Which graph represents 6x -2y> - 11

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Remember when using the inequality sign < or > the line will be dotted so we can immediately eliminate answer choices b and d

Now let us solve for y

6x-2y>-11

step 1 subtract each side by 6x

now we have

-2y>-11-6x

step 2 divide each side by -2

-11-/2=11/2

-6/-2=3

IMPORTANT -when you divide inequalities by a negative number you flip the inequality sign

So now we have

$y<3x+(11)/(2)$

See image below for reference

When the inequality is facing x the solutions are going to be on top of the line

hope this helps!

The probability that the dial stops on a red slice, when it is spun and stops on a slice at random is 1/5.

How to get probability of an event?

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A spinner with 10 equally sized slices has 2 red slices, 4 yellow slices, and 4 blue slices.

The total number of slices is 10 and the total number of favorable outcome to get a red slice is 2. Thus, the probability that the dial stops on a red slice is,

$P=(2)/(10)\nP=(1)/(5)$

Thus, the probability that the dial stops on a red slice, when it is spun and stops on a slice at random is 1/5.

Which ordered pair is a solution of the system? x + 4y = 19
y = -2x - 4

A. (3,4)
B. (7,3)
C. (-5,6)
D. (-2,0)

Answers

y = -2x - 4

x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5

y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6

What is unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

In rows of 4 there are 6 cards

and, he gave 7 cards to his friend.

So, he have

=6*4+ 7

=24+ 7

=31 cards

Hence, he have 31 cards.

Answers

Lets look at the info we have:-

18 rows
24 seats per row

Question:-
How many seats in all?

Solve:-

18 × 24 = 432
432 seats in the auditorium

CHECK OUR WORK:-

432 ÷ 18 = 24
We were RIGHT!!!

So, there are 432 seats in the auditorium.

Hope I helped ya!!! xD

u will multiply 18rows x 24seats = 432 seats
