Answer:
2,-12
Step-by-step explanation:
The given equation is ,
[tex]\implies |x + 5 | = -7 [/tex]
We know that modulus only gives positive value , Therefore on squaring both sides we have ,
[tex]\implies (x + 5 )^2=( -7)^2 \\\\\implies (x+5)^2=7^2\\\\\implies x + 5 =\pm 7 \\\\\implies x = 7-5,-7-5 \\\\\implies \boxed{ x = 2, -12} [/tex]

is AC greater than, less than, or equal to BC? explain your reasoning
Answer:
AC is greater than BC
Step-by-step explanation:
First, we know that the angle of a straight line is 180°, so angle B as a whole is equal to 180 degrees. Therefore, angle YBC + angle ABC = 180 degrees. As angle YBC is a right angle, signified by the small square on the angle, it is 90 degrees. Therefore,
90 degrees + angle ABC = 180 degrees
subtract 90 degrees from both sides to isolate angle ABC
angle ABC = 90 degrees
Therefore, as angle ABC is equal to 90 degrees, and a right angle is 90 degrees, triangle ABC has a right angle, making it a right triangle.
In a right triangle, using the Pythagorean Theorem, the square of the side opposite the right angle is equal to the sum of the squares of the other side. Since side AC is opposite the right angle, we can say that
AC² = AB² + BC²
As the length of a side has to be greater than 0, we can say that
AC² = AB² + BC²
AB² > 0
AC² > BC²
square root both sides
AC > BC
Therefore, AC is greater than BC

A drawer is filled with 2 black shirts, 7 white shirts, and 11 gray shirts.
One shirt is chosen at random from the drawer. Find the probability that it is not a black shirt.
Write your answer as a fraction in simplest form.
Answer:
Probability of the chosen T-shirt not being black will be equal to 9/10
Step-by-step explanation:
In order to solve this we need to understand that probaility is equal to the number of those outcomes that we want divided by the total number of outcomes. In our case the total number of outcomes is 20 (2 + 7 + 11) which is the total number of T-shirts, and the number of outcomes that are favorable to us is equal to 18 (outcomes without a black T-shirt). Therefor probability of the chosen T-shirt not being black will be equal to...

An ice cream cone is 4 in across and 6 in deep. A scoop of ice cream with a diameter of 4 inches is placed on top. If the ice cream completely melts, how much ice cream spills out of the cone? Round answer to two decimal places.
Answer:
8.373
Step-by-step explanation:
Cone
Find the volume of the cone
V = 1/3 pi r^2 h
r = d/2
r = 4/2
r = 2 inches
h = 6 inches
pi = 3.14
V = 1/3 * 3.14 * 2^2 * 6
V = 25.12
Half sphere
V = 1/2 (4/3) pi r^3
r = 2 from above calculation
pi = 3.14
V = 2/3 * 3.14 * 2^3
V = 2/3 * 3.14 * 8
V = 16.74
Nothing spills out so I scoop must be a whole sphere. The sphere is 2 times what I calculated it to be or
V = (4/3) * 3.14 * 2^3
V = 33.49 cubic inches
The difference in volume is 33.49 - 25.12 = 8.373
What is an equation of the line that is parallel to y = 3x - 8 and passes
through the point (4,-5)?
Answer:
[tex]y=3x-17[/tex]
Step-by-step explanation:
Parallel equations always share a slope.
So since we know the slope and a point the equation needs to pass through we can plug in the values and replace -8 with [tex]b[/tex]
[tex]-5=3(4)+b[/tex]
simplify both sides
[tex]-5=12+b[/tex]
isolate the variable
[tex]-17=b[/tex]
plug [tex]b[/tex] back into the equation and you get
[tex]y=3x-17[/tex]
Answer:
y = 3 x + 11
Explanation:
Parallel lines have the same slopes.
The slope of the new line will have the same slope as the given line:
y = 3 x − 4
⇒ m = 3
One point on the line is given,
( − 2 5 ) .
This is ( x 1 y 1 )
The formula for slope is
m = ( change in y values/ change in x-values ) = y 2 − y 1/ x 2 − x 1
If you have the slope and one point , substitute them into a formula which is based on the formula for slope given above.
y − y 1 = m ( x − x 1 )
y − 5 = 3 ( x − ( − 2 ) )
y − 5 = 3 ( x + 2 )
Simplify to get the required equation of the line.
y = 3 x + 6 + 5
y = 3 x + 11

which lines are perpendicular ?
Answer:
Lines C and D
Step-by-step explanation:
For a pair of lines to be perpendicular ,
the product of their slope must be - 1 .
Slope of A:

[tex]y = \frac{2}{3}x - 2\\\\slope_A = \frac{2}{3}[/tex]
Slope of B:
[tex]3x - 2y = - 9\\\\-2y = - 3x - 9\\\\y = \frac{-3x}{-2} - \frac{9}{-2}\\\\y =\frac{3x}{2} + \frac{9}{2}\\\\slope_B = \frac{3}{2}[/tex]
Slope of C:
[tex]y = - \frac{3}{2}x - 5 \\\\slope_C = -\frac{3}{2}[/tex]
Slope of D:
[tex]y = \frac{2}{3}x + 2\\\\slope_D = \frac{2}{3}[/tex]
Product of the slopes = - 1
[tex]slope_A \times slope_B = \frac{2}{3} \times \frac{3}{2} = 1 \neq - 1 \\\\Therefore, not\ perpendicular.\\\\Slope_B \times slope_C = \frac{3}{2} \times \frac{-3}{2} = \frac{-9}{4} \neq -1\\\\Therefore , not \ perpendiucalr.\\\\Slope_C \times slope_D = -\frac{3}{2} \times \frac{2}{3} = - 1\\\\Therefore , perpendicular\\\\\\Slope_A \times slope_D = \frac{2}{3} \times \frac{2}{3} = \frac{4}{9} \neq 1\\\\therefore , not \ perpendicular.[/tex]

Answer:
[tex]j = - 0.45[/tex]
Step-by-step explanation:
Combine like terms and apply the rules of algebra.
[tex]2.25 - 11j - 7.75 + 1.5j = 0.5j - 1[/tex]
[tex] - 5.5 - 9.5j = 0.5j - 1[/tex]
[tex] - 9.5j = 0.5j + 4.5[/tex]
[tex] - 10 j= 4.5[/tex]
[tex]j = - 0.45[/tex]
Answer: j = -0.45
Step-by-step explanation:
Step 1: Combine like terms
2.25 - 11j - 7.75 + 1.5j = 0.5j - 1
-5.5 - 9.5j = 0.5j - 1
Step 2: isolate your variable
-5.5 - 9.5j = 0.5j - 1
Subtract 0.5j from both sides
-5.5 - 10j = -1
Add 5.5 to both sides
-10j = 4.5
Divide both sides by -10
j = -0.45

Prove that the value of the expression: (3^5 - 3^4)(3^3 + 3^2) is divisible by 24. Answer format: The value of the expression is 24 • __
Step-by-step explanation:
(3^5 - 3^4) (3^3 + 3^2)
= (243 - 81) (27 + 9)
= (162) (36)
= 5832
24 = 8*3
since 832 is divisible by 8 and 5+8+3+2 = 18 is divisible by 3
5832 is therefore divisible by 24
check:
5832/24 = 243

p = [?]
Enter a decimal rounded to the nearest hundredth.
Answer:
Answer is 0.14.
Step-by-step explanation:
The probability that a student earns a grade of D or F is 0.14.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To find the probability that a student earns a grade of D or F, we need to add the frequencies of these two grades and divide by the total number of students:
P(D or F) = (3 + 2) / 35
P(D or F) = 5 / 35
P(D or F) = 0.14 (rounded to the nearest hundredth)
Therefore,
The probability that a student earns a grade of D or F is 0.14.

Solve for e. 4/3 = -6e - 5/3
Answer:
e = -1/2
Step-by-step explanation:
To solve this problem, our first step is to add 5/3 to both sides of the equation. This gives us:
4/3 + 5/3 = -6e - 5/3 + 5/3
9/3 = -6e
We can simplify the left side of the equation by performing the division.
3 = -6e
Next, we can solve for e by dividing both sides of the equation by -6.
e = -1/2
Therefore, the correct answer is e = -1/2.
Hope this helps!
Answer:
The value of e is -1/2
Step-by-step explanation:
4/3 = - 6e - 5/3
Now, add 6e both side we get,
4/3 + 6e = + 6e - 6e - 5/3
4/3 + 6e = - 5/3
Now, subtract 4/3 from both side we get,
4/3 - 4/3 + 6e = -4/3 - 5/3
6e = -4/3 - 5/3
6e = -4 - 5/3
6e = -9/3
6e = -3
Now, divide 6 from both side we get,
6e/6 = -3/6
e = -1/2
Thus, The value of e is -1/2
