210 cm^2

3x-1 + 4x+1 + 3x = 70

Simplify  

10x = 70

divide by 10

x = 7

So,

1/2 * 3x * 3x-1

1/2 * (3*7) * (3*7 -1)

1/2 * 21 * 20

21 * 10

210 would be your final answer

Answer:

210 cm^2

Step-by-step explanation:

3x-1 + 4x+1 + 3x = 70

10x = 70

x = 7

Now, Area of the triangle is 1/2 * b * h

therefore,

1/2 * 3x * 3x-1

1/2 * (3*7) * (3*7 -1)

1/2 * 21 * 20

21 * 10

210

210 is the area!

Hope this helps! mark as brainliest if helped! thanks!

Answer:

10.4%

Step-by-step explanation:

The original price = $2.40

Price after drop = $2.15

The drop = $2.40 - $2.15 = $0.25

Percentage decrease = \frac{decrease}{original-price} × 100

i.e Percentage decrease = \frac{0.25}{2.40} × 100 = 10.41666667%

Or 10.4% (Rounded up to nearest tenth of a percent).

XY is a translation of XY.
seropon [69]

Given:

The graph of a translation. X'Y' is a translation of XY.

To find:

The rule of the translation.

Solution:

Let the rule of the translation be

(x,y)\to (x+a,y+b)            ...(i)

So, we need to find the value of a and b.

From the given graph, it is clear that X(-4,-9) and X'(-1,0).

Using (i), the image of X(-4,-9) is

X(-4,-9)\to X'(-4+a,-9+b)

We have, X'(-1,0). So,

X'(-4+a,-9+b)=X'(-1,0)

On comparing both sides, we get

-4+a=-1

a=-1+4

a=3

And,

-9+b=0

b=9

So, the missing values in the rule of the translation are 3 and 9 respectively.

Therefore, the rule of translation is (x,y)\to (x+3,y+9).
