Answer:
9
Step-by-step explanation:
x didn't change in value, y changed by 9
the distance between the two points is 9
Answer:
mean: 8.9, median: 9, mode: 3, range: 14, standard deviation: 5.1
Step-by-step explanation:
The mean is all the numbers added up, divided by how many numbers there are. To get the median you arrange the numbers biggest to smallest and find the middle number.
Start at the beginning. 17 pages times 120 sentences is the first thing.
17 x 120 = 2040. So she has to read 2,040 sentences. If we now divide 2.040 by 14 pages/minute, we shoud get
2,040 divided by 14 = 145.7
The last thing to do, is changes those minutes into hours by dividing by 60.
2.42 hours.
The question is asking that X times 38% will equal to 247. So we set up the equation:
Then, we multiply both sides by
and we get the answer is
650
Answer:
(- 3, 0 ) and (1, 0 )
Step-by-step explanation:
Given
y =2x² + 4x - 6
To find the x- intercepts let y = 0, that is
2x² + 4x - 6 = 0 ← divide all terms by 2
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
The x- intercepts are (- 3, 0 ) and (1, 0 )
