Answer:
B(6
Step-by-step explanation:
The number of omelets made by 18 eggs will be 6. The correct option is B.
What is the ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number. The fraction is defined as the division of the whole part into an equal number of parts.
The number of eggs required to make the number of omelets is given in the tables as:-
omelets eggs
? 18
3 9
2 6
1 3
The ratio of omelets and egg is calculated as:-
omelets: egg = 3 : 9
omelets: egg = 1:3
The number of the omelets made by 18 eggs will be calculated as below:-
omelets: egg = 1:3
omelets: 18 = 1:3
omelets = 18 x ( 1 / 3 )
omelets = 6
Therefore, the number of omelets made by 18 eggs will be 6.

Use the distributive Property to simplify: (x-7)(x-8)
Answer:
[tex]x^2-15x+56[/tex]
Step-by-step explanation:
Use the FOIL distributive method: [tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]
---------------------------------------------------------------------------------------------
Thus, [tex]\left(x-7\right)\left(x-8\right)=x\times x +x\left(-8\right)+\left(-7\right)x+\left(-7\right)\left(-8\right)[/tex]
Multiply them to get:

Apply the dilation (x, y) = (3x, 3y). What will be the coordinates of T'?
Answer:
6,0
Step-by-step explanation:
the dilation moves points from A to B
in this case we're moving point T
point T has coordinates 2,0 to start with (A)
Now let's move it to B
To do so, we need to apply the calculation
(x,y) => (3x,3y)
Substitute in point T:
(2,0) => (3x,3y)
(2,0) => (3(2),3(0))
(2,0) => (6,0)
Graph the system below and write its solution. Y=1/2x-1
-2x+y=4
You can answer no solution or infinitely many
Answer:
x = -3.3333333
y = -2.666666
Step-by-step explanation:
y = 1/2 x - 1
y = 2x + 4 The second equation has the 2x moved to the right side. The y's must be equal so equation the two equations.
1/2x -1 = 2x + 4 Subtract 1/2x from both sides.
-1 = 2x - 1/2 x + 4 Combine
-1 = 1.5x + 4 Subtract 4 from both sides
-1 - 4 = 1.5x
- 5 = 1.5x Divide both sides by 1.5
-5/1.5 = x
x = - 3.333333
Now put x = - 3.333333 into either one of the two given equations. The first one will require one less step, but it does not matter.
y = 1/2 (- 3.3333333) - 1
y = - 1.6666666 - 1
y = -2.6666666

Solve by factoring x^4+6x^2-27=0
Answer:
Step-by-step explanation:
x^4+6x^2-27=0
The two factors you need to use for 27 is 9 and 3.
Since the middle term must be plus then the 9 is also plus.
(x^2 + 9)(x^2 - 3)
x^2 + 9 can't be factored in the real number system.
x^2 - 3 = 0
(x + sqrt(3))(x^2 - sqrt(3))
The full factoring answer would be
(x^2+9)(x + sqrt(3))(x^2 - sqrt(3))

HELP NEEDED: Will mark Brainliest to best answer!! The center of a dilation is (0,0) and the scale factor is 7. If A(3,4), then which is the distance between A and A prime? A. 5 B. 7 C. 30 D. 35
Answer:
C. 30
Step-by-step explanation:
Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.
3•7 = 21=x --> A prime = (21,28)
4•7 = 28=y
[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]
