Answer:
an infinite number of solutions
Step-by-step explanation:
−3x −17 = −17 −3x
left side = right side TRUE because -3x-17 is the same as -17-3x
we can rearrange the the equation
−3x −17 +17 = −17 +17−3x, add 17 on both sides of the equations
-3x = -3x, divide both sides by (-3)
x = x
Since this equation is always true ( for any number ) we have an infinite number of solutions (since there are is an infinity of numbers.)

m<3=(7x-10) and m<6=(5x+10)
Step-by-step explanation:
m∠3 = 7x - 10
m∠6 = 5x + 10
m∠3 = m∠6
7x - 10 = 5x + 10
7x - 5x = 10 + 10
2x = 20
x = 20/2 = 10°

A test statistic is a statistic that is used to test statistical hypotheses. The test statistic of the given hypothesis is; C: -0.25
What is the test statistic?A test statistic is a statistic that is used to test statistical hypotheses. A test statistic is a numerical summary of a data set that lowers the data to a single number that can be used to perform the hypothesis test.
As it is given to us that the sample mean(x') is 36.63 hours, while the standard deviation(σ) is 13.23.
Now, we want to know whether Americans work less than 40 hours or not. therefore, let's first define the hypothesis;
Alternative Hypothesis; μ < 40
Null Hypothesis; H₀: μ ≥ 40
Further, the Formula for test statistics is given,
[tex]z = \dfrac{(x'-\mu)}{\sigma}\\\\z = \dfrac{(36.63- 40)}{13.23}\\\\z = -0.25[/tex]
Hence, the test statistic of the given hypothesis is; C: -0.25.

Step-by-step explanation:
Hello! I have a project where I invite 5 people to a “dinner party” to school. I want to invite a girl named Jaci Butler. Jaci Butler is her own agent in the singing industry. I found her address and want to send her a mail inviting her to the party. The party is at school. Does this count as stalking? If you were Jaci butler, what would you think I’m a stalker? If you were her, would you come?
REMEMBER: IM NOT INVITING HER TO MY HOUSE. IM INVITING HER TO MY SCHOOL
It's s tu pid if you really consider the question. No one hosts a 'dinner party' at school.. & that too with just 5 people. Utter ma dness, but if you really do invite an A-list celeb then she won't come unless there are audiences (in a huge number), other celebs, reporters etc. Plus you'll also need prior appointment. If you have all these then it's not sta lki ng..but that's not what happens in a dinner party & it's gonna cost a lot of money too. Now, this Jaci Butler you talk of is a singer-songwriter & you tuber..might not be a really big celeb (like Taylor Swift or Arianna Grande) or something but still calling her late at night to a school with 5 people sounds we ird & while it's not considered as s ta lking to me ...no person in their right mind would actually do it. St alking is like when you follow a person around making the other person uncomfortable with your presence. You hardly did that in this case...but calling Jaci to a dinner party at school is still c re epy. So, if I were Jaci I sure wouldn't come.

Answer: A
Step-by-step explanation:
If you plug in the numbers from the x column into the equation in the place of x, you can figure out the answer.
Example: -10x - 15
-10(1) - 15 = -25
-10(2) - 15 = -35 and so on...

plssss help me i'll give u 40 points evaluate: 3/5^-2
Answer:
75
Step-by-step explanation:
5^-2 = 5*5 = 25/1
because it's (-) you need to flip it so 1/25
3/1 ÷ 1/25 = 3/1 × 25/1
because when you divide fraction you need to keep the first fraction as it is and change the symbol from (÷) to (×) and flip the second fraction. (KCF simple way to memorise it)
So 3/1 × 25/1 = 75/1
75/1 is same as 75

Find the length in the kite labeled x
12 in.
9 in.
13 in
Answer:
15 in
Step-by-step explanation:
You have to use pythagoras' theorem, which is a^2=b^2+c^2 (a being the hypotenuse), because it is a right-angled triangle.
so you do 9^2+12^2, which equals 225. Then you square root that to get 15.

Todd purchased a jumper for his infant son. The jumper clamps to the top of a door frame and has a spring from
which the body of the jumper hangs to allow the infant to jump up and down. Included with the jumper are small
weights, each identical in
weight and size. The weights allow the user to adjust the initial height of the jumper by
stretching the spring a certain distance. Todd adds 8 of the weights and notes the spring stretches 2 centimeters.
a. According to Hook's Law, the amount that a spring is stretched, s, varies directly with the force applied to the
spring by the weights, F. Write an equation that relates F and s for the spring on the jumper
b. Using your equation from part a, find the stretch in the spring if Todd applies 14 of the included weights to the
spring
c. Using your equation from part
Hooke's law relates the force applied on an elastic material to its extension. Therefore, the answers to the questions are:
a. F = ks
b. The spring stretched 0.035 m (3.5 cm) when a weight of 14 N is included.
Hooke's law states that provided the extension limit of an elastic material is not exceeded, the force applied is directly proportional to its extension.
i.e F = ke
where F is the force applied to the material, k is the spring constant of the material, and e is the extension.
Considering the conditions in the given question then, we have:
a. The equation that relates F and S for the spring on the jumper is:
F = ks
b. Given that: F = 8 N, while s = 2 cm (0.02 m).
Then;
F = ks
8 = k(0.02)
k = [tex]\frac{8.0}{0.02}[/tex]
= 400
k = 400 N/m
So that, the stretch in the spring when 14 N weight is included is:
F = ks
14 = 400 x s
s = [tex]\frac{14}{400}[/tex]
= 0.035
s = 0.035 m
Thus the spring was stretched by 0.035 m (3.5 cm) when a weight of 14 N was included.
