Solve the proportion.<br> 4<br> y<br> =<br> 7<br> ?<br> y =
Leni [432]

Answer:

y=28/5

Step-by-step explanation:

Okay so for this we can use cross- multiplication. Basically, the product of the numerator of the first number and the denominator of the second is equal to the product of the denominator of the first and the numerator of the second.

What I mean is: 4*7=5*y

so,

28=5y

y=28/5

Prove that the diagonals of a rectangle bisect each other. the midpoint of is _____
Deffense [45]
In this attached picture, we can prove that triangles AOB and COD are congruent. ∠CDO and ∠ABO are equal because they are alternate angles. Similarly, ∠OAB and ∠OCD are equal because they are alternate angles, as well. We have a rectangle and in the rectangle, opposite sides are equal; AB = CD. Then, because of Angle-SIde-Angle principle, we can say that triangles AOB and COD are equal. If triangles are congruent, then OD = OB and OC = AO. Applying congruency to the triangles ACD and BCD, we can see that these triangles are also congruent. It means that the diagonals are equal. Since, OD = OB and OC = AO, it proves that the point O simultaneously is the midpoint and intersection point for the diagonals.

If k(x) = 5x-6, which expression is equivalent to (k+ k)(4)?
RSB [31]
<h2>Adding Functions</h2>

Example:

(f+g)(x)=f(x)+g(x)

To add this, we can substitute in the functions and combine like terms.

<h2>Solving the Question</h2>

We're given:

  • k(x)=5x-6
  • (k+k)(4)=?

Add <em>k</em> to <em>k</em>:

(k+k)(x) = k(x)+k(x)\\(k+k)(x) = 5x-6+5x-6\\(k+k)(x) = 10x-12

Input <em>x</em> as 4:

(k+k)(4) = 10x-12\\(k+k)(4) = 10(4)-12\\(k+k)(4) = 40-12\\(k+k)(4) = 28

<h2>Answer</h2>

(k+k)(4)=28
