−2x+12y=18? enter your answer in the box (_,0)

Mathematics
1 answer:
KengaRu [80]3 years ago
3 0

Answer:

The answer is x = -9. (-9,0)

Step-by-step explanation:

first put the equation into standard slope intercept form

y = mx + b

12y = 2x + 18

The problem says the pair is (_,0). so we substitute 0 for y.

12(0) = 2x + 18

0 = 2x + 18

solve for x

- 18 = 2x

x =  -  \frac{18}{2}

x =  - 9

Which of the following shows the graph of y = 2 l n x On a coordinate plane, a curve starts at (0, negative 2) in quadrant 4 and
enot [183]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Given:

f(x)= 2^{-x}=\frac{1}{2^x}

  • In the above choices it is clearly defined from the above equation that output rises in the first quadrant, the value of f(x) tends to be zero and increases into another second quadrant.
  • For x = 0, y, once again, has become 1, that is the function passes the y platform at (0,1).
  • Therefore an exponential function reaches y = 0 in quadrant 1 on a coordinate plane and rises into quadrant 2.
  • (0,1) stage is the temperature at which the y-axis intersects.

Emily added 5 grams of water into 20 grams of 50% salt solution.
atroni [7]
Answers:
She made ___25___ grams of ___40___% salt solution

------------------------------------------------------------------

The given info "20 grams of 50% salt solution" tells us that we have 10 grams of pure salt
Since 50% of 20 = 0.50*20 = 10
Put another way, we have 10 grams of pure salt out of 20 total so 10/20 = 0.50 = 50% salt solution

The 20 grams of solution updates to 25 grams of solution when we add the 5 grams of water
We don't add any salt, assuming this water is fresh water

So we still have 10 grams of pure salt out of 25 grams now
10/25 = 2/5 = 0.40 = 40% is the new salt concentration

Please help solve the problem below.
ivann1987 [24]

Answer:

1. x = 2

2. x = 5

3. x = 8

4. x = 28

5. x = 13

6. x = 11

7. x = 0

8. x = 72

9. x = 6

10. x = 38

Step-by-step explanation:

hope that helps!

1. subtract 6 on both sides

2. add 3 on both sides

3. divide both sides by 2

4. multiply both sides by 2

5. add 8 on both sides

6. subtract 9 on both sides

7. add 5 on both sides

8. multiply both sides by 6

9. divide both sides by 4

10. add 18 on both sides
