Given the vertex and another point, write the equation in vertex form: vertex (2, -5) point (3, -2)
Answer:
y = 3(x - 2)² - 5
Step-by-step explanation:
Let the equation of the parabola is,
y = a(x - h)² + k
Here, (h, k) is the vertex of the given parabola.
Since, vertex of the parabola is (2, -5)
Equation of the parabola will be,
y = a(x - 2)²- 5
Since, parabola passes through a point (3, -2),
-2 = a(3 - 2)²- 5
-2 + 5 = a(1)
a = 3
Therefore, equation of the parabola will be,
y = 3(x - 2)²- 5
solve the simultaneous equation plz x
Answer:
x=4,y=3
Step-by-step explanation:
x=19-5y if we transpose equation 2 for x.
Plug that into equation 1
4(19-5y)+3y=25
76-20y+3y=25
76-25=17y
51=17y
y=3
Plug y=3 into equation 2
x+5(3)=19
x=19-15=4
We are having two equations,
4x + 3y = 25 (Equation No 1)x + 5y = 19 (Equation No 2)★ From Equation No 2 :-
>> x + 5y = 19
>> x = 19 - 5y
★ From Equation No 1 :-
Substitute here the value of x which we got above as (19 - 5y).
>> 4x + 3y = 25
>> 4 (19 - 5y) + 3y = 25
>> 4 × (19 - 5y) + 3y = 25
>> 76 - 20y + 3y = 25
>> 76 - 17y = 25
>> -17y = 25 - 76
>> -17y = -51
>> 17y = 51
>> y = 51 / 17
>> y = 3
★ Finding out value of x :-
>> x = 19 - 5y
>> x = 19 - 5(3)
>> x = 19 - 5 × (3)
>> x = 19 - 15
>> x = 4

Use substitution to solve the following system of equations.
x + 2y = 13
3x - 5y = 6
Answer:
{1} x + 2y = 13
{2} 3x - 5y = 6
x = 13 - 2y
substituting into {2}
3x -5y = 6
3( 13 - 2y) - 5y = 6
39 - 6y -5y = 6
-11y = 6 -39
y = -33 /-11
( minus and minus cuts in fraction, so the answer will come in positive)
y = 3
now , substituting into {1}
x + 2(3) = 13
x = 13 -6
x = 7
so,
the solution are:-
x = 7
y = 3
I hope this helps a little bit.
1. Are two congruent figures similar? Explain.
Answer:
Yes
Step-by-step explanation:
Congruence means two objects (whether two dimensional or three dimensional) are identical in size and shape. Everything about them -- their angles, lengths of sides, overall dimensions -- are identical. Similar means being the same shape. Two congruent figures must be the same shape, so they are similar.
Hope that helps!

Amy owns 3 1/3 acres of farmland. She grows beets on 1/6 of the land. On how many acres
of land does Amy grow beets?
Plz
Answer:
5/9 acres
Step-by-step explanation:
3 1/3 areas is 10/3
1/6 of the land is covered with beets
[tex]\frac{10}{3} * \frac{1}{6} =\frac{10}{18}[/tex]
[tex]\frac{10}{18}[/tex] will simplify to [tex]\frac{5}{9}[/tex]
Hence the answer is 5/9 acres
4)What kind of shape do the parametric equations make?X= 7sin(theta), y= 2cos(theta)
A) Circle
B) Ellipse
C) Square
D) Parabola
Answer:
Ellipse
Step-by-step explanation:
Given
[tex]x = 7sin\theta[/tex]
[tex]y= 2cos\theta[/tex]
Required
The kind of shapes with such equations
This answer to this question is(B) Ellipse
The parametric equation of an ellipse is represented as:
[tex]x = asin(\theta)[/tex] and [tex]y = bcos(\theta)[/tex]
In this case:
[tex]a=7\ b = 2[/tex]
So:
[tex]x = 7sin\theta[/tex] and [tex]y= 2cos\theta[/tex]

In January the students in a class red 72 books in February they read 56 books what is the approximate percentage decrease in the number of books read from January to February
Answer: -12.5%
72 + 56 = 128
72 x / 128 x 100 = 56.25
56 / 128 x 100 = 43.75
43.75 - 56.25 = - 12.5
The cone and cylinder above have the same radius and height. The volume of the cylinder is 48 cm3. What is the volume of the cone?
A.
24 cm3
B.
16 cm3
C.
96 cm3
D.
144 cm3
Answer:
Option B (16 cm³)
Step-by-step explanation:
GIVEN :-
Both cone and cylinder have same radius and height.Volume of cylinder = 48 cm³TO FIND :-
Volume of coneFACTS TO KNOW BEFORE SOLVING :-
Volume of a cylinder having radius 'r' and height 'h' is [tex]\pi r^2h[/tex]Volume of a cone having radius 'r' and height 'h' is [tex]\frac{1}{3} \pi r^2 h[/tex]Hence ,
Volume of cylinder = Thrice the volume of cone
[OR]
Volume of cone = One third of volume of cylinder
PROCEDURE :-
Volume of cone = [tex]\frac{1}{3} (Volume \: of \: cylinder) = \frac{48}{3} = 16 cm^3[/tex]

Equation:3x+95x+21
Which equation represents a circle that contains the point (-5, 3) and has a center at (-2, 1)? Distance formula: vaa -02 (x - 1)2 + ( + 2)2 = 25 (x + 2)2 + (-1)=5 O (* + 2) + (-1) - 25 (x-1) + ( + 2) = 5
Given:
The center of the circle = (-2,1).
Circle passes through the point (-5,3).
To find:
The equation of the circle.
Solution:
Radius is the distance between the center of the circle and any point on the circle. So, radius of the circle is the distance between the points (-2,1) and (-5,3).
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(-5-(-2))^2+(3-1)^2}[/tex]
[tex]r=\sqrt{(-5+2)^2+(2)^2}[/tex]
[tex]r=\sqrt{(-3)^2+(2)^2}[/tex]
On further simplification, we get
[tex]r=\sqrt{9+4}[/tex]
[tex]r=\sqrt{13}[/tex]
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius of the circle.
Substitute h=-2, k=1 and [tex]r=\sqrt{13}[/tex].
[tex](x-(-2))^2+(y-1)^2=(\sqrt{13})^2[/tex]
[tex](x+2)^2+(y-1)^2=13[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-1)^2=13[/tex].

A mix of factoring by grouping. Factor the exressions. 17ax+17a-x-1 Please explain/show steps on how to do this!
Answer:
[tex](17a-1)(x+1)[/tex]
Step-by-step explanation:
Given: Expression is [tex]17ax+17a-x-1[/tex]
To factor: the given expression
Solution:
Take [tex]17a[/tex] common from the first two terms and [tex]-1[/tex] from the last two terms.
[tex]17ax+17a=17a(x+1)[/tex]
and
[tex]-x-1=-(x+1)[/tex]
So,
[tex]17ax+17a-x-1=17a(x+1)-1(x+1)\\=(17a-1)(x+1)[/tex]
Therefore,
[tex]17ax+17a-x-1=(17a-1)(x+1)[/tex]

Mr. Gibbs bought number of shirts for the new members of his band. The cost for number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts did Mr. Gibbs buy?
Answer:
Number of shirts= 6
Step-by-step explanation:
Giving the following information:
The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.
First, we need to calculate the net total price paid for the shirts:
Net total cost= 77.49 - 3.99= $73.5
Now, the number of shirts bought:
Number of shirts= 73.5 / 12.25
Number of shirts= 6
