I think when you subtract 4 from x, you are shifting the graph right horizontally 4 units. When you add 84 at the end of the function, you are shifting it up vertically 84 units. When you times it by -5, you are stretching it by a factor of 5 and flipping it upside down.

just think of how each term effects the y value.

Answer:

m∠PQR = 133

Step-by-step explanation:

∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.

3x - 5 + x + 1 = 180

4x - 4 = 180

4x = 184

x = 46

Now we simply substitute 46 in for x:

3(46) - 5 = 133

6. Suppose you bought supplies for a party. Three rolls of streamers and 15 balloons

stiks02 [169]

Answer:

Streamers are $2.50 each

Balloons are $1.50 each

Step-by-step explanation:

Make a system of equations

3s + 15b = 30

2s + 4b = 11

Solve by elimination: multiply the top equation by 2 and the bottom equation by -3.

6s + 30b = 60

-6s -12b = -33

18b = 27

b = 1.5

Plug in 1.5 as b to find s

3s + 15(1.5) = 30

3s +22.5 = 30

3s = 7.5

s = 2.5

The streamers are $2.50 and the balloons are $1.50
