Which expression is a perfect square?
A. x² - 4x + 4
B. x2 - 4x - 4
C. 12 - 9x + 9
D. 12 - 9x – 9
Answer: Choice A
========================================================
Explanation:
A perfect square trinomial is of the form
(m+n)^2 = m^2 + 2mn + n^2
We can see why this works through use of the FOIL rule.
So the first and last terms must be perfect squares, and they must be positive. This rules out choices B and D since we have -4 and -9 as those last terms being negative.
Choice C is ruled out because the middle coefficient -9 isn't correct. The middle coefficient must be some even number since 2 is a factor of 2mn.
This leaves choice A. We can do a bit of trial and error to find that
(x-2)^2 = x^2 - 4x + 4
showing that choice A is a perfect square trinomial.
Answer:
A) x² - 4x + 4
Step-by-step explanation:
Given the following special factoring formulas on perfect square trinomials:
u² + 2uv + v² = (u + v)²
u² - 2uv + v² = (u - v)²
Apply these concepts on the given set of equations to see which special factoring formulas apply on the given options. I will only work on one of the given options, and you could apply these same techniques on the other ones to compare the results with your calculations.
To find the binomial factors of quadratic equations, you must find factors with product uv, and sum v.
In Option A: x² - 4x + 4
Right off the bat, it seems like the difference of squares may apply to this equation. You must find the factors that will product of 4 and a sum of -4.
The possible factors are:
product uv: -2 × -2 = 4,
sum v : -2 + -2 = -4
Hence, the binomial factor of x² - 4x + 4 = (x - 2)²
If you expand this binomial through FOIL method:
(x - 2)(x - 2) = x² - 2x - 2x + 4 = x² - 4x + 4
This means that the trinomial x² - 4x + 4 produces a perfect square binomial factors of (x - 2)².
Therefore, the correct answer is Option A) x² - 4x + 4.

38=1/8k+47
Find the value of k
Answer:
[tex]k=-72[/tex]
Step-by-step explanation:
[tex]38=\frac{1}{8} k+47[/tex]
Switching the sides of the equation isn't required, but it helps to reduce confusion.
[tex]\frac{1}{8}k+47=38[/tex]
Since there is a positive 7, we are going to do the opposite operation, which is addition.
[tex]\frac{1}{8}k+47-47=38\\\text\:\:\:\:\:\:-47\:\:\:\:\:\:\:\:\:-47[/tex]
Simplify
+47 - 47 will cancel each other out, so we are left with:
[tex]\frac{1}{8}k=-9[/tex]
Now, multiply 8 to both sides, since the equation gives us 1 divided 8, so the opposite operation of division is multiplication.
[tex]8\cdot \frac{1}{8}k=8\left(-9\right)[/tex]
On the right side, we have the same thing as [tex]\frac{8}{1} \cdot \frac{1}{8}[/tex], so 8 we can cancel the equation on the right side since they are both the same number.
On the left, we have [tex]8\left(-9\right)[/tex], which is -72.
Therefore, [tex]k=-72[/tex].

The function g(x) is a transformation of the quadratic parent function, f(x)=x2. What function is g(x)?
Answer:
D.
Step-by-step explanation:
Your graph of f(x)= [tex]x^2[/tex] is the parent function. What you need to know for this graph what the stretch or compression is and what the flip is. When you flip somehting over the x-axis, which is g(x), your [tex]x^2[/tex] is negative. Also, since your graph gets skinnier, the number before the x would be a whole number, with no fractions. The only answer that fulfills this is answer choice D.

Matthew is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 2 points. What would be Matthew's test score (out of 40) if he got 9 questions wrong? What would be his score if he got xx questions wrong?
Answer:
22 points
Step-by-step explanation:
If their are fourty points avaliable and each question is worth two points, then there are a total of twenty questions (20 times 2 is 40). Therefore, if he gets nine questions wrong, he would have gotten 11 right. Because we know that each question is two points, we may just multiply 11 by 2, which means he has gotten a score of 22 points!

Jonny is writing a program for a video game.
For one part of the game he uses the
rule given below to move objects on the screen.
Showing all your work, give the output that the rule gives for the inputs.
(x, y) + (2 – 7.5, y + 6.8)
First input: (4.4.2.5)
Second input: (9.7, -2.9)
Answer:
.
Step-by-step explanation:
Answer:
(-3.2 , 12.3)
(0.7 , 3.6)
Step-by-step explanation:
The rule :
(x, y)→(x−7.5, y+6.8)
For the x - coordinate ; Subtract 7.5
For the y - coordinate `; add 6.8
First input : (4.3, 5.5)
Output :
x = 4.3 - 7.5 = - 3.2
y = 5.5 + 6.8 = 12.3
Output = (4.3, 5.5) →(-3.2 , 12.3)
Second input : (8.2, -3.2)
Output :
x = 8.2 - 7.5 = 0.7
y = - 3.2 + 6.8 = 3.6
Output = (8.2, -3.2)→(0.7 , 3.6)
The outputs obtained are :
(-3.2 , 12.3) and (0.7 , 3.6)
A line passes through the points (-6, 8) and ( 3, 7). What is the equation of the line in Slope-Intercept Form?
Step-by-step explanation:
y=−x+2
Explanation:
Alright, so this is a two-part question. First we need to find the slope, then we need to find the y-intercept. Finally we plug all this into the slope intercept equation y=mx+b
The slope is commonly referred to as m=riserun this can also be expressed as m=y2−y1x2−x1 by using the change in y and the change in x.
m=5−8−3−(−6)
m=−33
m=−1
Alright, now lets find the y-intercept by using that slope. If we plug that slope into the base formula we get y=−x+b. Since we already know one point, lets put (−3,5) into that equation and solve for b.
5=−(−3)+b
5−3=3+b−3
2=b
Now is if plug out b into out equation, we get a finally answer of y=−x+2
Even though we're done, lets check it by putting in the other point.
8=−(−6)+2
8−6=6+2−6
2=2
