Solve for x: −2(x + 3) = −2x − 6 NEED HELP PLZ:(A: 0
B: 3 C:All real numbers
D:No solution
Answers
Answer:
The answer is C:All real solutions
Step-by-step explanation:
here are the steps in case u need them :)
Step 1: Simplify both sides of the equation.
−2(x+3)=−2x−6
(−2)(x)+(−2)(3)=−2x+−6(Distribute)
−2x+−6=−2x+−6
−2x−6=−2x−6
Step 2: Add 2x to both sides.
−2x−6+2x=−2x−6+2x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
Answer:
C: All real numbers.
Step-by-step explanation:
-2 ( x + 3 ) = -2x -6
-2 times x, -2 times 3
-2x -6 = -2x -6
Add 6
-2x -6 +6 = -2x -6 +6
-2x = -2x
same as....
0 = 0

A = 200 + 200 + 400 = 800
B = 329.11 + 288.06 + 106.40 rounded to the nearest hundred
B = 300 + 300 + 100 = 700
800 is greater than 700. Thus, A > B.
Answer:
800 is greater than 700. Thus, A > B.

Answer:
Option 4th is correct
Step-by-step explanation:
GCF(Greatest common factor) is the largest number that divide the polynomial.
Given the statement:
the quantity 10 times x to the 6th power times y to the third power plus 20 times x to the third power times y to the 2nd power all over 5 times x to the third power times y
⇒
To simplify this expression:
GCF of and
is,
then;
⇒
Using distributive property:
⇒
Therefore, the simplified expression is,
10x^6y^3 / 5x^3y ⇒ 2x^3y^2
20x^3y^2 / 5x^3y ⇒ 4y
2x³y² + 4y This is the simplified answer. The last option.

while flying (150 - 90) = 60 miles.
If the descent is modeled by a linear function, then the slope
of the function is
(-6000 ft) / (60 miles) = - 100 ft/mile .
Since it still has 19,000 ft left to descend, at the rate of 100 ft/mi,
it still needs to fly
(19,000 ft) / (100 ft/mile) = 190 miles
to reach the ground.
It's located 90 miles west of the runway now. So if it continues
on the same slope, it'll be 100 miles past the runway (east of it)
when it touches down.
I sure hope there's another airport there.
Answer:
airplane will over shoot the runway by 100 miles (for USA Test Prep people)
Step-by-step explanation:
slope =
25,000 - 19,000
150 - 90
= 100
y = mx + b
25,000 = 100(150) + b
25,000 - 15,000 = b
b = 10,000
thus,
y = mx + b
0 = 100x + 10,000
-10,000 = 100x
x = -100
When the plane is at ground level (y = 0), it will be 100 miles past the end of the runway.

2. If the payment is bi-weekly, and there are 4 weeks in a month, you only have to multiply by 2, because "bi-weekly" means every 2 weeks, which means the payment would come twice a month. So, the answer would be A, Multiply by 2 and then round.
3. Round each of the numbers. 978 becomes 980, 54.89 becomes 55, and 93 becomes 90. We'll assume that there are 4 weeks in a month. Add them all up. 980+55+90+90+90+90 = 1395 So, yes, your answer of D, 1,400.00 is a good estimate.
4. Again, round each of the numbers. 455 can stay the same, 34.95 becomes 35, 65.88 can stay at 65 for the sake of easy math, and 87 gets rounded up to 90.
We'll keep assuming that there are 4 weeks in a month. Now, add them all up. Be sure to remember that the rent is bi-weekly, so it has to be added in twice. 455+455+35+65+90+90+90+90 = 1370. This means that of the choices, D, 1,359.00 is a good estimate of the monthly expenses.
