When solving a system of equations, Jared found y = x + 10 for one equation and substituted x + 10 for y in the other equation. Nicole found x = y – 10 for the same equation and substituted y – 10 for x in the other equation. Who is correct? Explain.
Jared is correct because if you substitute a random number in for x 2 for example
2+10=12
2-10 doesn’t =12
Answer:
Both Jared and Nicole are correct. You can solve for either variable and use the equivalent expression to create a one-variable equation. Then you can solve. Jared would have created a one-variable equation that can be used to solve for x, whereas Nicole would have created a one-variable equation that can be used to solve for y.

Now use the distance formula to find the length of line segment:
[tex]\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
The distance between (-2,3) and (-5,1) is:
[tex]\overline{DE}=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-3\right)^2}=\sqrt{13}[/tex]
The distance between (-5,1) and (-3,-2) is:
[tex]\overline{DF}=\sqrt{\left(-3-\left(-5\right)\right)^2+\left(-2-1\right)^2}=\sqrt{13}[/tex]
The distance between (-3,-2) and (-2,3) is:
[tex]\overline{EF}=\sqrt{\left(-2-\left(-3\right)\right)^2+\left(3-\left(-2\right)\right)^2}=\sqrt{26}[/tex]
Hence the length of line segment DE and DF is same.
Thus the correct option is A) [tex]\overline{DF}\cong \overline{DE}[/tex]

Use the function below to find f(3) f(x)= (1/6)^x
The answer is:
[tex]f(3)=(\frac{1}{216})[/tex]
Why?To find the required function f(3), we need to use the given function f(x) and evaluate "x" equal to 3 (input).
We are given the function:
[tex]f(x)=(\frac{1}{6})^{x}[/tex]
Then, evaluating "x" equal to 3, we have:
[tex]f(3)=(\frac{1}{6})^{3}[/tex]
[tex]f(3)=(\frac{1}{6})^{3}=(\frac{1}{6})*(\frac{1}{6})*(\frac{1}{6})=(\frac{1}{6*6*6})[/tex]

The angles in a triangle are in the ratio 1:2:3. Show that the triangle is a right - angled triangle.
Answer:
Angles in a triangles add up to 180°
Respectively 1 : 2 : 3 is going to be 1 x , 2 x and 3 x so,
1 x + 2 x + 3 x = 180°
⇒ Simplify
6 x = 180°
⇒ Divide by 6 on both sides to isolate x
x = 30°
Since the ratio was 1 x : 2 x : 3 x and x is 30°,
30 : 60 : 90
And since there is a 90° angle, it is a right - angled triangle

Answer: [tex]d=11[/tex]
Step-by-step explanation:
To find the value of "d" you need to solve for "d" from the equation given
[tex]2d -5=17[/tex]
First, you have to apply the Addition property of equality and add 5 to both sides of the equation. Then:
[tex]2d -5+(5)=17+(5)\\2d=22[/tex]
And finally, you have to apply the Division property of equality and divide both sides of the equation by 2.
Therefore, you get that the value of "d" is:
[tex]\frac{2d}{2}=\frac{22}{2}\\\\d=11[/tex]
Please give Brainliest!
Answer: The value of d is 11
Step-by-step explanation:
To find the value of "d" you need to subtract five from 2d or 2•11 which would give you 17.
2d -5=17
First you would add five to each side.
2d -5 + 5=17+5
This would show you that whatever you multipy 2 by would have to equal 22.
2d=22
The only thing times 2 that equals 22 is 11, so that would have to be your answer.

A 3-gallon bottle of bleach costs $13.92. What is the price per cup?
To calculate the cost per cup of bleach, first convert the quantity from gallons to cups. A 3-gallon bottle equals 48 cups. Divide the total cost ($13.92) by the total number of cups (48) to determine the cost per cup, which is $0.29.
Explanation:This problem involves finding out the unit cost or, in this case, the cost per cup of bleach. One gallon is equivalent to 16 cups, hence a 3-gallon bottle is equivalent to 48 cups.
So, if $13.92 buys you 48 cups, you can calculate the cost per cup by dividing the total cost by the number of cups.
Proceed with the following calculation: $13.92 costs /48 cups = $0.29 per cup of bleach costs.
In conclusion, each cup of bleach from this 3-gallon bottle would cost you $0.29.

To find the price per cup of bleach from a 3-gallon bottle costing $13.92, we multiply 3 gallons by 16 cups per gallon to get 48 cups, and then divide $13.92 by 48 to find the cost per cup, which is approximately $0.29.
Explanation:To calculate the price per cup of bleach when given the price per gallon, we need to know how many cups are in a gallon and then divide the total cost by the total number of cups.
First, we establish that there are 16 cups in a gallon. Since we are dealing with a 3-gallon bottle, the total number of cups will be 3 gallons times 16 cups per gallon, which equals 48 cups.
Next, we take the total cost of the 3-gallon bottle, which is $13.92, and divide it by the total number of cups, 48. Performing this division gives us the cost per cup. So, $13.92 divided by 48 cups equals approximately $0.29 per cup.
This method demonstrates how to break down bulk costs into more manageable unit prices and can be applied across various products and measurements.

Find x in the figure below.
Answer:
B. 25
Step-by-step explanation:
We can use the altitude theorem, to quickly find the value of x.
According to this theorem; the altitude of the triangle is equal to the geometric mean of the product of the two segments created by the leg of the altitude on the hypotenuse.
We apply this theorem to obtain:
[tex]10=\sqrt{4x}[/tex]
This implies that:
[tex]10^2=4x[/tex]
[tex]100=4x[/tex]
Divide both sides by 4 to obtain:

identify the relative maximum value of g(x) for the function shown below
g(x) = 2/ x^2 +3
Answer:
The relative maximum value is [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The given function is
[tex]g(x)=\frac{2}{x^2+3}[/tex]
We differentiate to obtain;
[tex]g'(x)=-\frac{4x}{(x^2+3)^2}[/tex]
At turning points [tex]g'(x)=-\frac{4x}{(x^2+3)^2}=0[/tex]
[tex]\implies x=0[/tex]
[tex]g''(x)=\frac{16x^2}{(x^2+3)^3}- \frac{4}{(x^2+3)^2}[/tex]
We apply the second derivative test to obtain:
[tex]g''(0)=\frac{16(0)^2}{((0)^2+3)^3}- \frac{4}{((0)^2+3)^2}=-\frac{4}{9}[/tex]
Since the second derivative is negative, there is a relative maximum at x=0.
We substitute x=0 into the original function to obtain the relative maximum value.
[tex]g(0)=\frac{2}{(0)^2+3}=\frac{2}{3}[/tex]
To find the relative maximum value of g(x) = 2/(x² + 3), one should evaluate the function at x = 0, giving the relative maximum value as 2/3.
The question is asking to identify the relative maximum value of the function g(x) = 2/(x² + 3).
To find the relative maximum, we need to find the critical points by taking the derivative of g(x) and setting it to zero. However, this function does not have a simple expression where the derivative is zero.
Instead, we note that because the denominator x² + 3 is always positive and has a minimum when x = 0, the function g(x) will have a maximum value when x = 0.
Thus, the relative maximum value of g(x) is obtained by plugging x = 0 into the function: g(0) = 2/(0² + 3) = 2/3.
