How do I graph f(x) = -x^2 +2x -4
Answers
The graph of the function is the set of all points (x,y) in the plane that satisfies the equation y=f(x) y = f ( x ) . ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.

Answer:
The answer is h=15
Step-by-step explanation:
3.5 h+4.5)= 57
Let's solve your equation step-by-step.
3.5h+4.5=57
Step 1: Subtract 4.5 from both sides.
3.5h+4.5−4.5=57−4.5
3.5h=52.5
Step 2: Divide both sides by 3.5.
3.5h/3.5=52.5/3.5
h=15
Answer: h=15

If the ordered a pair (6,2) is the solution to the system, what does that mean?
Answers
It means that the point (6,2) is on both graphs at the same time. In short, it is the intersection point of the two graphs.
Algebraically, the ordered pair (x,y) = (6,2) makes all of the equations in the system to be true equations. A true equation is one where it simplifies to have the same number on both sides.
A system with at least one solution is considered a consistent system. If there is only one solution, then the system is also considered independent.
What is the value of the expression when b = 2 and c = –3? Enter your answer in the box.

Answer:
The answer to your question thinking that you're multiplying is -6
Step-by-step explanation:
The value of the expression b²+ c², when b = 2 and c = –3, is 13.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
We have an expression,
b²+ c².
The value of the expression when b = 2 and c = –3,
= (2)²+ (-3)²
= 4 + 9
= 13
Therefore, the value is 13.

Cheryl wants to find the number of hours seventh-graders do homework each week. There are 297 boys and girls in seventh grade. If Cheryl randomly surveyed 50 girls in the entire school to find the number of hours seventh-graders do homework each week, describe why she would get a biased sample
Please help ASAP
Answers
Note that Cheryl wants to find the number of hours seventh grade boys and girls spend on homework each week.
There are multiple causes of a biased sample. Two of the most obvious ones I find are:
1. She's surveying girls, but she is trying to get data on the number of hours all seventh graders (boys and girls) spend.
2. She's surveying 50 girls from the entire school, although she is trying to get data on seventh graders only.

Question on pictures ^^^^^^^^
Answers
Answer: x = 61 and y = 29
Step-by-step explanation: In this problem, notice that we
have a transversal that intersects two coplanar lines at different points.
Let's start by finding the value of y.
In the diagram, 2y and 58 are corresponding angles and if two
parallel lines are cut by a trans. corr. <'s must be congruent.
So we can setup the equation 2y = 58.
Solving from here, we find that y = 29.
Now, notice that 58 and 2x form a straight angle or a linear pair.
When two angles form a straight angle, they are supplementary.
So we can setup the equation 2x + 58 = 180.
Solving from here, we find that x = 61.

Step-by-step explanation:
To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2.

a.Each additional calorie is predicted to add approximately 0.83 mg of sodium.
b.There is a positive relationship between calories and sodium. The relationship is weak.
c.There is a positive relationship between calories and sodium. The relationship is strong.
d.As the number of calories increases, the amount of sodium decreases. The relationship is strong.
Answers
Answer:
answer C
There is a positive relationship between calories and sodium. The relationship is strong.
Step-by-step explanation:
The following is a correct interpretation of this value is option c. There is a positive relationship between calories and sodium. The relationship is strong.
The Correct interpretation of the value:Since
A nutritionist collects data from 25 popular breakfast cereals.
The value of r for the resulting scatterplot is 0.83.
So based on this, we can say that there should be the positive relationship between calories and sodium.
And, due to this, the relationship is considered to be strong.
Hence the option c is correct.
