Step-by-step explanation:

<u>Step 1: Define</u>

h(x) = -5x + 3

h(5) is x = 5

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function]:                                                                                h(5) = -5(5) + 3
  2. Multiply:                                                                                                             h(5) = -25 + 3
  3. Add:                                                                                                                   h(5) = -22

You can spend at most $21 on fruit. Blueberries cost $4 per pound, and strawberries cost $3 per pound. You need at least 3 pound
Juliette [100K]

Answer:

<h2>a. The system of linear inequalities is x + y \geq 3 and 4x + 3y \leq 21.</h2><h2>b. The solution is given in the figure.</h2><h2>c. The given scenario can happen.</h2>

Step-by-step explanation:

Let, I will buy x pounds Blueberries and y pounds Strawberries.

I need to collect at least 3 pounds of fruits.

Hence, x + y \geq 3.

It also given that I can not spend more than $21, that is 4x + 3y \leq 21.

If I will buy 4 pound Blueberries  and 1 pound Strawberry, then x = 4 and y = 1.

Now, 4 + 1 = 5 > 3. First inequality is satisfied.

4x + 3y = 4\times4 + 3\times1 = 16 + 3 = 19 \leq 21, Second inequality is also satisfied.

Which relation does not represent a function? A. {(3, 0)}, {(0, 3)}. B. {(6, -2), (5, -2)}. C. {(3, 4), (3, 5)} D. {(5, 5), (-5,
Fittoniya [83]
A function will not have repeating x values...all the x values will be different. But u don't want a function...so u want repeating x values.
That leaves C...because u have repeating x values (3 is ur repeating x value)...so C is not a function

Which is an equation of the line that passes through the points (5 15) and (10 20)?
faust18 [17]
The generic equation of the line is:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)
 Substituting values:
 m = (20-15) / (10-5)
 m = (5) / (5)
 m = 1
 We choose an ordered pair:
 (xo, yo) = (5, 15)
 Substituting values:
 y-15 = 1 (x-5)
 y = x - 5 + 15
 y = x + 10
 Answer:
 
An equation of the line that passes through the points (5 15) and (10 20) is:
 
y = x + 10

Please look at the attachment and help me with my question! (╥︣﹏᷅╥)
Dafna1 [17]

we conclude that the store where you can get more sausages is in Peter the Butcher.

<h3>Which shop is the best option?</h3>

You have £10.

Peter the Butcher sells 6 sausages for £2.30

The number of packages that you can buy is:

£10/£2.30 = 4.3

Rounding down to the next whole number, we conclude that here you can buy 4 packages, then:

4*6 = 24 sausages

4*£2.30 = £9.20

So here you can buy 24 sausages for £9.20

In Paul the butcher, you can buy 10 sausages for £3.50

Notice that here you can only buy 2 packages (because the cost of 3 packs would be  £10.50, which is more than the amount you can spend).

Then here you only can get 20 sausages.

Then, we conclude that the store where you can get more sausages is in Peter the Butcher.
