5. Which of the following inequalities could be modeled by the graph below?

user100 [1]

Answer:

The answer is C, x/-2 > -1

Step-by-step explanation:

The inequality that the graph models is x < 2.

If you want the right side to be -1, then you would have to multiply both sides with -2. When multiplying with a negative, the sign of values on both sides are switched, resulting in x/-2 > -1.

Find an equation of a line with the x- and y-intercepts below. Use exact fractions when necessary.

tamaranim1 [39]

Answer:

$y=\frac{5}{7}x-5$

Step-by-step explanation:

All lines in the plane are of the form

y = mx+b

The intersection with the Y-axis is obtained by replacing x with 0

The intersection with the X-axis is obtained by replacing y with 0

If we want that the Y-intercept = -5, then

-5 = m(0)+b

So b = -5

Our temporal equation is then

y = mx-5

If we want that the X-intercept = 7, then

0 = m(7)-5

7m = 5

m = 5/7

So our final equation is

$y=\frac{5}{7}x-5$

Attached is the graph of the line

Answer:

fdg=gce ( vertically opposite angle)

or,fdg=23

Step-by-step explanation:

or, x+fdg = 90 (supplementary angle)

or,x+23=90

or, x =90-23

or,x=67

so, the value of x is 23
