x^2=x+2
Please solve by factoring
But I’ll take anything honestly
Answer:
Step-by-step explanation:
[tex]\sf x^2=x+2[/tex]
Subtract x+2 from both sides of the equation:
[tex]\sf x^2-(x+2)=x+2-(x+2)[/tex]
[tex]\sf x2-x-2=0[/tex]
Now, factor left side of equation:
[tex]\sf (x+1)(x-2)=0[/tex]
Set the factors equal to zero:
[tex]\sf x+1=0[/tex] [tex]\sf x-2=0[/tex]

18x-27-6x
12x-27
Answer:
[tex] \sf \: 4x - 11 [/tex]
Step-by-step explanation:
Given expression,
→ 4 + 5(2x - 3) - 6x
Let's simplify the expression,
→ 4 + 5(2x - 3) - 6x
→ 4 + 10x - 15 - 6x
→ (10x - 6x) + (4 - 15)
→ (4x) + (-11)
→ 4x - 11
Hence, the answer is 4x - 11.

Challenge An airplane is preparing to land at an airport. It is 36,000 feet above the ground and is descending at the rate of 3,200 feet per minute. At the same airport, another airplane is taking off and will ascend at the rate of 2,800 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be? Use pencil and paper. Use two other methods to solve the problem. Explain which methods are easier to use and which are more difficult to use for the situation
They will be at the same altitude in _ minutes, when their altitude will be _ feet.
Answer:
6 seconds., 16800 feet
Step-by-step explanation:
The first plane is going y = -3200x + 36000
The second plane is going y = 2800x
Substitute the second equation for y into the first one:
2800x = -3200x + 36000
6000x = 36000 (Add 3200x to both sides)
x = 6 (Divide each side by 6000)
That means they will be the same altitude at 6 minutes.
To find how high, put your answer into one of the equations.
y = 2800 (6)
y = 16,800 feet

Answer:
11) 7 ( Answer A)
12) (-2) ( Answer D)
Step-by-step explanation:
You can use y = m x + c to answer these questions.
In the equation y = m x + c,
m = slope
c = y - intercept
According to the question,
they have given the equation,
y = 7 x - 2
So, you can replace it with y = m x + c like this.
y = 7 x - 2
↑ ↑
m c
There fore,
slope = 7
y - intercept = ( - 2)
And now let's write the answers for the question.
11) 7 ( Answer A)
12) (-2) ( Answer D)
Hope this helps you :-)

hunter has a jar of 368 nickels and dimes. the total value of coins is $28.40. which system of equations below would be the best to use to find the number of nickels and dimes hunter has?
Answer:
We can't see your answer choices, but it would be n + d = 368 and .05n + .10d = 28.40
Step-by-step explanation:
n+d=368 and 0.05n+0.1d=$28.40 is the system of equations below would be the best to use to find the number of nickels and dimes hunter has
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that hunter has a jar of 368 nickels and dimes.
The total value of coins is $28.40.
We need to find the system of equations below would be the best to use to find the number of nickels and dimes hunter has
The total quantity of nickels and dimes is 328
n+d=368
The value of nickel is 0.05 dollars
The value of dime is 0.10 dollars
0.05n+0.1d=$28.40
Hence, n+d=368 and 0.05n+0.1d=$28.40 is the system of equations below would be the best to use to find the number of nickels and dimes hunter has

abebe is 12 years old and his sister aster is 2 years old. In how years abebe be exactly twice as old as aster
Answer:
8 years
Step-by-step explanation:
Currently
Abebe → 12 years old
Aster → 2 years
With every passing year, each of them will be 1 year older hence the difference between their ages will remain constant.
Difference in ages
= 12 -2
= 10
Let the age of Aster be x years old when Abebe is twice her age.
Abebe → 2x years old
Aster → x years old
Difference in age
= 2x -x
= x
x= 10
Aster is 10 years old when Abebe is twice her age.
Number of years passed
= 10 -2
= 8
Thus, Abebe will be twice as old as her sister in 8 years.

suppose y varies directly as x. suppose also that y=34 when x=17. find y when x=56.
Answer:
112
Step-by-step explanation:
We can write the equation for the direct variation:
y = kx
34 = k(17)
34/17 = k = 2
Then for the new x-value:
y = 2(56) = 112
The value of y is 112 when x = 56.
__
Or, we can write the relation as a proportion:
y/56 = 34/17
y = 56(34/17) = 112
