Answer:

  13 units

Step-by-step explanation:

The distance is found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((14 -2)² +(6 -1)²) = √(144 +25) = 13

The distance between the two points is 13 units.

Answer:

Step-by-step explanation:

First, we isolate the variable on the second equation so that we can have an x solution to plug in:

Now, we plug this in to the first equation:

[tex]7(-y+4)^{2} +(-y+4)^{2} =64[/tex]

We can now put the 7 into the parentheses and then square root the equation:

[tex]\sqrt{(-7y+28)^{2}} +\sqrt{(-y+4)^{2}} =\sqrt{64}\\-7y+28-y+4=8\\-8y=40\\y=-40[/tex]

We then plug this in to the original equation to find x

[tex]x+-40=4\\x=-36[/tex]

This means y=-40 and x=-36. I believe that's what you were asking. Let me know if it is something else

Answer:

A hypothesis is "is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome.". And an experiment is "is defined as to try out something new or to test a theory. An example of experiment is when you try out a new hair style. An example of experiment is when you use test tubes and chemicals in a lab to complete a project and to try to better understand chemical reactions.".

By substitution, we will see that the solution of the system is:

x = 13, y = 11, z = -1

The correct option is D.

Here we have a system of 3 equations:

x + y + 8z = 16

2x + 7z = 19

4x - 4y + 4z = 4

I will solve it by substitution, first, let's simplify the equations. Here we can divide the third equation by 4 so we remove all the common factors, then the system becomes:

x + y + 8z = 16

2x + 7z = 19

x - y + z = 1

Now, I will isolate x on the second equation:

x = (19 - 7z)/2 = (19/2) - (7/2)*z = 9.5 - 3.5*z

Now we can replace that on the other two equations:

(9.5 - 3.5*z) + y + 8z = 16

(9.5 - 3.5*z) - y + z = 1

Rewriting the system we get:

y + 4.5z = 6.5

-y - 2.5z = -8.5

Now we can isolate y on the first equation:

y = 6.5 - 4.5z

Replacing that on the other equation we get:

-(  6.5 - 4.5z) - 2.5z = -8.5

-6.5 + 4.5z - 2.5z = -8.5

2z = -8.5 + 6.5 = -2

z = -2/2 = -1

Then the value of y is:

y = 6.5 - 4.5z = 6.5 - 4.5*(-1) = 11

And the value of x is:

x = 9.5 - 3.5*z = 9.5 - 3.5*(-1) = 13

So the solution of the system is:

x = 13, y = 11, z = -1

The correct option is D.

Answer:

(9, 18) (3, 6) Plz correct me if wrong

Step-by-step explanation:

Jace bought 4 cookies and 2 brownies from the bakery.

Let x represent the number of cookies and y represent the number of brownies.

Since he bought $9 worth of cookies and brownies. Each cookie costs $0.75 and each brownie costs $3. hence:

0.75x + 3y = 9      (1)

Also, he bought twice as many cookies as brownies, hence:

x = 2y

x - 2y = 0     (2)

Solving equation 1 and 2 simultaneously gives x = 4, y = 2

Hence Jace bought 4 cookies and 2 brownies from the bakery.

Given:

Two small pizzas, a liter of soda, and a salad costs $14.

One small pizza, a liter of soda, and three salads costs $15.

Three small pizzas, a liter of soda, and two salads costs $22.

To find:

The cost of each item.

Solution:

Let x be the cost of a small pizza.

y be the cost of a liter of soda

z be the cost of a salad.

According to the question, two small pizzas, a liter of soda, and a salad costs $14.

[tex]2x+y+z=14[/tex]           ...(i)

One small pizza, a liter of soda, and three salads costs $15.

[tex]x+y+3z=15[/tex]         ...(ii)

Three small pizzas, a liter of soda, and two salads costs $22.

[tex]3x+y+2z=22[/tex]      ...(iii)

From (i), we get

[tex]z=14-2x-y[/tex]        ...(iv)

Putting [tex]z=14-2x-y[/tex] in (ii), we get

[tex]x+y+3(14-2x-y)=15[/tex]

[tex]x+y+42-6x-3y=15[/tex]

[tex]-5x-2y=15-42[/tex]

[tex]-(5x+2y)=-27[/tex]

[tex]5x+2y=27[/tex]            ...(v)

Putting [tex]z=14-2x-y[/tex] in (iii), we get

[tex]3x+y+2(14-2x-y)=22[/tex]

[tex]3x+y+28-4x-2y=22[/tex]

[tex]-x-y=22-28[/tex]

[tex]-(x+y)=-6[/tex]

[tex]x+y=6[/tex]

Multiply both sides by 2.

[tex]2x+2y=12[/tex]    ..(vi)

Subtracting (vi) from (v), we get

[tex]5x+2y-2x-2y=27-12[/tex]

[tex]3x=15[/tex]

[tex]x=5[/tex]

Putting x=5 in (vi), we get

[tex]2(5)+2y=12[/tex]

[tex]10+2y=12[/tex]

[tex]2y=12-10[/tex]

[tex]2y=2[/tex]

[tex]y=1[/tex]

Putting x=5 and y=1 in (iv), we get

[tex]z=14-2(5)-(1)[/tex]

[tex]z=14-10-1[/tex]

[tex]z=3[/tex]

So, [tex]x=5,y=1,z=3[/tex].

Therefore, the cost of a pizza is $5, cost of a liter of soda is $1 and cost of salad is $3.
