[tex]\large\boxed{\tt\:Question}[/tex]
x² - 8x + 12 = 0
Hello meremyj! Here's your answer with explanation.
[tex]\large\boxed{\tt\:Answer\:with\:Explanation}[/tex]
[tex]x ^ { 2 } - 8 x + 12[/tex]
Use the biquadratic formula =》 [tex]x=\frac{-b±\sqrt{\left(-b\right)^{2}-4 ac}}{2}[/tex]
Now,
b = 8 c = 12 a = 1Using the biquadratic formula & substituting the values....
[tex]x=\frac{-\left(-8\right)±\sqrt{\left(-8\right)^{2}-4\times 12}}{2} \\x=\frac{-\left(-8\right)±\sqrt{64-4\times 12}}{2} \\x=\frac{-\left(-8\right)±\sqrt{64-48}}{2} \\x=\frac{-\left(-8\right)±\sqrt{16}}{2} \\x=\frac{-\left(-8\right)±4}{2} \\\underline{\underline{x=\frac{8±4}{2}} }[/tex]
Now, solve when [tex]x=\frac{8+4}{2}[/tex]
[tex]x=\frac{8+4}{2}\\x=\frac{12}{2} \\\boxed{\bf\:x=6 }[/tex]
Now, solve when [tex]x = \frac{8-4}{2}[/tex]
[tex]x = \frac{8-4}{2}\\x = \frac{4}{2}\\\boxed{\bf\:x=2}[/tex]

a. For y = 5+ 80 when x = 4, what does y equal?
b. For a = 3 - 5c when c = -0.5, what does a equal?
c. For n = 2d2 – 5 when d = -2, what does n equal?
n
d. For v = -3(1 – 3) when r = -1, what does v equal?
a. y = 5x + 80 = 5*4 + 80 = 20 + 80 = 100
b. a = 3-5c = 3 - 5*(-0.5) = 3 - (-2.5) = 3 + 2.5 + 5.5
c. n = 2d² - 5 = 2*(-2)² - 5 = 2* 4 - 5 = 8 - 5 = 3
d. v = -3(1-3r) = -3(1-3(-1)) = -3(1+3) = -3*4=-12

y = -2x - 4
--> Swap sides so that all variable terms are on the left hand side
-2x - 4 = y
--> Add 4 to both sides
-2x = y + 4
--> Divide both sides by -2
-2x/-2 = y+4/-2
--> Dividing by -2 undoes the multiplication by -2.
x = y+4/-2
--> Divide y+4 by -2
x = -y /2 -2
-------------------------------------------------------------
y = 1/4x + 5
--> Swap sides so that all variable terms are on the left hand side.
1/4x + 5 = y
--> Subtract 5 from both sides.
1/4x = y - 5
--> Multiply both sides by 4.
1/4x 1/4 = y - 5/ 1/4
--> Dividing by 1/4 undoes the multiplication by 1/4.
x = y - 5/ 1/4
--> Divide y - 5 by 1/4 by multiplying y - 5 by the reciprocal of 1/4.
x = 4y - 20

what is the value of a in a/5 + 3= 8
Answer:
Step-by-step explanation:
what is the value of a in a/5 + 3= 8
a/5 + 3= 8
a/5 = 8 - 3
a/5 = 5
a = 5 * 5
a = 25
Answer: a= 25
Step-by-step explanation:
first, you'll have to write the opposite of the + symbol which is - and then you'll have to lose the 3 by substracting it with, so the equation will look like this: a/5= 8-3 not 8+3
a/5=5
after that step you'll have to multiply 5 from the equal sgin with the 5 that is divided by a, so the final equation looks like this:
a=5x5
a=25
now let's make a verification:
25/5+3=8
5+3=8
a=25

Find the perimeter.simplify your answer.
The perimeter of a shape is the sum of its side lengths.
The perimeter of the shape is 24z - 18
Represent the length with l and the width with w.
The dimensions are given as:
[tex]l = 10z[/tex]
[tex]w = 2z - 9[/tex]
So, we have:
[tex]P =2 \times (l + w)[/tex] --- the formula of perimeter
The above equation becomes
[tex]P = 2 \times (10z + 2z - 9)[/tex]
Evaluate like terms
[tex]P = 2 \times (12z - 9)[/tex]
Open brackets
[tex]P = 24z - 18[/tex]
Hence, the perimeter of the shape is 24z - 18

is the opposite of Owen's and is a
positive value, what is David's score?
Answer:
aaa is easy you can pitch the ball
Owen's score will be (-6) and David's score will be opposite to that of Owen's score and a positive value, which will be (+6).
What is absolute value of a number?The absolute value of a number is the magnitude of number. Absolute value describes the distance from zero that a number is on the number line, without considering direction.
We have Owen's score in a card game is 6 points away from zero. David's score is the opposite of Owen's and is a positive value.
For a number [x], such that [x] < 0, the absolute value would be -
v[a] = -x
A number cannot be negative and positive at the same time, therefore, Owens score is 6 points away from 0, but in the negative direction of number line. So, Owen's score will be (-6) and David's score will be opposite to that of Owen's score and a positive value, which will be (+6).
Therefore, Owen's score will be (-6) and David's score will be opposite to that of Owen's score and a positive value, which will be (+6).

Answer:
f(x) = 3x +4f(x) = 5x +2f(x) = -4x +11f(x) = -4x +11 (same table as problem 3)Step-by-step explanation:
To write the equation for f(x) in slope-intercept form, you need to know the slope and the y-intercept. The y-intercept is the value of f(x) when x=0. You can read this directly from the table.
The slope is the ratio of the change in f(x) to the change in x. It can be computed using the formula ...
m = (y2 -y2)/(x2 -x1)
where (x1, y1) and (x2, y2) are any two pairs of numbers from the table. You can use the first two table rows, for example.
__
1. m = (10 -4)/(3 -0) = 6/3 = 2; y-intercept = 4 (from ordered pair (0, 4))
y = mx +b . . . . line with slope m and y-intercept b
f(x) = 2x +4
__
2. m = (2 -(-3))/(0 -(-1)) = 5/1 = 5
f(x) = 5x +2
__
3. m = (11 -19)/(0 -(-2)) = -8/2 = -4
f(x) = -4x +11

From the given figure, we can infer that ~

now, let's solve for x ~
[tex]5x - 20 \degree = 180 \degree[/tex][tex]5x = 180 \degree + 20 \degree[/tex][tex]5x = 200 \degree[/tex][tex]x = 200 \degree \div 5[/tex][tex]x = 40 \degree[/tex]And, we can see that 2x = y (by alternate interior angle pair)

x = 40
3x - 20 = 100
2x = 80
y = 80
2x - 15 = 65
Step-by-step explanation:
The angles 3x - 20 and 2x are a linear pair, so they are supplementary. Their measures has a sum of 180°.
Angles 2x and y are alternate interior angles, so they are congruent.
Once we find the value of x, we can find the measure of angle 2x - 15.
3x - 20 + 2x = 180
5x = 200
x = 40
3x - 20 = 3(40) - 20 = 120 - 20 = 100
2x = 2(40) = 80
y = x = 80
2x - 15 = 2(40) - 15 = 80 - 15 = 65
