For the equation y - x < 0,y < xThe shaded portion will be under the dashed line joining points (-2, -2) and (3, 3).
for the equation x - 1 > 0,x > 1The shaded portion will be to the right of the dashed line joining points (1, 5) and (1, -3).
The portion affected by the two shadings will be the portion common to the right of the dashed line joining points (1, 5) and (1, -3) and under the dashed line joining points (-2, -2) and (3, 3).Therefore the correct answer is option c.

Answer:

y>x+3 and y\leq x+2

Step-by-step explanation:

Step 1

Find the equation of the inequality A (dashed line)

we know that

The solution of the inequality A is the shaded area above the dashed line

The equation of the dashed line is y=x+3

therefore

The equation of the inequality A is y>x+3

Step 2

Find the equation of the inequality B (solid line)

we know that

The solution of the inequality B is the shaded area below the solid line

The equation of the solid line is y=x+2

therefore

The equation of the inequality B is y\leq x+2

hence

The system of inequalities is equal to

y>x+3 and y\leq x+2

Which linear function represents the line given by the point-slope equation y + 7 = –2/3(x + 6)?a. f(x) = –2/3x – 11b. f(x) = –2
Pavel [41]

Answer:

option C

y=\frac{-2}{3}x-11

Step-by-step explanation:

The point slope equation of a line is given by

y-y_1=m(x-x_1)

Where m is the slope and (x1,y1) is the point on the point

y + 7 =\frac{-2}{3}(x + 6)

We need to write the equation in y=mx+b form

multiply -2/3 inside the parenthesis

y + 7 =\frac{-2}{3}x-4

Subtract 7 from both sides

y=\frac{-2}{3}x-11

Neko [114]

Answer:

The correct answer is option (C)-0.245 = 2.160(0.205)

Step-by-step explanation:

Solution

Given that:

The slope = - 0.245

The size sample = n = 15

The standard error = 0.205

The confidence level = 95

The Significance level= α = (100- 95)% = 0.05

Now,

The freedom of degree = n-2 = 15 -2= 13

Thus,

the critical value = t* = 2.16

By applying Excel = [TINV (0.05, 13)]

The Margin of error is = t* (standard error)

=2.16 *0.205

= 0.4428
