-3|x|=9, what is x? I wrote that x = -3, but I guess that's wrong?
Answer:
no solution
Step-by-step explanation:
You want the solution to -3|x| = 9.
SignThe equation shows the product of a negative number (-3) and a positive number |x| is positive (9).
This is a violation of the rules of arithmetic. The product of a positive and a negative is always negative.
There is no solution to this equation.

Answer:
61.3 to infinty
Step-by-step explanation:
1. Multiple: 7(8) = 56
2. Multiple: 2(4) = 8
3. Divide: the result of step 2: 3 = 8 : 3 = 2.6666666666667 = 8/43
4. Multiple: the result of step 3: 4 = 8/3
* 4 = 8 · 4/
3 · 1
= 32/
3
5. Subtract: the result of step 1 - the result of step 4 = 56 - 32/3
= 56/1
- 32/3
= 56 · 3/1 · 3
- 32/3
= 168/3
- 32/3
= 168 - 32/3
= 136/3
6. Multiple: 2(8) = 16
7. Add: the result of step 5 + the result of step 6 = 136/3
+ 16 = 136/3
+ 16/1
= 136/3
+ 16 · 3/ 1 · 3
= 136/3
+ 48/3
= 136 + 48/3
= 184/3

- Meagan puts three flowering plants in a garden bed. Plant 1 and Plant 2 are 6 inches apart Plant 2 and Plant 3 are 10 inches apart Plant 1 and Plant 3 are 13 inches apart Did Meagan place the plants in a right triangle shape? Why or why notp?
Answer:
No
Step-by-step explanation:
They can't be in a straight line because 6+10 (the distance between plants 1 and 2 and plants 2 and 3) is more than 13 which is the distance from plant 1 to plant 3. This means plant 3 can't be in line with 1 and 2 which will give a triangular shape. If we check Pythagorean theorem we get 6^2 + 10^2 = 13^2 ( the longest side has to be the hypotenuse) . Since this isn't a true statement it can't be a right triangle.

It is given that the volume of a size 5 football is larger than that of a size 4 football by 72.8%.find the ratio of the radius of the size 5 football to that of the size 4 football.
Answer:
6/5
Step-by-step explanation:
Let size 4 football radius = x,
and size 5 football radius = y,
Volume of size 5 = Volume of size 4 × (1 + 0.728)
Using the sphere volume formula,
V = (4/3)πr³
(4/3)πy³ = (4/3)πx³ × (1.728)
y³ = 1.728x³
y = ³√1.728 x
y/x = 6/5
Therefore, ratio of the radius of the size 5 football to that of the size 4 football is 6/5
Answer:
6/5

Given a normal distribution with a mean of 28 and a standard deviation of 2.5, what percentage of the data should be between 25.5 and 30.5?
Using the Empirical Rule, it is found that 68% of the data should be between 25.5 and 30.5.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:
28 - 2.5 = 25.5.28 + 2.5 = 30.5.Within one standard deviation of the mean, hence, 68% of the data should be between 25.5 and 30.5.

ILL GIVE YOU BRAINLIST ANSWER!!
Answer:
5.946 cm
Step-by-step explanation:
Using the Pythagorean Theorem, we know that in a right angle triangle to find the longest side we must use the equation a^2 = b^2 + c^2
A is the longest side while b and c are the other two sides
To find one side we must use
b^2 = a^2 - c^2
a squared = 6.9 squared - 3.5 squared
a^2 = 35.36
square root 35.36 to get a
a = 5.946427499
a (3 d.p.) = 5.946

Answer:
[tex]\sqrt{29[/tex]
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2 = c^2. "a" and "b" represent the side lengths QR and PR, while "c" represents the hypotenuse PQ.
Let's plug in these values:
2^2 + 5^2 = c^2
4 + 25 = c^2
29 = c^2
sqrt 29 = c
Therefore "c" is the square root of 29.

You text your friend for 15 minutes on friday night and for 25 minutes on saturday night. what is the percent of increase? (round to nearest whole percent)
Answer:
66%
Step-by-step explanation:
This doesn't really require any equations, it's just brain work.
15 can be easily divided into 3 parts, each part consisting of 5 units. Here, it will be 5 minutes, then, if it's 5 minutes for each 33%(this number is rounded), then, that means that for 10 minutes, it will be 66%. You can understand this because the amount of increase in minutes is 10 minutes, and if each 5 minutes = 33% of increase, then 33+33=66, so hence, our answer is 66%.

The functions f(x) = x2 – 2 and g(x) = –x2 + 5 are shown on the graph.Explain how to modify the graphs of f(x) and g(x) to graph the solution set to the following system of inequalities. How can the solution set be identified? y > x2 – 2 y ≥ –x2 + 5
Two rigid transformations must be applied:
Vertical translation 7 units in the +y direction.Reflection around the line y = 5.The solution set can be identified by the fact that domain of quadratic functions is the real domain.
How to use rigid transformations
In the field of the Euclidean geometry rigid transformations are transformations applied on geometric loci such that Euclidean distances within the latter are conserved and herein we must determine what rigid transformations we should apply on f(x) to obtain g(x).
After a careful examination, we conclude that following two rigid transformations must be applied:
Vertical translation 7 units in the +y direction.Reflection around the line y = 5.The solution set represents the set of x-values such that the function exists. As both functions are quadratic equations, then their solutions are described the entire real domain.

O C. 45°

Answer:

Step-by-step explanation:
The measure of the angle ABC in the given circle is 60°
What is circle?A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the center). Any interval joining a point on the circle to the center is called a radius. By the definition of a circle, any two radii have the same length.
Given is a circle, with arcs DE and AC measuring 45° and 75° respectively,
We need to find the measure of the angle ABC,
So, using the property of a circle, we will have,
∠ ABC = 1/2 {arc DE + arc AC}
= 1/2 {45+75}
= 1/2 x 120
= 60
Hence, the measure of the angle ABC in the given circle is 60°
