Answer:
40+5x
Step-by-step explanation:
Eduardo put $40 in so the 40 is what he has already put in. Next you have $5 added in but it doesn’t say for how many months just that it’s each month so we put the x to represent out unknown so we can solve the equation.
Answer:
y = -8x + 4
Step-by-step explanation:
Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.
In this case, the slope is -8 and the y-int is 4 so we naturally plug those in

57,600
Step-by-step explanation:
720 * 80 = 57,600
Answer:
d = 5
Step-by-step explanation:
We want to know what d would be when x = -1, so we can start off by plugging in -1 for x to get the following equation: 
. On the left hand side, 2 negatives become a positive sign, so the -(-1) becomes a +1, and 8+1 would equal 9. On the right hand side, we just multiply 2 and -1 to get -2. So, the equation now looks like this: 
. We know that 
= 3, so we would get 3 = d-2. THen we would add 2 to both sides to get d = 5. Hope this helps!
Answer:
Slope of parallel line: -7/6
Slope of perpendicular line: 6/7
Step-by-step explanation:
7x + 6y = 5
6y = -7x + 5
y= -7/6x + 5/6
