Factor out -x from the expression
Answer:
1
Step-by-step explanation:
Answer:
y = 3/7x
Step-by-step explanation:
Well slope-intercept form means this -----> y=mx+b
m = slope
b = y- intercept
In the question given they already telling us the slope (3/7) and the y intercept (0) so to put it into slope intercept form it will be ---> y= 3/7x
* If your y - intercept is zero you don't need to replace it with the b because its zero it means nothing (it has no value)
Hope this helps!!!
First let’s express the total number of marbles as such:
y(yellow marbles) + r(red marbles)=23; y+r=23
now let’s express the relation of yellow marbles to red marbles:
y=2r(2 times red marbles) - 4(4 less marbles); y=2r-4
since we figured out what y equals, we can plug into the first equation we created:
(2r-4)+r=23
now solve for r:
2r-4+r=23
combine like terms
3r-4=23
add 4 to both sides
3r=27
divide both side by 3
r=9
plug r back into first equation and solve for y:
y+9=23
subtract 9
y=14
there are 9 red marbles and 14 yellow marbles!
