1<br> 6 points<br> Solve for x:<br> 3x - 2 = x + 8<br> (Engin+bon.
gizmo_the_mogwai [7]

Answer:

x = 5

Step-by-step explanation:

3x - 2 = x + 8

Subtract x from each side

3x-x - 2 = x-x + 8

2x -2 = 8

Add 2 to each side

2x-2+2 = 8+2

2x = 10

Divide each side by 2

2x/2 =10/2

x = 5

Are the point (-1, 1) and (3, 1/5) solutions to the equation 3x-5y=8
Sati [7]
The (3, 1/5) would be a solution while the (-1,1) wouldn’t because when you write this equation in the slope intercept form which is y = 3/5x - 8/5

1/5 = 3/5 (3) - 8/5

would end up with 1/5 = 1/5 which is write

While,

1 = 3/5 (-1) - 8/5

Would end up with
1 = 11/5 which is wrong

Consider a t distribution with 7 degrees of freedom. Compute P(-1.29 &lt; t &lt; 1.29). Round your answer to at least three deci
marusya05 [52]

Answer:

Step-by-step explanation:

Given that there is a t distribution with 7 degrees of freedom.

P(-1.29 < t < 1.29)=1-0.2380

=0.7620

b) Now there is a different t distribution with 18 df.

When P(t\leq c)=0.05

c=-1.733

y = \frac{3}{x^{2} - 4} + 1

Domain: x² - 4 ≠ 0
                 + 4 + 4
                    x² ≠ 4
                 √x² ≠ √4
                    x ≠ ±2
           x ≠ -2 and x ≠ 2
     (-∞, -2) ∨ (-2, 2) ∨ (2, ∞)

Range: y ≠ 1
