We have been given 4 points 
. We are asked yo plot these points on coordinate plane and find the area of the figure.
Upon plotting our given points, we will get a rectangle as shown in the attached file.
We can see that the width is 5 units that is difference between y-coordinates of point 
.
We can see that the length of rectangle is 6 units that is difference between x-coordinates of point 
.
We know that area of rectangle is length times width.
Therefore, the area of the figure would be 30 square units.
Answer:
32.
Step-by-step explanation:
39 - 7 = 32
32 + 7 = 39
Brielle scored 32 points.
I hope this helped! :) Have a nice day.
Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
You can fir 8x8x8 cubes in the carton, that means you can fit 512 cubes in the carton.
the total cost would be, 0.25 x 512 = $128
Answer:
Two solutions
Step-by-step explanation:
This is a quadratic equation in the form y = ax² + bx + c.
For quadratic equations, you can find solutions using the quadratic formula:
.
To find the number of solutions, <u>you only need what's inside the square root</u>. We call it the "<u>discriminant</u>" because lets us know the number of solutions without solving.
If b²- 4ac > 0, two solutions. (greater than)
If b²- 4ac < 0, no solutions. (less than)
If b²- 4ac = 0, one solution. (equal to)
y = ax² + bx + c
y = -3x² + x + 12
a = -3 b = 1 c = 12
<u>Substitute into the discriminant</u>
b²- 4ac
= 1² - 4(-3)(12)
= 1 - (-144)
= 145 > 0
b²- 4ac > 0 Discriminant greater than 0
Therefore, there are two solutions.
