Please answer this with the steps included please<br> y-10 = -5/4x + 30/4<br> for middle school
Phantasy [73]
<span>y-10 = -5/4x + 30/4 represents a linear function; we know that because both x and y have the power 1.

We could put this equation into one of several forms.

Suppose we wanted to put it into slope-intercept form.  Then </span><span>y-10 = -5/4x + 30/4 becomes y = 10 + 30/4 - (5/4)x, or y = 35/2 - (5/4)x.  Thus, this line has the slope -5/4 and the y-intercept (0, 35/2).

If this isn't quite what you wanted, then please share the instructions.

Answer:

  1a: x+3 = 5

  1c: 6 = 2z

  2b: x = 2

  2d: 3 = z

  3: the solutions make the hangars balance

Step-by-step explanation:

1. We can write the equations by listing the contents of the hangar and using an equal sign to show the balance between left side and right side. It can work well to put left side contents of the hangar on the left side of the equal sign.

  A: x + 3 = 5

  C: 1 + 1 + 1 + 1 + 1 + 1 = z + z  simplifies to  6 = 2z

__

2. B: We can subtract 3 from both sides of the hangar (and equation) to find the value of x.

  (x +3) -3 = 5 -3

  x = 2 . . . . . hangar balances with 2 on the right

D: We can divide both sides of the hangar by 2, splitting the content into two equal parts. Then one of those parts can be removed from each side.

  2(3) = 2(z)

  3 = z . . . . . . hangar balances with 3 on the left

__

3. The found values will keep the hangar in balance when they are substituted for the corresponding variables.

  A: 2 + 3 = 5

  C: 1 + 1 + 1 + 1 + 1 + 1 = 3 + 3

Given f(x) = 3x^2+x+1 <br> g(x)+-2x-1<br> find (f+g)(-2)
yawa3891 [41]

Answer:

38

Step-by-step:

f(-2)=3(-2)^2+(-2)+1                  g(-2)=-2(-2)-1

f(-2)=-6^2+(-2)+1                      g(-2)=4-1

f(-2)=36+(-2)+1                         g(-2)=3

f(-2)=34+1

f(-2)=35

f+g ------- 35+3 ------- 38

Artemon [7]

Answer:

Step-by-step explanation:

As she watches 90 minutes of tv pre day and she watched 10 minutes before school

So minutes left 90-10=80

And 1 episodes contains 20 minutes

So she can watch tv episodes

= 80÷20

=4 (ans)

Note:It is the answer as far as I know. If you have any doubt you can go with others
