In total he ran 19 miles based off of how the question looks. It looks like I needed to add each number up.
Answer:
Slope = 5.
y-int = (0, -2).
Step-by-step explanation:
y = 5x - 2
The slope intercept form is
y = mx + b where m = the slope and b = the y-intercept.
So here, the slope = 5 and the y-intercept is where y = -2. That is the point (0, -2).
Answer:
(2,-3)
Step-by-step explanation:
I thought you'd actually have to calculate it but I guess they just wanted to give you guys a graph lol
Answer:
There are 26 purple marbles in the bag.
Step-by-step explanation:
Firstly, you have to make an expression in terms of x where x represent red marbles. Given that the question says purple marbles is 2 more than 3 times the number of red marbles. So the expression is :
Let red marbles = x,


Next, given that the total marbles in the bag is 34 so you have to add both marbles together and solve the value of x :




Lastly, you have to substitute the value of x into the expression of purple marbles :
Let x = 8,
