PLEASE HELP ASAP

Lesechka [4]

Answer:

A. f and h

Step-by-step explanation:

For a linear function the First Differences of the y-values must be a constant. i.e. if we take the difference between any two consecutive y values or values of f(x) it should be the constant. For this rule to work, x values must change by the same number every time, which is true for all three given functions.

For function f:

The values of f(x) are: 5,8,11,14

We can see the difference in consecutive two values is a constant i.e. 3, so the First Difference is the same. Hence, function f is a linear function.

For function g:

The values of g(x) are: 8,4,16,32

We can see the difference among two consecutive values is not a constant. Since the first differences are not the same, this function is not a linear.

For function h:

The values of h(x) are: 28, 64, 100, 136

We can see the difference among two consecutive values is a constant i.e. 36. Therefore, function h is a linear function.

What is the measure of 21? 100° 90° 80° 85° 95%

Scorpion4ik [409]

Answer:

A quadrilateral's interior angles have a sum of 360°.

Given that we have 85°, 100°, and 90°(the right angle), and an unknown angle.

We can add these angles plus the unknown angle to equal a total of 360°.

85 + 100 + 90 + x(our unknown missing angle) = 360

simplify

275 + x = 360

Isolate x by subtract 275 from both sides;

-275 -275

x = 85, ∠1 = 85°

We can also double check:-

85 + 100 + 90 + <u>85</u> = 360

360 = 360 which is correct.

Tom is going to turn little Quacker into roast duck! He goes to the grocery store to get some salt and pepper seasoning to his d

MAVERICK [17]

Answer:

He can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper spent maximum.

Step-by-step explanation:

Given that:

The cost of salt = 50 cents / scoop =$ 0.5 / scoop

The cost of pepper =75 cents / scoop = $ 0.75 / scoop

Let he buys x scoops of salt and y scoops of pepper.

As he plans to bring home no more than 8 scoops of seasoning, so

$x+y\leq8\cdots(i)$

The total cost of x scoops of salt and y scoops of pepper = 0.5x+0.75y

As he wants to spend less than $5, so

$0.5x+0.75y$

Here, $x\geq 0, y \geq 0$ and x,y are counting numbers.

On plotting the graph of equations (ii) and (ii), the possible solution is the integral values in the shaded as shown in the figure.

The maximum possible integral values, for expances less than $5, are (x,y)=(3,4), (4,3).

Hence, he can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper to spent maximum.
