Answer:
11
Step-by-step explanation:
When you plug in -2 for x you get -4(-2) +3
8 +3 = 11
F(-2)=11

Answer:
Ques 1) 1440°
Ques 2) 4000
Ques 3) 33
Step-by-step explanation:
Ques 1)
The sum of the measures of the angles in degrees of a polygon with 'n' sides is given by: 180×(n - 2).
Now we have to find the sum of the measures the angles of a polygon with 10 sides.
i.e. n=10
Hence the value of the expression 180×(n-2) when n=10 is given by:
180×(10-2)=180×8=1440.
Hence, the sum of measure of the angles of a polygon with 10 sides is: 1440°.
Ques 2)
The Expression 500v gives the number of points a player earns for completing v voyages in video game.
We are asked to find the number of points earned for completing 8 voyages.
i.e. v=8 the value of 500v will be 500×8=4000.
Hence, 4000 points are earned for completing 8 voyages.
Ques 3)
we have to find the value of the question as given in the figure:
7x+y+16 for x=2 and y=3.
Hence, we find the value of the expression:
7×2+3+16=33.
Hence, the value of the expression is 33.
I think it is $900 because .15* 6000 is 900. This means Victoria needs to pay $900. <span />
4. (9x^2 + 13x) + (4x^2 - 8x)
(9x^2 + 13x)
9x^2 = 81 x + 13 x = 94x
(4x^2 - 8x)
4x^2 = 16x - 8x = 8x
94x + 8x = 102x
The answer is 102x
5. (x^2 + 4x + 6) + (x^2 + 8x + 3)
(x^2 + 4x + 6)
4x + 6 = 10x
10x + x^2 = 10x^2
(x^2 + 8x + 3)
8x + 3 = 11x
x^2 + 11x = 11x^2
The answer i 11x^2
6. (-3x^2 + 2x - 8) + (x^2 + 4x)
(-3^2 + 2x + 8)
-3^2 = 9
2x + 8 = 10x
10x + 9 = 19x
(x^2 + 4x)
x^2 + 4x = 4x^2
19x + 4x^2 = 23x^2
The answer is 23x^2.
Answer:
Suppose that x is some number so 6 times a number is 6*x. 20 more than that number is 20 + x. If you put it together the inequality would be 6x > 20 + x. Subtracting x from both sides would result in 5x > 20. Dividing by 5 gives you x > 4 which is the final answer. So the possible values of that number is anything greater than 4.
