3x + 2y = -10
5x + y = 9
Answer:
x=4, y=-11. (4, -11).
Step-by-step explanation:
3x+2y=-10
5x+y=9
--------------
3x+2y=-10
-2(5x+y)=-2(9)
--------------------
3x+2y=-10
-10x-2y=-18
-----------------
-7x=-28
7x=28
x=28/7=4
5(4)+y=9
20+y=9
y=9-20=-11
a circular garden has a diameter of 12 feet. what is the best approximation for the circumference of the garden? use 3.14 to approximation pi
Answer:
37.68
Step-by-step explanation:
C(circumference)= 2pi r
If the diameter is 12, the r adius is 6
plug into equation
2(pi)(6)
=12pi
=37.68
Answer:
37.68 for K12
what would 4xy + 6y be? factoring and its not what i thought the answer was fdkjdfnds
Answer:

Step-by-step explanation:
Collecting like terms, 6+4=10 and the two y's will make y^2
Find the x- and y-intercepts of the graph of the linear equation 3x+6y=2
Answer:
x-intercept: 2/3
y-intervept: 1/3
Step-by-step explanation:
3x + 6y = 2
You're supposed to 'cover them'.
If you want to find the x-intercept, you will cover 6y like it doesn't exist. So now, it's going to be:
3x = 2
You'll then solve for x, which will be the x-intercept
3x/3 = 2/3 (Divide both sides by 3)
x = 2/3 or 0.66... (the 6 goes on forever)
Now, to find y, you'll act like x doesn't exist. It's going to be:
6y = 2
Solve for y, which will be the y-intercept
6y/6 = 2/6 (Divide both sides by 6)
y = 1/3 or 0.33... (the 3 goes on forever)
If you put them as coordinates:
x-intercept: (2/3, 0)
y-intercept: (0, 1/3)

-4x+5 + -13x+39=180 angle measure
Step-by-step explanation:
−4x+5−13x+39=180
Step 1: Simplify both sides of the equation.
−4x+5−13x+39=180
−4x+5+−13x+39=180
(−4x+−13x)+(5+39)=180(Combine Like Terms)
−17x+44=180
−17x+44=180
Step 2: Subtract 44 from both sides.
−17x+44−44=180−44
−17x=136
Step 3: Divide both sides by -17.−17x
−17
=

if dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3
Answer:
The equation of the tangent line passing through the point (-2,3) is
4 x + y +5 =0
Step-by-step explanation:
Step(i):-
Given that the slope of the tangent
[tex]m = \frac{dy}{dx} = x(y-1)[/tex]
m = -2( 3-1) = -4
Given point x = -2
y = f(-2) =3
∴The given point ( x₁ , y₁) = ( -2 ,3)
Step(ii):-
The equation of the tangent line passing through the point (-2,3)
[tex]y - y_{1} = m(x-x_{1} )[/tex]
[tex]y -3 = -4(x-(-2))[/tex]
y -3 = -4( x+2)
y-3 = -4x -8
4x + y -3+8=0
4x +y +5=0
Step(iii):-
The equation of the tangent line passing through the point (-2,3) is
4 x + y +5 =0

Jonah had 3/4 cup of water in his cup. He drank 1/2 cup of water. How
much water did he have left?
Answer:
1/4th Cup left
Step-by-step explanation:
1/2 cup is equal to 2/4 cup, so subtract that from 3/4th and you end with 1/4th

Which of the following inequalities is the solution to the number line?
Answer:
A
Step-by-step explanation:
- 5x + 4 > 9 ( subtract 4 from both sides )
- 5x > 5
Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity.
x < - 1

Find the slope and the y-intercept of the graph of y+1=4/3x.
What is the slope and the y-intercept?
Answer:
Slope = 4/3x; y-intercept = -1
Step-by-step explanation:
y + 1 = 4/3x
You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept
y + 1 = 4/3x
Subtract one from both sides
y + 1 - 1 = 4/3x - 1
y = 4/3x - 1
Now that we have the equation, you can now find the slope and y-intercept
y = mx + b; m is the slope and b is the y-intercept
So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
