A is the poin 3,5 and b is the point 0,k if the distance of ab is 5 units find the possible value of k
Answer:
K is either 9 or 1
Step-by-step explanation:
Sqrt((0 - 3)² + (k - 5)²) = 5
Square both sides
(0 - 3)² + (k - 5)² = 5²
(0 - 3)² + (k - 5)² = 25
-3² + (k - 5)² = 25
9 + (k-5)(k-5) = 25
9 + k² - 5k - 5k + 25 - 25 = 0
k² - 10k +9 = 0
k² - 9k - k + 9 = 0
k(k - 9) - 1(k - 9) = 0
k - 1 = 0 ; k = 1
k - 9 = 9; k = 1
K = 9 or k = 1
K is either 9 or 1

This is a Desmos question please help me
Answer:
B
Step-by-step explanation:
If the 2 lines were parallel, then
5x - 10 = 70 ( alternate angles )
Add 10 to both sides
5x = 80 ( divide both sides by 5 )
x = 16
For the 2 lines to be parallel then x = 16
Answer:
B.16
Step-by-step explanation:
First I would Make an equation:
For example set (5x-10)=70
Add 10 to both sides:
5x-10+10=70+10
Simplify:
5x=80
Divide both sides by 5:
5x/5=80/5
simplify:
x=16
In conclusion the answer is B.16
Trevon reads from his book every week. The first week he read 15 pages, the second week he read 21 pages, the third week he read 33 pages, and the fourth week he read 51 pages. If the same pattern continues, how many pages will he read in each of the next 3 weeks?
Answer:
Trevon would have read 183 pages by then.
Step-by-step explanation:
You multiply by six each week. For example,
Week 1: 15+6=21
Week 2: 21+12=33
Week 3: 33+18=51
Week 4: 51+24=75
Week 5: 75+30=105
Week 6: 105+36=141
Week 7: 141+42=183
