Y = x
when x < -1
not equal to (≤) so no solid circle.
plot points
x | y
-1, -1
-2, -2
-3, -3
Next one is...
y = -x
when x ≥ -1
solid circle for equal to
look at points
x | y
-1, 1
0, 0
1, -1
2, -2
As you can see it's the last graph in bottom right corner.
Answer: 7 years
Step-by-step explanation:
The Chubby bunny currently weighs 5 pounds but is increasing by 3 pounds per year. Assuming we wanted to find the weight in a given year, we can assume that given year is x. The expression would be:
= 5 + 3x
The fat cat weighs 19 pounds and gains by 1 pound a year.
Expression is:
= 19 + 1x
Equate the two equations together and find x:
5 + 3x = 19 + 1x
3x - 1x = 19 - 5
2x = 14
x = 14/2
x = 7 years
Answer:
arc ABC = 196°
arc DC = 360 - 196 - 70 = 94° (which looks out of proportion, but so does angle D)
Step-by-step explanation:
arc ABC = 2(∠D) = 2(98°) = 196°
Answer:
The graph increases 5 in the vertical direction for every 1 unit increase in the horizontal direction. It crosses the y axis at the point -3
Step-by-step explanation:
As we increase x by 1 (going from 1 to 2)
y goes from 2 to 7 or an increase of 5
As we increase x by 1 (going from 2 to 3)
y goes from 7 to 12 or an increase of 5
There for the slope is change in y/ change in x = 5/1
The y intercept is the value when x = 0 , which is -3
The equation is in the form y = mx+b
y = 5x-3
The graph increases 5 in the vertical direction for every 1 unit increase in the horizontal direction. It crosses the y axis at the point -3
