Answer:
-31
Step-by-step explanation:
Formula for finding the discriminant:
b² - 4ac
Let's identify our values.
a = -2
b = 1
c = -4
Time to plug in our values.
1² - 4(-2)(-4)

Match each event to the likelihood of its occurrence. rolling a six-sided die and getting a 7 randomly selecting a girl from a team of 14 boys and 4 girls randomly selecting a short straw from a set of 12 short straws and 12 long straws picking a bird from a list of 20 bird species and 6 other animals likely arrowRight impossible arrowRight unlikely arrowRight neither likely nor unlikely arrowRight
A six sided die has numbers 1 through 6 so getting a 7 is impossible so the probability would be 0 (impossible)
14 + 4 = 18 total boys and girls
Picking a girl would be 1/18 this is low so ( unlikely)
12 short and 12 long straws = 24 total straws. Picking a short one would be 12/24 = 1/2 this is in the middle ( neither likely nor unlikely)
20 + 6 = 26 total animals
Picking a bird = 20/26 = 10/13, this is high ( likely)

Answer:
is it asking which one is a y coordinate?
Answer:
Q'(5, -3), R'(4, -1), S'(0, -2), T'(0, -5)
Step-by-step explanation:
Reflecting across the y-axis causes the x coordinate of a point to change to its opposite. So in terms of x and y: (x, y) ⇒ (-x, y)
Q(-5, -3) ⇒ Q'(5, -3)
R(-4, -1) ⇒ R'(4, -1)
S(0, -2) ⇒ S'(0, -2)
T(0, -5) ⇒ T'(0, -5)

For all of the graphs:
Start the point on the number that I got from the inequality.
A filled circle means:
Greater than or equal to or less than or equal depending on where the line goes.
A hallow circle means:
Greater than or less than also depending on where the line is pointed towards too.
In order to graph an inequality you have to find and simply first then graph it.
For example on number 1, K ≤ -4.
Let's graph!
As you can see I filled in the circle and started at the point, -4.
Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.
I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.
A factory makes toy cars. For the past 8 days, the factory made 787 toy cars each day. How many toy cars the factory made?
Answer:
6,296
Step-by-step explanation:
Multiply 8 by 787
Answer:
6,296
Step-by-step explanation:
The equation for the problem would be:
y = 787x
Let x be the number of days:
y = 787(8)
So the total toy cars for the past 8 days is:
y = 6,296
