Answer:

  J- There are no real factors.

Step-by-step explanation:

For quadratic ax^2 +bx +c, the discriminant is ...

  d = b^2 -4ac

  d = (-4)^2 -4(9)(1) = 16 -36 = -20

When the discriminant is negative, there are no real factors.

what is the equation of the given line ( 1,5) and (3,5)
A.)Y=5

B.)X=3

C.)Y=3

D.)X=1

Answers

Answer:

A) y = 5

Step-by-step explanation:

Points: (1, 5) and (3, 5)

Slope:

m=(y2-y1)/(x2-x1)

m=(5-5)/(3-1)

m=0/2

m = 0

Since 0 is the slope, that means there's no slope.

y - y1 = m(x - x1)

y - 5 = 0(x - 1)

y - 5 = 0

y = 5

If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.

Answers

Answer:

So the next time they will leave together is 4:24 pm

Step-by-step explanation:

Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.

The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.

Factors of 6 = 2*3

Factors of 8= 2*2*2

In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M

L.C.M= 2*2*2*3= 24 minutes

So the next time they will leave together is 4:24 pm

The sum of the numbers 13 + 13 + 13 is 39.

What is Addition?

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given expression is,

13 + 13 + 13

Here 13 is added to itself three times.

When 13 added to 13, we get 13 + 13 = 26

Again if we add the number 13 to 26, we get 13 + 26 = 39

13 + 13 + 13

= 26 + 13

= 39

This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.

Hence the number 13 added to itself three times gives 39.

If the pointer in the figure is spun​ twice, find the probability that the pointer lands on yellow ​(Y​) both spins.

Answers

Answer:

0.25

Step-by-step explanation:

Well assuming the result of the spin is uniformely random, the yellow area will come up 1/2 of the time (because it takes up 1/2 of the figure).

If it needs to land on yellow both times in two spins, we can take it step by step.

The probability it lands on yellow after the first spin is 0.5

The probability it lands on yellow and then lands on yellow again is 0.5 * 0.5 = 0.25

Think of both spins as 50% yellow, 50% non-yellow

We have 4 options

yellow, yellow

yellow, non-yellow

non-yellow, yellow

non-yellow, non-yellow

Each option is equally probable, so the probability of "yellow, yellow" is 0.25

Can someone plz help me

Answers

Answer:

41 degrees

Step-by-step explanation:

All three angles in a triangle must add up to 180 degrees. The picture already tells you that B is 63 degrees. This means A and C should both add up 117 degrees. If A is 2x+8 and B is x+7, then A+B is 3x+15. This means that 3x+15 is equal to 117 degrees.

3x + 15 = 1173x = 117 - 153x = 102x = 102/3x = 34

Now that we know that x is 34, we plug it in. X + 7 becomes 34 + 7 degrees which is equal to 41 degrees.

Answer:

It seems that you are trying to find the length of hair of Florencia on Tuesday.

Given that length of the hair of Florencia on Monday = h centimeters

On Tuesday, she got hair cut.

So new length of the hair of Florencia on Tuesday = 75% of Monday value

= 75% of (h)

= 0.75* (h)

= 0.75h

Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.

What is the remainder in the synthetic division problem below?
1|4 6 -3
A. 3
B. 7
C. 5
D. 9

Answers

The correct option is (b) i.e. In the given synthetic division, the remainder will be 7.

What is Remainder ?

The remainder is what "remains" after an activity is finished, as its name implies. In mathematics, it is impossible to divide 17 by 3 precisely. The leftover after division is the number 2, which is set aside.

Given : 1   |    4 6 -3

If we solve it further, we get

                               1   |    4 6 -3

                                   |        4  10

                                   |    4 10  7

Steps :

firstly we will write 4 as it is .

we will multiply 1 by 4 and write it in the second place, then we will add 6 and 4.

Similarly, we will multiply 1 by 10 and write it in the third place, then we will add -3 and 10 and finally get 7 as residual.

here, after solving, we get 7 in the end which is set aside.

So, the remainder will be 7.

Hence, the correct option is (b).
