Answer:
The slope would be 1/2
Step-by-step explanation:
y= mx +b
m= slope
perpendicular lines have slopes that are multiplied in order to get -1
<em>these are important</em>
<em></em>
2x + y = 4
<u><em>subtract 2x</em></u>
y=-2x +4
your slope is -2
-2 * ? = -1
? = -1/-2
? = 1/2
Answer:
g(x) = (1/4x)^2
Step-by-step explanation:
Given f(x), we want to get g(x)
As we can see, the point (4,1) lies on the graph of g(x)
So the correct option will be the one where g(4) = 1
Let us take a look at the second option
g(x) = (1/4x)^2
Here,
g(4) = (1/4 * 4)^1 = 1^1 = 1
Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes
B) If A x B = {(-1, 1), (-1, 2), (2, 1), (2, 2), (3, 1), (3, 2)}. Find A x A and B x B.

hope this helps!
Step-by-step explanation:
A = {-1, 2, 3}
B = {1,2}
AxA = {(-1,-1) (-1,2) (-1,3) (2,-1) (2,2) (2,3) (3,-1) (3,2) (3,3)}
BxB = {(1,1) (1,2) (2,1) (2,2)}
Answer:
First we find the value of x,
x ≥ -4
Step-by-step explanation:
3x+7 ≥ -5
3x ≥ -5 -7
3x ≥ -12
x ≥ -4
Now to graph this inequality, consider number line.
numbers greater than and equal to -4 are -3,-2,-1,0 and so on.
Note that in solution -4 is included so in graphing we use dot (filled circle).
