Answer:

7y = x + 28

Step-by-step explanation:

Given x = 7t and y = t + 4

Here t is the parameter Now to remove it express one of it in terms of the variables (like x or y)

Given x = 7t

from this we can write t=\frac{x}{7}

Now substitute this value in the second equation

y = t + 4

y=\frac{x}{7}+4

Therefore the parameter is eliminated.

Answer:

y = x/7 + 4

Step-by-step explanation:

7y = x + 28

7y<em>(/7)</em> = x<em>(/7) </em>= 28<em>(/7)</em>

y = x/7 + 4

Hope this helps!

Looking at the picture attached, you will notice that on one side, we have a side of length 7+5=12. Next, we have a side length of 4+5+2=11. Hence, as length*width=area for a rectangle, this is the overall area of the rectangle. Next, in the picture, there are clearly two sides taken out - a 2x5 as well as a 4x5 rectangle, which are subtracted from the total area, resulting in 11*12-2*5-4*5

Solve the proportion 2x+1/6 = 7/9
Paul [167]

Answer: x=11/36

Step-by-step explanation:

Step One-Subtract 1/6 from both sides.

2x+1/6-1/6=7/9-1/6

2x=11/18

Step Two-Divide both sides by 2.

2x/2=11/18/2

x=11/36.

My math might not be correct, sorry if it is. In addition, my explanation is a bit confusing, so sorry about that too.

Determine if the pair of ratios or rates are equivalent.
Norma-Jean [14]
Yes because $18 divided by 3 bracelets makes the price per bracelet $6. $30 divided by 5 bracelets makes the price per bracelet $6. The cost per bracelet is the same so the cost to bracelet ratio is the same and both are a $6 to 1 bracelet ratio

Which equation is y = 9x2 + 9x – 1 rewritten in vertex form?
Llana [10]

Answer:

1. y = 9(x+1/2)^2 -13/4

Step-by-step explanation:

y = 9x^2 + 9x – 1

first isolate the x terms

y = 9(x^2 +x) -1

then add 1/4 inside the brackets to make it a perfect square trinomial (half of the coefficient of the x term squared is how we get 1/4)

since we just added 1/4 we need to subtract what we just added to balance the equation. so 1/4 times 9 is 9/4 ( the number we just added to the equation). then you subtract 9/4 outside of the brackets.

y = 9(x^2 +x +1/4) -1 -9/4

then simplify

y = 9(x+1/2)^2 -13/4
