The equation of the parabola with x-intercepts (2,0) and (3,0) and y-intercept (0,-1.2) will be y = (-1/5)(x - 2)(x - 3).
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
The equation of a parabola is written as,
y = a(x - b)(x - c) here b and c are two x-intercepts while (a,y) is the y-intercept.
As per the given,
x-intercept = (2,0) and (3,0)
y-intercept = (0,-1.2)
y = a(x - 2)(x - 3)
-1.2 = a(0 - 2(0 - 3)
a = -1/5
Thus,
y = (-1/5)(x - 2)(x - 3)
Hence "The equation of the parabola with x-intercepts (2,0) and (3,0) and y-intercept (0,-1.2) will be y = (-1/5)(x - 2)(x - 3)".

Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D. Side B C is 3.8 units. Side A prime B prime is 15 units and side B prime C prime is 9.5 units. What is AB? 6 units 7.6 units 9.5 units 12 units
Answers
Answer:
[tex]AB = 6[/tex]
Step-by-step explanation:
Given
[tex]BC = 3.8[/tex]
[tex]A'B' = 15[/tex]
[tex]B'C' = 9.5[/tex]
Required
Determine the length of AB
Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:
[tex]A'B' : AB = B'C' : BC[/tex]
Substitute values for A'B', B'C' and BC
[tex]15 : AB = 9.5 : 3.8[/tex]
Express the ratio as fractions:
[tex]\frac{AB}{15} = \frac{3.8}{9.5}[/tex]
Multiply through by 14
[tex]15 * \frac{AB}{15} = \frac{3.8}{9.5} * 15[/tex]
[tex]AB = \frac{3.8}{9.5} * 15[/tex]
[tex]AB = \frac{3.8* 15}{9.5}[/tex]
[tex]AB = \frac{57}{9.5}[/tex]
[tex]AB = 6[/tex]

what is the solution to the given system of equations. y = 4x - 3
y = -X- 13
Answers
y = -x - 13
Since both equations equal y, we will just substitute both equations to equal each other.
4x - 3 = -x - 13
+x on both sides
5x - 3 = -13
+3 on both sides
5x = -10
/5 on both sides
x = -2
Substitute x = -2 into one of the equations.
y = -x - 13
y = -(-2) - 13
y = 2 - 13
y = -11
To check answer, plug in both x and y values into one of the equations.
y = -x -13
-11 = -(-2) - 13
-11 = 2 - 13
-11 = -11
Answer:
x = -2
y = -11
Segment AB falls on line 6x + 3y = 12. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD? They are parallel because they have the same slope of −2. They are parallel because they have the same slope of one half. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept. They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answers
The lines 6x + 3y = 12 and 4x + 2y = 8 lie exactly on top of one another because they have same slope and same y intercept.
What are the coincident lines?The lines which coincide or lie on the top of each other are called coincident lines.
When the two lines coincide to each other?Two lines coincide to each other when they have same slope and same y intercept.
According to the given question.
We have two equation of lines.
[tex]6x + 3y = 12...(i)[/tex]
And, [tex]4x + 2y = 8...(ii)[/tex]
The equation (i) can be written as
[tex]2x + y = 4[/tex]
And equation (ii) can be written as
[tex]2x + y = 4[/tex]
Since, both the lines have same slope and same y intercept. Therefore, the given two lines coincide to each other.
Hence, the lines 6x + 3y = 12 and 4x + 2y = 8 lie exactly on top of one another because they have same slope and same y intercept.

Four bags of dry dog food plus 9.5 pounds of dry cat food weigh pounds in all. How many pounds does each bag of dog food weigh?
Answers
Answer:
Each bag of dog food weighs 2 pounds
Step-by-step explanation:
Here is the complete question:
Four bags of dry dog food plus 9.5 pounds of dry cat food weigh 17.5 pounds in all. How many pounds does each bag of dog food weigh?
Step-by-step explanation:
From the question,
Four bags of dry dog food plus 9.5 pounds of dry cat food weigh 17.5 pounds in all.
Let the weight of one bag of dry dog food be x.
Then we can write that
4x + 9.5 pounds = 17.5 pounds
To determine x, subtract 9.5 pounds from both sides
4x + 9.5 pounds - 9.5 pounds = 17.5 pounds - 9.5 pounds
4x + 0 = 8 pounds
4x = 8 pounds
Divide both sides by 4
4x/4 = 8 pounds/4
x = 2 pounds
∴ The weight of one bag of dry dog food is 2 pounds.
Hence, each bag of dog food weighs 2 pounds.

At a club fundraiser a group of students washed 84 cars in one weekend. The next weekend, they washed 112 cars. What was the percent increase in the nunbers of cars washed?
Answers
Answer:
33.33%
Step-by-step explanation:
The computation of the percentage increase in the number of car washed is as follows;
= (Number of cars washed in next weekend - number of cars washed in one weekend) ÷ (number of cars washed in one weekend)
= (112 cars - 84 cars) ÷ (84 cars)
= 28 cars ÷ 84 cars
= 33.33%
