Using the quadratic formula, the solutions to a quadratic equation are given by (equation is in image)

Find the values of a, b and c
a =
b =
c =

Answers

Answer:

a = -3

b = 3

c = 4

Step-by-step explanation:

Let's do this the long way!

[tex]x = \frac{-3 \pm\sqrt{3^2 - 4 \times (-3) \times 4}}{2 \times (-3)}\\-6x = -3 \pm\sqrt{3^2 - 4 \times (-3) \times 4}\\-6x + 3 = \pm\sqrt{3^2 - 4 \times (-3) \times 4}\\(-6x + 3)^2 = 3^2 - 4 \times (-3) \times 4\\36x^2 - 36x + 9 = 9 + 48\\36x^2 - 36x - 48 = 0\\3x^2 - 3x - 4 = 0[/tex]

So a = 3, b = -3, and c = -4

HOWEVER:

When you look at the terms in the solution originally given, the are all the negatives of what we see here.  That however makes sense, as we can simply multiply both sides of the equation to get the results they used:

[tex]3x^2 - 3x - 4 = 0\\-1(3x^2 - 3x - 4) = -1(0)\\-3x^2 + 3x + 4 = 0[/tex]

Four vertices of a rectangle are A(−3, −5) , B(−1, −5) , C(−1, −1) , and D(−3, −1) . Use the Segment tool to draw the four sides of the rectangle.

Answers

Answer:

well, I don't have the computer in front me with this question on it, but i can explain how you would do it.

all points, or in this case vertices, are written like this : (x , y)

the x-axis is the one that lies flat and the y-axis is the one going up and down.

in this graph, the y-axis and x-axis are more than likely not centered. so where the y-axis intersects the x-axis is known as the origin. you will start at the origin for plotting all points.

to plot point A : start at the origin and count to the left 3, and then down 5 and thats point A

for point B : start at the origin, count left 1 and then down 5, that's point B

point C : start at the origin, count left 1 and then down 1, that's point C

point D : count left 3 and then down 1, that's point D

after plotting the points, you just need to play "connect the dots" and make the shape a rectangle.

Start at point A, go right point B, up to point C, left to point D then down back to point A again

The state fair is a popular field trip destination. This year the senior class at High School A and the

filled 8 vans and 8 buses with 240 students. High School B rented and filled 4 vans and 1 bus with 54
students. Every van had the same number of students in it as did the buses. Find the number of students
in each van and in each bus.

Answers

Answer:

8 students in a van and 22 in a bus

Step-by-step explanation:

lets use V as the number of students in each van and B as the number in each bus. hs A has filled 8 vans and 8 buses with 240 students in total so 8*V+8*B=240. We can divide by 8 and we will get that V+B=30 so B=30-V. hs B rented 4vans and 1 bus for 54 students so 4*V+1*B=54. we alredy know that B=30-V so we can substitute that in the 2nd equation so 4*V+30-V=54. simplify and we'll get that 3V=24, V=8 and B=30-V=30-8=22
