Answer:
So the mid-point is (10.5,2)
Step-by-step explanation:
By using mid-point formula
M(x,y)=(x1+x2)/2,(y1+2)/2
Putting the values of the coordinates
M(x,y)=(6+15)/2,(-4+8)/2
M(x,y)=21/2,4/2
M(x,y)=10.5,2
So the mi-point is (10.5,3)
I hope this will help you :)
The correct answer is the Last choice b=3-2a
Ax² + bx + c = 0
2x² + x - 3 = 0
2x² + x + (-3) = 0
x = <u>-b +/- √b² - 4ac</u>
2a
x = <u>1 + /- √1² - 4(2)(-3)</u>
2(2)
x = <u>1 + /- √1 +24</u>
4
x = <u>1 +/- √25
</u> 4<u>
</u>x = <u>1 + /- 5
</u> 4<u>
</u>x = <u>1 + 5</u> x = <u>1 - 5
</u> 4 <u> </u> 4<u>
</u>x = <u>6</u> x = <u>-4</u>
4 4
x = <u>3</u> x = -1
2
x = 1 1/2
x = 1 1/2 x = -1
There are many ways you can say it,
one of them would be:
8 added to 5 multiplied by x
2.19. say the fraction out loud, “two nineteenths” and it really helps to remind you how to convert it to a decimal.
