Rowan reads at a constant rate of 1.5 pages per minute and has already
saul85 [17]

Using linear functions, it is found that Rowan and Kennedy will have read the same number of pages in 10 minutes.

What is a linear function?

  • A linear function is modeled by:

y = ax + b

In which:

  • a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

For Rowan, we have that:

  • He has already read 20 pages, hence the y-intercept is b = 20.
  • He reads 1.5 pages per minute, hence the slope is a = 1.5

Then:

y_R = 1.5x + 20

For Kennedy, we have that:

  • He has already read 25 pages, hence the y-intercept is b = 25.
  • He reads 1 page per minute, hence the slope is a = 1

Then:

y_K = x + 25

They will have read the same number of pages after x minutes, for which:

y_R = y_K

Then:

1.5x + 20 = x + 25

0.5x = 5

x = \frac{5}{0.5}

x = 10

Question 4 of 10
Tresset [83]

Answer:

4. 2. 2. 4. 5. 5. 10. 15.

Step-by-step explanation:

x−1 x+1. = ∞. 2. All the vertical asymptotes of the function f(x) = x2 − 1 x3 − 9x are at. Answer: x = 0 and x = ±3. Solution: Write f(x) = g(x) h(x) ... x→a− f(x) or lim x→a+ f(x) is ±∞. For a = 0, lim x→0+ f(x)=+∞. For a = 3, lim x→3+ f(x)=+∞. ... 5. 10. Which of the following gives the graph of f (x)

1 7/10 x 2/3 what is the product
Ludmilka [50]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{1 \frac{2}{15}}}}}}

Step-by-step explanation:

\sf{1 \frac{7}{10}  \times  \frac{2}{3} }

Convert the mixed number into improper fraction

\longrightarrow{ \sf{ \frac{10 \times 1 + 7}{10}  \times  \frac{2}{3}}}

\longrightarrow{ \sf{ \frac{17}{10}  \times  \frac{2}{3}}}

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term

\longrightarrow{ \sf{ \frac{17 \times 2}{10 \times 3}}}

\longrightarrow{ \sf{ \frac{34}{30}}}

\longrightarrow{ \sf{ \frac{17}{15} }}

Convert the improper fraction into mixed number

\longrightarrow{ \sf{1 \frac{2}{15} }}

Hope I helped!

Best regards! :D

A triangular course for a canoe race is marked with buoys. the first leg is 3/10 mi, the second leg is 1/2 mi, and the third leg
igomit [66]

Answer:

1 1/5 mi

Step-by-step explanation:

We need to add the three legs together

3/10 + 1/2 + 2/5

The common denominator is 10

3/10  =3/10

1/2 *5/5 = 5/10

2/5 *2/2 =4/10

3/10 + 5/10+4/10 = 12/10

10/10 = 10/10+2/10 = 1+2/10  = 1 1/5 mi
