Do u have a pic of the problem
Answer:
f(5)=12
Step-by-step explanation:
Replace all x by 5
f(5)=3(5)-2
multiply 3 and 5 together
f(5)=15-2
Simplify:
f(5)=13
Hope this helps!
Answer:
A. y=x-3
B.y=x-3
Step-by-step explanation:
Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=x-3
10(white socks)+6(black socks)+8(blue socks)= 24(total socks)
now you take the # of white socks over the total number of socks
10/24 or 5/12
I supposed you mean add the equation h + 3 to 6h + 1?
6h + 1 + h + 3 = 7h + 4
But if you mean subtract the equation h + 3 from 6h + 1
6h + 1 - (h + 3) = 6h + 1 - h - 3 = 5h - 2
