Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.

Write the equation of a line with slope m= 1/2 half and including point (4, -1).
poizon [28]
Formula: y=mx+b
(4,-1) 
4 is x
-1 is y
m=1/2

-1=1/2(4)+b
1/2(4)=2

-1=2+b
-1-2=-3

-3=b

y=1/2x-3

Find f(2), f(1), f(0), and f(-1) for f(x) = 3x + 8.
cupoosta [38]

Answer:

Step-by-step explanation:

Solution

When, x=2

f(2)=3×2+8

=14

Again,

When, x=1

f(1)=3×1+8

=11

When, x=0

f(0)=3×0+8

=8

When, x=-1

f(-1)= 3×(-1)+8

=5
