Answer:
a = 1 and b = 14 or a = 14 and b = 1
Step-by-step explanation:
This means that ab = 14 and a + b = 15. Simple guess and check reveals (1, 14) or (14, 1).
Answer:
y=2x-46
Step-by-step explanation:
Select any two coordinate points. I'm picking (1,-44) and (2, -42).
x1 and y1 are the first coordinates. x2 and y2 are the second coordinates. The formula for finding the slope of a linear fuction is (y2-y1)/(x2-x1). Substiute the numbers into this formula:
-42-(-44)/2-1
=-42+44/1
=2
This is the slope. In y=mx+b, plug in your newly found slope. Next, to find the y-intercept, plug any pair of coordinate points into your incomplete formula y=2x+b. I'm going to use (1,-44) again.
-44=2(1)+b
-44=2+b
b=-46
Now, plug this into your formula, and you'll get y=2x-46.
Answer:
D) y = -3
Step-by-step explanation:
3y² +2(y – 5) > 8
3y² + 2y - 10 - 8 > 0
3y² + 2y - 18 > 0
y = -3
3(-3)² + 2(-3) - 18
27 - 6 - 18
3 > 0
X = 2 y = 1
y = 5 x= 4
x = -2 y = -7
y= 0 x= -3
