X-5
less than always means to subtract from
Answer:
They are all in slope and intercept form already
Step-by-step explanation:
Answer:
4/3x = 28/3 Multiply through by 3
You will get
4x = 28
x = 28/4
x = 7
Hope this helps.
X = -5 is a vertical line and therefore has an undefined slope.
This is a summation notation also called the sigma notation.
In this case it means starting with k=0 what's the sum of (1+k!) for all integer k until 4
So we just need to find the sum 1+0!+1+1!+1+2!+1+3!+1+4!=5+1+2+6+24=8+30=38
