Answer:
<h2>my answer is 4x+6/2+2 </h2><h2>is 10.3221</h2>
Answer:
Step-by-step explanation:
t1 = a1
t2 = a1 + d
t3 = a1 + 2d
The sum is t1 + t2 + t3 = a1 + a1 + d + a1 + 2d = 3a1 + 3d
Second question
t1 = a1
t2 = a1 + d
t3 = a1 + 2d
t4 = a1 + 3d
...
tn = a1 + (n - 1)*d
Sum = (a1 + a1 + (n- 1)*d) * n / 2
Sum = (2a1 + nd - d) * n / 2
Sum = (2a1*n + n^2*d - nd) / 2
Answer:
Questions 1 and 3 already answered
<h3>Q2</h3>
<u>Angles 1 and 3 are corresponding angles and therefore have same value:</u>
Y=mx+b
M is slope
B is y intercept
Given the information in the problem plug in the parts you know.
Slope -2/3
Yint -2
y=-2/3x-2
