B is just the y-intercept or where the line goes over the y axis so it would be 50
Answer:
f(-2) =3
Step-by-step explanation:
f(x) = 9+3x
Let x=-2
f(-2) = 9+3(-2)
= 9-6
= 3

<em>The Ordered pair of solution will be (x,y)=(2,3)</em>

<h3>Steps below⤵️</h3>
- Solve the second equation for y
- Substitute the given value of y into the first equation
- Solve the first equation for x
- Substitute the given value of x into the second equation
- Solve the equation for y
- The possible solution of the system is the ordered pair (x,y)
- And we are done solving!!~
I believe that Alex will need about 3 left because 100 cm= 1 meter. He already has 89 cm of pipe and that means he need 11cm to make it a meter. He needs 111cm left in order to have 2 meters which I beleive is 3 pipes I guess.
I hope this helps. :)
Triangles
ABC - AB=2.5, BC=1.5, CA=2 (5: 3: 4)
ADC - AC=2, CD= 1.2, DA= 1.6
BCD - BC=1.5, BD = 0.9, DB = 1.2
Area
ABC = 1/2 *AC * CB = 1/2 *2 * 1.5 = 1.5 m^2
ADC = 1/2 *AD * DC = 1/2 * 1.6 * 1.2 = 0.96 m^2
BCD = 1/2 *BD * DC = 1/2 * 0.9 * 1.2 = 0.54 m^2
