Answer:
(0, 13)
Step-by-step explanation:
The midpoint is halfway between the line segment. First find the distance from the starting point to the midpoint.
2-1 = 1. So Since the midpoint is behind the start point, we are going backwards (moving to the left on the x axis).
So 1 space left from the midpoint is 1-1=0.
For y, the distance between the start and mid is 6 - -1 = 6+1 = 7 spaces. Then add 7 spaces to the midpoint value of 6, so 7+6 = 13. We moved upwards on the y axis.

PLEASE HELP!!!!!!!What has to be true if you want to solve a quadratic?
Answer:
Here you go
Step-by-step explanation:
The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math. Then the formula will help you find the roots of a quadratic equation, i.e. the values of x where this equation is solved.
Is this a square root graph?
Is this graph a reflection of its parent graph?
this graph shifted _
The equation to this graph would transform the parent function f(x) to _
Answer:
Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
Step-by-step explanation:
Consider the function
y = f(x)
The rule of horizontal translation
y = f(x-h)
When 'h' is positive, the function is shifted to the right.
When 'h' is negative, the function is shifted to the left.
The rule of implying vertical reflection across the x-axis
y = -f(x)
Applying the rule:
We know that the square root function is
[tex]y=\sqrt{x}[/tex]
We know that if the graph would be reflected across the x-axis, then
[tex]y=-\sqrt{x}[/tex]
We know that is horizontally translated or shifted 3 units to the left, it implies +
3 inside the radical implies. Then the transformed function becomes .
Please check the attached diagram. From the diagram,
The blue graph shows the parent function [tex]y=\sqrt{x}[/tex].The red graph shows the transformed function i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
ted's company has recieved an order to print 10^6 pages. ted's company has 100 machines , each of which can print 10^4 pages a day. ted's company can print the 10^6 pages in blank.
in exponent form, this number of days can be represented as blank
Answer:
1 day ; 10^0
Step-by-step explanation:
Given that:
Order received = 10^6 pages
Number of machines = 100
Daily printing capability by each machine = 10^4
Hence, total output per day = (10^4) * 100 = 10^4 * 10^2 = 10^4+2 = 10^6
Number of days required = number of order / daily output
Number of days = 10^6 / 10^6 = 1
In exponent form:
10^6 / 10^6 = 10^6-6 = 10^0
What is included between two congruent sides in an isoceles triangle
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.

Katie is purchasing plates and mugs for her house.
She would like to buy at least 8 items. Plates cost
$8 each and the mugs cost $7 each, and she plans
to spend no more than $112. Write a system to
model the situation and then solve.
Step-by-step explanation:
Plate: $8 each
Mug: $7 each
Spend Limit: $112
Items Wanted: 8
Considering she wants eight items, she can split that in half and buy four of each item, plate and mug.
8 * 4 = 32
$32 for 4 plates.
7 * 4 = 28
$28 for 4 mugs.
However, if she wanted to spend all the money, she could buy a few more of each item.

The vertex of a parabola is (3,-2) and another point on the parabola is (2,3) find the equation of the parabola in vertex form
Answer:
[tex]y = 5 ( x - 3 ) ^2 -2[/tex]
OR
[tex]y+2= 5 ( x - 3 ) ^2[/tex]
Step-by-step explanation:
Vertex form of a parabola is given as:
[tex]y = a ( x - h ) ^2 + k[/tex]
Where ([tex]h,k[/tex]) is the vertex and [tex](x,y)[/tex] are the points on the parabola.
We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).
[tex]h = 3,k = -2[/tex]
First of all, putting the vertex in the vertex equation as given above:
[tex]y = a ( x - 3 ) ^2 + (-2)[/tex]
Now, putting the values of [tex]x, y[/tex] as 2, 3 and let us find the unknown variable [tex]a[/tex]:
[tex]3 = a ( 2 - 3 ) ^2 + (-2)\\\Rightarrow 3 = a -2\\\Rightarrow a = 5[/tex]
Therefore, the equation in vertex form can be written as:
[tex]y = 5 ( x - 3 ) ^2 -2[/tex]
OR
[tex]y+2= 5 ( x - 3 ) ^2[/tex]

Sam bought a 7/8 -foot piece of wood to make some small boxes to hold his insect collection. He used 3/16 foot of wood for each box. Which equation can be used to show how many boxes Sam made?
Answer:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
Step-by-step explanation:
Total piece of wood bought = 7/8 foot
Piece of wood used for each small box = 3/16 foot
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
= 7/8 foot ÷ 3/16 foot
= 7/8 × 16/3
= 7×16 / 8×3
= 112 / 24
= 4 16/24
= 4 2/3 small boxes
The equation is:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

The residents of a city voted on wether to raise property taxes. The ratio of yes votes to no votes was 8 to 5. If there was 6856 yes votes, what was the total number of votes
Answer:
The total number of votes cast in the election was 11,141.
Step-by-step explanation:
To determine the number of negative votes in the voting, taking into account that the ratio of votes between positive and negative is 8 to 5 and that there were 6,856 positive votes, it is necessary to perform the following calculation:
6.856 / 8 x 5 = X
857 x 5 = X
4.285 = X
Therefore, there were 4,285 negative votes in the election. So, since 4,285 + 6,856 equals 11,141, the total number of votes cast in the election was 11,141.
If point P is Four-sevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?
Answer:
m into5
Step-by-step explanation:
Answer:
ANSWER 4:3
Step-by-step explanation:
Given : A point P is 4/7 of the distance from M to N.
∴ Let the distance between M to N be d.
Also, the point P partition the directed line segment from M to N .
Thus , MN = MP+PN
Now, the ration of MP to PN will be :-
∴ Point P partitioned the line segment MN into 4:3.
A train covers the distance between two cities A and B at 70km/h during certain time. If it goes 10km/h faster, it will cover the same distance in one hour less. Find the distance between the two cities and the time it takes to do the first trip

On a unit circle, the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal distance from the y-axis to the same point. What is sin of theta
Answer:
2/√5
Step-by-step explanation:
A unit circle is a circle of unit radius. This means that the radius of a unit circle is 1.
Let a represent the horizontal distance. Therefore the vertical distance = twice the horizontal distance = 2a
We can get the hypotenuse using Pythagoras theorem:
hypotenuse² = a² + (2a)²
hypotenuse² = a² + 4a²
hypotenuse² = 5a²
hypotenuse = √5a²
hypotenuse = a√5
sin(θ) = opposite / hypotenuse
sin(θ) = vertical distance / hypotenuse
sin(θ) = 2a / a√5
sin(θ) = 2/√5

80 middle-school students went on a field trip to watch a performance of Alice In Wonderland. When the teacher took a survey, 70% of the students responded that they enjoyed the play. About how many students enjoyed the play?
Answer:
56 students
Step-by-step explanation:
Because there are 80 students and only 70% enjoyed it, 70% is equal to 0.7 so you would multiply 80 by 0.7.
