write the equation of a line parallel to y = 2x + 2 that passes through the point (-1, -7). Please show your work:)

Answer:

The equation of the line would be y = 2x - 5

Step-by-step explanation:

To find a line parallel to this one, note that parallel lines have the same slope. Since the first line has a slope of 2, then we know the second does as well.

Now we use that slope and the point in point-slope form and solve for y.

y - y1 = m(x - x1)

y + 7 = 2(x + 1)

y + 7 = 2x + 2

y = 2x - 5

-BARSIC- [3]

Answer:

6 $\frac{1}{2}$

Step-by-step explanation:

you are adding 3 1/4 to 3 1/4 which is 6 2/4 or 6 1/2

or you can multiply 13/4 by 2 to get 26/4 or 13/2 which, again, is 6 1/2

Answer:

41 square miles

Step-by-step explanation:

There are several ways you can compute the area of this polygon. We have elected to divide it into a rectangle and a triangle.

The rectangle has dimensions 8 × 4.5, so area ...

A = LW = 8 × 4.5 = 36 . . . . . square miles

The triangle has height 2.5 and base 4, so area ...

A = (1/2)bh = (1/2)(4)(2.5) = 5 . . . . . square miles

Then the total area is the sum of these:

36 + 5 = 41 . . . . . square miles

Answer:

The confidence level interval is $0.016 \le C \le 0.404$

Step-by-step explanation:

The sample size is $n = 20$

The number planning to increase workforce is $x = 3$

The confidence level is $c = 98$ %

The value of proportion for a plus 4 method is

$p = \frac{x+2}{n+4}$

substituting values

$p = \frac{3+2}{20+4}$

$p =0.21$

The z-critical value at confidence level of 98% is

$z_{c}=z_{0.98} = 2.33$

This values is obtained from the standard normal table

The confidence level interval can be mathematically represented as

$C =p \ \pm z_{c} * \sqrt{\frac{p(1-p)}{n+4} }$

substituting values

$C = 0.21 \pm 2.33 * \sqrt{\frac{0.21(1- 0.21)}{20 +4} }$

$C = 0.21 \pm 0.194$

=> $0.016 \le C \le 0.404$
