Answer:
(1,4)
Step-by-step explanation:
The two lines intersect at 1,4 when you graph them
The first equation is already in slope intercept from, so you know the y-int. is 7 and the slope is 3. However, the second equation must be put in slope int. form.
5x+2y=3
move the y to the other side
5x=3-2y
move the 3 to the other side, so the y variable is by itself
5x-3=-2y
divide by -2 to the equation is equal to y
(-5x/2)+(3/2)=y
you now know the y int. of the second equation is 3/2 and the slope is -5/2
know that you know the slop int. formulas for both equations you can graph them
Answer: D and E
the answers is between 1 and 2 so A is out
the dot is a little more than halfway so B and C are out
D and E are left :)
Answer:
1) (f + g) (5) = 18, 2) (f + g) (1/2) = - 13/4, 3) (f - g) (-1) = 14, 4) (f * g) (7) = 456, 5) (f/g) (- 2) = - 3/4, 6) (g ○ f)(x) = 6 x - 23, (f ○ g)(x) = 6 x - 6, 7)

Answer:
1//12.
Step-by-step explanation:
The possible ways to get a sum of 4 are (1, 3), (3, 1), (2, 2) .
There are a total of 6 * 6 = 36 possible outcomes when 2 dice are rolled.
Thus the probability of the sum being 4 = 3 / 36 = 1/12 (answer).
