Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
So we have the equation:
[tex]5+(x-2)=-8[/tex]
Let's subtract 5 from both sides:
[tex](5+(x-2))-5=(-8)-5[/tex]
The left side will cancel. Subtract on the right:
[tex]x-2=-13[/tex]
Now, add 2 to both sides:
[tex](x-2)+2=(-13)+2[/tex]
Again, the left side will cancel. Add the right:
[tex]x=-11[/tex]
And we're done!
Answer:

Answer:
I do not sorry
Answer:
2 • (x - 6) • (3x + 2)
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
STEP 1 : Equation at the end of step 1
((2•3x2) - 32x) - 24
STEP 2 : Pulling out like terms
Pull out like factors :
6x2 - 32x - 24 = 2 • (3x2 - 16x - 12)
Trying to factor by splitting the middle term
Factoring 3x2 - 16x - 12
The first term is, 3x2 its coefficient is 3 .
The middle term is, -16x its coefficient is -16 .
The last term, "the constant", is -12
Step-1 : Multiply the coefficient of the first term by the constant 3 • -12 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .
-36 + 1 = -35
-18 + 2 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2
3x2 - 18x + 2x - 12
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x-6)
Add up the last 2 terms, pulling out common factors :
2 • (x-6)
Step-5 : Add up the four terms of step 4 :
(3x+2) • (x-6)
Which is the desired factorization
Final result : 2 • (x - 6) • (3x + 2)

Answer:-58
Step-by-step explanation:
round 9.69 to the nearest whole number
Rounding 9.69 to the nearest whole number gives us 10.
Given that we need to round the decimal number 9.69 to the nearest whole number,
To round 9.69 to the nearest whole number, we look at the decimal part of the number, which is 0.69.
Since the decimal part is greater than or equal to 0.5, we round the whole number up to the next higher number. In this case, 9.69 is closer to 10 than to 9, so we round it up to 10.
Therefore, rounding 9.69 to the nearest whole number gives us 10.

Which is a valid proportion?
pqrs is a rectangle with sides ps=5cm and pq =12cm find the length of qr ,sr and the two diagonals pr and qs.
tell the answer
PQRS is a rectangle.
PS = 5cm
PQ = 12cm
To Find:The length of qr ,sr and the two diagonals pr and qs.
Solution:Opposite sides of a rectangle are equal.
QR = PS = 5cm
SR = PQ = 12cm
By using Pythagoras Theorem, we get
PR = √PS^2 + SR^2
or, PR = √25 + 144
or, PR = √169
or, PR = 13cm
Diagonals of a rectangle are equal.
QS = PR = 13cm

How do you figure this equation out?
4r + 7 = 35
Answer:
r = 7
Step-by-step explanation:
Step 1: Write out equation
4r + 7 = 35
Step 2: Subtract 7 on both sides
4r + 7 - 7 = 35 - 7
4r = 28
Step 3: Divide both sides by 4
4r/4 = 28/4
r = 7
Solve 4r+7=35
4r=35-7
4r=28
r=7

Which inequality is shown in the graph?
Please help me the question is on the file ;-;
Answer:
D) 3x + 15 ≥ 300
Step-by-step explanation:
The rectangle must have a area of AT LEAST 300 square ft, or 300 or greater. Use the greater than or equal sign: ≥ 300.
Note that your are solving for the area, and that this shape is a rectangle. To get the area of the rectangle, simply multiply length and width:
(3) * (x + 5) = Area of rectangle.
Distribute the 3 to all terms:
3(x + 5) = 3x + 15 = Area of rectangle.
Put the two parts together:
3x + 15 ≥ 300.
~
Answer:
The last answer.
Step-by-step explanation:
The area of a rectangle is
Area=(width)*(length)
If we substitute the 2 given values into the formula we will get
Area= 3(x+5)
=3x+15
Since it's asking that it has to be "at least 300", it's saying that the equation has to be 300 or more.
3x+15>(less than or equal to) 300.
Which of the following equations has a graph with a y-intercept of -8?
Ay=3x - 8
B. y = -8x + 3
C. 3x - 8y = -5
D. -8x + 3y = -5
The equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8
To determine which of the given equations has a graph with a y-intercept of -8.
We will compare the equations with the slope-intercept form of the equation of a straight line.
The slope-intercept form of the equation of a straight line is
y = mx + c
Where m is the gradient or slope
and c is the y-intercept
For A. y =3x - 8By comparing with y = mx + c
m = 3 and c = -8
∴ The y-intercept here is -8
For B. y = -8x + 3By comparing with y = mx + c
m = -8 and c = 3
∴ The y-intercept here is 3
For C. 3x - 8y = -5This can be written as
y = (3/8)x + 5/8
By comparing with y = mx + c
m = 3/8 and c = 5/8
∴ The y-intercept here is 5/8
D. -8x + 3y = -5This can be written as
y = (8/3)x - 5/3
By comparing with y = mx + c
m = 8/3 and c = - 5/3
∴ The y-intercept here is -5/3
Hence, the equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8

If the translation of (x,y)->(x-5, y+2) was applied to the triangle ABC below, what would be the coordinates for A' after the translation?
Answer:
(-3,0)
Step-by-step explanation:
When translating, anything positive when talking about x would move x to the right. Negative, left, so you would move point a 3 units to the left.
When translating, anything positive when talking about y would move y up. Negative, down, so you would move point a 2 units up.

One car alarm is set to go off every ten seconds. Another car alarm is set to go off every 5 seconds, and a third car alarm is set to go off every 4 seconds. If they all go off at the same time due to a loud clap of thunder, how long will it take until they all sound at the same time again?
Answer:
20 seconds
Step-by-step explanation:
Alarm 1 = every 10 seconds
Alarm 2 = every 5 seconds
Alarm 3 = every 4 seconds
If they all go off at the same time due to a loud clap of thunder, how long will it take until they all sound at the same time again?
To determine how long it will take until they all sound at the same time again, find the lowest common multiple of the three alarm
Alarm 1 (every 10 seconds) = 20, 30, 40, 50, 60, 70, 80, 90,
Alarm 2 (every 5 seconds) = 10, 15, 20, 25, 30, 35, 40, 45, 50
Alarm 3 (every 4 seconds) = 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
The lowest common multiple of Alarm 1 (every 10 seconds), Alarm 2 (every 5 seconds) and Alarm 3 (every 4 seconds) is 20 seconds
Therefore, they will all sound at the same time again in the next 20 seconds
