Answer:
3i + 63j
Step-by-step explanation:
Step 1: Replace the variables with the given statements
5(3i+9j) - 3(4i-6j)
Step 2: Distribute
15i + 45j -12i + 18j
Step 3: Combine like terms
3i + 63j
Answer: 2
Step-by-step explanation:
The given equation is in slope-intercept form. It is y=mx+b. In this equation, m stands for slope and b stands for y-intercept. Looking back at the equation, we see that in place of m is 2. That tells us that the slope is 2.
We add 25/8 yards and 1 3/4 yards together.
First we convert 1 3/4 to an imp. fraction 7/4.
In order to add fractions, they must have the same common denominator. So we multiply both sides of the fraction 7/4 by 2 to get 14/8. Now we can add 25/8 yards and 14/8 yards together to get 39/8 yards.
I don’t know for sure if this is right but I got f(-3)=1.
f(-3)= -x - 2
f(-3)= -(-3) - 2
The 2 negatives cancel each other out and make a positive.
f(-3)= 3-2
f(-3)=1
