Answer:
431
Step-by-step explanation:
you take 7.75 divide it by 100 and then times it by 400
This is a maybe. Im not sure if this is right but its what I got.
The right expression is -1-2/7-(-3) which then gives you -3/10
Answer:
D
Step-by-step explanation:
take whole numbers to same side
subtract and add the x values
divide both side my the coeffecient of z
y=mx+b is the standard function for any straight line
y and x are constants, so they never change in the final form
m is the slope, which is given
b is the y intercept, which is not given
we have to plug in the values to find the solution, so plug in the (x,y) coordinates for their respective places in the equation
-8 = (-3/5)(-3) + b
-8 = 1.8 + b
-9.8 = b
now that we have b, we can just put the slope back in for m and get the answer
y= -3/5x -9.8
