Nikitich [7]3 years ago
6 0

Answer:

(1,-8), (-6,-4), (3,7), (-6,1)

Step-by-step explanation:

In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:

The first choice (top left) has the x value, -6, repeating. It cannot be a function.

The second choice (top right) does not have an x value repeat. This makes it a function!

The third choice, (bottom left) does not have an x value repeat. This makes it a function!

The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!

Lesson 2-3
malfutka [58]

Answer:

18. g= -3

19. x= -1

20. n= 3

21. p= -1

22. d= -3

23. a= 5

Step-by-step explanation:

how to solve the variable (using 18 as an example)

step 1: simplify both sides of the equation.

20+g+g=14

(g+g)+(20)=14(combine like terms)

2g+20=14

2g+20=14

step 2: subtract 20 from both sides.

2g+20−20=14−20

2g=−6

step 3: divide both sides by 2.

2g/2 = -6/2

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast
IceJOKER [234]

Answer:

If 0.25 oz of yeast is used, then 50oz of flour is needed.

It would require 0.5 oz of yeast for 90 oz the flour.

Step-by-step explanation:

We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:

\frac{y}{f} = \frac{1}{200}

So if we use 0.25 oz of yeast:

y = 0.25\\\\y = (f)\frac{1}{200}\\\\0.25 = (f)\frac{1}{200}\\\\0.25 * 200 = f\\\\f = 50\ oz

if 0.25 oz of yeast is used, then 50oz of flour is needed.

If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:

\frac{y}{f} =\frac{1}{180}

So, if we use f = 90 0z of flour:

f = 90\ oz\\\\f = 180y\\\\90 = 180y\\\\y = \frac{90}{180}\\\\y = 0.5\ oz

It would require 0.5 oz of yeast.
