A cup and saucer cost $3.10 at the local store. The cup costs $2.00 more than the saucer. How much does each cost?

AlekseyPX

Answer: cup is $2.55

Saucer $0.55

Step-by-step explanation:

Cost of cup and saucer is $3.10

Let the cup be x

And saucer be y

I.e

X+y= 3.10......equation 1

Cup which is X is $2 more than the saucer

I.e x=2+y......equation 2

Substitute for X in equation 1

(2+y)+y=3.10

2+2y=3.10

2y=3.10-2

2y=1.10

Y=1.10/2

Y=$0.55

Substitute for y in equation 2

X=2+y

X=2+0.55

X=$2.55

Therefore

The cup is $2.55

The saucer is $0.55

Kim preformed a transformation on rectangle ABCD to create image A’B’C’D’, as shown in the figure below

Paul [167]

Answer:

Reflection over the x-axis

Step-by-step explanation:

Process of elimination, all of the other answers and the image is reflected over the x-axis perfect.

If rotated 270 degrees the image would be vertical

If reflected over the y-axis the image would be in Quadrant I not II

If rotated 90 degrees the image would be vertical as well.

So all othe the other answers are wrong making B) right.

Consider the following sets. U = {ordered pairs on a coordinate plane} A = {ordered pair solutions to y = x} B = {ordered pair s

4vir4ik [10]

Answer:

(0,0)

Step-by-step explanation:

We have,

U = { (x,y) : x,y belong to real numbers }

A = { (x,y) : (x,y) is a solution of y=x }

B = { (x,y) : (x,y) is a solution of y=2x }

We need to find the ordered pair (x,y) that belong to A $\bigcap$ B.

Let, (x,y) belong to A $\bigcap$ B

i.e. (x,y) belong to A and (x,y) belong to B

i.e. y = x and y = 2x

i.e. x = 2x

i.e. x = 0

Now, substitute x= 0 in any of the equation say y = x, we get y = 0.

Hence, the ordered pair satisfying A $\bigcap$ B is (0,0).

If f(x) = 3x + 3, g(x) = 3x + 3, and h(x) = x + 3, what is [g o f o h](–5)?

emmasim [6.3K]

The answer would be -6.
Start by substituting -5 into the 'h' function.
h(-5) = -5 + 3 = -2
Now substitute this answer into the 'f' function.
f(-2) = 3(-2) + 3 = -3
now substitute this answer into the 'g' function
g(-3) = 3(-3) + 3 = -6
D is your answer
