Test help pls What is the value of the expression ((9 - 5)^2 – 1) + 3?
A) -5
B) 1
C) 5
D) 18
Answers
Answer:
D
Step-by-step explanation:
Here is what I did to arrive at my answer:
((9 - 5)^2 – 1) + 3
Use PEMDAS for this:
First, calculate what is in the parenthesis
(9-5)
=4
and you are left with
4^2-1
Next is exponents...
4^2 = 4 · 4
=16 - 1
Now substract
=15
Then add
15 + 3 = 18
There you have it! The answer is D, 18.
I hope this helps :)

Finally I went back and found him huddled beneath a red

ground, his face buried in his arms, which were resting

He didn't answer, so I placed my hand on his forehead
and lifted his head. Limply, he fell backwards onto the

neck and the front of his shirt were stained in brilliant red.
"Doodle! Doodle!" I cried, shaking him, but there was no

his head thrown far back, making his vermillion neck
appear unusually long and slim. His little legs, bent

Answer:
m = -3/2
Step-by-step explanation:
Given the following points on the graph, (0, 9) and (2, 6):
Let (x₁, y₁) = (0, 9)
(x₂, y₂) = (2, 6)
Plug these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 9)/ (2 - 0)
m = -3/2
Therefore, the slope of the graph is -3/2. It has a negative value (hence, a negative slope) because the line is declining from the left side of the graph towards the right.

i just need this last question Milan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $49.96 and costs an additional $0.15 per mile driven. The second plan has an initial fee of $57.96 and costs an additional $0.13 per mile driven. How many miles would Milan need to drive for the two plans to cost the same?
Answers
Answer:
400 miles
Step-by-step explanation:
Let the total cost of a plan be $T and the number of miles driven be m.
First plan
T= 0.15m +49.96 -----(1)
Second plan
T= 0.13m +57.96 -----(2)
When the two plans cost the same, the value of T in the first plan is equal to that of the second plan.
Equating (1) and (2) together:
0.15m +49.96= 0.13m +57.96
0.15m -0.13m= 57.96 -49.96
0.02m= 8
m= 8 ÷0.02
m= 400
∴ Milan would need to drive 400 miles for the two plans to cost the same.

At a local garden shop, the price of plants includes sales tax. The cost of 4 large plants and 8 medium plants is $40. The cost of 5 large plants and 2 medium plants is $28. If l is the cost of a large plant and m is the cost of a medium plant, write a system of equations that models this situation.
Answers
Answer:
4L + 8 m = $40
5L + 2m = $28
Step-by-step explanation:
L = cost of a large plant
m = cost of a medium plant
4L + 8 m = $40
5L + 2m = $28
System of Equations : 8 M + 5 L = 40 ; 5 M + 2 L = 28
Given : Cost of 4 large plants 'L' & 8 medium plants 'M' = 40
Cost of 5 large plants 'L' & 2 medium plants 'M' = 28
So, as per total cost, the equations are :
8 M + 5 L = 40 5 M + 2 L = 28To learn more, refer https://brainly.com/question/23589883?referrer=searchResults

Rosa put an “blank” cream on the cut on her finger to keep germs out of it
1- interlocking

3-antiseptic
4- interrelated
Answers
Rosa put an antiseptic cream on the cut on her finger to keep germs out of it.
An antiseptic is a substance that prevents the growth and development of microorganisms, such as bacteria, on living tissues.
When Rosa applied antiseptic cream to her cut finger, she aimed to create an environment hostile to germs. This action helps prevent infections and promotes the healing process.
The term antiseptic is derived from the Greek words "anti," meaning against, and septikos, meaning putrefying. Antiseptics are commonly used for cleaning wounds, disinfecting surfaces, and maintaining personal hygiene. They are milder than disinfectants, which are typically used on inanimate objects.
Rosa's choice of an antiseptic cream demonstrates her understanding of the importance of wound care. The cream likely contained substances that inhibit bacterial growth, such as hydrogen peroxide or iodine. By applying the antiseptic cream, Rosa effectively created a barrier against potential infections. It's crucial to clean and treat cuts promptly, as untreated wounds can lead to more severe health issues.
In summary, the use of an antiseptic cream by Rosa showcases her responsible approach to wound care. Antiseptics play a vital role in preventing infections and supporting the body's natural healing process. By applying an antiseptic cream, Rosa took a proactive step in safeguarding her health and ensuring the well-being of her injured finger.

Suppose that you could replace the ordered pair (1, 4) to make the relation R (shown left) into a function. Which ordered pair would work? (1, 2) (â€"1, 4) (2, 3) (4, 15).
Answers
We want to see which ordered pair we can add to the one we have in order to make R a function (sadly, we do not have the relation R, so expect a general answer).
Let's start by defining a function.
A function is a relation that maps elements from one set, the domain, into elements of another set, the range.
Where we also have a rule, each element in the domain can be mapped into only one element in the range.
So for example, if our relationship is:
R { (1, 2), (1, 3), (2, 4)}
The element of the domain "1" is being mapped into two different elements of the range, then this is not a function.
So, to answer the question, you would want to replace the element (1, 4) from one element that does not share the first value with any other of the relation.
Just to given an example, if the relation is:
R : { (1, 1), (1, 4), (2, 3), (3, 6)}
From the options, the only one that does not share the first element with any of the ordered pairs in R is (4, 15)
Then we replace (1, 4) by (4, 15)
And the relation becomes:
R' : {(1, 1), (2, 3), (3, 6), (4, 15)}
Which is a function.

Answers
Answer:
y = (1/3)x - 7/2
Step-by-step explanation:
Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
Lets transform this equation into that form using algebra rules.
-2/3x +2y = -7
get y alone
2y = (2/3)x - 7
divide everything by 2
y = (2/6)x - 7/2
simplify
y = (1/3)x - 7/2
