Complete the table below for the equation y = x^2 + 2x - 1. Then, graph the equation on the provided graph grid.
Answers
Answer:
y = x^2 + 2x - 1
x = -4
y = -4^2 + 2(-4) - 1
y = 16 + (-8) - 1
y = 7
x = -3
y = -3^2 + 2(-3) - 1
y= 9 + (-6) - 1
y = 2
x = -2
y = -2^2 + 2(-2) - 1
y = 4 + (-4) - 1
y = -1
x = -1
y = -1^2 + 2(-1) - 1
y = 1 + (-2) - 1
y = -2
x = 0
y = 0^2 + 2(0) - 1
y = 0 + 0 - 1
y = -1
x = 1
y = 1^2 + 2(1) -1
y = 1 + 2 -1
y = 2
x = 2
y = 2^2 + 2(2) - 1
y = 4 + 4 - 1
y = 7

Write a linear equation for the graph
Answers
Answer:
y=-1/2x+0
Step-by-step explanation:
First, find the slope by choosing two points and counting up and over (rise over run). Then, find where the line crosses the y-axis to get the y-intercept.
For the two points, let's choose (0,0) and (-2,1). You can either count up and over to get slope, or you can use the slope formula which is y2-y1/x2-1x.
1-0/-2-0 = -1/2.
Since this line represents a negative slope, your slope is -1/2.
Now, looking at the graph, you can see that the line crosses the y-axis at 0. This is your y-intercept.
What is the relationship between a scalene triangle and the location of its orthocenter? Explain.
A. The orthocenter will always be inside the scalene triangle, since the orthocenter is always inside any type of triangle.
B. The orthocenter will always be outside the scalene triangle, since the orthocenter is always outside any type of triangle.
C. The orthocenter will always be on the scalene triangle, since the orthocenter is always on a triangle with no congruent side lengths.
D. The orthocenter will be inside, on, or outside the scalene triangle, depending on whether it is acute, right, or obtuse, respectively. The number of congruent sides does not affect the location of the orthocenter.
Answers
Answer:
Actually the correct answer is D
Step-by-step explanation:
This question is based on the scalene triangle and orthocenter. Therefore, the correct option is D i.e. The orthocenter will be inside, on, or outside the scalene triangle, depending on whether it is acute, right, or obtuse, respectively. The number of congruent sides does not affect the location of the orthocenter.
In this question we have to choose correct appropriate option related to relationship between a scalene triangle and the location of its orthocenter.
By the definition of scalene triangle:
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.
Orthocenter:
The orthocenter of a triangle is the intersection of the triangle's three altitudes.
Therefore, the correct option is D i.e. The orthocenter will be inside, on, or outside the scalene triangle, depending on whether it is acute, right, or obtuse, respectively. The number of congruent sides does not affect the location of the orthocenter.

Noah and his friends are going to an amusement park. The total cost of admission for 8 students is $100, and all students share the cost equally. Noah brought $13 for his ticket. Did he bring enough money to get into the park? Explain your reasoning.
Answers
Answer:
yes
Step-by-step explanation:
100 / 8 = 12.5
Answer:
yes; he brought $13, and the ticket is $12.50
Step-by-step explanation:
Since there are 8 people, and all tickets cost the same, and the total is $100, then each ticket is $100/8.
$100/8 = $12.50
Since $13 is greater than $12.50, then Noah has enough money for his ticket.

Are the ratios 11:20 and 1:2 equivalent? yes or no
Answers
Answer:
no
Step-by-step explanation:
11/20 is equal to 0,55
Answer:
No
Step-by-step explanation:
In order to know whether ratios are equivalent, you have to convert them intro fractions first, then cross multiply.
The fraction form of 11:20 is [tex]\frac{11}{20}[/tex]
The fraction form of 1:2 is [tex]\frac{1}{2}[/tex]
Next is to cross multiply both to see if they have equivalent (the same) values.
[tex]\frac{11}{20}[/tex] = [tex]\frac{1}{2}[/tex]
11 x 2 = 20 x 1
22 ≠ 20
Therefore, 11:20 and 1:2 are not equivalent.

Step-by-step explanation:
Given
[tex]\sqrt{x + 2}= {-x}[/tex]
Required
Find the possible values fo x
[tex]\sqrt{x + 2}= {-x}[/tex]
Square both sides
[tex]( \sqrt{x + 2})^2= ({-x})^2[/tex]
[tex]x + 2 = x^2[/tex]
Equate to 0
[tex]x^2 - x - 2 = 0[/tex]

Factorize:
[tex]x(x + 1) - 2(x + 1) = 0[/tex]
[tex](x -2)(x +1) = 0[/tex]

Answer:
x = 2, y = 23
x = 3, y = 39
x = 4, y = 56
x = 5, y = 67
Step-by-step explanation:
Given:
14x - 3 where $14 is per hours on part-time work and $3 is cost to and from work.
y = 14(2) - 3
y = 28 - 3
y = 23
y = 14(3) - 3
y = 42 - 3
y = 39
y = 14(4) - 3
y = 56 - 3
y = 53
y = 14(5) - 3
y = 70 - 3
y = 67
x = 2, y = 23
x = 3, y = 39
x = 4, y = 56
x = 5, y = 67

Jesse practices the trumpet for a total of 165 minutes during the first week of school. He practices for 245 minutes during the second week. A. Estimate the total amount of time Jesse practices by rounding to the nearest 10 minutes.
Answers
Answer:
410 minutes
Step-by-step explanation:
Given that:
Time for which Jesse practices trumpet in the first week = 165 minutes
Time for which Jesse practices trumpet in the second week = 245 minutes
To find:
The total amount of time rounded to the nearest 10 minutes.
Solution:
To find the total amount of time for which Jesse practices, we need to add the time taken for practice in the first week and the time taken for practice in the second week.
Therefore, total time taken = 165 + 245 = 410 minutes
It is already rounded off to the nearest 10 minutes.
Therefore, the answer is:
Total amount of time for which Jesse practices = 410 minutes
