General Formulas and Concepts:

Algebra I

Step-by-step explanation:

The solution to the systems will be where the 2 lines intersect. According to the graph, the 2 lines intersect at (1, -2). Therefore, our answer is D. x = 1, y = -2.

Answer:

=324

Step-by-step explanation:

6(3)6(3)

=324

Answer:

The answer is A.(-4,3)

Step-by-step explanation:

Multiply the first equation by -3,and multiply the second equation by 1.

−3(x+y=−1)

1(3x−4y=−24)

Becomes:

−3x−3y=3

3x−4y=−24

Add these equations to eliminate x:

−7y=−21

Then solve−7y=−21for y:

−7y=−21

[tex]\frac{-7y}{-7} =\frac{-21}{-7}[/tex]

y=3

Now that we've found y let's plug it back in to solve for x.

Heres our original equation

x+y=−1

Substitute 3 for y in x+y=−1:

x+3=−1

x+3+−3=−1+−3(Add -3 to both sides)

x=-4

Answer:

14447 cm³

Step-by-step explanation:

Given that:

Diameter = 11.4cm

Height = 3.7cm

boxes has 4 layers ; 5 rows by 7

Hence, dimension of shipping boxes :

Height = height of can * layer = 3.7 * 4 = 14.8 cm

Length = 5 * diameter of can = 5 * 11.4 = 57cm

Width = 7 * diameter of can = 7 * 11.4 = 79.8 cm

Volume of shipping boxes :

Height * Length * Width

14.8 * 57 * 79.8 = 67319.28 cm³

For fish can:

Radius = diameter / 2 = 11. 4 / 2 = 5.7cm

Volume (V) of can = pi*radius^2*height

V = π * 5.7^2 * 3.7 = 377.66027 cm³

Total volume of cans = number of cans * V

Total volume of cans = (4 * 5 * 7 * 377.66027)

Total volume of cans = 52872.4378 cm³

Empty space = difference in volume

= 67319.28 - 52872.4378

= 14446.8422

= 14447 cm³ (approx)

Step-by-step explanation:

I hope this helps

Answer: both c

Step-by-step explanation:

           9 is u can multiply 6x 8 when u cut one of the rectangles into 4s, u can see that each of the piece is worth 12, so 48+36+36=120

           11 Is u can see 1 square unit is each of the boxes. U can infer that 4 of the square units will be able to fit in that shape.

Answer:

Vertex: (-2, 2)

Step-by-step explanation:

The x-coordinate of the vertex would be as follows;

x = -b/2a = 8/2(-2) = -8/4 = -2

respectively the y-coordinate of the vertex would be y(-2) = -2(-2)^2 - 8(-2) - 6 = -2(4) + 16 - 6 = - 8 + 10 = 2

Your vertex would be a maximum of (-2, 2)

* I say maximum as the coefficient of x^2 is -2, and it is less than zero so the parabola opens downward

Answer: i think its 4 if my calculations are right

Step-by-step explanation:

Answer:

Sentence Fram: I found x-intercept by substitute y by 0 and I found y-intercept by substitute x by 0

x-intercept = (6, 0), y-intercept = (0, -3) ⇒ C

Step-by-step explanation:

∵ The equation of the graph is 6x - 12y = 36

→ Equate y by 0 to find x

∵ y = 0

∴ 6x - 12(0) = 36

∴ 6x - 0 = 36

∴ 6x = 36

→ Divide both sides by 6 to find x

∴ x = 6

∴ The x-intercept = (6, 0)

→ Equate x by 0 to find y

∵ x = 0

∴ 6(0) - 12y = 36

∴ 0 - 12y = 36

∴ -12y = 36

→ Divide both sides by -12 to find y

∴ y = -3

∴ The y-intercept = (0, -3)

∴ Sentence Fram: I found x-intercept by substitute y by 0 and I found

   y-intercept by substitute x by 0

∴ x-intercept = (6, 0), y-intercept = (0, -3)

Answer:

[tex]3x^3y^2\:+1\div 9y=3x^3y^2+\frac{1}{9}y[/tex]

Step-by-step explanation:

Given the expression

[tex]3x^3y^2\:+1\div9y[/tex]

According to the order of operation with respect to PEMDAS

so

Thus, the expression becomes

[tex]3x^3y^2+\frac{1}{9}y[/tex]

There are no like terms involved in the expression.

The expression is very much simplified.

Thus:

[tex]3x^3y^2\:+1\div 9y=3x^3y^2+\frac{1}{9}y[/tex]

EDGE 2021

Answer:

b

Step-by-step explanation:

Answer:

Option (c) is correct.

Step-by-step explanation:

The edge length of a cube is 5 cm.

We need to find the volume of the cube.

The formula for the volume of a cube is given by :

[tex]V=a^3[/tex]

Put a = 5 cm in above formula

[tex]V=(5)^3\\\\=125\ cm^3[/tex]

Hence, cubic centimeters is the appropriate unit for measuring the volume of a cube.

Answer:

12 quarts of 60% pineapple juice concentrate should be used

Step-by-step explanation:

Let the amount for the 60% be x

20% of 4 + 60% of x = 50% of (x + 4)

So we have;

0.2(4) + 0.6(x) = 0.5(x + 4)

0.8 + 0.6x = 0.5x + 2

0.6x-0.5x = 2-0.8

0.1x = 1.2

x = 1.2/0.1

x = 12

Answer:

67?

Step-by-step explanation:

Answer and Step-by-step explanation:

The cost of all the 6 magazines are: 6x

The cost of all the 9 newspapers are 9(x-3)

So, the total cost is the sum of all the items:

6x + 9(x-3) = 51

6x + 9x - 27 = 51

15x = 78

x = 5.2

Since the cost of one magazine is $x, the cost will be $5.20.
