The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.
f(0) = 9(0)^2 - 7 - 8(0)
f(0) = -7
Therefore the “y” coordinate would be -7
The ordered pair would be
(0, -7)
To find B in terms of A (i hope this is what you want!) you can first multiply 3/7(B-25) by the reciprocal of 3/7, that being 7/3. You now have 7/3A=B-25, and through adding 25 on both sides, you have B=7/3A+25.
Hope this helps!
Answer is 8
If z=3 and z(3) is being subtracted from 11 then it is 11 minus 3,which is 8
Answer:
$40 and $72, see below :)
Step-by-step explanation:
One way we can do this is to add the total ratios and then divide that from 112.
10x + 18x = 28x = 112
28x = 112
x = 4
That means, for every ratio, you just have to multiply the amount by 4.
so for example, 10 is just 10 * 4 = 40
So, your answer would be you share the money into $40 and $72
