The y-intercept occurs when x = 0.
y = x^2 + 2x + 6
Let x = 0
y = 0^2 + 2 * 0 + 6
y = 6
Answer: 6

Y-intercept is a point when x=0,
so
y=x²+2x+6=0²+2*0+6=6
y=6
So y-intercept is (0,6)

Question
6x – 2y = 10 2x + 3y = 51 Solving the first equation above for y gives
Solution 1

Answer with Step-by-step explanation:

6x – 2y = 10

2x + 3y = 51

Solving the first equation above for y:

6x-2y=10

⇒ 2y=6x-10

dividing both sides by 2

y=3x-5

Putting value of y in second equation

2x + 3(3x-5) = 51

2x+9x-15=51

11x=51+15

11x=66

⇒ x=6

y=3×6-5

=18-5

= 13

Hence, solution is: x=6 and y=13

and  Solving the first equation above for y gives: y=3x-5

Solution 2
The answer is
x=6 and y=13

Question
Hello everyone, please explain this with details. Jay traveled from Miami to Jacksonville, a distance of 320 miles. He left Miami at 8:00 A.M., stopped for lunch for 30 minutes, and stopped for two 15 minute breaks at rest areas. He arrived in Jacksonville at 2:15 P.M. What was his average rate of speed during his travel time?
Solution 1
Travel from 8 AM to 2:15 PM is a total of 6 hours and 15 minutes. If you subtract the 30 minute lunch and two 15 minute breaks you are left with 5 hours and 15 minutes or 5.25 hours. To get his average speed divide 320 miles by 5.25 hours

320 ÷ 5.25 = 60.9 mph or 61 mph rounded to the nearest one.

Question
What is 644 divide by 8 times 8.
Solution 1
644 divided by (8 x 8) (8x8) equals 61 so 644 divided 61 equals 10.557377049
Solution 2
The answer would be 644 because you divided 8 which would equal 80.5 and then you multiply that by 8 you get 644. 
Question
A ________________ event has a 100% chance of occurring. Example: Picking a red ball from a bag of only red balls.
Solution 1

We have been given that probability of the even is 100%. In other words we can say that the probability is 1. It means that the event will certainly occur.

Now, we know that the highest value of probability is 1 and lower value is 0.

Mathematically, we can represents it as

0\leq P(E)\leq 1

If the probability is 0 then the event will never occur.

And if the probability is 1 then event will definitely occur.

Therefore, A certain event has a 100% chance of occurring.

Solution 2
Certain event is the answer
Question
**MARKING BRAINLIEST IF RIGHT AND IF YOU SHOW WORK** 3. Use the Fermi process to estimate the number of bricks needed to fill an empty bathtub. Show your work. My teacher said you can use approximate dimensions of the bricks and bathtub. He said use the easiest ones so that it will be easy to solve.
Solution 1
Bath tub: 60 x 30 x 18

brick: 8 x 4 x 2

fermi process:
(60 x 30 x 18) /  (8 x 4x 2)
             
 =  32,400 / 64

 = 506.25

 estimated as 500 bricks


Question
Which statement follows from the given theorem? Theorem: The diagonal of a parallelogram divides it into two congruent triangles. A. Diagonals of a parallelogram bisect opposite angles. B. Consecutive sides of a parallelogram are congruent. C. Consecutive angles of a parallelogram are congruent. D. Consecutive angles of a parallelogram are supplementary.
Solution 1

Answer with explanation:

Theorem : The diagonal of a parallelogram divides it into two congruent triangles.

Properties of parallelogram

1. Opposite sides are equal and parallel.

2. Diagonal bisect each other.

3. Opposite Angles are equal.

If you will look at the first three options

A:  Diagonals of a parallelogram bisect opposite angles.→→False(Alternate angles are equal)

B: Consecutive sides of a parallelogram are congruent.→→→False(Opposite sides are congruent)

C: Consecutive angles of a parallelogram are congruent.→→→False(Opposite angles are congruent)

D: Consecutive angles of a parallelogram are supplementary.→→→→True

For,any parallelogram, having vertices , A, B and C and D

Opposite sides are parallel, so

1.∠A + ∠B=180°

2.∠C + ∠B=180°

3.∠C+ ∠D=180°

4. ∠A + ∠D=180°

Option D

Solution 2

Answer:

Opposite sides of a parallelogram are congruent.
