Answer:
10%
Step-by-step explanation:
To find this we make a fraction and multiply by 100%
4/40 *100% = 1/10 *100% = 10%

A = Anthony's weight
B = Anthony's brother's weight
A = 2B + 9 Plug in Anthony's weight
59 = 2B + 9 Subtract 9 from both sides
50 = 2B DIvide both sides by B
25 = B Switch the sides to make it easier to read
B = 25
Anthony's brother weighs 25 pounds.
Answer:
y= 3/5x+ 6.2
Step-by-step explanation:
the slope is change in y over change in x.
-4-(-1) divided by 3-8 will be -3/-5 = 3/5
For the y-intercept, plug in x and y values. I will use (3,8).
8= 3/5(3)+b
8= 9/5+b
(subtract 9/5 from both sides)= 6 and 1/5 or 6.2 as a decimal.
slope intercept form
y=mx+b
where m is the slope and b is the y intercept
if we change from point slope form
y-y1 = m(x-x1)
we distribute
y-y1 = mx -x*x1
then add y1 to each side
y = mx -x*x1+y1
remember x and y are variables and should stay in the equation
m,x1,y1 are numbers from the problem
you may have to calculate the slope (m) from the formula
m = (y2-y1)/(x2-x1) from two points on the line
