Step-by-step explanation:
12-(-2)=10 -6+14=8 1+5=6 -10+15=5
Answer: 0.57 hours each day or 34.28 minutes each day.
Step-by-step explanation:
1. You know that:
-Alejandra worked on the animal report for school for 4 hours in a week.
- A week has seven days.
2. Therefore, to calculate the number of hours she worked on the project each day (which you can call 
), you can divide the number of hours worked on in a week by 7 days.
3. Therefore, you obtain the following result:
Multiply the result by 60 to obtain the time in minutes, then:
Answer:
the correct estimate of the weight of Errol's backpack would be 33
Step-by-step explanation:
you just need to add 10 and 23.
k = 5
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Since the coefficient of the x² term is 1 then
add/ subtract (half the coefficient of the x-term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5
Answer:
x < 4
OR
x > - 2.25
= 4 > x > - 2.25
Step-by-step explanation:
5x - 19 < 1
5x < 1 + 19
5x < 20
x < 20/5
x < 4
OR
- 4x + 3 < - 6
- 4x < - 6 - 3
- 4x < - 9
x > 9/- 4
x > - 2.25
