Point slope form, y-y1 = m(x-x1)
Here, y1 = -1, x1 = 4, m=8
so, it would be: (y+1) = 8(x-4)
Answer:
I. Ella packed 70 books more than Ray.
II. Ray packed 580 books.
III. Ella packed 650 books.
Step-by-step explanation:
Given the following data;
Ray = 29 boxes of 20 books
Ella = 26 boxes with 25 books
To find the total number of books packed by Ray;
Total for Ray (Ray packed) = 29 * 20
Total for Ray = 580 books.
To find the total number of books packed by Ella;
Total for Ella (Ella packed) = 26 * 25
Total for Ella = 650 books.
Next, we find the difference between the books packed by Ella and Ray;
Difference = Ella - Ray
Difference = 650 - 580
Difference = 70 books
I think its 222064 i'm pretty sure it's correct
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>Inequality</u>: (x-1)(x+2)(2x-7)≤0
<h3>Solution: </h3>
<u>If we solve the corresponding equation (x-1)(x+2)(2x-7)²= 0, we get roots </u>
<u>We need to consider the following 4 intervals: </u>
- (−∞; −2), [−2; 1], (1; 3.5), (3.5; ∞)
<u>1st interval</u> (−∞; −2)
- The expression (x-1)(x+2)(2x-7)² is positive as two of the multiples are negative and one is always positive (square number), and therefore does not satisfy the inequality.
<u>2nd interval</u> [−2; 1]
- The expression is negative as only one of the multiples is negative, and therefore the interval (−1; 2) satisfies the inequality.
<u>3rd interval</u> (1; 3.5)
- The expression is positive as all the multiples are positive. Therefore, the interval (1; 3.5) also does not satisfy the inequality.
<u>4th interval</u>
- The expression is positive as above, and therefore also does not satisfy the inequality.
<u>So, the answer to the inequality is:
</u>
Answer:
2
Step-by-step explanation:
3 * -2 = -6
-6 +5 = 1
-2 * -1 = 2
