This equation is in vertex form. Vertex form is y=a(x-h)^2+k, where (h,k) is the vertex. In this equation, h= -3, and k= -4. So, the vertex would be at (-3,-4). A tells us if the parabola will be positive or negative. In this case, it is positive, so the parabola opens upward. Then, you can solve for x-intercept by letting y=0 and solving for x. Then, you can find the y-intercept by setting x=0 and solving for y. Finally, graph the parabola.

A rucksack can hold a maximum of 6 kg.
ratelena [41]

Answer:

9 textbooks!

Now, 6/0.68

That is 8.82 ( Round off = 9 textbooks)

Use substitution to solve the system of linear equations. In your final answer, include all of your work. y = -3x + 4 and x + 1/
FrozenT [24]

Answer:

y = -3x +4

Step-by-step explanation:

Using the expression for y, we can substitute that into the second equation:

... x + (1/3)(-3x +4) = 4/3

... 4/3 = 4/3 . . . . . simplify (True for any value of x.)

<em>These equations are dependent and have an infinite number of solutions</em>.

A survey of students in the junior class at Avery's high school provided the following information:
Oduvanchick [21]

Avery can explain to her school principal that 85% of juniors think there is a lot of homework because several indicators have increased.

<h3>What is an indicator?</h3>

An indicator is a datum that is taken as a reference to analyze the evolution or change of a fact over time. In this case, the indicators would be:

  • Weekly hours used to do homework
  • Number of students with work for after school.

According to the information, it can be inferred that 85% of Junior students consider that there is an increase in homework because there were the following changes compared to last year:

  • Increase in hours spent on after school homework, last year the average was 5 hours, this year it is 8 hours.
  • Increase in the number of students with after school jobs, last year it was 135 students, this year it is 215 students.

From the foregoing, it can be inferred that the number of homework has increased in Junior students and that is why now 85% of them consider that homework has increased.
