Given the equations, identify which way the parabola opens by matching an equation on the left with a term on the
right.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
When the parabola has a y^2 term it opens horizontally. (Positive and negative values of y give the same value of x.)
When the parabola has an x^2 term it opens vertically. (Positive and negative values of x give the same value of y.)
The sign is negative when the opening is down or to the left.

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A(−9, −1), B(11, 9); 3 to 2
Answer:
(-2.5, 7.5)
Step-by-step explanation:
Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A(−9, −1), B(11, 9); 3 to 2
Using the formula for calculating the mid point segment expressed as;
X = ax1+bx2/a+b
Y = ay1+by2/a+b
Given
x1 = -9, y1 = -1, x2 = 11, y2 = 9, a = 3 and b = 2
Substitute
X = 3(-9)+2(11)/2
X = -27+22/2
X = -5/2
X = -2.5
Similarly
Y = 3(-1)+2(9)/2
Y = -3+18/2
Y = 15/2
Y = 7.5
Hence the required coordinate point is (-2.5, 7.5)
12. What type of triangle is shown?
Answer:
Scalene triangle, right triangle.
Step-by-step explanation:
To find out what type of triangle this is, we have to find x, so we set up an equation:
The sum of interior angles in a triangle add up to 180°
(2x + 15°) + (4x - 10°) + (x) = 180°
Open paranthesis:
2x + 15° + 4x - 10° + x = 180°
Combine like terms:
7x + 5° = 180°
Same to both sides
7x = 175°
x = 25°
We plug in x for each of the values:
2(25°) + 15° = 65°
4(25°) - 10° = 90°
25° = 25°
Because none of the angles are equal, that makes this triangle a scalene triangle, and since one of the angles is a 90° angle, that makes this triangle a right triangle

Step-by-step explanation:
The cost of tickets to a school play are $10 for adults and $6 for children under 12. If there were a total of 100 tickets sold to the play on a certain night, what equation would you use to represent the total ticket sales, T, if the number of adult tickets can be represented by a. Show and explain each step to create the equation.
Answer:
10a+6b=T------------2
Step-by-step explanation:
Given data
Let the number of adults be a
and the number of children be b
we are told that the total tickets is 100
hence
x+y=100-------------1
The cost of adult ticket = $10
The cost of children ticket = $6
since the total cost is T
Hence
10a+6b=T------------2

We use synthetic division as a tool for factoring the given expression. The coefficients of the terms given are {2, -3, -3, 2}. If x - 2 is a factor of this expression, then 2 is a root. We perform synthetic division as follows:
2 / 2 -3 -3 2
4 2 -2
-------------------------------
2 1 -1 0
Next, we determine whether or not (2x - 1)(x + 1) represents the remaining factor(s). Using -1 as divisor, we get:
-1 / 2 1 -1
-2 1
---------------------
2 -1 0
Since the remainder is zero, x + 1 must be a factor and (2x - 1) the third factor. Answer D is correct.
The solution is, (x - 2)(x + 1)(2x -1), is the expression represents the other factor, or factors, of the polynomial.

Answer:
y = 1/6x
Step-by-step explanation:
The constant of proportionality is the ratio of y to x:
k = y/x
Using the point you have circled, it is ...
k = 2/12 = 1/6
Then the equation y = kx can be written:
y = 1/6x

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles
A = 59°, a = 13, b = 14
Answer:
67.4°, C = 53.6°, c = 12.2; B = 112.6°, C = 8.4°, c = 2.2
a/sinA=b/sinB=c/sinC
a/sinA=13/0.8572=15.1662
sinB=b/a *sinA
sinB=14/13 *sin59=0.9231
B=67.4
B1=90+22.6=112.6
because sin67.4=sin112.6=0.9231
C=180-59-67.4=53.6
C1=180-59-112.6=8.4
c=a* sinC/sinA=13* sin53.6/sin59=12.2
c1=a* sinC1/sin59=13*sin8.4/sin59=2.2

If the area of the rectangle to be drawn is 20 square units, where should points B and D be located if they lie to the right of points A and C?
The question is incomplete. Here is the complete question.
If the area of the rectangle to be drawn is 20 square units, where should points B and D be located if they lie to the right of points A and C?
B(1, 3) and D(1, −2)
B(3, 3) and D(3, −2)
B(2, 3) and D(2, −2)
B(1, 2) and D(1, −3)
Answer: B(1, 3) and D(1, -2)
Step-by-step explanation: Area of a rectangle is the multiplication of its width and its length.
The rectangle to be has length, or distance from point A to point C, of 5 units.
For the area to be 20, width has to be 4.
Point B will be 4 units to the right of point A, which means:
[tex]x_{B}=x_{A}+4[/tex]
Point A has coordinates ( -3, 3), then:
[tex]x_{B}=-3+4[/tex]
[tex]x_{B}=1[/tex]
Because the points is "moved" to the right, instead of up or down, y-coordinate stays the same:
[tex]y_{B}=y_{A}[/tex]
[tex]y_{B}=3[/tex]
Point D will be 4 units to the right of point C:
[tex]x_{D}=x_{C}+4[/tex]
Coordinates of point C are ( -3, -2):
[tex]x_{D}=-3+4[/tex]
[tex]x_{D}=1[/tex]
Because a rectangle has a pair of sides parallel to each other, D's y-coordinate will also be the same:
[tex]y_{D}=y_{C}[/tex]
[tex]y_{D}=-2[/tex]
Coordinates of points B and D that makes rectangle ABCD have area of 20 square units are (1, 3) and (1, -2), respectively.

Find two points and slope !
Answer:
slope = 1
two points: (0,-6) and (6,0)
Step-by-step explanation:
Figuring out the slope:
Since we have the two points, we would need to use the slope formula of:
(y2-y1)/(x2-x1)
So it would be (-6 - 0) divided by (0 - 6) = -6/-6 = 1
slope is 1
Jennifer is four less than three times Toby's age. If Jennifer is 23, then how old is Toby? equation: solution:
Answer:
T = Toby
T=(23+4)/3
Step-by-step explanation:
If Jennifer’s age is 4 less than 3 times Toby’s age then Jennifer’s age by three,
T=(23+4)/3
and 3 times that, so we divide
T=(23+4)/3
Then Toby is 9 years of age, and shouldn’t be driving.
