Answer:
The simplified expression is
2x2+7x−13.
Step-by-step explanation:
Explanation:
Since this isn’t an equation, but rather an expression, it can only be simplified, not evaluated.
So let’s simplify it.
First distribute the
t (x2−1)
⇒3x2−3−(x2−7x+10)
Distribute the negative sign and drop the parentheses
:⇒3x2−3−x2+7x−10
Combine like terms:
⇒2x2+7x−13

Answer: The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees
Step-by-step explanation:
The error is the number of sides, it should be 9 sides and not 25.
Polygon sum of interior angles formula: 180 x (n-2)
So here n = 9 (sides)
180 x (9-2)
180 x 7 = 1 260 degrees
Answer:
sum of interior angles = 180 * n - 2
n = number of sides
in this case, the shape has 9 sides so n = 9
so the correct answer should be
= 180 * (9-2)
= 180 * 7
= 1260

What is the distance, in units, between the y-intercept of f(x) = x2 + 7x - 18 and the y-intercept of the linear function that passes through

-5
2

11

Answer:
y = 0.6x - 5
Step-by-step explanation:
The distance between the y-intercept of f(x) = x^2 + 7x - 18 and the y-intercept of the table is 23 units
How to determine the distance?The function f(x) is given as:
f(x) = x^2 + 7x - 18
The y-intercept is when x = 0.
So, we have:
f(0) = 0^2 + 7(0) - 18
Evaluate
f(0) = -18
For the table, start by calculating the slope (m)
m = 11 - 2/10 + 5
m = 0.6
The y-intercept is then calculated using:
b = y - mx
So, we have:
b = 11 - 0.6 * 10
Evaluate
b = 5
This means that:
y-intercept = 5
The difference between both values is:
Difference = |-18- 5|
Evaluate
Difference = 23
Hence, the distance between the y-intercept of f(x) = x^2 + 7x - 18 and the y-intercept of the table is 23 units

Write the nth term of the following sequence in terms of the first term of the sequence.

Answer:
[tex]\bold{a_n=2\cdot(-2)^{n-1}}\\\\or\\\\\bold{a_n=(-1)^{n-1}\cdot2^{n}}[/tex]Step-by-step explanation:
-4÷2 = -2
8÷(-4) = -2
-16÷8 = -2
So this is a geometric sequence with the first term of 2 and a common ratio of -2
the nth term of a geometric sequence: [tex]a_n=a_1\cdot r^{n-1}[/tex]

Noah was asked to find the median of the following numbers.
115, 109, 117, 136, 127, 131
Noah’s work is shown below.
109, 115, 117, 127, 131, 136
StartFraction 117 + 127 Over 2 EndFraction = StartFraction 244 Over 2 EndFraction = 122
What error, if any, did Noah make?
He forgot to put the numbers in order first.
He crossed off the high/low number pairs incorrectly.
He left out a number when putting the numbers in order.
He did not make any error.
Answer:
No error
Step-by-step explanation:
Nothing to explain
Answer:
Noah did not make any errors
Step-by-step explanation:
The median is a list of strictly increasing numbers is simply the middle number. if there's an even number of numbers in the list, then the median is the average of the middle terms.
here, the numbers are 115, 109, 117, 136, 127, 131. when ordered from least to greatest we get 109, 115, 117, 127, 131, 136 which is what Noah got.
since there are 6 numbers (6 is even), the median will be the average of the middle two numbers which are 117 and 127: (117+127)/2=244/2=122
so Noah is was correct.
A drawing of a triangle. The base equals 15 centimeters and height equals 8 centimeters.
Answer:
17
Step-by-step explanation:
If we are finding the long angled side (the hypotenuse), we must keep in mind the Pythagorean theorem. This states that in order to find the answer, we must follow: A squared + B squared = C squared. A and B are known as the legs and we use these for A and B. After squaring both 15 and 8 we get 225 + 64= 289. Now that we have our answer of 289, we can square this to find our hypotenuse which is 17. To find the square root, you multiply different numbers by themselves until you reach your answer. 17 x 17 = 289 so the hypotenuse is 17 centimeters long. I hope this helps! :)
