Answer:
3, 1, - 1, - 3 and - 15
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the rule, that is
a₁ = 5 - 2(1) = 5 - 2 = 3
a₂ = 5 - 2(2) = 5 - 4 = 1
a₃ = 5 - 2(3) = 5 - 6 = - 1
a₄ = 5 - 2(4) = 5 - 8 = - 3
The first 4 terms are 3, 1, - 1, - 3
For 10th term substitute n = 10 into the rule
a₁₀ = 5 - 2(10) = 5 - 20 = - 15

7x - 2(3x - 5) = 26
Answers
Answer:
x=16
Step-by-step explanation:
7x−2(3x−5)=26
Use the distributive property to multiply −2 by 3x−5.
7x−6x+10=26
Combine 7x and −6x to get x.
x+10=26
Subtract 10 from both sides.
x=26−10
Subtract 10 from 26 to get 16.
x=16
Graph if needed:
Answer:
x = 16
Step-by-step explanation:
7x - 2(3x - 5) = 26
7x - 6x + 10 = 26
7x - 6x + 10 - 10 = 26 - 10
x = 26 - 10
x = 16

Answer:
C. x² + (y + 16)² = 15Step-by-step explanation:
Equation of circle:
(x - h) + (y - k) = r², where (h, k) is the center and r is the radiusWe have:
h = 0, k = -16, r = √15Substitute the given into the equation above and get the equation of the given circle:
(x - 0)² + (y - (16))² = (√15)² ⇒x² + (y + 16)² = 15Correct choice is C

Kate wanted to sell a box of candy bars to raise money for her team. She sells 1/4 of the box at school. And 1/2 of the box to her neighbors. What fraction of the candy bars dose kate still have to sell. Put your answer in simplest form
Answers
Answer: 1/4
Step-by-step explanation:
Fraction of the box of candy bars sold at school = 1/4
Fraction of the box of candy bars sold to neighbor = 1/2
Therefore, the fraction that she has sold already will be:
= 1/4 + 1/2
= 1/4 + 2/4
= 3/4
The fraction of the candy bars that Kate still have to sell will be:
= 1 - 3/4
= 1/4
Kate has 1/4 candy bars left to sell

Find x and y with ray theorem
Answers
Answer:
x = 12 and y = 9
Step-by-step explanation:
Using the similarity theorem to fid the value of x and y
16/x = 16+6/16.5
16/x = 22/16.5
22x = 16*16.5
22x = 264
x = 264/22
x =12
Similarly
24/x = 24+y/16.5
24/12 = 24+y/16.5
2 = 24+y/16.5
24+y = 2 * 16.5
24+y = 33
y = 33-24
y = 9
Hence x = 12 and y = 9

Answer:V= 1526.8m3
Step-by-step explanation: pi (9)2(6)
A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.
What is a cylinder?A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.
Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,
Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³
Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.
