A charm bracelet costs $65, plus $25 for each charm. The equation -25x+y=65 represents the cost y (in dollars) of the bracelet, where x is the number of charms.
a. Graph the equation.
b. How much does a bracelet with three charms cost?
Answer:
a. see attached
b. $140
Step-by-step explanation:
a.The graph starts at y=65 when x=0 and increases by 25 for each increase of 1 in x. The attachment shows a graph of the equation.
__
b.Use x=3 in the equation.
-25x +y = 65
y = 65 +25x = 65 +25(3) = 140

Answer:
the period of this graph is [tex]\pi[/tex]
Step-by-step explanation:
The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.
Let's look at the peaks (maximums).
One is at x = 0 and the next is at x = [tex]\pi[/tex]
[tex]\pi[/tex] - 0 = [tex]\pi[/tex]
Therefore, the period of this graph is [tex]\pi[/tex]

Step-by-step explanation:
<3 and <2 are on a straight line.a straight line is 180° .so <3 +<2=180.angles which add up to 180 ° are said to be supplement
The best statement in geometric proof that proves the theorem that vertical angles are equal [tex]\angle2 + \angle3 = 180^{\circ}[/tex] because ∠2 and ∠3 are linear pair.
In the given proof, where the angles are labeled as ∠1, ∠2, ∠3, and ∠4, demonstrate the equality of vertical angles by utilizing the concept of a linear pair:
Step 1: Given two lines intersect.
Step2:
State that ∠1 and ∠2 are adjacent angles, as they share a common side.Introduce the concept of a linear pair, which states that if two angles form a straight line, their measures sum up to 180°. Since ∠1 and ∠2 form a straight line, their measures sum up to 180 degrees. Express the equation: [tex]\angle1 + \angle2 = 180^{\circ}[/tex].Step 3:
Demonstrate that ∠2 and ∠3 are also adjacent angles, sharing a common side.Apply the linear pair concept to ∠2 and ∠3, resulting in the equation: [tex]\angle2 + \angle3 = 180^{\circ}[/tex].Step 4:
By comparing the equations [tex]\angle1 + \angle2 = 180^{\circ}[/tex] and [tex]\angle2 + \angle3 = 180^{\circ}[/tex], deduce that ∠1 and ∠3 are equal angles.By following this step-by-step geometric proof, establish that the best statement to prove the theorem "Vertical angles are equal when two lines intersect" is the statement that defines vertical angles as "Vertical angles are formed by adjacent angles sharing a common side

Answer:
w = 90.Step-by-step explanation:
We need to convert the fraction into a whole number.
We have to solve 11 + 19 first:
11 + 19 = 30.30/3 = 10 so we need to increase the numerator:
30 * 3 = 90.90/3 = 30.90/3 - 11 = 19.w = 90.Answer:
90
Step-by-step explanation:
First we take 11 to other side to give:
[tex]\frac{w}{3} = 19+11[/tex]
[tex]\frac{w}{3} = 30[/tex]
Now we escalate the 3 up to give
w = 30×3
w=90
To double check we can substitute our value of w into the original equation:
[tex]\frac{90}{3}-11 = 19[/tex] ✅

In a pair of vertical angles one
angle measures 46° and the
other is (2x+7)º. Determine the
value of x.
Answer:
19.5
Step-by-step explanation:
We are given the pair of angles are vertical angles, meaning they are congruent or equal. We can use this to set up an equation to solve for x...
46=2x+7
Subtract 7 from both sides
39=2x
Divide both sides by 2
x=19.5
Normal Distribution (Standard deviation)
Image attached! Due in 1 hour! please help!
I don't know what kind of calculator you have at your disposal, so I'll just give one way of computing the sample mean and standard deviation.
• To get the mean, add up all the data points and divide the total by the number of data:
[tex]\bar x = \displaystyle \sum_i \frac{x_i}n = \frac{1243+1264+\cdots+1275}9 \approx 1273.89 \\ \implies \boxed{\bar x \approx 1274}[/tex]
• To get the s.d. s, first compute the variance s² by adding up the squared difference between each of the data points and the sample mean, and divide the total by 1 less than the number of data:
[tex]s^2 = \displaystyle \sum_i \frac{\left(x_i-\bar x\right)^2}{n-1} = \frac{(1243-1274)^2+(1264-1274)^2+\cdots+(1275-1274)^2}8 \approx 1211.61[/tex]
The s.d. is the square root of the variance:
[tex]s^2 \approx 1211.61 \implies s \approx 34.8082 \implies \boxed{s\approx 35}[/tex]
The 90% confidence interval for the sample mean has upper and lower limits, respectively, of
[tex]\bar x \pm \dfrac{\left|Z_{\alpha/2}\right| s}{\sqrt n}[/tex]
(positive root for upper limit, negative root for lower limit)
where [tex]Z_{\alpha/2}[/tex] is the critical value for a (1 - α)×100% confidence level. By critical value, I mean
[tex]\mathrm{Pr}\left[ Z \le Z_c \right] = c[/tex]
where Z is a random variable following the standard normal distribution.
In this case, we have a 90% confidence level, so α = 0.1, and the critical value is [tex]Z_{0.05} \approx -1.64[/tex]. Then the confidence interval has upper limit
[tex]\bar x + \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 + \dfrac{1.64 \times 35}{\sqrt9} \approx 1292.97 \approx \boxed{1293}[/tex]
and lower limit
[tex]\bar x - \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 - \dfrac{1.64 \times 35}{\sqrt9} \approx 1254.8 \approx \boxed{1255}[/tex]

At her last practice she made 70% of her shots from the free throw line if she shot the ball 130 times
How many times did she make a free throw?
How many times did she miss? What percentage of her shots did she miss?
Answer:
1. She made 91 shots.
2. She missed 30% of her shots, or 39 shots.
Step-by-step explanation:
1. 70% of 130 (or .7 times 130) is 91. The 70% is converted into decimals by moving the decimal 2 places to the left.
2. Out of 100%, 30% is the added percentage to make 100%. 30% of 130 (or .3 times 130) is 39. This can also be found my subtracting 91 from 130.

Can the sides of a triangle have lengths 4, 7, and 10?
yes
no
Answer:
i kinda like ixl but the answer is yes
Step-by-step explanation:
Yes these side lengths can make a triangle
The triangle side length rule states that any 2 sides of a triangle are greater than the other side.
Let's use this rule to determine if these side lengths can make a triangle.
4+7=11 and 11 is greater than 10.
4+10=14 and 14 is greater than 7.
7+10=17 and 17 is greater than 4.
These side lengths can make a triangle.
