If M is the midpoint of AB, A(-3, 4) and M(-1, 2) find the coordinates
of B.
Answer:
B(1,0)
Step-by-step explanation:
The midpoint of (a,b) and (c,d) is ((a+c)/2,(c+d)/2)
Essentially, you just average the x and y values.
So, the average of -3 and b_x is -1.
The average of 4 and b_y is 2.
So x=1 and y=0

evaluate the expression x+4x-3+3x^2-2x when x = 5
Given:
The expression is
[tex]x+4x-3+3x^2-2x[/tex]
To find:
The value of given expression when x=5.
Solution:
We have,
[tex]x+4x-3+3x^2-2x[/tex]
Substituting x=5 in the above expression, we get
[tex]=(5)+4(5)-3+3(5)^2-2(5)[/tex]
[tex]=5+20-3+3(25)-10[/tex]
[tex]=5+20-3+75-10[/tex]
On further simplification, we get
[tex]=(5+20+75)+(-3-10)[/tex]
[tex]=100+(-13)[/tex]
[tex]=100-13[/tex]
[tex]=87[/tex]
Therefore, values of the given expression at x=5 is 87.
A police officer recorded the speeds of 100 cars in a 50-mile-per-hour zone. The results are in the box plot shown. How many cars were going between 40 and 48 miles per hour? I know the answer but I need to know how to do it
Answer: 25 cars
Step-by-step explanation:
This is a box plot and it is a useful graph for showing the minimum, maximum, median and quartile values of a data distribution.
The box you see in the middle is the Interquartile range. In other words, the first line on the box is Q1 and the line at the end of the box is Q3.
The line in the middle of the box is the median or Q2.
The distance between Q1 and the median is 25%.
The number of cars between 40 and 48 miles per hour is therefore 25% of the total.
= 100 * 25%
= 25 cars
Answer:
25 cars

1_____ × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also
2_____ times greater than 9.5 × 10-4.
Answer:
Well, 1 is 3.8 The second one is 40,
Step-by-step explanation:
I believe 1 is 3.8, b/c 1.9*2 is 3.8, and the difference between exponents makes 3 zeros, so 2000.
The second one is 40, I confirmed this by doing .0001 to replicate 10 to the negative 4th power
By doing 9.5*.0001*40, I got the 0.038 from 1
Answer:
3.8 × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also 4 times greater than 9.5 x 10-4.
Step-by-step explanation:
I started by doing 0.0000019 x 2000 and got 0.0038. If you move the decimal point 4 over you get 3.8.

If f(x) = 4x^3 + 5, then what is the remainder when f(x) is divided by x-3?
Answer:
4, 5 is the point and I don't think there is a remainder
Step-by-step explanation:
The remainder when f(x) = 4x³ + 5 is divided by x - 3 the remainder is 113.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, f(x) = 4x³ + 5 now dividing f(x) by x - 3 = 0 ⇒ x = 3 is the same as replacing x with 3 in f(x).
∴ f(3) = 4(3)³ + 5.
f(3) = 4(27) + 5.
f(3) = 108 + 5.
f(3) = 113.
So the remainder when f(x) = 4x³ + 5 is divided by x - 3 the remainder is 113.

Alexander invested $320 in an account paying an interest rate of 1.5% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 18 years?
Answer:
$406.40
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.5%/100 = 0.015 per year.
Solving our equation:
A = 320(1 + (0.015 × 18)) = 406.4
A = $406.40

The first lap of an auto race is 2,500 meters. This is 10% of the total race distance. What is the total race distance?
Answer:
25,000
Step-by-step explanation:
.10(x) = 2,500
X = 2,500/(.10)
X=25,000
The length of the total race track is 25000 meters.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Let, 'x' be the total distance.
Therefore, From the given information 10% x is 2500 meters, This can be numerically expressed as,
(10/100)×x = 2500.
0.1x = 2500.
x = 25000.

Answer:
x = 3(y -1)
Step-by-step explanation:
In this, and any, "solve for ..." situation, you want to first take a look at where the variable of interest is in the equation, and what has been done to it.
Here, x is on the right side (only). It has these operations done to it:
multiplied by 1/31 added to the productYou solve for x by undoing these operations, in reverse order. As always, with any equation, you do the same thing to both sides of the equation.
__
First, we will undo "add 1". We do that by adding the opposite of 1.
y -1 = 1/3x +1 -1 . . . . . -1 added (to both sides)
y -1 = 1/3x . . . . . . . . . simplify
To undo the "multiply by 1/3", we can multiply by the "multiplicative inverse" (reciprocal) of 1/3. That is, we want to multiply by 3.
3(y -1) = 3(1/3x) . . . . . multiply (both sides) by 3
3(y -1) = x . . . . . . . . . simplify
We can leave it like this.
x = 3(y -1)
Or, we can eliminate parentheses using the distributive property .
x = 3y -3
These are completely equivalent equations with x as the subject.
