<h2>Answer</h2>
x = 8 or x = 3
<h2>Explanation </h2>
1. Multiply A and C
24 * 1 = 24
2. Find two numbers that multiply to 24 but add up to -11
-8 * -3 = 24
-8 + -3 = -11
(x - 8)(x - 3)
3. Switch the signs to find the value of x
x = 8 or x = 3
Answer:
see explanation
Step-by-step explanation:
(8)
the common ratio r, of a geometric sequence is
r = 
= 
= ......
r = 
= 
= 8
(9)
The simplest way to evaluate the sum is to substitute k = 3, 4, 5, 6 into each term and sum them
(- 9 + 20) + (- 12 + 20) + (- 15 + 20) + (- 18 + 20)
= 11 + 8 + 5 + 2 = 26
X=2
y=2
3x2+6x2=18
3x2=6
6x2=12
12+6=18
Answer:
Part A:
x+y= 95
x = y+25
Part B : 35 minutes
Part C : No
Step-by-step explanation:
Eric plays basketball and volleyball for a total of 95 minutes every day
x+y= 95
Where:
x =the number of minutes Eric plays basketball
y= the number of minutes he plays volleyball
He plays basketball for 25 minutes longer than he plays volleyball.
x = y+25
System:
x+y= 95
x = y+25
Replacing x=y+25 on the first equation:
(y+25) + y =95
Solving for Y
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
Part C : No
if x = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Replacing y=60 on the other equation:
x = y+25
35 = 60+25
35 ≠85
