Answer:
x = -8
Step-by-step explanation:
5x - 4 + 7x = 5(2x - 4)
12x - 4 = 10x - 20
+20 +20
12x + 16 = 10x
-12x -12x
16 = -2x
divide by -2
x = -8
Answer:
x = -8
Step-by-step explanation:
5x - 4 + 7x = 5(2x - 4)
12x - 4 = 10x - 20
+20 +20

How can an area model help you set
up an equation for a problem situation?
Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.
We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.
Step-by-step explanation:
For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

Answer:
See screenshot below
Step-by-step explanation:
All you have to do it substitute the x in the rule with the x in the table. Let's do the first one in the steps below.Write the equation with the x value: y = -10(-1) + 1-10 × -1 = 10Plug 10 in: y = 10 + 110 + 1 = 11So, y = 11Now that you know how to find the rest, go ahead and do it (my answer doesn't show the work, but the answers are in the screenshot below)I hope this helps!

which of the trigonometric ratios has a value that is undefined?
Answer:
[tex]\tan \left(\frac{\pi }{2}\right)[/tex]
Step-by-step explanation:
We know that tan(x) is defined as sin(x)/cos(x):
[tex]\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\[/tex]
[tex]\tan \left(\frac{\pi }{2}\right) = 1/0 \\[/tex]
1/0 is undefined as 0 is in the denominator
