2. The football team is selling clothes to raise money. The team need \( \$ 800 \). Tee-shirts cost \( \$ 10 \) per shirt, and sweatshirts cost \( \$ 30 \) each at least one shirt and one sweatshirt, and would like to sell over Select all the equations or inequalities that could describe this si represent the number of tee-shirts and \( s \) represent the number a. \( s>0 \) b. \( t<0 \) c. \( t+s<800 \) d. \( t+s>70 \) e. \( 10 t+30 s \leq 800 \) f. \( 10 t+30 s>800 \)

Multiply: \( 9 \times 800= \) Submit

B. \( 3 x-4>x \)

6 8

Plot \( A, B \) and \( C \) and join them up. \( \triangle A^{\prime} B^{\prime} C^{\prime} \) is the image of \( \triangle A B C \) after an enlargement by a factor of 3 . i) Sketch \( \triangle A^{\prime} B^{\prime} C^{\prime} \) and show the coondinates on the sketch. ii) Draw a rectangle around \( \triangle A^{\prime} B^{\prime} C^{\prime} \) and determine the area of \( \triangle A^{\prime} B^{\prime} C \). iii) Draw a rectangle around \( \triangle A B C \) and determine the area of \( \triangle A B C \). ivi) Show, by calculation, that the ratio of the areas is \( 1: 9 \).

Simplify. \[ \frac{35 x y}{49 x y} \]
