The rent for an apartment is represented by R(a) = 2.00a + 50.00, where a is the area of the apartment in square feet. The rent

QveST [7]

Answer:

<em>The correct option is: D) S(a) = 2.00a + 100.00; shift 50 units up</em>

Step-by-step explanation:

The rent for an apartment is represented by $R(a) = 2.00a + 50.00$

Now, the rent increases by $50.00 when the apartment is furnished. So, the rent of a furnished apartment will be: $(2.00a+50.00+50.00) = (2.00a+100.00) dollar$

Thus the new function will be: $S(a)= 2.00a+100.00$

<u>As the output of the original function is increased by 50.00, so the graph of the original function will shift 50 units upward</u>.

How would you go about finding the solution to this system of three equations in three variables? Be specific. For example, you

kupik [55]

I:2x – y + z = 7
II:x + 2y – 5z = -1
III:x – y = 6

you can first use III and substitute x or y to eliminate it in I and II (in this case x):
III: x=6+y
-> substitute x in I and II:
I': 2*(6+y)-y+z=7
12+2y-y+z=7
y+z=-5

II':(6+y)+2y-5z=-1
3y+6-5z=-1
3y-5z=-7

then you can subtract II' from 3*I' to eliminate y:
3*I'=3y+3z=-15

3*I'-II':
3y+3z-(3y-5z)=-15-(-7)
8z=-8
z=-1

insert z in II' to calculate y:
3y-5z=-7
3y+5=-7
3y=-12
y=-4

insert y into III to calculate x:
x-(-4)=6
x+4=6
x=2

so the solution is
x=2
y=-4
z=-1

A box contains 500 marbles. The result of 20 marbles pulled at random from the box is given below.

Anni [7]

Answer:

100 black marbles

Step-by-step explanation:

The experimental probability of a black marble is

P(black) = 4/20 = 1/5

We expect that out of the 500 marbles in the box, 1/5 of them are black

1/5 (500) = 100

There should be 100 black marbles
