Answer:
80%
Step-by-step explanation: Because if 20% of 250 equal 50 then 200 is 80% because adding 4 50 is 200.
51/85
Step by step explanation:
The sine of an angle: the length of the opposite side/the length of the hypotenuse
In this case it’s Sin A so it would be
The side opposite to A is 51
Length of hypotenuse is 81
Therefore 51/81
So y=mx+b form
m=slope=rise over run
b=y intercepe or where it crosses the y axis
so one way is to input values for x and get vales for y exg
if x=1 then y=-2
if x=2 then y=1
if x=0 then y=-5 so some points are
(x,y)
(1,2)
(2,1)
(0,-5)
(3,4)
then plot those points
Answer:
x=4
Step-by-step explanation:
4x+7=23
4x=23-7
4x=16
x=16÷4
x=4
