Answer:
y=-2/4x + (-4.5)
Step-by-step explanation:
so first we look for the slope which is rise/run.
start with the lower point and count up two.
the count to the left and you have -2/4, thats your slope.
then you chose one point, like (1,-5)
so either using point slope form y-y1=m(x-x1) or standard form y+mx+b
im going to use standard form
plug in your points like so:
y= -2/4x +b
-5= -2/4(1) +b
-5 = -1/2 + b
-5+ 1/2 = b
-4 1/2 =b
so y should equal
y=-2/4x + (-4.5)
im not sure but i hope this helps a bit
Answer:
- 2 1/4 pounds of blueberries
Step-by-step explanation:
Blueberries - b, raspberries - x
<u>Equations as per question:</u>
<u>Eliminate b and solve for x:</u>
- 1/5x = x - 1 4/5
- x - 1/5x = 1 4/5
- 4/5x = 9/5
- x = 9/5 : 4/5
- x = 9/5 *5/4
- x = 9/4
- x = 2 1/4
Answer:
$2475 or $1875
Step-by-step explanation:
Assuming the question meant to say $25 less than the original price, it would be $2475 because $2500-$25= $2475
However, if the question meant to say that Sam bought the iron for 25% less than the original price, it would be $1875 because 2500*0.25= $625
$2500-$625= $1875
Yes...because every x value corresponds to exactly one y value
a function will not have any repeating x values...it can have repeating y values, just not the x ones. So if all the x values are different, then it is a function
