Answer:x= -1, x=7
Step-by-step explanation: You will want to use the quadratic formula
X=-24)+/-[(-24)^2-4*4(-28)/2.4
Then separate the equations
x=24+32/8 And x=24-32/8
so x=7 and x= -1

The y-axis is the vertical axis/line out of the two perpendicular lines.
Vertical line/axis (y-axis)= │
Horizontal line/axis (x-axis)= ___
When you reflect Point A, it will be reflected across the vertical line (y-axis). This means that the point will be on the left side in Quadrant II (- , +).
A man has a certain unknown sum of money, 60% of that sum Is 4800 rupees. What is the sum of money?
Answers
Answer:
8000
Step-by-step explanation:
I did a simple way, I divided 4800 by 3 and got 1600, then multiplied 1600 by 5. Because 2x5 =10 (or 100%)
Answer:
x = 8000
Step-by-step explanation:
here's your solution
=> it is given that 60% of some unknown
number is 4800
=> now, let the unknown number be X
=> so, 60/100*X = 4800
=> X = 4800*100/60
=> X = 8000

Determine whether each given pair of endpoints lies on the same horizontal or vertical line.
If so, find the length of the line segment that joins the pair of points.
If not, explain how you know the points are not on the same horizontal or vertical line.
(3,-8) and (3,-1)
Answers
Given:
The pair of end points: (3,-8) and (3,-1).
To find:
Whether the given pair of endpoints lies on the same horizontal or vertical line.
Solution:
If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.
If the y-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same horizontal.
The given endpoints are (3,-8) and (3,-1).
From the given endpoints, it is clear that the x-coordinates of the endpoints are same. So, the given endpoints lies on the same vertical line.
The length of the line segment that joins the pair of points is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]D=\sqrt{(3-3)^2+(-1-(-8))^2}[/tex]
[tex]D=\sqrt{(0)^2+(-1+8)^2}[/tex]
[tex]D=\sqrt{(7)^2}[/tex]
[tex]D=7[/tex]
Therefore, the given endpoints lies on the same vertical line and the length of the line segment is 7 units.

Pizza Palace uses 0.5 pounds of cheese on each large pizza it makes. Part A write an equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x
Answers
Answer:
.5x= y
...............
An equation is formed of two equal expressions. An equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x is y=0.5x.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that Pizza Palace uses 0.5 pounds of cheese on each large pizza it makes. Therefore, an equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x can be written as,
Number of pounds of cheese=Amount of cheese used per pizza × Number of pizzas
y = 0.5 pounds × x
y = 0.5x
Hence, an equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x is y=0.5x.

Johnson’s Hardware randomly selects 125 of its customers and questions them to determine their overall customer satisfaction rating. The poll indicates 100 were completely satisfied, 15 were satisfied, and 10 were not satisfied at all. What percent of customers were either satisfied or completely satisfied? About how many of the 5000 customers were not satisfied at all?
Answers
Answer:
a. 92%
b. 4425
Step-by-step explanation:
So there are 5000 customers in total, and 100 were completely satisfied, and 15 were satisfied and 10 weren't satisfied a bit. so 100+15 is 115 so 115 people in total were satisfied out of 125 because there were 125, and 115+10 is 125 anyways. So 115/125 is .92, and you can convert that into a percentage, 92% of the 250 customers were satisfied so then 250*5 is 5000, so then just multiply 115 by 5 as well. You get 575. So 575 were satisfied out of the 5000 customers and 5000-575 are the people not satisfied, so 4425.
