Answer:
Slope intercept formula= y=mx+b
Step-by-step explanation:
m is the slope of the line and b is the y intercept
in this case b=5
y=mx+5
now, to get to the next point, we find our slope. rise/run
we rise 4 and run 1
y+4/1x+b
Formula for area of rectangle:
A=L x w
Here A=85 square ft
Length, L=w+12
Put values in formula.
85=(w+12)w
85=w^2+12w
Subtract 85 from both sides
w^2+12w-85=0
Factorise the equation.
(w-5)(w+17)=0
w=5 and w=-17
Ignore the negative value of width.
Width, w= 5 ft and Length, L=12+5=17 ft
Answer: Width=5 ft and Length=17 ft
There are four cups in a quart of water.
Answer:
36
Step-by-step explanation:
Let's call the # of boys and girls 5x and 3x respectively. We can write:
5x = 3x + 24
2x = 24
x = 12 so the # of girls = 12 * 3 = 36
A(n)=3+2(n-1)
Hope this helps
