Step-by-step explanation:
f(x) = x² + 2ax + a² - a
g(x) = 4 - x²
Let variable a be a real number. Find the range of values of a such that the equation f(x) = g(x) has two different solutions.
***The answer should be -2 < a < 4, but I don't know why.
Answers
Step-by-step explanation:
f(x) = x² + 2ax + a² - a
g(x) = 4 - x²
f(x) = g(x)
x² + 2ax + a² - a = 4 - x²
2x²+2ax+a²-a -4 =0
the equation has two different solutions
=> (2a)² - 4(2)(a²-a-4) > 0
4a²-8a²+8a +32 >0
-4a²+8a+32 > 0
a²-2a-8 >0
(a-4)(a+2) < 0
the answer should be
-2 < a < 4
Is this correct now?

6. What is the value of x in the solution to the systems of linear equations shown below?
2x - 2y+z=3
5y-z= -31
x+ 3y + 2z = -21
Answers
Step-by-step explanation:
[tex]1) \: \: 2x - 2y + z = 3 \\ 2x = 3 + 2y - z \\ x = \frac{3 + 2y - z}{2} \\ \\ 2) \: \: \: not \: any \: \: \: x \: \: \: available \: \: \\ \\ 3) \: \: x + 3y + 2z = - 21 \\ x = - 21 - 3y - 2z[/tex]
Answer:
x= -5
Step-by-step explanation:
5y-z= -31, add z and 31 to both sides
5y+31 = z, substitute z in the other two given equations
2x - 2y+z=3
2x-2y +5y+31 = 3, combine like terms and subtract 31 from both sides
2x+3y = -28
x+ 3y + 2z = -21
x+3y +2(5y+31) = -21, distribute 2 over the addition parenthesis
x+3y +10y+62 = -21, combine like terms and subtract 62 from both sides
x+13y = -83
Now we have 2 equations with 2 variables x and y to solve
2x+3y = -28
x+13y = -83
Because we need to find x then from the first equation we can write that
3y = -2x-28, subtract 2x from both sides and the divide both sides by 3
y = (-2x-28)/3, substitute this in the second equation
x + [13(-2x-28)/3] = -83 , distribute 13 . over the subtraction parenthesis
(3x/3)+[(-26x - 364) /3= -83, find the common denominator
3x+[(-26x - 364) = -83*3 , cross multiply
3x -26x = -249 +364, add 364 to both sides
- 23x = 115, divide both sides by (-23)
x= -5

explanation:
if we turn the first option into an improper fraction: we get 1 3/4, so it’s not the first answer. for the second answer choice, we can convert 3/4 into the 8ths by multiplying both parts of the fraction by 2 to get 6/8. Since 7/8 is greater than 6/8, it’s not the second choice either. Knowing that 3/4 is the same as 6/8, 5/8 is less then 6/8 because 5 is less than 6. So, 5/8 is between 3/4 and 1. hope this helped!!
Answer:
5 / 8
Step-by-step explanation:
3 / 4 = 0.75
5 / 8 = 0.625
5 / 8 is between 1 and 3 / 4.
Write the equation in standard form.
y+ 7= -3/2 (x+1)
Answers
Answer:
2y + 3x = -17
Step-by-step explanation:
standard form is Ax + By = C
first step is to distribute -3/2 among 'x' and then by 1 to get:
-3/2x - 3/2
you now have y + 7 = -3/2x - 3/2
we want to get the -3/2x term on the same side as 'y' and get 7 from the right side to the left side
we want to add 3/2x to the left side of the equation because it is being subtracted:
y + 3.2x + 7 = -3/2
now we want to subtract 7 to the right side because it is currently being added:
y + 3/2x = -7 3/2
we can convert -7 3/2 to be -17/2
we now can eliminate the denominator of 2 in the 'x' term by multiplying each term by 2 to get:
2(y + 3/2x) = -17/2(2)
distribute and simplify to get:
2y + 3x = -17
Prove the polynomial identity.
(4x^2−2)^2−(4x^2)^2=4(1−2x)(1+2x)
Drag and drop the lines of the proof in the correct order to complete the proof.
Answers
Answer:
(4x^2 - 2)^2 - (4x^2)^2 = 4(1 - 2x)(1 + 2x)
16x^4 - 16x^2 + 4 - 16x^4 = 4(1 - 2x)(1 + 2x)
4 - 16x^2 = 4(1 - 2x)(1 + 2x)
4(1 - 4x^2) = 4(1 - 2x)(1 + 2x)
4(1 - 2x^2)(1 + 2x) = 4(1 - 2x)(1 + 2x)

Answer:
Step-by-step explanation:
We can use the point-slope formula to write an equation for this line. The point-slope formula states :
where m is the slope and (x1 y1) is a point the line passes through .
We can substitute the slope and values from the point to give:
(y-1) = 8 (x-7)
We can also transform this equation to the slope-intercept form by solving for
y
. The slope-intercept form of a linear equation is: y=mx+b
where the m is the slope and b s the y-intercept value.
y-1= (8 times x) - ( 8 times 7)
y-1= 8x - 56
y-1 + 1= 8x- 56 + 1
y-0= 8x- 55
y= 8x - 55

a. y = -2x-5
Step-by-step explanation:
*Don't get confused the y-axis scale is 2
I guess you would kind of have to guess by looking at the graph for this one, the y-intercept is 5.
The graph is negative because it is pointing the opposite way
The slope is 2 because the y-axis has a scale of 2
With these facts you can formulate that the equation would be y = -2x-5

Answers
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The equation is given in "slope-intercept" form.
y = mx + b
where m is the slope, and b is the y-intercept.
__
For graphing, it is usually convenient to start with the y-intercept. The value of 'b' in your equation is +1, so the graph will go through the point y=1 on the y-axis. That point's coordinates are (0, 1).
The value of m represents the slope, or "rise"/"run" of the line. A slope of -2/3 means the line "rises" -2 units for each "run" of 3 units to the right. Then another point on the graph will be 3 units to the right of the y-axis, and 2 units down from y = 1. That point is (3, -1).
The line is drawn through these points you found on the graph.

30x + 5 = 9x subtract 9x on both sides
21x+5 = 0 subtract 5 on both sides
21x = -5 divide 21 on both sides
