X could be either 6 or -10
1+|2+x|=9
|2+x|= 9-1
|2+x|= 8
x could be 6 because 2+6=8
x could also be -10 because the final answer inside the '| |' becomes positive
|2+-10|=8
|-8|=8
8=8
Thus x could be 6 or -10

1 + |2 + x| = 9
| 2 + x | = 9 - 1
| 2 + x| = 8

2 + x = 8            -(2 + x) = 8
x = 8 - 2              -2 - x = 8
x = 6                    -x = 8 + 2
                            -x = 10
                             x = -10

solutions are : x = 6 or x = -10

Round 487.010 to the nearest whole number. Enter your answer in the space<br> provided
saw5 [17]

Answer:

487

Step-by-step explanation:

The answer is 487 because you must look one place to the right of the whole number for the rounding digit on the right side of the decimal point which is 0. Then you round down since the digit is not greater than 5.

Please help! I’ll give you brainliest immediately
kodGreya [7K]

For the lines to be parallel the two angles need to be equal to each other:


128-x = x

Add 1x to both sides

128 = 2x

Divide both sides by 2:

X = 128/2

X = 64


Answer: x = 64

Anyone who plays or watches sports has heard of the "home field advantage." Teams tend to win more often when they play at home.
AveGali [126]

Answer:

H0 : μ = 0.5

H0 : μ > 0.5

Kindly check explanation

Step-by-step explanation:

H0 : μ = 0.5

H0 : μ > 0.5

We perform a right tailed test :

Sample proportion :

Number of games won, x = 142

Number of games, n = 250

phat = x / n = 142 / 250 = 0.568 = 56.8%

Yes, it is consistent

Test statistic :

(phat - p) * √Phat(1-Phat)/n

1 -Phat = 1 -0.568 = 0.432

(0.568 - 0.5) /√(0.568*0.432)/250

0.068 / 0.0313289

= 2.17

The Pvalue using the z test statistic :

Pvalue = 0.015

α = 0.03

Since ;

Pvalue < α ; We reject the null and conclude that teams tend to win more often when they play at home.

A right triangle has sides of length 3, 4, and .
olchik [2.2K]

Answer:

5/hypotenuse, the square root of 7/ leg

Step-by-step explanation:

3^2+4^2=25 or 5^2. you use a^2+b^2=c^2. it would be one of the hypotenuses. If the missing number is a leg, you would do 4^2=3^2+x^2. 16=9+x^2, 7=x^2, so you plug in the numbers differently.

PLZZZZZ HELP I WILL GIVE BRAINLEST POINTS AND EXTRA POINTS
Greeley [361]

Answer:

a. Non proportional

b. Proportional

c. Non proportional

Step-by-step explanation:

Here, we want to determine if each situation is proportional or not

a) Non-proportional

This is because the amount y paid in a month will be;

y = 1400x + 150

Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship

b) proportional

y = 3/4x

The value of y is dependent solely on that of x, so the relationship is proportional

c) non proportional

Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional
