Answer:
a = -4/9
Step-by-step explanation:
(9a + 4) = 0
Subtract 4 from each side
9a + 4-4 = 0-4
9a = -4
Divide each side by 9
9a/9 = -4/9
a = -4/9
Answer:
I think √170
Step-by-step explanation:
The points are A: (-3,5) and (4,-6) so we plug this into the distance formula
√(x2-x1)^2+(y2-y1)^2
√(4-(-3))^2+(-6-5)^2
√(7)^2+(-11)^2=
√49+121= √170 or a really long decimal which starts out 13.038404810
If I got the points wrong I can redo the problem and get another answer but I did the problem on my own and used a calculator and got the same answer
<h3>Question:</h3>
2x-5y=-28 find the value of y when x equals -19
<h3>Answer:</h3>
Y = - 2
<h3>Step-by-step explanation:</h3>
First you plug in -19 where x is 2(-19)-5y = -28
Remove parentheses -2 · 19-5y= -28
Multiply -2 by 19 -38-5y= -28
Add 38 to both sides -5y = 10
Divide both sides by -5 [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex
you will get -2 which is the answer.
Hope this helped!
