If you would like to know the numbers, you can calculate this using the following steps:

a - b = 0.85 ... a = 0.85 + b
a + b = 1
___________________________
a + b = 1
(0.85 + b) + b = 1
0.85 + 2 * b = 1
2 * b = 1 - 0.85
2 * b = 0.15 /2
b = 0.15 / 2
b = 0.075

a = 0.85 + b = 0.85 + 0.075 = 0.925

The correct result would be: 0.075 and 0.925.

leva [86]

$f(0)=3(0)+1$

$f(0)=1$

$g(1)=\frac{4(1)+2}{3}$

$g(1)=\frac{4+2}{3}$

$g(1)=\frac{6}{3}$

$g(1)=2$

Hope this helps.

Marisol is preparing a care package to send to her brother. The package will include a board game that weighs 4 lb and several 1

So what we gotta do is isolate the variable by
writing it out like this
4 1/4 25 those are the numbers where those go are like this
4x - 1/4 < 25 then move on to the next line on here we write out
4x + 1/4 - 1/4 < 25 + 1/4 (The reason why i put + 1/4 is because you have to isolate the variable by doing addition as well And i always find it easier to convert the fractions to decimals then after you make that line you make the next one like this you have to add 1/4 to 4x then take it away (which is 4x) then put that to the side like this 4x ? ? then we need to find those two ?s by adding 25 and 1/4 (or o.25) which is 25.25 then we need to add that to the second answer 4x ? 25.25 when you have this you need to find out which one is bigger so it is 4x<25.25 (or 25 1/4) then we need to divide 4 and 25.25 to get 6.25 so
the answer is x < 6.25 so c is your awnser

AB is tangent to O. If AO = 32 and BC = 98, what is AB? my guess is 130? please help!

Juli2301 [7.4K]

CO = AO = 32 (Are rays.)
BO = BC + CO = 98 + 32 = 130
AB ⊥ BO
⇒ ΔAOB is a rectangular triangle.
We use Pitagora's theorem.

$\displaystyle\\
AB = \sqrt{BO^2 - AO^2} = \sqrt{130^2 -32^2}=\\\\
= \sqrt{16900 -1024}= \sqrt{15876}= \boxed{126 }$
