Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!

Which letter is in the solution set for graph #2
Answer:
AStep-by-step explanation:
y > 0 - the region above the line together with that line
y ≥ 0 - the region above the line together with that line
y < 0 - the region below the line without that line
y ≤ 0 - the region below the line together with that line
We have:
y > 2 - the region above the line together with that line
y ≥ 2x - 3 - the region above the line together with that line

I'm pretty sure its 70 because write it as a fraction 28/40 when divide them both and you get 0.7 which is 70. I hope that works
Identify the slope and y-intercept. If the equation is in standard form, you may need to switch it to slope-intercept form. Sketch the graph of each line.
5x + 4y = 4
Answer:
Slope= -5/4
Y-intercept= 1
Step-by-step explanation:
First put into slope-intercept form, which would get y= -5/4x+1.
Then identify what's what, with the formula y=mx+b, where m is the slope and b is the y intercept. Using that you can see that -5/4 is the slope and 1 is the y.
Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. For how many years did he save this money?
Answer:
7 years.
Step-by-step explanation:
To find this, we need to find 2% of 2,000. To do this, we mulitply 2,000 by .02. This gets us 40. Now, we need to divide 280 by 40 to find the amount of years it took for Mike to get this money. When we do that, it gets us 7. That means Mike saved that money for 7 years.
The number of years that he saves this money will be 7 years.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The formula for interest is written as,
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. Then the number of years is calculated as,
$280 = ($2,000 x 2 x T) / 100
$28,000 = $4,000 x T
T = $28,000 / $4,000
T = 7 years
The number of years that he saves this money will be 7 years.

Y: 0 3 6 9
helpppppppppppppppppppppppppppppppppppppppppppp PLEASE
Answer:
x = 7/12
Step-by-step explanation:
20 = 15(x + 3/4) (Given)
20 = 15x + 45/4 (Distribute)
35/4 = 15x (Subtract 45/4 on both sides)
7/12 = x (Divide 15 on both sides)
You can substitute the solution for x to check.
20 = 15(7/12 + 3/4)
20 = 15(4/3)
20 = 20

Answer:
x = 23
Step-by-step explanation:
the angles in a triangle add up to 180
the square means 90
90 + 67 + x = 180
157 + x = 180
157 - 157 + x = 180 - 157
x = 180 - 157
x = 23
Write an equation of the line that passes through (0,-5) and is perpendicular to the line y=4/5x.

Step-by-step explanation:
Find the length and width of a rectangle.
Perimeter = 50
Side A = 3x + 2
Side B = x - 5
Step-by-step explanation:
Perimeter = 2 * (Side A + Side B)
= 2 * (3x + 2 + x - 5)
= 2 * (4x - 3)
= 8x - 6.
We have 8x - 6 = 50, so 8x = 56 and x = 7.

The sum of the digits of a two-digit number is 11. When the digits are reversed, the new number is 27 more than the original number. Find the original number. Check your answer.
The original number is 38.
The original number is 47.
The original number is 74.
The original number is 83.
Answer:
-44+-11=11
Step-by-step explanation:
la respuesta es 54 y sí está bien gracias ahora adiós que tengas un buen día 33. Entonces -44 + -11 = 11 pero esa es la billetera que tengo.
Answer:
47
Step-by-step explanation
83 - 38 doesn't equal 27 and it said 27 more so it couldn't be 74 because if it was, it would be 27 less. So the only number left is 47!
M is the midpoint if AB . If coordinates of A are (-1,5) and the coordinates of M are (3,3) , what are the coordinates of B?
Answer:
The co-ordinates of B are ( 7,1)
Step-by-step explanation:
Step(i):-
Given that 'M' is the midpoint of AB
Given co-ordinate points are A(-1,5) and midpoint M(3,3)
we know that the midpoint formula
[tex]midpoint = (\frac{x_{1} +x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]
[tex](3,3) = (\frac{-1+x_{2} }{2} ,\frac{5+y_{2} }{2} )[/tex]
Step(ii):-
Equating
[tex]3 = \frac{-1+x_{2} }{2}[/tex] and [tex]\frac{5+y_{2} }{2} = 3[/tex]
cross multiplication, we get
6 = -1 + x₂ and 6 = 5 +y₂
x₂ = 6+1 and y₂ = 6-5
x₂ = 7 and y₂ = 1
Final answer:-
The co-ordinates of B are ( 7,1)
