Simple...
you have: 15x+2=17
Isolate the variable (x)-->>>>
15x+2=17
-2 -2
15x=15
x=1
To check it-->>>
15(1)+2=17
17=17
Thus, your answer.

Answer:
CI = 29.8 ± 3.53
Critical value is z = 2.58
Step-by-step explanation:
First of all let's find margin of error. It is given by the formula;
ME = zσ/√n
We are given;
Standard deviation; σ = 3.62
Sample size; n = 7
Mean; x¯ = 29.8
Now, z-value for 99% Confidence level is 2.58
Thus;
ME = (2.58 × 3.62)/√7
ME = 3.53
CI is written as;
CI = x¯ ± ME
CI = 29.8 ± 3.53
Critical value is z = 2.58

Step-by-step explanation:
The vector equation of the line is:
The parametric equations of the line are:
and
Formula of the area of a triangle:
A = hbb/2
Plug in the numbers.
26 · 26/2
= 338
Therefore, the area of the triangle is 338
