Convert decimal to fraction
a^2+(21/10)^2=2.9
Use exponent rules
a^2+441/100=2.9
Move constant to the right
a^2=2.9-441/100
Calculate
a^2=-151/100
This equation has no solution.

Yes,this is a doozy.

                 <u>-3 (y - 5)  =  15</u>

Eliminate the parentheses on the left side:

                 -3(y) -3(-5)  =  15

                 -3y  + 15  =  15

Subtract 15 from each side: 

                 -3y  =  0

Divide each side by -3 :

                  <em>  y  =  0</em>

Help me with this problem thank youuup.
UkoKoshka [18]

Step-by-step explanation:

it is a linear function, if the change in y is constant in relation to the changes of x.

in other words, if the slope y change/x change is the same for every point.

when we look at the table, we see x changes constantly by +2.

and y changes constantly by -6.

so, the change rate/slope is constantly -6/2 = -3.

and therefore it is a linear function.

the equation looks like (the slope is always the factor of x)

y = -3x + b

b we get by using one of the x,y pairs like 1,4

4 = -3×1 + b = -3 + b

b = 7

so, the full equation is

y = -3x + 7

What is the solution to the inequality below?
dimaraw [331]
  • 12 + x ≥ 3 (x - 6)
  • or, 12 + x ≥ 3x - 18
  • or, 12 + 18 ≥ 3x - x
  • or, 30 ≥ 2x
  • or, 30/2 ≥ x
  • or, 15 ≥ x
  • or, x ≤ 15

<u>Answer</u><u>:</u>

<em><u>x </u></em><em><u>≤</u></em><em><u> </u></em><em><u>1</u></em><em><u>5</u></em>

Hope you could get an idea from here.
