Answer:
(A) Is right
Step-by-step explanation:

put X= -2. in y = X+3
to get y 's value
Y = -2+3
= 1
therefore, your solution is ( -2,1)
Answer:
n + 1 = 24 million x 1.15
Step-by-step explanation:
The sales is increased 15 percent, so every year 24million is multiplyed with 1.15 to get the result... so yea
Step 1. Simplify 6 - 4(-x-9)-5 to -4(-x-9) + 1
4 - 5(2x + 11) + 6x = -4(-x-9) + 1
Step 2. Expand
4 - 10x - 55 + 6x = 4x + 36 + 1
Step 3. Simplify 4 - 10x - 55 + 6x to -51 - 4x
-51 - 4x = 4x + 36 + 1
Step 4. Simplify 4x + 36 + 1 to 4x + 37
-51 - 4x = 4x + 37
Step 5. Add 51 to both sides
-4x = 4x + 37 + 51
Step 6. Simplify 4x + 37 + 51 to 4x + 88
-4x = 4x + 88
Step 7. Subtract 4x from both sides
-4x - 4x = 88
Step 8. Simplify -4x - 4x to -8x
x = -88/8
Step 10. Simplify 88/8 to 11
x = -11
7. To find the area of a triangle you use base x height /2. so the base is 10 and the height is 25 so you do 10 x 25 first which is 250 then divide by 2 which gives you 125 so the area of each pennant is 125 cm^2 ( the ^2 means squared)
8. To find the area of a square you do length x Width. Since for a square all sides are the same the length AND the width are both 450cm. Now you just do 450 x 450 which gives you 202,500 cm^2. BUT it asks for an answer written in SQUARE METRES so you have to change 450cm to metres making it 4.5 metres x 4.5 metres = 20.25 SO THE REAL ANSWER IS 20.25 M^2
Hope this helps you out!
