Answer:
94
Step-by-step explanation:
the general formula for the nth term of this arithmetic sequence is
a(n) = 12 + 2(n-1).
The 42nd term would then be a(42) = 12+ 2(42 - 1) = 12 + 82 = 94
1. 1.5 and 3.5
2. both equations because they share these particular points
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
We ahve the slope m = 1/2 and the point (-2, 1). Substitute:
- point-slope form
Covert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>add 1 to both sides</em>
- slope-intercept form
Convert to the standard form (Ax + By = C):
<em>multiply both sides by 2</em>
<em>subtract x from both sides</em>
<em>change the signs</em>
- standard form
Convert to the general form (Ax+By+C=0):
<em>add 4 to both sides</em>
- general form
Answer:
No, no it is not.
Step-by-step explanation:
First step : Solve for y in − 2 x + y = − 7.
y = 2 x − 7
Second step : Substitute y = 2 x - 7 into 3 x + 2 y = 10.
7 x − 14 = 10
Solve for x in 7 x - 14 = 10.
x = 24 / 7
Substitute x = 24 / 7 into y = 2 x - 7.
- 1 / 7
That means your answer is.
x = 24 / 7
y = − 1 / 7
Angle X = 112 degrees, Angle Y = 123 degrees, Angle Z = 125.
