Answer:
a. y = 2+4.3x when x = -6
substituting value of x, we get
<u>y=2+4.3*-6=2-25.8=23.8</u>
b. y = (x-3)² when x = 9
substituting value of x, we get
<u>y</u><u>=</u><u>(</u><u>9</u><u>-</u><u>3</u><u>)</u><u>²</u><u>=</u><u>6</u><u>²</u><u>=</u><u>3</u><u>6</u>
c. y=x-2 when x = 3.5
substituting value of x, we get
<u>y</u><u>=</u><u>3</u><u>.</u><u>5</u><u>-</u><u>2</u><u>=</u><u>1</u><u>.</u><u>2</u>
d. y=5x-4 when x = - 2
substituting value of x, we get
<u>y</u><u>=</u><u>5</u><u>*</u><u>-</u><u>2</u><u>-</u><u>4</u><u>=</u><u>-</u><u>1</u><u>0</u><u>-</u><u>4</u><u>=</u><u>-</u><u>1</u><u>4</u>
B. 18 because you divide the total number of cans by the number of sheets used to make them. 36/2 = 18, 180/10 = 18
Answer: girl
Step-by-step explanation: I think that you’re a girl because usually I would say boy, but then they say, “Nope!”, do I think this is a really trick question because this can describe either a boy or a girl.

Answer: 4/21
Step-by-step explanation:
Total number of tiles(possible outcomes) = 7
Number of green tiles(required outcomes) =2
Number of Blue tiles(required outcomes) = 4
Recall :
Probability (P) = Required outcome / total possible outcomes
First pick (without replacement) :
P(picking a green tile) = 2/7
Second pick :
Tiles left after first pick = 6
P(picking a blue tile) = 4/6 = 2/3
Compound probability :
P(picking a green tile) × p(picking a blue tile)
(2/7) × (2/3) = 4/21
Alright, let's solve this problem! :)
<u>First we need to subtract 5k from both sides.</u>
3k−5k>12
<u>Then we simplify 3k - 5k to -2k.</u>
-2k > 12
<u>Now we divide both sides by -2.</u>
k < -12/2
<u>Now we simplify 12/2 to 6. </u>
k < -6
✔️Done!
Have an amazing day!
