Drag each tile to the correct location on the algebraic problem. Not all tiles will be used,
Tema [17]

Answer/Step-by-step explanation:

4x - 7 = -2x + 12 (Given)

Add 2x to both sides

4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)

6x - 7 = 12 (Simplication)

Add 7 to both sides

6x - 7 + 7 = 12 + 7 (Addition property of equality)

6x = 19 (Simplification)

Divide both sides by 6

\frac{6x}{6} = \frac{19}{6} (Division property of equality)

x = \frac{19}{6}

Complete the square to rewrite y = x^2 – 6x + 5 in vertex form. Then state whether the vertex is a maximum or a minimum and give
VMariaS [17]
The first thing to do is to set this equal to zero, then move the constant over to the other side of the equals sign so we only have the x terms to worry about.  x^{2} -6x=-5.  Now we're ready to complete the square.  We take half the linear term, square it, and add it in to both sides.  Our linear term is -6x.  Half of 6 is 3, and 3 squared is 9, so we add 9 to both sides: x^{2} -6x+9=-5+9.  Now we will do the math on the right to get 4, and on the left we will express the perfect square binomial we created while completing this process.  (x-3)^2=4. Now we can move the constant back over by subtraction to get (x-3)^2-4=y.  Now we can see that the vertex is (3, -4).  Since this is a positive parabola, it opens upwards, like a cup, which means that the lowest part of the parabola, the vertex, is sitting at the bottom, or at a minimum value.  So our answer is C

The perimeter of the rectangle is 2,500 cm. Find the unknown side length. the other side is 750
sineoko [7]

Answer:

<h2>500 cm</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question we have

2500 = 2l + 2(750) \\ 2500 = 2l + 1500 \\ 2l = 2500 - 1500 \\ 2l = 1000 \\  \frac{2l}{2}  =  \frac{1000}{2}  \\ l =  \frac{1000}{2}  \\  l = 500

We have the final answer as

<h3>500 cm</h3>

Hope this helps you
