, f1 = 5000 dynes
as per equation, 5000 = [tex]\frac{ k * 75 * 6}{3^{2} }[/tex] , after calculation the value of k = 100
in the second case use the same equation and find centrifugal force (f2)
f2 = [tex]\frac{k * r2 * m2}{t2^{2} }[/tex] ,m2 = 20 gram , r1 = 155cm , t1 = 5 sec, k= 100
f2 = [tex]\frac{100 * 155 * 20}{5^{2} }[/tex] after calculation f2 = 12,400.
so, the final centrifugal force is 12,400 dynes.

Find the slope of the line that contains the following points: (17, -12) and (7, 8)
Answer: -2
Step-by-step explanation:
To find the slope of a line, we use the formula [tex]\frac{y(2)-y(1)}{x(2)-x(1)}[/tex]
{x(2),y(2)} coordinates of second points in line
{x(1),y(1)} coordinates of first points in line
So to solve, you take any set of your coordinates given and you chose one to be your second set and your first set. Then you take the y from your 1st set, and you subtract it from the y from your 2nd set. Then you take that and you put it over from what you get when you take the x from the 1st set, and you subtract that from the x in your 2nd set.
So when I solve using this the coordinates given, I get -12-8/17-7
This equals to -20/10, and that equals to -2.
So you find the slope of the line as -2

Corie buys dog food in a 34-pound bag. Her dog eats about 1 pound a day. Corie buys cat
food in a 16-pound bag. Her cat eats about 1/4 pound a day. Assume she buys new bags of pet
food on the same day. On which day will the two bags have the same weight? Show how you
figured it out.
The day the two bags will have the same weight is the 24th day.
On which day will the two bags have the same weight?The linear equation that can be used to determine the pound of dog food left is:
Amount of dog food left = capacity of the bag - (number of days x amount the dog eats per day)
Amount of dog food left = 34 - (1 x p)
Amount of dog food left = 34 - 1p
The linear equation that can be used to determine the pound of cat food left is:
Amount of cat food left = capacity of the bag - (number of days x amount the cat eats per day)
Amount of cat food left = 16 - (1/4 x p)
Amount of cat food left = 16 - 1/4p
On the day the two bags will have the same weight, the two above equations would be equal:
16 - 1/4p = 34 - 1p
p - 1/4p = 34 - 16
3/4p = 18
p = (18 x 4) / 3
p = 24 days

Amelia is saving up to buy a new $105 iPad pen. Her best friend gave her $12 and she saves $20 per week from her babysitting job. How many weeks will she have to save money in order to buy the iPad? Write an inequality to solve.
EXPLANATION
Let's see the facts:
Ipad pen cost = -$105
Best friend ----> +$12
---------------
-$93
Babysitting Saves +$20/week
We are still needing $93 dollars to buy the pen, so, if she earns $20 peer week, then she should work:
$93 = 20 $/week * number of weeks
Calling x to the number of weeks and turning this into an inequality:
12 + 20x ≥ 105
Subtracting -12 to both sides:
20x ≥ 105-12
Simplifying:
20x ≥ 93
Dividing both sides by 20:
x ≥ 93/20
Simplifying:
x ≥ 4.65
Answer: Amelia should at least work 5 weeks in order to save the money to buy the Ipad pen.

What is unitary method?The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. A single or distinct unit is referred to by the word unitary. Therefore, the goal of this method is to establish values in relation to a single unit. The unitary method, for instance, can be used to calculate how many kilometers a car will travel on one litre of gas if it travels 44 km on two litres of fuel. The unitary method involves calculating the value of a single unit, from which we can calculate the values of the necessary number of units.
Here,
cost of 2 pound of orange=$3
cost of 5 pound of orange=$7.50
cost of 3 pound of orange=$4.50
Therefore,
The cost of 1 pound of orange is $1.5
The total payment made=$7.50+$4.50+$3
=$15
The total weight of oranges=2+3+5
=10 pounds
One pound of oranges will cost $1.5. $15 was paid in total. Orange weighed ten pounds in total.

1100 children and 1900 adults attended the local zoo on that day.
A system of equations or an equation system is a finite set of equations for which common solutions are sought.
Given:
A local zoo's admission fee is $1.50 for children and $4.00 for adults.
On a certain day, 3000 people enter the zoo and $9250.00 is collected.
We have to determine how many children and how many adults attended?
Solution:
Let number of children enter the zoo = x
Then number of adults enter the zoo = 3000-x
Total collection = $9250
Collection from children + Collection from adults = 9250
1.50 × x + 4(3000-x) = 9250
1.5x + 12000 – 4x = 9250
1.5x - 4x = 9250 - 12000
-2.5x = -2750
2.5x = 2750
X =2750/2.5
X = 1100
Number of children enter the zoo = x = 1100
Number of adults enter the zoo = 3000 - x = 3000 - 1100 = 1900
Therefore 1100 children and 1900 adults attended the local zoo on that day.
