The algebraic expression of the sum of y and 4 will be: [tex]y+4[/tex]

Step-by-step explanation:

As we know that An algebraic expression in mathematics is an expression which consists of:

As we have to determine the expression of the sum of y and 4.

Hence, the algebraic expression of the sum of y and 4 will be: [tex]y+4[/tex]

Answer:

y + 4

Step-by-step explanation:

Sum means it's an addition problem, so y + 4 is the answer.

Answer:

1/2 rational exponent represents a square root.

Therefore, option A is correct.

Step-by-step explanation:

As we know that raising to the one-half power i.e. [tex]\frac{1}{2}[/tex] is the same

as taking the square root.

For example, taking the square root of 4 will determine:

[tex]4^{\frac{1}{2}}[/tex]

[tex]\mathrm{Factor\:the\:number:\:}\:4=2^2[/tex]

[tex]4^{\frac{1}{2}}=\left(2^2\right)^{\frac{1}{2}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]

[tex]\left(2^2\right)^{\frac{1}{2}}=2^{2\cdot \frac{1}{2}}[/tex]

so the expression becomes

[tex]4^{\frac{1}{2}}=2^{2\cdot \:\frac{1}{2}}[/tex]

    [tex]=2^1[/tex]

    [tex]=2[/tex]         ∵ [tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a[/tex]

so, 1/2 rational exponent represents a square root.

Therefore, option A is correct.

D.) -14 + 2i and 10√2

Step-by-step explanation:

Got it right on Edge

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit. The correct option is D.

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.

To find the conjugate of a complex number, we change the sign of the complex part of the number. Therefore, the conjugate of -14-2i is -14+2i.

The modulus of the given complex number -14-2i is,

|z| = √[(-14)²+(-2)²]

    = √(196 + 4)

    = √200

    = 10√2

Hence, the conjugate and modulus of –14 – 2i are -14+2i and 10√2, respectively.

Answer:

31 Supreme tires were sold.

Step-by-step explanation:

Cost of one Supreme tire = $45

Cost of one Prestige tire = $56

Total sales = $2008

Let x represent quantity of supreme tyre

Let y represent quantity of Prestige tyre

So, the equation will be:

[tex]45x+56y=2008[/tex]

11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.

So, we are given y= 11 and we need to find value of x using above equation

[tex]45x+56y=2008\\45x+56(11)=2008\\45x+616=2008\\45x=2008-616\\45x=1392\\x=\frac{1392}{45}\\x=30.933\\ x\approx31[/tex]

So, 31 Supreme tires were sold.

Answer:

A. x²/y³

Step-by-step explanation:

Given the following data;

Length = x³y⁴

Width = [tex] xy^{7}[/tex]

Ratio = length/width

[tex] Ratio = \frac{x^{3}y^{4}}{xy{^7}}[/tex]

Simplifying the equation by applying the law of indices (division), we have;

[tex]\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2} [/tex]

[tex]\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3} [/tex]

Hence, rearranging the above values;

[tex] Ratio = \frac{x^{2}}{y^{3}}[/tex]

Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³.
