Hello :
A) it is an even function because for all x in R :
f(-x) = 2(-x)²+1
= 2x²+1
f(-x) = f(x)

Simplify 4+(9×2)÷(4-2)+1

kogti [31]

First we have to work out everything inside the parentheses (according to PEMDAS):

9 × 2 = 18

4 - 2 = 2

Now, we can rewrite the expression:

4 + 18 ÷ 2 + 1

According to PEMDAS, we should complete the division in the middle first:

18 ÷ 2 = 9

Now we can rewrite the expression again:

4 + 9 + 1

And now it's as simple as just adding the three numbers together:

4 + 9 + 1 = 14

Your final answer is 14. :)

Is x = -7, the solution to -11 + 2x = -26? Justify your answer in complete sentences.

Natali5045456 [20]

First of all, you can move the +2x to the other side:
-11 = -26 - 2x

Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x

Then you can divide both sides by 2:
7.5 = -x

Then you can flip the sides and the signs around:
x = -7.5

No, The answer is not -7, it is -7.5
Hope this helps! :)

The manager of a vacation resort believes that the ages of adult visitors to the resort can be modeled by a normal distribution.

8090 [49]

Step-by-step explanation:

(a) A histogram is like a bar graph, but with ranges instead of values.

(b) The distribution is approximately uniform, with slightly more people at the younger and older ends than in the middle.

(c) The ages do not appear to come from a normal distribution. Normal distributions are bell-shaped, tall in the middle and short on the sides.

2t + 8 is greater than or equal to -4 ( t + 1 ), whats the answer to the equation?

Natali [406]

Step-by-step explanation:

2t + 8 > - 4( t + 1)

2t + 8 > - 4t - 4

2t + 4t < - 4 +8

6t < 4

Divide both sides by 6

T < 4

t < 2

I think that is the answer

Hope it helps :)

Please be careful about the sign
