Answer:

A) Dilated 150% then reflected across the x-axis

Step-by-step explanation:

By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.

We can then also see shape A has been reflected across the x-axis to give shape B.

Answer:

$5

Step-by-step explanation:

if 5 leis are worth $25, each lei would be 25/5

25/5 is 5/1, when the denominator is one, that is unit price

the unit price is $5

30*2=15miles per min. x*y=d.

Answer:

The equation is

[tex]f(x) = - \frac{2}{30} x + 2[/tex]

Step-by-step explanation:

since the function is

[tex]f(x) = - \frac{2}{30} x + 2[/tex]

The y-intercept is 2 and the x-intercept is 30.

since the treadmill is counting down the slope of the function would be negative. she set the treadmill for 2 minute walk so at 0 minutes she has 2 minutes left. as the treadmill counts down at the 30-minute mark she will have zero minutes left.

Step-by-step explanation:

(5x +x^4) -((3x^4 )+4x), open the parenthesis and distribute the negative sign

5x+(x^4) -(3x^4) -4x, combine like terms

(-2x^4) +x

Answer:

[tex]y = {(x + 3)}^{2} - 14[/tex]

Step-by-step explanation:

The original equation

[tex] f(x) = {x }^{2} + 6x - 5[/tex]

vertex form

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

solve for the x coordinate of the vertex, h

[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]

substitute -3 back into the original equation to solve for y

[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]

substitute h and k values into the vertex form

a = 1 So we can omit it

[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]

Answer:

C 

Reason :

A square possesses reflection symmetry, with four reflection sections,  two on the  side midpoints and two via opposing corners. There are four points in a full 360° movement when the square appears precisely the same. As a result, a square possesses order 4 rotational symmetry about its center of rotation. As a result, the angle of rotation is 90°.

The image has rotational symmetry as well as reflection symmetry. Then the correct option is C.

If a line intersect the shape and the shape look identical on both sides of line, then the line is known as axis of symmetry.

From the graph, we can conclude that the image has rotational symmetry as well as reflection symmetry.

Then the correct option is C.

More about the axes of symmetry link is given below.

Answer:

6. [tex]\pi = \frac{C}{2r}[/tex]

7. Translation

Step-by-step explanation:

6: To solve for π means to isolate it on one side.

Step 1: Divide both sides by 2r.

Therefore, π = circumference over twice the radius, or circumference over diameter.

7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant

Therefore, this is a translation.

$513.75

Step-by-step explanation:

Let h represent the number of hours he worked in a week

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

Hence, his pay Is represented by equation:

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

Therefore, he earns $513.75

Here’s the answer:

Step-by-step explanation:

The sum of the four numbers divided by 4 is equal to the mean.

the sum/4 = mean

(12 + 50 + 48 + n)/4 = 30

(110 + n)/4 = 30

(110 + n) = 30 × 4

(110 + n) = 120

n = 120 - 110

n = 10

Answer:

13

Step-by-step explanation:

So the concept is that co-interior angles add up to 180 in parallel line. This means:

3x + 9 + 9x + 15 = 180

So we solve for x.

12x + 24 = 180 ( What I did was simplifying the equation).

12x + 24 - 24 = 180 - 24

12x / 12= 156 / 12

x = 13

Step-by-step explanation:

35 out of 52 people voted. You’d have to divide the total votes, 525 by the people that voted, so 35 which would equal 15.

Then, multiply 15 by the total of people that didn’t vote, 52, which would equal 780.

Answer:

Pythagorean Theorem: c2 = a2 + b2

Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh

Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.

The total area of the trapezoid is : A1 + A2 = ab + ½c2

You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2

You subtract out the 2ab: a2 + b2 = c2.

Then what is left is the proof: a2 + b2 = c2
