Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Jenny explains that this is not the most efficient way to solve. Explain who is correct & justify your reasoning.
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is [tex]\frac{x}{3} + 8 = -2[/tex]
Solving the equation using Natasha's method
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30
Second method of solving the equation
The equation the friends are trying to solve is [tex]\frac{x}{3} + 8 = -2[/tex]
The first step is to combine similar terms
[tex]\frac{x}{3}[/tex] = - 8 - 2
The second step is to add similar terms together
[tex]\frac{x}{3}[/tex] = - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

For the standard normal distribution, the area between z = 0 and z = 1.70, rounded to four decimal places, is:
Using normal distribution table, the area between z=0 and z=1.70 is the difference between p(z=0) and p(z=1.70). Hence, the area between z=0 and z = 1.70 is 0.4554
Using a normal distribution table :
P(Z < 0) = 0.5 P(Z < 1.70) = 0.95543The Area between z=0 and z= 1.70 is defined as the difference between the probabilities of (z < 1.70) and (z < 0)
P(Z < 1.70) - P(Z < 0) = 0.95543 - 0.5 = 0.45543
Therefore, the area between z = 0 and z = 1.70 rounded to four decimal places is 0.4554

look at the time for example, B's time is constant because it isn't skipping numbers like 1, 5, 3,etc.
the height is also constant because it is dividing each number by 2, 60÷2=30, 30÷2=15, 15÷2=7.5. You will notice A is not constant so (no) but B is so (yes)

Which point is an x-intercept of the quadratic function
f(x) = (x – 3)(x + 2)?
A(3, 0)
B(0, 2)
C(0, -2)
D(-3, 0)
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form [tex]f(x)=(x-h)(x-k)[/tex], where h and k are real numbers, the roots are [tex](h, 0)[/tex] and [tex](k, 0)[/tex].
Our parabola has a plus, though. That's a problem, right?
No! [tex]x+2=x-(-2)[/tex], so there's no problem. So, our roots are [tex](3, 0)[/tex] and [tex](-2, 0)[/tex].
So, the answer is A and we're done!

In an auditorium, a charity show is conducted in order to raise at least $3,000. The auditorium can
accommodate up to 180 spectators. Tickets cost $12 for students and $20 for adults. Identify the system of
inequalities and the corresponding graph that determine whether the charity will reach its goal.
If the number of adults is more than or equal to 105, then the goal is achieved otherwise not achieved.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
In an auditorium, a charity show is conducted in order to raise at least $3,000.
The auditorium can accommodate up to 180 spectators.
Tickets cost $12 for students and $20 for adults.
Let x be the number of students and y be the number of adults. Then we have
x + y = 180
12x + 20y ≥ 3000
By solving, equations 1 and 2. Then we have
x = 75 and y = 105
If the number of adults is more than or equal to 105, then the goal is achieved otherwise not achieved.

Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%. What was the cost of the sweatshirt before tax?
Answer:$25.00
Step-by-step explanation:
Net Amount (excluding tax) $25.00
Tax (10.0%) $2.50
Gross Amount (including tax) $27.50
in short 10% tax of $25.00 is $27.50.
The required cost of the sweatshirt before tax s given as $24.50.
What is the percentage?The percentage is the ratio of the compositions of matter to the overall composition of matter multiplied by 100.
Here,
Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%.
Cost of the sweatshirt before tax = 27.50 - 10% of 27.50
= 27.50 - 0.1× 27.50
= $24.50
Thus, the required cost of the sweatshirt before tax s given as $24.50.

Can someone help me please ?
Answer:
12 and (-12)
Step-by-step explanation:
Solve for x.
x^2= 144
square root both sides and get,
x= 12
and
x= (-12)
remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.
Answer:
x = 12
x = -12
Step-by-step explanation:
Step 1: Take the square root of both sides.
[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]Therefore, x = 12 and x = -12 are the answers.
