Solve using the quadratic formula. Approximate answers to the nearest tenth.
Help
Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3
pls answer correct or i will ban you

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).
when
[tex] {x}^{3} + a {x}^{2} + 5x + 3[/tex]
is divided by
[tex]x + 2[/tex]
the remainder is b. Determine the value of b
x³ + ax² + 5x + 3. x + 2 = 0
x = -2
(-2)³ + a(-2)² + 5(-2) + 3 = 0
-8 + 4a - 10 + 3 = 0
4a - 15 = 0
4a = 15
a = 15/4
Given that a = two and b = 3, what is the value of (ab)?
Answer:
(ab) = 6
Step-by-step explanation:
a = 2 and b = 3
So, (2(3)) or 2 x 3 = 6

1) Find the distance between -49.75 and 31.5 on a number line.
Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25

Which graph shows the solution to the inequality (x+3/22?
Answer:
No 2
Step-by-step explanation:
what is the gradient for the table x y
-6 -10
-3 -8
3 -4
6 -2
Solution :
Let, equation of line is y = mx + c .
Here, m is the slope( or gradient ) of the line and c is the y-intercept .
Putting point ( -6, -10 ) in above equation, we get :
-10 = -6m + c ...1)
Also, putting point ( -3, -8 ) in above equation, we get :
-8 = -3m + c ...2)
Solving equation, 1) and 2) we get :
[tex]m = \dfrac{2}{3}\ and \ y = - 6[/tex]
Therefore, the gradient for the given x-y table is [tex]\dfrac{2}{3}[/tex] .
What is the slope of the line through the points (-2, -1) and (4, 3)?
Answer: [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Answer:
m=2/3
Step-by-step explanation:
Identify the coordinates (x₁,y₁) and (x₂,y₂) . ...
Input the values into the formula. (-2,-1) (4,3) the formula is (y1-y2)/(x1-x2)
Subtract the values in parentheses to get 4/6
Simplify the fraction to get the slope of 2/3
