C.(2,1,0)

Step-by-step explanation:

on edg

The solution to the following system is [tex](2,1,0)[/tex].

Algebra is defined as the study of mathematical symbols and in which letters and symbols are used to represent numbers.

We have,

[tex]3x+3y+6z=9[/tex]    [tex](i)[/tex]

[tex]x+3y+2z=5[/tex]    [tex](ii)[/tex]

[tex]3x+12y+12z=18[/tex]  [tex](iii)[/tex]

To find the solution to the above give algebraic equations,

We have to find values of [tex]x,y,z[/tex].

So,

We will be putting [tex]z=0[/tex] in equation [tex](i)[/tex],

[tex]3x+3y+6(0)=9[/tex]

[tex]3x+3y=9[/tex]    [tex](iv)[/tex]

Now,

We will be putting [tex]z=0[/tex] in equation [tex](ii)[/tex],

[tex]x+3y+2(0)=5[/tex]

[tex]x+3y=5[/tex]  

[tex]x=5-3y[/tex]    [tex](v)[/tex]

Using equation [tex](iv)[/tex] & [tex](v)[/tex],

We get,

[tex]3(5-3y) +3y=9[/tex]

[tex]15-9y+3y=9[/tex]

[tex]-6y=-6[/tex]

[tex]y=1[/tex],

Now we have value of  [tex]y=1[/tex], putting this value in equation  [tex](v)[/tex],

[tex]x=5-3(1)[/tex]

[tex]x=2[/tex],

Hence, we can say that option [tex](2,1,0)[/tex] is the correct answer.

Answer:

271 boxes

Step-by-step explanation:

Answer:

3 crates are required for 3258 cookies

Step-by-step explanation:

since the boxes can have 12 cookies each

number of boxes = number of cookies / number of cookies per box

number of boxes = 3,258 cookies / 12 cookies/box = 271.5 boxes = 272 boxes (271 completely filled and one halfway filled)

since each crate can hold 100 boxes

number of crates = number of boxes / number of boxes per crate

number of crates = 272 boxes/ 100 boxes/crate = 2,72 crates = 3 crates (2 completely filled and one 72% filled)

therefore the number of required crates for 3258 cookies is 3

Answer:

The posters cost $52.07.

Step-by-step explanation:

First, you have to calculate the cost of the 20 posters by multiplying the price per poster for the quantity:

$2.89*20=$57.8

Then, you have to calculate the 15% discount by multiplying the cost for 15% and subtracting that amount from the cost:

$57.8*15%=$8.67

$57.8-$8.67=$49.13

Finally, you have to calculate the 6% of $49.13 and add the result to that amount:

$49.13*6%=$2.94

$49.13+$2.94=$52.07

According to this, the answer is that the posters cost $52.07.

Answer:

[tex]y = -\frac{10}{3}x -23[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-9,7)[/tex]

[tex](x_2,y_2) = (-6,-3)[/tex]

Required

Determine the line equation

We start by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where:

[tex](x_1,y_1) = (-9,7)[/tex]

[tex](x_2,y_2) = (-6,-3)[/tex]

So, we have:

[tex]m = \frac{-3- 7}{-6 - (-9)}[/tex]

[tex]m = \frac{-3- 7}{-6 +9}[/tex]

[tex]m = \frac{-10}{3}[/tex]

[tex]m = -\frac{10}{3}[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex] ---- Point slope form of an equation

Where:

[tex]m = -\frac{10}{3}[/tex]

[tex](x_1,y_1) = (-9,7)[/tex]

[tex]y - y_1 = m(x - x_1)[/tex] becomes

[tex]y - 7 = -\frac{10}{3}(x - (-9))[/tex]

[tex]y - 7 = -\frac{10}{3}(x +9)[/tex]

Open bracket:

[tex]y - 7 = -\frac{10}{3}x -\frac{10}{3}*9[/tex]

[tex]y - 7 = -\frac{10}{3}x -10*3[/tex]

[tex]y - 7 = -\frac{10}{3}x -30[/tex]

Collect Like Terms

[tex]y = -\frac{10}{3}x -30 + 7[/tex]

[tex]y = -\frac{10}{3}x -23[/tex]

Hence:

The equation is: [tex]y = -\frac{10}{3}x -23[/tex]

5 obtuse triangle and isosceles

6 obtuse and scalene

7 equiangular triangle and equilateral

8 right triangle and isosceles

I'm not sure about the bottom part since I can't really see sorry.

Step-by-step explanation:

acute - when a angle is less than 90 degrees

Obtuse - when an angle is more than 90 degrees

Right - when angle is at 90 degrees also it will have a square in the triangle to let you know that it 90 degrees/right angle.

Scalene triangle - when side have an uneven length.

isosceles triangle - when two side are equals.

equilateral - when all sides are equal.

equiangular -  have all equal angles

Answer:

$32

Step-by-step explanation:

Since the question says that all the apples were sold for a total of $160, this means that you have to add the additional basket of the friend's to Olivia's. Since Olivia has 4 baskets of apples and her friend has 1, 4+1=5. Since you're trying to find the unit price for 1 basket, you take the total of $160 and divide it by 5 to find how much each basket of apples costed. Since 160/5 is 32, $32 is your answer.
