Answer:
<em>y = 4(0.75) or y = 3</em>
Step-by-step explanation:
The question is incomplete. Here is the complete question:
<em>The cost saver grocery club sells sheet cakes. Each 1/4 sheet of cake requires 0.75 teaspoon of baking soda. Which expression can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that apply.</em>
<em />
<em>Let the amount baking soda required for a whole cake be y.</em>
<em />
<em>If each 1/4 sheet of cake requires 0.75 teaspoon of baking soda, the expression that can be used to find the amount of baking soda needed for a whole is as shown below;</em>
<em />
<em>1/4 sheet of cake = 0.75 teaspoon of soda</em>
<em>1 sheet of cake = y teaspoon of soda</em>
<em />
<em>cross multiply</em>
<em>1/4 * y = 1 * 0.75</em>
<em />
<em>y/4 = 0.75</em>
<em>multiply both sides by 4</em>
<em />
<em>y/4 * 4 = 0.75 * 4</em>
<em />
<em>y = 4(0.75)</em>
<em />
<em>y = 3 teaspoon of baking soda</em>
50/36 just keep dividing the numbers by two
Answer: 
Step-by-step explanation:
Remember the point-slope equation which is 
where
is your <u>point</u> and 
is your <u>slope.</u>
<u />
Given that we substitute what you have:
Minus and minus give us positive:
Multiply slope into the parenthesis:
Calculate it:
Isolate the 
by subtracting 10 from both sides:
Your final equation is:
Hope this makes sense!
And here's the graph to prove that the line actually goes through the point
