Step-by-step explanation:
i hope this helps
X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0
x = -7 or x = -1
Answer:
Nine of the times for the first race were at least 16 seconds
Step-by-step explanation:
Here we have from the scatter plot, the times are given as
Time Frequency
19 2
18 2
17 2
16 3
15 1
Therefore, total number of times that are above 16 seconds in the first race is
3 + 2 + 2 + 2 = 9
Therefore, the first option is correct
Answer:
e^6 ≈ 403
Step-by-step explanation:
You want the value of e^(4x-2) when x = 2.
<h3>Evaluation</h3>
Put 2 where x is in the expression and do the arithmetic.
e^(4·2 -2) = e^6 ≈ 403.429
The value of the expression is about 403.
Answer:
14 4/9 cans
Step-by-step explanation:
We need to add the cans used on Saturday and Sunday
10 7/9 + 3 4/6
We can simplify the fraction 4/6 by dividing the top and bottom by 2
10 7/9 + 3 2/3
To add, we need the fractions to have a common denominator of 9
10 7/9 + 3 2/3*3/3
10 7/9 + 3 6/9
Add the whole numbers 10 +3 = 13
Add the fractions 7/9 + 6/9 = 13/9
13/9 = 1 4/9
Move the whole part of the fraction to the whole numbers
13 + 1 + 4/9
14 4/9
