Answer:
C
Step-by-step explanation:
We are trying to find the profit for every pizza sold. Since looking at the x axis, the point in which its x coordinate is 1 cannot be easily identified. Thus, we shall derive the answer using a point that can be easily identified.
We observe that the two points, (10,12) and (20,24) sits nicely on the graph. I will be using the first coordinate above to derive the answer.
For every 10 pizzas sold, $12 of profit is made.
10 pizzas ----- $12 profit
1 pizza ----- $12 ÷10= $1.20
Hence, the unit rate of profit for the pizzas is $1.20 per pizza.
Answer:
-35/6
Step-by-step explanation:
We need to find the value of x , And the given pair of Rational numbers are equal.
<u>Question</u><u> </u><u>(</u><u>I)</u><u> </u><u>:</u><u>-</u><u> </u>
→ 3/4 = 7/x
→ 7/x = 3/4
→ 1/x = 3/4 × 1/7
→ 1/x = 3/28
→ x = 28/3
<u>Question</u><u> (</u><u>ii)</u><u> </u><u>:</u><u>-</u><u> </u>
→ x/7 = -5/6
→ x = -5/6 × 7
→ x = -35/6
<h3>
• Hence the value of x is -35/6 .</h3>

A true or false question is a question that gives you a statement, and asks whether it's true (correct) or false (wrong).
