The general form of an parabola is 4y2+40y+3x+103=0. What is the standard form of the parabola?
9514 1404 393
Answer:
x = -4/3y² -40/3y -103/3
x = -4/3(y +5)² -1
Step-by-step explanation:
Solve for x.
x = (4y² +40y +103)/(-3)
x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US
__
Taking our clues from the graph*, we can write the vertex form equation as ...
x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places
_____
* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...
x = a(y -(-5))² +(-1) = a(y +5)² -1
The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.

Answer:
A video of a drumming session.
Answer:
D. A video of a drumming session
Explanation:
A presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
Basically, any speaker who wishes to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation and using a multimedia resource.
In this scenario, Diego has written a feature story about a drumming circle. Thus, what he should include in his visual presentation to interest the audience in the drumming experience is a video of a drumming session.
Generally, they say action speaks louder than words, and people often believe what they can see.

The number of calories in Swiss cheese varies directly with the weight of the cheese. There are about 200 calories in 50 grams of Swiss cheese. Willie ate 70
grams of Swiss cheese. About how many calories did he eat?
Answer:
He ate about 4.6 of cheese
Step-by-step explanation:
Answer:
280 calories
Step-by-step explanation:
let's make a proportion: 50/70 = 200/x
cross multiply: 50 * x = 70 * 200
multiply: 50x = 14000
divide each side by 50: x = 280
answer is 280 calories

The ratio of the perimeter of a square to the length of a rectangle is 5:6.
The ratio of the length to the width of the rectangle is 3:2.
The perimeter of a rectangle is 60cm.
Find the area of the square.
Answer:
=225/16cm^2
Step-by-step explanation:
Given
The ratio of the length to the width of the rectangle =3:2.
The perimeter of a rectangle = 60cm.
Solution
Let length=3x
width=2x
Perimeter of rectangle=2(length + width)
2(3x+2x)=60
5x*2=60
10X=60
X=60/10
X=6
SO LENGTH =3×6=18cm
WIDTH=2×6
=12cm
Let perimeter of the square=5x
Length of rectangle=6x
6x = 18
X=18/6
X=3
SO PERIMETER OF SQUARE=5×3
4SIDE=15
Side=15/4
Area of square=15/4×15/4
=225/16cm^2
PLSS HELP with 1 3 and 4
Answer:
1.) slope is 6
2.) slope is -4
4.)slope is undefined
Step-by-step explanation:
1.) For one we can use the equation y2-y1/ x2-x1
First, pick any 2 points that you want to use to plug into the equation
(0, -3) and (1, 3)
Next, plug in and solve!
3-(-3)/ 1-0= 6
The slope is 6
2.) We can use this same equation for the problem and plug in!
(-1, 5) (2,-7)
-7- 5/ 2-(-1)= -4
The slope is -4!
4.) Use the same equation and find the slope!
(8, 1) and (8, 2)
2-1/ 8-8= undefined
Because we cannot divide by a 0 the slope is undefined!

What is the slope of the line that contains these points?
x 9 13 17 21
y -24 -21 -18 -15
Answer: m=3/4
Step-by-step explanation:
Looking at the table given, we can assume two of the points are (9,-24) and (13,-21). To find the slope with given points, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We can plug the two points in and solve.
[tex]m=\frac{-21-(-24)}{13-9} =\frac{3}{4}[/tex]
Now, we know that the slope is 3/4.
Answer:
slope = 3/4

Joshua rented a movie for $4.49 from Cinema Rentals. If the movie is not returned on the due date, Cinema Rentals charges an
additional $2.25 a day until the movie is returned. If Joshua returns the movie x days after its due date, which of the following
functions represents the total cost, R(x), he paid for the movie rental?
Answer:
R(x) = 2.25x + 4.49
Step-by-step explanation:
Equation form: R(x) = mx + b
m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.
b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.
Since we know the value of m and b, we can write the equation:
R(x) = 2.25x + 4.49

Answer:
y = -4/5x +3/5
Step-by-step explanation:
The 2-point form of the equation for a line can be useful.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (3 -(-1))/(-3 -2)(x -2) -1
y = 4/(-5)(x -2) -1
y = -4/5x +8/5 -1
y = -4/5x +3/5
Two competing sports equipment suppliers sell footballs at different prices. Supplier A charges $85 in shipping, and charges $2.59 per football. Supplier B charges $50 shipped, and charges $4.29 per football. A school wants to buy 40 balls.
What is the equation for supplier A? Answer:
What is the equation for supplier B? Answer:
Which supplier has the lowest average cost per ball? Answer:
The equation for supplier A and supplier B will be y = 2.59x + 85 and y = 4.29x + 50, respectively. Supplier A has the lowest average cost per ball.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Footballs are sold at varying prices by two rival sports equipment vendors. Supplier A costs $85 for shipping and $2.59 for each football. Supplier B costs $50 for shipping and $4.29 per football. A school wants to purchase 40 balls.
Let x be the number of the football and y be the total cost.
The equation for supplier A will be given as,
y = 2.59x + 85
At x = 40, the value of 'y' is given as,
y = 2.59 × 40 + 85
y = $188.6
The equation for supplier B will be given as,
y = 4.29x + 50
At x = 40, the value of 'y' is given as,
y = 4.29 × 40 + 50
y = $221.6
Supplier A has the lowest average cost per ball.
