Which of the following options best describes the function graphed below?A graph shows a slanting straight line that starts at the origin and goes up.
Nonlinear increasing Nonlinear decreasing Linear increasing Linear decreasing I believe the answer is C. but I also think its D but I'm seriously stuck

Answers

Answer:

The graph of the function is:

                   Linear increasing.

Step-by-step explanation:

  • We are given a graph such that it is a slanting straight line.

This means that the relationship is linear.

  • Also the graph starts at origin and goes up.

This means that the graph of the function is continuously  increasing.

Hence, the option that best describes the function graphed is:

Linear increasing.
It is going to be : Linear increasing (C)

One group of people purchased 10 hot dogs and 5 soft drinks for $35. Another group purchased 7 hot dogs and 4 soft drinks for $25.25. What is the cost of a single hot dog? A single soft drink?

Answers

10 H + 5 D = $35         times all by 4      40 H + 20 D =  $140.00
  7 H + 4 D = $25.25  times all by  5    -  35 H - 20 D    = -126.25 and subtract
 Subtract                                                  5 H          =  $13.75
 Divide by 5 to find price of one hot dog          H          =  $2.75

10 ($2.75) + 5 D = $35  input cost of one hot dog into first equation
   $27.50  + 5 D  =   $35.00
- $27.50              = -$27.50
                   5 D  = $ 7.50 divide by 5 so one drink is $1.50 then go back and check

Please help me! I’m so confused!! I will give BRAINLIEST :) A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.

If angle BAC = 22 degrees the angle ABC = ?

Answers

Answer:

136 degrees

Step-by-step explanation:

if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136

Answer:

Angle ABC is equal to 136 degrees.

Step-by-step explanation:

Since sides AB and BC are congruent (meaning they are equal to each other),  they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.

Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.

136 + 22 + 22 = 180, so this works!

I hope this helps!
