Answers

Answer:

I think that it could be A, or the third choice.

We need to see which points are solutions for the given system of inequalities, thus the solutions are points B and L.

What is inequality?

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Solving a system of inequalities we have the system here;

y <-2x + 10

y < 1/(2x - 2)

A point is a solution of the system if and only if it is a solution for both inequalities.

Now, Shade the region below the like for x = 5.

y = -2(5) + 10

= -10 + 10

= 0

For x= 0

y = -2(0) + 10

= 0 + 10

= (0, 10)

The diagram is attached below.

So, only B and L are solutions for the system.

8 and 1/2 + 7 and 1/ fourth

Answers

Answer:

15 3/4

Step-by-step explanation:

8+7=15

1/2+1/4= 3/4

15+3/4

Answer:

15 3/4

Step-by-step explanation:

You need to have like denominators before you add so you need to find the LCM (least common multiple) of the two numbers. Then you have to find how much you have to multiply each number by to get the multiple. Then you just have to remember that whatever you do to the bottom you do to the top.

1. 8 1/2 + 7 1/4     This is your equation.

2. 8 2/4 + 7 1/4      The LCM of 2 and 4 is 4. You multiply by two in the bottom to get 4 so you multiply by 2 at the top. (This is talking about the first fraction).

3. 15 3/4    Then you just add as you would normally add without changing the denominators an simplifying if you need to. (You don't need to simplify for this equation).

I hope this helped you.

Answer:

c = 13

Step-by-step explanation:

c = 6(3) - 5

c = 13

Answer:

C. c=13

Step-by-step explanation:

This is how I figured it out:

1. I took the equation (c=6a-b) and I replaced the letters with the numbers given. (a=3 & b=5) so I got the new equation c=6(3)-5.

2. I used PEMDAS (parentheses, exponents, multiplication, division, addition and subtraction. Since we have multiplication and subtraction needed multiplication is shown before subtraction in PEMDAS so we would figure out 6(3) first which is equal to 18.

3. Now we have the new equation of c=18-5. Since subtraction is left we would take away 5 from 18 and now we have the final answer of 13. So the equation would now look like this: c=13. It's pretty obvious that c=13 that c has the value of 13.

Given, 12 is divided by 2/3 which is,

= (12)/(2/3).

= 12×(3/2)                            (we can flip the divisor to make it a multiplier)
