y = 2
A horizontal line, parallel to the x-axis has equation y = c
where c is the value of the y-coordinate the line passes through.
( - 2, 2) has y- coordinate of 2
equation of horizontal line is therefore y = 2

Baking a tray of corn muffins takes 4 cups of milk and 3 cups of wheat flour. Baking a tray of bran muffins takes 2 cups of milk and 3 cups of wheat flour. A baker has 20 cups of milk and 18 cups of wheat flour. He makes $3 profit per tray of corn muffins and $2 profit per tray of bran muffins. How many trays of each type of muffin should the baker make to maximize his profit?
Answer:
2 barn and 4 corn
Step-by-step explanation:
Here we have to pay attention to milk, because both recipes require the same amount of flour, 3 cups, so the flour will be used in equal amounts whatever the recipe we use. Given this, we can only bake 6 trays at most.
Can we bake 6 of barn? YES! Using all our flour and 6*2=12 cups of milk and getting 6 trays of barn muffins. This will give us $2 * 6 = $12. However we keep 8 cups of milk with not use, that could have been used to bake one of corn that are twice as profits as barn. What happens if we replace one of the 6 barn trays by one of corn?
This way we will have 5 of barn and 1 of corn and we will be using 10 + 4 = 14 cups of milk. Our profits will be: $2*5 + $3*1 =$13. This will improve our income!
Lets replace another barn by one of corn. This way we have 4 of barn and 2 of corn: $2*4 + $3*2 = $14. Again, more income!!
Lets replace another and have 3 barn and 3 corn: $2*3 + $3*3 = $15. And we can bake them, as they need 2*3 = 6 cups for barn and 4*3=12 cups of milk for corn.
If we replace another we will have 2 of barn and 4 of corn. Our income will be: $2*2 + $3*4 = $16. This implies using 4 cups of mil for barn and 16 cups of mil for corn. So, we use all of our milk.
Any change in the distribution of barn and corn will, even impossible to bake as there will not be more ingredients or less profit

The points are (c), (b), (c), (c), (c) respectively. The estimates are made by finding the closest square roots, and by rounding to the nearest tenth if necessary.
Explanation:1. The two square roots used to estimate √5 are √4 and √9 (option c); because 5 is in between 4 and 9.
2. The two square roots used to estimate √43 are √36 and √49 (option b); because 43 is in between these two perfect squares.
3. An estimate for -√66 is -8 (option c); since 66 is closer to 64 which is a perfect square of 8.
4. An estimate for √3 is 1.7 (option c); since the actual value of √3 is approximately 1.732, rounding to the nearest tenth gives 1.7.

A leaf hangs from a branch 12 feet in the air. It falls to the ground at a rate of 0.25 feet per second. Which graph could represent the leaf’s height in feet as a function of time, in seconds, after leaving the branch?
The fourth graph is showing the correct relation between the leaf’s height in feet as a function of time, in seconds.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The height is 12 feet and the rate of falling of leaf is 0.25 feet per second.
Check for the 20th-second leaf's position.
Position = 0.25 x 20 = 5 feet
So in 20 seconds leaf will travel 5 feet so the height of the leaf from the ground is,
H = 12-5 = 7 feet
The fourth graph is showing the position at 7 feet in 20 seconds.
Therefore, the fourth graph is showing the correct relation between the leaf’s height in feet as a function of time, in seconds.

Which zero pair could be added to the function f(x)=x2 +12x+6 so that the function can be written in vertex form
The most general proccedure for this type of problems is the following:
For a quadratic function of the following form [tex]f(x)=x^2+bx+c[/tex]; where b and c are real numbers.
1) Identify the value that accompanies the x, that is, the value "b"
2) Divide the value of b by 2 and then square it: [tex](\frac{b}{2})^2[/tex]
3) Add and subtract in the function the value of [tex](\frac{b}{2})^2[/tex]

Which answer is a reasonable estimate to the following problem? 194 x 476
To estimate the product of 194 x 476, we round each number to the nearest hundred and multiply. After rounding, the multiplication is 200 x 500, which equals 100,000. This is a reasonable estimate for the multiplication problem.
Explanation:The subject of this question is Mathematics, and the grade level appears to be Middle School. The student is asking for a reasonable estimate of the product of 194 and 476.
To estimate the product of 194 x 476, we should round each number to a convenient figure before multiplying. Both numbers round to the nearest hundred, with 194 rounding down to 200 and 476 rounding up to 500.
The estimate calculation would therefore be:
Round 194 down to 200 (because it is closer to 200 than to 300).Round 476 up to 500 (because it is closer to 500 than to 400).Multiply the rounded numbers: 200 x 500.When we multiply these rounded figures, we get:
200 x 500 = 100,000
This is a reasonable estimate for the product of 194 x 476.

Match the conditional statement p→q, the converse q→p, the inverse ~p→~q, and the contrapositive ~q→~p in words.
Let p be “two angles are supplementary” and let q be “the measures of the angles sum to 180°.”
For the text answers:
conditional - If 2 lines are supplementary then the measure of the angles sum is 180
converse - If the measure if the angle sum is 180 then the 2 lines are supplementary
inverse - If 2 lines are not supplementary then the measure if the angle sum is not 180
contrapositive - If the measure if the angle sum is not 180 then 2 lines are not supplementary.
answer to the picture one:
conditional - If you do all your math homework then you will do well on the test.
converse - If you do well on the test then you do all your math homework
inverse - If you do not do all your math homework then you will not do well on the test.
contrapositive - If you do not well on the test then you did not do all your math homework
The conditional statement reads as if two angles are supplementary, then their measures sum to 180 degrees. Its converse flips this relationship around. The inverse and contrapositive negate the original and converse statements, respectively.
Explanation:In this context, the conditional statement p→q would read: if two angles are supplementary, then the measures of the angles sum to 180°. The converse, q→p, would be: if the measures of the angles sum to 180°, then the angles are supplementary.
The inverse, ~p→~q, changes the original statement to: if two angles are not supplementary, then the measures of the angles do not sum to 180°. Finally, the contrapositive, ~q→~p, would be: if the measures of the angles do not sum to 180°, then the angles are not supplementary. These variations of the original conditional statement allow us to analyze the relationship between the angles and their measures in different ways.
