[tex]f(x) = 2 {x}^{2} + 2x - 24 [/tex]
[tex]f(x) = 2( {x}^{2} + x - 12) [/tex]
[tex]0 = 2( {x}^{2} + x - 12)[/tex]
Divided sides by 2
[tex] {x}^{2} + x - 12 = 0 [/tex]
[tex](x + 4)(x - 3) = 0[/tex]
_________________________________
[tex]x + 4 = 0[/tex]
[tex]x = - 4[/tex]
_________________________________
[tex]x - 3 = 0[/tex]
[tex]x = 3[/tex]
Thus the actual roots are -4 and 3.....
And we're done.

Answer:
x= 3, -4
Step-by-step explanation:
Set 2 x ² + 2 x − 24 equal to 0 .
2 x ² + 2 x − 24 = 0
Solve for x .
Factor the left side of the equation.
2 ( x² + x − 12 ) = 0
Factor
x ² + x − 12 using the AC method.
2 ( x − 3 ) ( x + 4 ) = 0
If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0 .
x − 3 = 0
x + 4 = 0
Add 3 and subtract 4 to both sides of the equation.
x = 3
x = -4

Which equation can you create with the given information? m=6, b=-2 A.) y=6x-2 B.) y=6x+2 C.) y=2x+6 D.) y=-2x-6
Step-by-step explanation:
Hey there!
Your answer is Option A.
Check all:
A. y = 6x-2
Comparing the equation with y = mx+b, we get;
m= 6
and b= -2
B. y= 6x+2
Comparing the equation with y= mx+b, we get;
m = 6
b= 2
C. y = 2x+6
Comparing the equation with y= mx+b, we get;
m= 2
b = 6
D. y= -2x-6
Comparing the equation with y= mx+b, we get;
m= -2
b= -6
Therefore, Option A is correct answer.
Hope it helps...

PLEaSE ILL GIVE YOU BRAINLIEST AND 15 POINTS
Answer:
It's "P"
Step-by-step explanation: Please give me my 15 points
Answer:
X= 60º
Step-by-step explanation:
If you are solving for a ∆, a ∆ has a degree of 180º. This thus when added up gets you.
81º + 39º = 120º
180º - 120º = 60º
Therefore in conclusion, X would be 60º.
Your school district cancels school when more than 2.5 inches of snow accumulate on the ground each hour. Snow is currently accumulating at a rate of 115 inches per hour.

Is the inverse of the function shown below also a
function? Explain your answer.
Answer:
Yes it is
Step-by-step explanation:
It is a function because it passes the vertical line test
Answer:
If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that are also functions. Therefore, the inverse is a function.

Elise jarred 36 liters of jam after 6 days.How many days does Elise need to spend making jam if she wants to jar 48 litera of jam in all?Assume the relationship is directly proportional.
Answer:
The answer is 8 days.
Step-by-step explanation:
36 divided by 6 is 6. So we do 48 divided by 6 which is 8. Both 36 and 48 can be divided by 6.

Find the perimeter and area of the figure if each unit on the graph measures 1 centimeter. Round answers to the nearest tenth, if necessary. A(0,9) B(4,9) C(0, 1)
Answer:
Area = 16 cm²
Perimeter = 20.9 cm
Step-by-step explanation:
To find the perimeter and area of the given triangle length of all sides of the given triangle will be required.
Use the formula to determine the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between A(0,9) and B(4, 9),
AB = [tex]\sqrt{(4-0)^2+(9-9)^2}[/tex] = 4 cm
Distance between A(0,9) and C(0, 1),
AC = [tex]\sqrt{(0-0)^2+(9-1)^2}[/tex]
AC = 8 cm
Distance between B(4, 9) and C(0, 1),
BC = [tex]\sqrt{(4-0)^2+(9-1)^2}[/tex]
BC = [tex]\sqrt{16+64}[/tex]
= [tex]\sqrt{80}[/tex]
= [tex]4\sqrt{5}[/tex]
= 8.9 cm
Area of ΔABC = [tex]\frac{1}{2}(\text{AC})(\text{AB})[/tex]
= [tex]\frac{1}{2}(8)(4)[/tex]
= 16 cm²
Perimeter of the triangle = AB + AC + BC
= 4 + 8 + 8.9
= 20.9 cm

2(4+c)=67 help solve for c
Answer:
c = 29.5 or
c = 59/2
Step-by-step explanation:
2 (4 + c) = 67
8 + 2c = 67
8 - 8 + 2c = 67 - 8
2c = 59
c = 29.5
What’s 7 1/2 - 1 2/7
87/14 or 6 3/4. That's an improper fraction and then a mixed fraction. Same answer though
i can't figure it out
Answer:
see explanation
Step-by-step explanation:
Given
x - 6y = 18
To find the x- intercept let y = 0 in the equation and solve for x, that is
x - 0 = 18
x = 18 ← x- intercept ⇒ (18, 0 )
To find the y- intercept let x = 0 in the equation and solve for y, that is
0 - 6y = 18
- 6y = 18 ( divide both sides by - 3 )
y = - 3 ← y- intercept ⇒ (0, - 3 )
Solve the equation for x 6x-18-3x<27-2x

x<9
