#4 . Simplify the expression 2(x − 8) + 2(12). *
Answer:
x = -4
Step-by-step explanation:
2x-16+24 = 2x+8
2x = -8
x = -4
Hey there!
2(x - 8) + 2(12)
DISTRIBUTE 2 WITHIN PARENTHESES
= 2(x) + 2(-8) + 2(12)
= 2x - 16 + 24
COMBINE the LIKE TERMS
= 2x + (-16 + 24)
= 2x + 8
Therefore, your answer is: 2x + 8
Good luck on your assignment & enjoy your day!

Answer:
slope = 4/1 or 4
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
Use the slope formula. change in y/change in x. The change in y is 4 because if your subtract the y coordinate 4 from the y coordinate 8, you get 4. The change in x is 1 because if you subtract the x coordinate 2 from the x coordinate 3, you get 1. 4 (change in y)/1 (change in x) is 4. Hope this helps!

Find any points of discontinuity for y = 5x+6/x2+6x+9
Answer:
x = -3 is the point of discontinuity.
Hence, option B is correct.
Step-by-step explanation:
Given the expression
[tex]y=\frac{5x+6}{x^2+6x+9}[/tex]
In order to determine the discontinuity, the denominator must be 0.
so let us solve the denominator to get the values of x
[tex]x^2+9x+9\:=0[/tex]
[tex]\left(x+3\right)^2=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]x+3=0[/tex]
Subtract 3 from both sides
[tex]x+3-3=0-3[/tex]
[tex]x = -3[/tex]
Therefore, x = -3 is the point of discontinuity.
Hence, option B is correct.

It is given that at x = 1, the function x^4 - 62x^2 + ax + 9 attains its
maximum value on the interval [0, 2]. Find the value of a.
Answer:
The value of a is 120.
Step-by-step explanation:
Given function;
f(x) = x⁴ - 62x² + ax + 9
find the derivative of the function;
f'(x) = 4x³ - 124x + a
The function (f) attains its maximum value on the interval [0, 2], at x = 1.
f'(1) = 0
0 = 4(1)³ - 124(1) + a
0 = 4 - 124 + a
0 = -120 + a
120 = a
Thus, the value of a is 120.

The probability that a women likes the color blue is 10%. The probability of being a women is 40%.What is the probability that a person likes the color blue given that they are a woman?
Answer:
The probability that a person likes the color blue given that they are a woman=0.25%
Step-by-step explanation:
We are given that
The probability that a women likes the color blue=10%=[tex]\frac{10}{100}=0.1[/tex]
The probability of being a women=40%=[tex]\frac{40}{100}=0.4[/tex]
We have to find the probability that a person likes the color blue given that they are a woman.
We know that
Conditional probability formula
[tex]P(A/B)=\frac{P(A\cap B)}{P(B)}[/tex]
The probability that a person likes the color blue given that they are a woman
=[tex]\frac{0.1}{0.4}[/tex]
[tex]=\frac{1}{4}=0.25[/tex]
Hence, the probability that a person likes the color blue given that they are a woman=0.25%

Answer:
B. BD = 67Step-by-step explanation:
ABCD is a square.
BD and AC are diagonals and they have equal length.
We have AC = 7x + 18 and BD = 10x - 3
Since AC = BD, we substitute their values and solve for x:
7x + 18 = 10x - 310x - 7x = 18 + 33x = 21x = 21/3x = 7Then find the length of BD:
BD = 7x + 18 = 7*7 + 18 = 49 + 18 = 67Correct option is B. BD = 67
The probability of selecting 3 female employees and 7 male employees to win a promotional trip a company with 10 female and 50 male employees would best be modeled with the _______.
Answer:
The best model is hypergeometric distribution.
Step-by-step explanation:
The probability would be best modeled with hypergeometric distribution.
Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.
The hypergeometric distribution differs from the binomial distribution in the lack of replacements.
Thus, the best model is hypergeometric distribution.
Matthew purchased a desk that was on sale for 45% off the orginal price of $480.If the sales tax was 8% (of the sale price), how much did mattew spend on the desk
Answer:
285.12
Step-by-step explanation:
discount amount = 45/100 x 480= 45x48/10
=216.0
price after discount= 480-216=264
sales tax= 8/100 x 264=21.12
total money spent = 264+21.12=285.12
45% of 480
= 45/100 x 480
= 0.45x480
=216
=480-216
=264
8% of 264
= 8/100 x 264
= 0.08 x 264
= 21.12
= 264 + 21.12
=285.12
Therefore, he paid $285 and 12 cents

you have 15 milk chocolate Valentines and 10 dark chocolate Valentine.What is the probability that the first Valentine handed out is milk chocolate and the second is dark chocolate.
Answer:
15/25 cuz 25 is the total and there's 15 milk. 2nd as dark chocolate would then be 10/24 cuz you've already taken one chocolate. Multiply by both would be 3/5 × 5/12 = 1/4. Percentage would then be 1/4 = 0.25 , and multiply that by 100% would then be 25%
Answer:
probability of getting milk chocolate =3/5
while
the probability of getting dark chocolate is 2/5
Step-by-step explanation:
milk chocolate=15
dark chocolate=10
there fore total=25
probability of getting milk chocolate=15/25. =3/5
while
the probability of getting dark chocolate=10/25=2/5

Answer:
2.73 or [tex]\frac{273}{100}[/tex]Step-by-step explanation:
[tex]--------------------------------------------[/tex]
It is $2.73 because 7% of $39 = 2.73 or [tex]\frac{273}{100}[/tex] according to Desmos.
[tex]--------------------------------------------[/tex]
$39 + $2.73 = $41.73 = Total

ANSWER ASAP PLS YEY BRAINLIEST AND STUFFsolve for x 2/3=x-1/5
Answer:
x = 13/15
Step-by-step explanation:
If x - 1/5 = 2/3,
you can find x by doing 2/3 + 1/5.
2/3 = 10/15
1/5 = 3/15
10/15 + 3/15 = 13/15!

Answer:
y +3 = -2(x +4)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
For your given point and slope, this is ...
y -(-3) = -2(x -(-4))
y +3 = -2(x +4)
