Answer:
oh sorry i dont know that im grade six sorry
Y=1
Explanation:
You have to plug 2+x into the y of the first equation. After you solve that you should get-1 as the answer for x so you plug -1 into the x of the second equation and the value of y would be 1.
Answer:
AB ≈ 7.08
Step-by-step explanation:
Cos θ = adjacent / hypotenuse
where θ = 20° , adjacent = 7 and hypotenuse = AB
cos 20 = 7 / AB
cos 20 × AB = 7
AB = 7/Cos 20
AB = 7 / 0.989
AB = 7.077
AB ≈ 7.08
Step-by-step explanation:
to find the sum of nth term
equation is
n/2 ( 2a + (n-1)d) where a is the 1st term and d is the common difference
5/2 ( 120 +( 4 × 31))
5/2 ( 120 + 124)
5/2 × 244
5 × 122 <em>dividing</em><em> </em><em>2</em><em>4</em><em>4</em><em> </em><em>by</em><em> </em><em>2</em>
