The zeros of <span>y = 3x^2+3x  means to solve for the values of x when y = 0

</span> <span>y = 3x²+ 3x =0
</span>
<span>y = 3x²+3x  = 0
</span>
<span>3x²+3x  = 0                  Factorize

3x(x + 1) = 0

3x = 0,  or (x + 1) = 0

From 3x = 0,  x = 0/3 =0

From (x + 1) = 0,  x = 0 -1 = -1.

Therefore the zeros are 0 and -1.

John, and bill shared $900 in the ratio 7:3 respectively. how much money did each person get?
S_A_V [24]

John get money $630 and bill get money $270.

Given that John and bill shared $900 in the ratio 7:3 respectively.

The ratio is defined as the comparison of two quantities of equal units, indicating the quantity of one quantity contained in the other quantity.

The total ratio is 7+3=10

For john:

John has money seven out of 10 for the $900, we get

J=900×(7/10)

J=90×7

J=630

For bill:

Bill is three out of ten for $900, we get

B=900×(3/10)

B=90×3

B=270

Hence, john get money $630 and bill get $270 when they both shared $900 in the ratio 7:3 respectively.
