Step-by-step explanation:

4(6x) + 4(12) Used distributive property

Answer:

Step-by-step explanation:

1.

-3 + 8x ≥ 21

+3            +3

8x ≥ 24

divide both sides by 8

x ≥ 3

2.

d is false, because when you plug 5 in for x the solution would come out to be 19 < 17

Answer:

x = 1[tex]\frac{1}{6}[/tex], y = 3[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

y = -2x + 6 --- Equation 1

y = 4x - 1 --- Equation 2

Since both (-2x + 6) and (4x - 1) have the same total, y, they are equal.

-2x + 6 = 4x - 1

Isolate the like terms.

6 + 1 = 4x + 2x

Evaluate like terms.

6x = 7

Find x.

x = [tex]\frac{7}{6}[/tex]

x = 1[tex]\frac{1}{6}[/tex]

Substitute x = [tex]\frac{7}{6}[/tex] into Equation 2:

y = 4x - 1

y = 4([tex]\frac{7}{6}[/tex]) - 1

  = 4[tex]\frac{2}{3}[/tex] - 1

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

Answer:

  no

Step-by-step explanation:

When the second equation is put in standard form like the first equation is, then you can see they are different. They do not define the same line.

  3x +2y = 7

Answer:

[tex]\theta=24^\circ[/tex]

Step-by-step explanation:

Trigonometry and Right Triangles:

The ratios of the sides of a right triangle are called trigonometric ratios. Any angle or side length can be calculated using the appropriate trigonometric ratio.

Please refer to the image below. The balloon is 100 feet high and the rope has a length of 250 feet. The right triangle formed allows us to apply a trigonometric ratio that relates the two given side lengths: the hypotenuse and the opposite leg to angle θ.

The sine ratio is defined as:

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle \sin\theta=\frac{100}{250}=0.4[/tex]

[tex]\displaystyle \sin\theta=0.4[/tex]

Calculating θ:

[tex]\theta=\arcsin 0.4[/tex]

[tex]\theta=23.6^\circ[/tex]

To the nearest degree:

[tex]\mathbf{\theta=24^\circ}[/tex]

Answer:

( i ) [tex]\boxed{1}[/tex]

( ii ) [tex]\boxed{2^{6n - 3m - 2}\times 3^{3 - m}}[/tex]

.

Step-by-step explanation:

( Part i )

[tex]\left(\frac{1}{x^{a - b}} \right)^{a + b}\left(\frac{1}{x^{b + a}} \right)^{b - a}[/tex]

[tex]= \left(\frac{1}{x^{(a - b)(a + b)}} \right)\left(\frac{1}{x^{(b + a)(b - a)}} \right)[/tex]

[tex]= \left(\frac{1}{x^{a^2 - b^2}} \right)\left(\frac{1}{x^{b^2-a^2}} \right)[/tex]

[tex]= \frac{1}{x^{a^2 - b^2 + (b^2 - a^2)}}[/tex]

[tex]= \frac{1}{x^0}[/tex]

[tex]= \frac{1}{1}[/tex]

[tex]= \boxed{1}[/tex]

.

( Part ii )

[tex]\frac{2^{m + n}\times 3^{2m + 3} \times 4^{2n -1}}{6^{2m + n}\times 12^{m - n}}[/tex]

[tex]=\frac{2^{m + n}\times 3^{2m + 3} \times 2^{2(2n -1)}}{(2\times3)^{2m + n}\times (3\times 2^2)^{m - n}}[/tex]

[tex]=\frac{2^{m + n}\times 3^{2m + 3} \times 2^{4n -2}}{2^{2m + n}\times3^{2m + n}\times 3^{m - n}\times 2^{2(m - n)}}[/tex]

[tex]=\frac{2^{m + n + 4n - 2}\times 3^{2m + 3}}{2^{2m + n + 2m - 2n}\times3^{2m + n + m - n}}[/tex]

[tex]=\frac{2^{m + 5n - 2}\times 3^{2m + 3}}{2^{4m - n}\times3^{3m}}[/tex]

[tex]= 2^{m + 5n - 2 - (4m - n)}\times3^{2m + 3 - 3m}[/tex]

[tex]= \boxed{2^{6n - 3m - 2}\times 3^{3 - m}}[/tex]

Answer:

x= -5

Step-by-step explanation:

First get X alone by dividing both sides by -4.2

-4.2x=21

-4.2. -4.2

then you're left with X = -5

To verify your answers, multiply -5 by -4.2

Answer:

(a/b)^k=a^k/b^k

Step-by-step explanation:

Using the laws of exponents, we know that (a/b)^k=a^k/b^k.

I couldn't get it to format correctly so just know that the "/" are for the fraction signs and the "^" is for the exponent marking.

Answer:

a^k / b^k

The equation of the line will be written as y=2x+4 because $2 per hour and then adding your $4 deposit.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the line models the cost of renting a bike. It costs​ $2 per hour plus a​ $4 deposit.

The equation of the line is,

y = 2x + 4

Here,  $2 per hour and then add your $4 deposit.

Answer: Let's solve for x.

−x−y=6

Step 1: Add y to both sides.

−x−y+y=6+y

−x=y+6

Step 2: Divide both sides by -1.

x=−y−6

Answer:

x=−y−6

Let's solve for x.

5x−7y=66

Step 1: Add 7y to both sides.

5x−7y+7y=66+7y

5x=7y+66
