Answer:
y = 14/5x + 2
Step-by-step explanation:
is seems as though the y-intercept would be 2 and the slope is 2.8 which is
2 4/5 or 14/5
therefore, equation would be y = 14/5x + 2
Using this equation, f(3) = 23.
In order to find the value of f(3), we need to take the f(x) equation and put 3 everywhere we see x. Then we follow the order of operations to solve. So, let's start with the original.
f(x) = 2x^2 + 5sqrt(x - 2)
Now place 3 in for each x.
f(3) = 2(3)^2 + 5sqrt(3 - 2)
Now square the 3.
f(3) = 2(9) + 5 sqrt(3 - 2)
Do the subtraction inside of the parenthesis.
f(3) = 2(9) + 5sqrt(1)
Take the square root
f(3) = 2(9) + 5(1)
Multiply.
f(3) = 18 + 5
And add.
f(3) = 23

B. 4
*Steps*
83-15=68
68/17=4
2(box 1):
how to solve: 25m+200=?
m(minutes)=10
25(10)+200=450
*Give me a little to work out the other three please!*
12/30 = 18/45, so first you're going to cross multiply and you'll get (30)(18) = (12)(45). Then you can see that 540 = 540 same number so they're proportional...
BTW THIS WAY IS A LOT EASIER.
12/30 = 2/5
18/45 = 2/5
So yes, in summary, they're proportional to each other. Hope this helps, have a BLESSED and wonderful day! :-)
Yes there is because u can multiply it by different numbers except for 1 and 0
