Answer:
for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different
Answer:
Step-by-step explanation:
Find the y-intercepts, this should be sufficient to match with the graphs.
A.
- x = 0 ⇒ y = 1
- x = 0 ⇒ y = - 1
This is the graph 2
<h3 />
B.
- x = 0 ⇒ y = - 2
- x = 0 ⇒ y = 2
This is the graph 3
<h3 />
C.
- x = 0 ⇒ y = - 2
- x = 0 ⇒ y = - 2
This is the graph 1
Answer:
irrational
Step-by-step explanation:
any number that is non terminating which means it never stop for example 3.972662516738394944... that would be irrational but the number 60 will be rational
Enrollment at X = 0 is at 20.
Enrollment at X = 8 is 120.
Find the difference between those values:
120 - 20 = 100
Divide that difference by the difference in the x values:
100 /8 = 12.5
The answer is D. 12.5
y = x² - 4x + 8
4x + y = 12
4x + y = 12
4x + (x² - 4x + 8) = 12
x² + 4x - 4x + 8 = 12
x² + 8 = 12
- 8 - 8
x² = 4
x = ±2
4x + y = 12
4(2) + y = 12
8 + y = 12
- 8 - 8
y = 4
4x + y = 12
4(-2) + y = 12
-8 + y = 12
+ 8 + 8
y = 20
(x, y) = (2, 4) and (-2, 20)
