Answer:
f(1) = 3
f(2) = 9
f(0) = 5
f(z) =2z + 5
Step-by-step explanation:
f(x) = 2x +5 let x = -1; 2, 0, z and simplify if you can.
f(-1) = 2(-1) +5 ; -2 +5
f(2) = 2(2) + 5; 4 + 5
f(0) = 2(0) + 5; 0 + 5
f(z) = 2z +5; 2z + 5
The length of BC would be 6ft

Answer:</h3>
<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>
Step-by-step explanation:
First add up the total amount of marbles in the bag.
14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.
Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).
7/31 ---> 0.22580645161 <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>
Lastly, round the decimal to the nearest hundredth.
0.22580645161 ---> <em>0.23</em>
<em>0.23</em> would be the odds of drawing a black marble.
Answer:
-9=-1/3-13 is it in slope intercept form, look up ones to put it in different forms
Step-by-step explanation:
Answer: y= 2x + 7
Step-by-step explanation:
Slope intercept form = y= mx + b
You are given slope (m=2) and a point (0,7) so
7 = 2(0) + b
7 = b;
So your equation is y= 2x + 7
