Answer:

All real numbers

Step-by-step explanation:

f[x]= -8x stems from the ramp function y = x, whose domain is "all real numbers" and whose range is "all real numbers."

Thus, the range of f[x] = -8x is "all real numbers."

2. A line passes through points (-1,-2) and (1,4). What is the equation of the line? TI​
Simora [160]
Slope = "rise over run" the difference in y values divided by the difference in x values
= 6/-3 = -2 = m. It's negative because as x increases, y decreases

plug that into the point slope formula, with either point. generally use the most simple point
y-h= m(x-k) where m= -2 and (k,h) = (2,-2)

y+2 = -2(x-2)

simply if you want

Y = -2x +4 -2 = -2x +2

or

2x +y = 2

What is the range of the given function?
Fed [463]

9514 1404 393

Answer:

  (b)  {yly = -9, -3, 0, 5, 7}

Step-by-step explanation:

The range is the set of y-values in the ordered pairs. It is usually convenient to list a set in alphanumeric order.

The second values of the ordered pairs are 0, -3, -9, 5, 7. So, the range is ...

  y ∈ {-9, -3, 0, 5, 7} . . . . . matches the second choice

Question 3 of 10<br> Which graph shows the solution to this system of inequalities?<br> y&gt;2x-3
belka [17]

Step-by-step explanation:

the graph should start on (-3) on the y-axis from there go up 2 and over one and that should be your next point on the graph.

you didn't show the graphs but to figure out if the color goes on the top or bottom... do

point (0,0)

plug into equation y<2x-3

(0)<2(0)-3

0<-3 (false)

wouldn't include the point (0,0)

hope this helps

A bag contains three different shaped pieces of card
algol13

Answer:

2:3:5

Step-by-step explanation:

Here, we are going to be using direct numbers from the ratio

Circles to triangles is; 2:3

So for 200 circles, there are 300 triangles

Triangles to rectangles ; 2:5

300 triangles, there are 500 rectangles

Circles to triangles to rectangles is thus;

200: 300:500

= 2:3:5
