Answer:
(f + g)(2)=14
Step-by-step explanation:
If f(x) = 2x^2 + 3x
g(x) = x - 2
(f + g)(2)
Lets find
(f+g) (x)
We add the 2 functions
(f+g) (x)=2x^2 + 3x + x - 2
Combine like terms
(f+g) (x)=2x^2 + 4x - 2
Now we let x=2
(f+g) (2)=2(2)^2 + 4(2) - 2
(f+g) (2)=2(4) + 8 - 2
=8+8-2
=14
Answer:
LARGER NUMBER IS 15 AND SMALLER NUMBER IS 9
Step-by-step explanation:
LET THE LARGER NUMBER BE X AND SMALLER BE Y
X + Y = 24 …….1
X = 6 + Y …… 2
WE SOLVE SIMULTANOUSLY
SUBTRACTNG EQATION 2 FROM 1
X – X + Y – (-Y) = 24 – 6
Y + Y = 18
2Y = 18
DIVIDING EACH TERM BY 2
2Y/2 = 18/2
Y = 9
THEN PUTTING Y = 3 IN EQUATION 2
X = 9 + 6
X = 15

Y = 2/5x + 3. The slope here is 2/5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal. we " flip " the slope and change the sign. So the perpendicular line will need a slope of -5/2.
y = mx + b
slope(m) = -5/2
(4,-4)....x = 4 and y = -4
now we sub and find b, the y int
-4 = -5/2(4) + b
-4 = - 10 + b
-4 + 10 = b
6 = b
so ur perpendicular line is : y = -5/2x + 6
Answer:
What is the probability formula?
Image result
In general, the probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
