Answer:

A = increasing ( positive slope )

D = increasing ( positive slope )

C = decreasing ( negative slope )

B = constant ( zero slope )

Step-by-step explanation:

If number on y-axis increases with increase of x then it is increasing.

If number on y-axis decreases with increase of x then it is decreasing.

If number on y-axis stays the same with increase of x then it is constant.

What is the inverse of the function? f(x) = 2x - 10?

gulaghasi [49]

Answer:

Step-by-step explanation:

Let $f(x)=y$

y=2x-10

Switch x and y,

x=2y-10

x+10=2y

(x/2)+5=y

So $f^{-1}(x)=\frac{x}{2}+5$

In Jaden’s yard, there is a triangular garden patch. He wants to plant a geranium in the patch at a point equidistant from all i

Lelu [443]

Answer:

Jaden has to plant the geranium in the circumcentre of the triangular yard in order such that it is equidistant from all its vertices.

Step-by-step explanation:

In Jaden’s yard, there is a triangular garden patch. He wants to plant a geranium in the patch at a point equidistant from all its vertices.

<em>" The CIRCUMCENTER (C) of a triangle is the point in the plane equidistant from the three vertices of the triangle "</em>

Hence Jaden has to plant the geranium in the circumcentre of the triangular yard in order such that it is equidistant from all its vertices.

a. Is it possible for a shape to have both reflectional and rotational symmetry? If so, provide an example with a line of symmet

AnnZ [28]

Yes. For example, the shape I will use is the circle.

No matter how you rotate the circle, it will always look the same. If you reflect the circle over any drawen line in which it passes through the middle, the two halves created would be congruent.

Addie walked 2 1/2 miles in 45 minutes. Suzie covered 2 2/5 miles in 2/3 of an hour.

N76 [4]

Answer:

Suzie's speed was 3.6 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph (miles per hour)

x ----> the distance in miles

y ----> the time in hours

$s=\frac{x}{y}$

Find Suzie's speed

we have

$x=2\frac{2}{5}\ mi$

$y=\frac{2}{3}\ h$

substitute

$s=2\frac{2}{5}:\frac{2}{3}$

Convert mixed number to an improper fraction

$2\frac{2}{5}=2+\frac{2}{5}=\frac{2*5+2}{5}=\frac{12}{5}$

substitute

$s=\frac{12}{5}:\frac{2}{3}=\frac{36}{10}=3.6\ mph$
