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.

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

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

Answers

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

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.

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
