Answer:

7(50 + 3)

7(50) + 7(3)

371

Step-by-step explanation:

7(53)

50 can be written as (50 + 3)

∴7(53) = 7(50 + 3)

Proceeding with the above expression we get;

7(53) = 7(50 + 3)

= 7(50) + 7(3)

Completing the above expression we get;

7(53) = 7(50) + 7(3)

= 350 + 21

= 371

Describe the symmetry of these functions

Oduvanchick [21]

If it was line symmetry it would need to repeat the same shape twice, which the first follows but the second doesn’t.
if it was rotational, you would need to be able to take the shape in the top right and rotate it counterclockwise or clockwise to get the shape that locks in place. that doesn’t follow that.
both line and rotational symmetry is incorrect because the first example would need to lock up inside the right side of that example.

the answer is C

Answer:

90 m²

Step-by-step explanation:

The given linear dimensions have the ratio ...

red/blue = (6 m)/(4 m) = 3/2

The ratio of areas is the square of the ratio of the linear dimensions:

(red area)/(blue area) = (3/2)²

S = (blue area)(9/4) = (40 m²)(9/4)

S = 90 m²

What is the domain of the function y = square root x+6 -7?

salantis [7]

Answer:

-6 ≤ x < ∞

Step-by-step explanation:

You want the domain of the function y = √(x+6) -7.

<h3>Domain</h3>

The domain of a function is the set of x-values for which the function is defined. On a graph, it is the horizontal extent of the graph.

The square root function is undefined for negative arguments, so that limits the domain of the given function:

x+6 ≥ 0

x ≥ -6 . . . . . domain of the given function

<em>Additional comment</em>

When the domain is written in interval notation, both the left and right ends of the interval must be specified.

[-6, ∞)

The square bracket identifies -6 as being part of the domain. The parenthesis is used with ∞, because that number has no specific value.
