Answers

Answer 1

Answer:

two

Step-by-step explanation:

If the discriminant of a quadratic equation is 12 then it has two distinct real roots. That 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.

Answer 2

Answer:

two

If the discriminant of a quadratic equation is 12 , then it has two distinct real roots. Note that 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.

Step-by-step explanation:

you woud place the variable (letter) representing the number of weeks they worked by the amount they get paid each week then, you would add to whoever gets an extra amount of money, the y - intercept or in this case the extra 18 dollars one of them gets paid to whoever got paid that amount of extra money. :)

Answers

Answer:

The answer is x=-1/7

Step-by-step explanation:

11-6x-7-8x=6

Combine like terms

11-7-6x-8x=6

4-14x=6

4-4-14x=6-4

-14x=2

To find x divide both sides by -14

-14x/-14=2/-14

x=-1/7

A boat leaves Astoria and travels upstream on the Columbia river for 5 hours. The return trip only takes 3.6 hours because the boat travels 4 miles per hour faster downstream due to the current. How far does the boat travel up the Columbia? Suppossed to solve as an in equality?

Answers

Answer:

10.285 miles

Step-by-step explanation:

Given that:

Upstream travel time = 5 hours

Return trip travel time = 3.6 hours

Let upstream travel speed = x mph

Downstream travel speed = x + 4 mph

Distance = speed * time

Upstream distance = x * 5 = 5x

Downstream distance = (x + 4) * 3.6

5x = (x + 4) * 3.6

5x = 3.6x + 14.4

5x - 3.6x = 14.4

1.4x = 14.4

x = 10.285714

x = 10.285 miles

Find the irrational number between 0.3101 and 0.3333

Answers

Answer:

π/10

Step-by-step explanation:

Irrational Numbers

The irrational numbers are identified because, unlike rational numbers, they cannot be expressed as fractions, i.e., as the result of a division between two integers.

If a number is expressed with a limited number of decimals, it's always possible to write it as a rational.

For example, number 1.2319 can be written as 12319/10000.

Even if the number has an unlimited decimal expression, it could be expressed as rational if the decimal part is periodic. Number 2.33333... is rational because it's equivalent to the fraction 7/3.

We need to find an irrational number between 0.3101 and 0.3333.

Any number within the range with unlimited non-periodic decimals will do:

0.3189567363.... is a good example.

We'll choose the number

π/10 since π is a known irrational number and π/10=0.3141592... lies in the given interval.

Which equation describes the line with slope 5, that contains the point (-2, 4)?
a: y = 5x - 22
b: y = 5x - 2
c: y = 5x + 4
d: y = 5x + 14

Answers

Answer:

C

Step-by-step explanation:

Answer:

D.)  y=5x+14

Step-by-step explanation:

point slope form: y-y1=m(x-x1)

y1=4, m=5, x1=-2

y-4=5(x+2)

distribute 5

y-4=5x+10

add 4 to both sides

y=5x+14

[tex] \frac{x}{2} + x = 144[/tex]

[tex]2( \frac{x}{2} ) + 2(x) = 2(144)[/tex]

[tex]x + 2x = 288[/tex]

A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?

Answers

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = [tex]\frac{k-1}{0+1}[/tex] = k - 1 = 8 ( add 1 to both sides )

k = 9

For every $9 invested in company A, $2 is invested in company B. Stacey quizzes her children, Krista and Kevin, about how much money she will invest in company A if she invests $24 in company B. Krista and Kevin used two different methods to arrive at the answer to Stacey's problem. Let's see who found the correct answer and how. You'll answer some questions along the way.

Answers

Answer:

$108

Step-by-step explanation:

From the above question, we have the proportion:

Company A/Company B

= $9/$2 = x/x24

The next step is : We Cross Multiply

2x = $24 × $9

x = $24 × $9/2

x = $108

Therefore, she will invest in $108 company A if she invests $24 in company B.

Which of these tables best represents the equation y = 5x – 8

What is a Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given a linear equation y = 5x - 8

As we can see that this equation has a slope of 5 and a y-intercept of -8

To ease the process we will calculate the value of y at different values of x:

For x = 0 ,

y = 5 * 0 - 8 = -8

For x = 1

Y = 5-8 = -3

For x = 2

Y = 5*2 - 8

y = 2

For x = 3

y = 5*3 -8

y = 7

for x = 4

y = 20 *8

y = 12

Since only table C is satisfying the situation.

therefore, The best and only represents the equation y = 5x – 8 is done in table C.
