Answer:
Step-by-step explanation: Hey for the second one I got y = -3/4x -0.5 I'm not sure if its correct though sorry if not
ill try my best to explain my solution though
1. From the parallel equation (3x + 4y = 12) all we need to do is find the slope
So the easiest way to do so is to put the said equation in <u>y-intercept </u>form
y=mx +b
m= slope
b= y intercept
so 1. 3x + 4y = 12
=
4y = 12-3x
divide that by 4 to get only y
y=3-3/4x
-3/4 is our slope
y=-3/4x+b
than we have a point -2, -2
if we put -2 for y
-2=-3/4x+b
and then we put our -2 for x
-2 = -3/4 * -2 + b
=
-2 = -1.5 +b
b=-0.5
Answer : y=-3/4x-0.5
Answer:
-3
Step-by-step explanation:
Just put that trust me
By evaluating the linear function in x = 7 we conclude that:
<em>"The value of f(7) is 6.50, and it represents $6.50 remaining after playing 7 songs."</em>
<h3>
</h3><h3>
Which statement about f(7) is true?</h3>
Here we have the linear function f(x)= 10 - 0.5*x, it represents the amount of money remaining after x songs are played on the jukebox.
Then, that function evaluated in 7 is:
f(7) = 10 - 0.5*7 = 10 - 3.5 = 6.5
This means that after you play 7 songs, the amount of money remaining is $6.5
From this we can see that the correct option is:
<em>"The value of f(7) is 6.50, and it represents $6.50 remaining after playing 7 songs."</em>

Answer:
6*6=36 sq cm
Step-by-step explanation:
The base is a square therefore the area is length * width
Definition of square also means all sides are equal therefore it would be 6*6
