Determine if the table shows a proportional relationship.


x 18.6 54.3 58.8
y 6.2 18.1 19.6

Yes, it is proportional because all y over x ratios are equivalent to one third.
Yes, it is proportional because all y over x ratios are equivalent to one fourth.
No, it is not proportional because 18.6 over 6.2 does not equal 18.1 over 54.3.
No, it is not proportional because 18.1 over 54.3 does not equal 58.8 over 19.6.

(3r²•2r³)³


Simplify the exponents. Please show me how to do the step by step?? I'm not sure how to solve these when they have parentheses

Answers

(2n²•n³•3n¹)²

First, simplify inside the parentheses. We multiply the coefficients and exponents. The coefficients: 2×3=6. and the exponents: 2×3×1=6. All together that gives: [tex](6n^6)^2[/tex]Then multiply the inside of the parentheses by itself since it's the exponent is 2. Therefore we end with [tex]36n^12[/tex]

(y•4y²)³

Same approach. Multiply the inside which gives [tex]4y^3[/tex] Then calculate that to the power of 3.

[tex]4y^3[/tex]×[tex]4y^3[/tex]×[tex]4y^3[/tex]=[tex]64y^9\\[/tex]

(4b³•b)²

[tex]=(4b^4)^2\\=4b^4\cdot4b^4\\=16b^8[/tex]

(3s²•s³)²

[tex]=(3s^5)^2\\=3s^5\cdot3s^5\\=9s^{10}[/tex]

(3r²•2r³)³

[tex]=(6r^5)^3\\=6r^5\cdot6r^5\cdot6r^5\\=216r^{15}[/tex]

The perimeter of the rectangle is __ feet.

Answer:

15.5y+9ft if im not wrong

Step-by-step explanation:

solve the equation for y: y + 7 = 5/4 (x + 16)

Answers

To solve the equation for y, we need to get y by itself on one side of the equation.

The first step is to get rid of the fraction on the right side of the equation by multiplying both sides by 4:

4y + 28 = x + 16

Then, we need to move the x term to the left side of the equation by subtracting x from both sides:

4y + 28 - x = 16

Then, we need to move the constant term 28 to the left side of the equation by subtracting 28 from both sides:

4y - x = -12

Finally, we have the equation in the form y = (1/4)x - 3, so the solution for y is y = (1/4)x - 3

It is important to note that in this solution we have used the distributive property and followed the order of operations to get to the final result, if you don't follow this steps you might get a different result.

STEPS FOR SOLVING LINEAR EQUATIONy+7=45​(x+16)Use the distributive property to multiply 45​ by x+16.y+7=45​x+20Swap sides so that all variable terms are on the left hand side.45​x+20=y+7Subtract 20 from both sides.45​x=y+7−20Subtract 20 from 7 to get −13.45​x=y−13Divide both sides of the equation by 45​, which is the same as multiplying both sides by the reciprocal of the fraction.45​45​x​=45​y−13​Dividing by 45​ undoes the multiplication by 45​.x=45​y−13​Divide y−13 by 45​ by multiplying y−13 by the reciprocal of 45​.x=54y−52​SOLVE FOR Yy=45x​+13
