Answer:
[tex]x=\frac{-1}{4} +/-\frac{1}{4}\sqrt{17}[/tex]
Step-by-step explanation:
First, we need to get the equation into the polynomial form. Add 8 to both sides:
[tex]-6x^{2} -2-3x=-8[/tex]
[tex]-6x^{2} +6-3x=0[/tex]
Rearrange the equation so that it is in standard form:
[tex]-6x^{2} -3x+6=0[/tex]
Remember the quadratic formula:
[tex]\frac{-b+/-\sqrt{b^{2}-4ac} }{2a}[/tex]
[tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are the coefficients of the problem when it is in standard form. In this case, [tex]a=-6[/tex], [tex]b=-3[/tex], and [tex]c=6[/tex]. Now, all we need to do is plug those into the quadratic formula.
[tex]\frac{-(-3)+/-\sqrt{(-3)^{2}-4(-6)(6)} }{2(-6)}[/tex]
Simplify:
[tex]\frac{3+/-\sqrt{153}}{-12}[/tex]
[tex]x=\frac{-1}{4} +/-\frac{1}{4}\sqrt{17}[/tex]
Hope this helps!
Which of the following is equivalent to (5x^2)(4x^3)
Answer:
20x^5
Step-by-step explanation:
You just multiply 5 by 4 and get 20 and when multiplying exponents you just add them together so you get 20x^5

Find the missing values.
Answer:
Below in bold.
Step-by-step explanation:
The 2 triangles are congruent and they are both isosceles.
So m < 3 = 54 degrees. (isosceles triangle)
m < 2 = 54 degrees. (congruent triangles)
m < 1 = 180 - 2(54)
= 180 - 108
= 72 degrees. (angles in a triangle sum to 180).
m < 4 = 72 degrees. (congruent triangles),
Is there a series of rigid transformations that could map TriangleKLP to TriangleQNM? If so, which transformations? No, TriangleKLP and TriangleQNM are congruent but TriangleKLP cannot be mapped to TriangleQNM using a series rigid transformations. No, TriangleKLP and TriangleQNM are not con gruent. Yes, TriangleKLP can be reflected across the line containing KP and then translated so that P is mapped to M. Yes, TriangleKLP can be rotated about P and then translated so that L is mapped to N.
Answer:
C. Yes, Triangle KLP can be reflected across the line containing KP and then translated so that P is mapped to M

is y=-2/5x inverse or direct variation
Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]
Is 11 a solution to 3(x+6)=4x ?
Answer:
The number 11 is not a solution for the given equation.
Step-by-step explanation:
We are given an equation with one variable. We can use simplifying processes to solve the equation.
[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]
We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.
[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]
Therefore, 11 is not a solution for the given equation.
Answer:
First of all,We need to find the value of x to find that 11 is the solution to 3(x+6)=4x or not.[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]
[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]
[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]
Let's put x as 11:[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]
[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]
[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]
51 doesn't equal to 44.So,11 is not the correct solution to 3(x+6)=4x.Melissa earned $17 for 2 hours walking her dogs. Last week sh walking dogs for 8 hours how much did she make last week
Answer:
she made $68 last week.
Answer:
$68
Step-by-step explanation:

31 = - (1 +6p ) +4(p + 6 )
Answer:
p = -4
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Answer:
p = -4
Step-by-step explanation:
I'm not going to explain each step, just try to follow along.
31 = -(1+6p)+4(p+6)
31 = -1-6p+4p+24
7 = -1-2p
8 = -2p
p = -4

Answer:
My answer is = 9 cannot equal 12. There are no variables present in this equation, so what are you solving for?
Step-by-step explanation:
On the right you would use distributive property and on the left you would just simply add and subtract.
However, you cannot equal it to zero either because there are no variables nor exponents.
Tim throws a stick straight up in the air from the ground. The function h = -16t^2+ 48t models the height, h, in feet, of
the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick
reaches a height of more than 8 feet?
Answer:
[tex]-2t^2+ 6t -1 > 0[/tex]
Step-by-step explanation:
Function Modeling
The height h in feet of the stick threw by Tim is modeled by the function:
[tex]h = -16t^2+ 48t[/tex]
where t is the time in seconds.
It's required to write an inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet, i.e. h > 8.
Using the given model, we write the inequality:
[tex]-16t^2+ 48t > 8[/tex]
Dividing by 8
[tex]-2t^2+ 6t > 1[/tex]
Subtracting 1, we get the required inequality:
[tex]\mathbf{-2t^2+ 6t -1 > 0}[/tex]
Answer:
you want more than 8 feet so the answer would be -16t^2+48t>8
Step-by-step explanation:
h=-16t^2+48t
-16t62+48t>8
-16t^2+48t=8
divide both sides of the equal sighn by 8
-2t^2+6t=1
put the symbol back in
-2t^2+6t>1
substitute a random mumber for t
-2(5)^2+6(5)>1
-10^2+30>1
subtract 30 from both sides
100>-29
state is true so -16t62+48t>8 is the correct answer

Is this correct, i did 21.5 times 33.6 and converted it to yards to the nearest tenth and i got 80.3
Answer:
Thats what i got too :)
Step-by-step explanation:
You have the correct answer. It is 80.3 square yards.
Work Shown:
Area of parallelogram = length*width = 21.5*33.6 = 722.4 sq ft
1 yard = 3 ft
1 sq yd = 9 sq ft ... square both sides
To convert from square feet to square yards, we'll divide by 9
This is the same as multiplying by 1/9
722.4 sq ft = (722.4 sq ft)*(1 sq yd/9 sq ft)
722.4 sq ft = (722.4)*(1/9) sq yards
722.4 sq ft = 80.2667 sq yards
722.4 sq ft = 80.3 sq yards
