Answer: You'll have 10 nickels and 18 dimes.


Step-by-step explanation:

Its a guessing question.

10 nickles = .50

18 dimes = $1.80

$1.80 + .50= 2.30

daser333 [38]
Should be 7 feet. 6+6=12 then 26-12=14, divide that by 2 (for the other two sides of the rectangle), you'll get 7 ft.

This is algebra 1 id appreciate it if you could help me thx!
Orlov [11]

Answer:

Option 4: 0

Step-by-step explanation:

Given the function, f(x) = 3x, and the domain. {-3, 1, 4}:

Substitute the values of each domain as inputs into the function:

<h3>x = -3</h3>

f(-3) = 3(-3)

f(-3) = -9

<h3>x = 1</h3>

f( 1 ) = 3( 1 )

f( 1 ) = 3

<h3>x = 4</h3>

f(4) = 3(4)

f(4) = 12

Therefore, the correct answer is option 4) 0, because there is no input value that provides an output of 0. You were only given three domain values that provided its corresponding outputs.

Reflect A(29,-32) across the x-axis. *
Phantasy [73]

The coordinate (20, -32), the reflection of the coordinate over the x-axis is (20, 32)

<h3>Reflection of coordinates</h3>

If a coordinate (x, y) is reflected across the x-axis, the resulting coordinate after reflection is (x,-y)

Note that the y-ccordinate is negated after the reflection.

Given the coordinate (20, -32), the reflection of the coordinate over the x-axis is (20, 32)

Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the
bagirrra123 [75]

Answer:

c = -6

d = -1

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

a = (3,5) --- Point on A

a' = (-3,-6) --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

(x,y) \to (x,-y)

So, we have:

(3,5) \to (3,-5)

Next, is to calculate the translation from (3,-5) to (-3,-6)

This is calculated using:

3 + c = -3

and

-5 + d = -6

So, we have:

3 + c = -3

c = -3-3

---- i.e. Shift by 6 units to the left

-5 + d = -6

d = 5 - 6

d = -1  --- i.e. Shift by 1 unit down
