● To do this, you need to multiply 6.75 by 21 to find out how many meters are in all. 6.75×21 is 141.75
● Next you multiply 141.75 by 2 to see how much it costs which is 283.5
● Since we're dealing with money, it would have two place values so we add a zero and we get $283.50
6r 3r
J_______K_______L
--------------27------------
JK + KL = JL
6r + 3r = 27
9r = 27
r = 27/9
r = 3 <=====
3 3/4 + 1 1/4 + 2 2/4
3/4 + 1/4 + 2/4 = 1 1/2
3 + 1 + 2 + 1 1/2 = 7 1/2 cups total
To find y you need to insert x into the equation. The equation is y=2x+2, so insert the x on the table to find the y.
y=2(-4)+2=-6
y=2(-2)+2=-2
y=2(0)+2=2
y=2(1)+2=4
y=2(3)+2=8
These follow the equation's rule so it is correct.
Two plot the values of x and y you need to put it in (x,y) then plot it. Then you can check it by using the equation, y=mx+b, the b is the y intercept, so check to see if it starts there, and then check and see if it followings the slope
(-4, -6), (-2, -2), (0, 2), (1, 4), (3, 8)
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
