There are 16 ounces in 1 pound and 8 ounces in 0.5 pounds. 16(2)= 42+ 8= 38 ounces
Slope is 2 and y-intercept is -3/4
Okay so first plug this in
8-5
——
5-6
3/-1
-3
Slope= -3
y=-3x+b
Next, plug in one of the points to find b.
5=-3(6)+b
5=-18+b
+18 +18
—————
23=b
y=-3x+23
Hope this helps!!
Answer:
(2,2)
Step-by-step explanation:
Given equations
x-3y=-4-------------------------------(1)
y=-3x+8.------------------------------(2)
Substitute 2 in 1. This means use the value of y in equation 1, to replace y
x-3(-3x+8)=-4------------------open brackets
x+9x-24=-4---------------------collect like terms
10x=-4+24
10x=20---------------------------divide by 10 both sides to get value of x
10x/10=20/10=2
x=2------------------------------use value of x in equation (2) to get value of y
y=-3x+8
y=-3(2)+8
y=-6+8=2
solutions
x=2, y=2
