Answer:
- 2, 0, 2
Step-by-step explanation:
To find the terms in the sequence substitute n = 1, 2, 3 into the rule, that is
= (2 × 1) - 4 = 2 - 4 = - 2
= (2 × 2) - 4 = 4 - 4 = 0
= (2 × 3) - 4 = 6 - 4 = 2
The first three terms are - 2, 0, 2
Answer:
A=3√5
B=11√7
Step-by-step explanation:
5√5-2√5
5-2√5
3√5
B) 8√7+3√7
8+3√7
11√7
For this system of equation I used substitution:
Step 1: Every time you see a y in the equation y = 2x - 1 replace it with -4x - 19
-4x - 19 = 2x - 1
Step 2: Isolate x
(-4x + 4x) - 19 = (2x + 4x) - 1
-19 = 6x - 1
-19 + 1 = 6x + (- 1 + 1)
-18 = 6x
x = -3
Step 3: To solve for y replace x in the equation y = 2x - 1 with -3
y = 2(-3) - 1
y = -6 - 1
y = -7
(-3, -7)
Check:
-7 = -4(-3) - 19
-7 = 12 - 19
-7 = -7 --------------------------------> Correct!
-7 = 2(-3) - 1
-7 = -6 - 1
-7 = -7 --------------------------------> Correct!
Hope this helped!
There are 16 ounces in a pound, so to find the amount of ounces in a certain amount of pounds, all we have to do is multiply the amount of pounds by the amount of ounces there are in one pound.
9 * 16 = 144
There are 144 ounces in 9 pounds.
Hope that helped! =)
