Answer:

None of the above.

Step-by-step explanation:

The system of equations which should have the same solution as the system below;

x + 4y = 11

4x + 2y = 16

x + 4y = 11

-8x - 4y = - 32

This system of equations is missing from your choices.

The trick is that -2 is multiplied to the second equation of the first system.

i.e -2 (4x + 2y = 16) gives; -8x - 4y = -32

This is a cross-sectional view of candy bar ABC. A candy company wants to create a cylindrical container for candy bar ABC so th

Rzqust [24]

TheThe smallest diameter of wrapper that will fit the candy bar is 5cm.

<h3>Smallest diameter</h3>

Given:

AD = DC

AC = AD + DC

Segment AD = 2.5cm

Hence:

AC = AD + AD (AD = DC)

AC = 2AD

Where:

AD=2.5

So,

AC = 2(2.5cm)

AC = 5cm

Therefore the smallest diameter of wrapper that will fit the candy bar is 5cm.

"which of the numbers below can be classified as an integer" and the options are . 10÷2 , -0.3 ,√20 ,. 0.4

Ivahew [28]

Answer:

The number 10/2 = 5 is an integer.

Step-by-step explanation:

An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...

Integer can be positive, negative of zero.

$\frac{10}{2}=5$

It is a whole number so it is an integer.

- 0.3

It is not an integer as it has a fractional part.

$\sqrt20$

It also has a fractional part, so it is not an integer.

0.4

It also has a fractional part, so it is not an integer.

Which of the following equations is in equation formed when completing the square on y^2 - 12 y= -27

bogdanovich [222]

Answer:

$(y-6)^2=9$

Step-by-step explanation:

Given

$y^2 - 12y = -27$

Required

Get equivalent expression using completing the square

<em>Follow these steps:</em>

<em>Take the coefficient of y; That is -12</em>

<em>Divide it by 2; That is (-12/2)</em>

<em>Square it: (-12/2)^2</em>

<em />

Add to both sides of the equation

$y^2 - 12y + (\frac{-12}{2})^2= -27 + (\frac{-12}{2})^2$

$y^2 - 12y + (-6)^2= -27 + (-6)^2$

$y^2 - 12y + 36= -27 + 36$

$y^2 - 12y + 36= 9$

Expand the right-hand side

$y^2 - 6y - 6y + 36= 9$

Factorize:

$y(y-6)-6(y-6) =9$

$(y-6)(y-6)=9$

$(y-6)^2=9$
