Answer:
Option B is correct
Step-by-step explanation:
Given data
We are given the expression
-4x + 2y > 12
We want to substitute y=4 into the expression
-4x + 2(4) > 12
-4x + 8 > 12
-4x> 12-8
-4x> 4
divide both sides by -4
x> 4/-4
x>-1
Hence option B is correct
Answer:
The 2nd graph
Step-by-step explanation:
The y-intercept of the second graph has a y intercept of 6 and a slope of 3.
(2)^4-2(2)^3-6(2)^2+5
16-64-144+5
-187
Answer:
each of his parents are 42 years old.
Step-by-step explanation:
The slope-intercept form is:
y = mx + b
where m = slope, and b = y-intercept.
You need a slope of 1, so m = 1.
You need a y-intercept of -1, so b = -1.
Replace m with 1 and b with -1 in the slope intercept form to get
y = 1x + (-1)
which simplifies to
y = x - 1
