Answer:
B
Step-by-step explanation:
Choose an x point. Then plug it in and see if you get the correct y.
For example, I chose an x point of -1. When x = -1, you can see that y = 4.
Plug it in to the equations, and you find that B is correct.
y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1
4 = 1 - (-2) + 1
4 = 1 + 2 + 1
4 = 4

Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

the average screen time for middle school students is 240 minutes per day. In 2020 students went into virtual learning and the average screen time is 70 percent longer. What is the total percent of screen time this year?
Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)

Use the Distributive Property to write an expression that is
equivalent to 4(y - 3).
Answer:
4y-12
Step-by-step explanation:
To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).
If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.
The equivalent value of the expression is A = 4y - 12
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 4 ( y - 3)
On simplifying the equation , we get
A = 4 ( y - 3 )
So , the left hand side of the equation is equated to the right hand side by the value of A = 4 ( y - 3 )
Opening the parenthesis on both sides , we get
A = 4 ( y - 3 )
Using the distributive property , we get
A = 4 ( y ) - 4 ( 3 )
On further simplification , we get
A = 4y - 12
Taking the common factor as 4 , we get
A = 4 ( y - 3 ) = 4y - 12
Therefore , the value of A = 4y - 12
Hence , the expression is A = 4y - 12

Determine whether the lines are parallel, perpendicular, or neither.
y = 3x - 2
-3x + y = 8
Answer:
they are parallels
Step-by-step explanation:
they have the same slope but different y intercepts so they are parallel
Answer:
Parallel
Step-by-step explanation:
First, you should put the second equation in slope-intercept form, it would be y=3x+8.
If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.

Simplify 5 - 4(x - 1) - 2(x + 1)
Answer:
-6x+7
Step-by-step explanation:
Start by multiplying (x-1) by -4 and (x+1) by -2.
Then you will have the equation 5-4x+4-2x-2
Next, just find your like-terms.
Your like-terms are 5,4,-2 and -4x, 2x
Then, for easier for calculation, just use the equation:
-4x-2x+5x+4-2
Your final answer should then be:
-6x+7

the sum of two and a number is less than five
Answer:
Please check the explanation.
Step-by-step explanation:
Given the English statement
''The sum of two and number is less than five''.
Let us breakdown the statement.
Let 'n' be the number. The sum of two and number = 2 + nWe know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
2 + n < 5Let us solve the algebraic expression.
[tex]2+n<5[/tex]
Subtract 2 from both sides
[tex]2+n-2<5-2[/tex]
Simplify
[tex]n<3[/tex]
Thus, the solution is:
[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]
