9x - 6y = -21 and 6x - 12y = -6 How would I solve by substitution?
Answer:
(-3,-1)
Step-by-step explanation:
6x-12y=-6
6x=12y-6
x=2y-1
9(2y-1)-6y= -21
18y-9-6y=-21
12y= -12
y=-1
6x-12(-1)=-6
6x+12= -6
6x=-18
x=-3
Answer:
x = -3 ; y = -1
Step-by-step explanation:
Let 9x - 6y = -21 be eqn.1 & let 6x - 12y = -6 be eqn.2 .
Lets find the value of x from eqn.1
[tex]9x - 6y= -21[/tex]
[tex]=> 3(3x - 2y) = -21[/tex]
[tex]=> 3x - 2y = \frac{-21}{3} = -7[/tex]
[tex]=> x = \frac{2y - 7}{3}[/tex]
Now , lets put the value of x (which we got from eqn.1) in eqn.2 :-
[tex]6x - 12y = -6[/tex]
[tex]=> 6(x - 2y) = -6[/tex]
[tex]=> x - 2y = \frac{-6}{6} = -1[/tex]
(Putting x here)
[tex]=> \frac{2y - 7}{3} - 2y = -1[/tex]
[tex]=> \frac{2y - 7 - 6x}{3} = - 1[/tex]
[tex]=> -4 y - 7 = -1 \times 3 = -3[/tex]
[tex]=> -4y = 7 - 3 = 4[/tex]
[tex]=> y = \frac{-4}{4} = -1[/tex]
Now , lets find the value of x.
[tex]x = \frac{2y - 7}{3}[/tex]
Putting y = -0.5 gives ,
[tex]x = \frac{[2 \times (-1)] - 7}{3}[/tex]
[tex]=> x = \frac{-2 - 7}{3} = \frac{-9}{3} = -3[/tex]

please help i'm so confused and its due todayyy :(
will mark brainliest!!
Answer:
C
Step-by-step explanation:
Because lets say we have a point (1,2)
when reflecting this point over the y-axis it becomes (-1,2) so only the sign of the X value changes. Therefore by writing the system f(x)=g(-x) it changes the X value.
Graph a line with a slope of -3 that contains the point (4, -2).

Answer:
y*y*y*y*y
y^5
Step-by-step explanation:
When you multiply exponents with the same base you're supposed to add them so your answer to the first is y^5 but your teacher is being weird and wants you to write it with no exponents so you can just write it 5 times
so number one is y*y*y*y*y
I answered number two in my explanation above
you add the exponents
y^2+y^3=y^5
if you have any questions let me know

IF THE VOLUME OF THE BOX BELOW IS
x3 + 6x2 + 9x + 4
AND THE WIDTH OF THE BOX IS x + 4,
THEN FIND THE LENGTH AND HEIGHT OF
THE BOX
Answer:
The length of the box is (x + 1)
The height of the box is (x + 1)
Step-by-step explanation:
The given function representing the volume of the box is presented as follows;
V = x³ + 6·x² + 9·x + 4
The function representing the width of the box, W = x + 4
Therefore, we have;
(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1
x³ + 4·x²
[tex]{}[/tex] 2·x² + 9·x + 4
[tex]{}[/tex] 2·x² + 8·x
[tex]{}[/tex] x + 4
Therefore, we have;
(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)
(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)
The width of the box = (x + 4)
The length of the box = (x + 1)
The height of the box = (x + 1).
