Solve equations using general formula​

Mathematics
1 answer:
jolli1 [7]3 years ago
5 0

Answer:

Step-by-step explanation:

Sorry I only know what general form is, not general formula.

First, subtract 2 from each side of 4x^2+10x=2

4x^2+10x-2=0

Divide by 2

2x^2+5x-1=0

Now use quadratic formula

(-5±√33)/4

You can also complete the square to solve the answer.

Answer:

5) a

6) a

7) b

8) d

9) a

10) b

11) c

12) a

Step-by-step explanation:

When it asks for range it is asking for the y values so when you plug in numbers such as 0,1,2 into the equation the y values you get are {0,90,180..}

Overall slope can be found by taking the x and y values of the two given points.

((y value of the second point)-(y value of the first point))/((x value of the second point)-(x value of the first point))

Using (1,2) and (-2, 5) you can do this by plugin in the numbers (5-2)/(-2-1)

So the slope will be 3/-3 = -1

Once you find the slope you can use this to find the equation of a line by pluging in values into y=mx + b

m = slope

y = use this from the points given

x = use this from the points given

Given 4x - y = 32, find:<br> a.) x-intercept<br> b.) y-intercept<br> c.) slope
Rashid [163]
You always want to get y by itself and in the form y = mx + b. So first, subtract 4x from both sides to get -y = -4x +32
You also want to get rid of that negative sign. That’s easy, divide everything by negative 1 to get:
y = 4x - 32

We can see the slope is just 4 and the y intercept is -32. The y-intercept is when x equals zero, you’ll get -32 if you do so. The x-intercept is now when y equals zero. Now solve for x. You get 4x = 32, divide by 4 to get 8

a.) 8
b.) -32
c.) 4

A total of 432 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student t
dybincka [34]

Answer:

144 tickets.

Step-by-step explanation:

So first we have to take the total amount of tickets sold and divide that by 3 (because students bought 2/3 of those tickets and adults bought 1/3 of those tickets). So we get the answer of 144. So that means that the adults bought 144 tickets and the students bought 288 tickets.
