-6x + 6y= 6 -6x + 3y=-12

Mathematics
2 answers:
abruzzese [7]3 years ago

Answer:

(5,6)

Step-by-step explanation:

-6x+6y=6

-6x+3y=-12

solve the equation

-6x+6y=6

-6x=-12-3y

substitute the value of -6x into an equation

-12-3y+6y=6

minus -3y to 6y. and. add -12 to 6

-3y=-18

divide both sides by -3

y=6

substitute the value of 6 into an equation

-6x=-12-3•6

multiply -3 to 6

-6x=-12-18

minus -12 to -18 but since both are negative it's addition

-6x=-30

divide both sides by -6

x=5

the answer is (5,6)

3x+y=4 write the equation in slope intercept form​
LekaFEV [45]

Answer:

y = -3x + 4

Step-by-step explanation:

sorry im late

but all you have to do is isolate the y

so to do that we have to get rid of the 3x

3x + y = 4

in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y

3x + y = 4

-3x          -3x

y = -3x + 4

and now y is isolated

What is the quadratic equation of the curve of best fit shown below
Kisachek [45]
First off, we know that the y-interecept is 2, so there is going to be a plus two in the final equation. Now with the two answers input the number 8 to see which will output 6.

6 = 1/12(8)^(2) + 2
6 = 1/12(64) + 2
6 = 64/12 + 2
6 = 16/3 + 6/3
6 does not equal 22/3

6 = 1/16(8)^(2) + 2
6 = 1/12(64) + 2
6 = 64/16 + 2
6 = 4 + 2
6 = 6
This means that y = 1/16 x^2 + 2 is the correct answer. I hope that helps!

Find cosØ if sinØ=-12/13 and tanØ&gt;0.<br><br> A) -5/12<br> B) -5/13<br> C) 12/5<br> D) -13/12
mestny [16]

Answer:

-5/13

Step-by-step explanation:

sin theta = opp / hyp

sin theta = -12 /13

we can find the adj side by using the pythagorean theorem

adj^2 + opp ^2 = hyp^2

adj^2 +(-12)^2 = 13^2

adj^2 +144 =169

adj^2 = 169-144

adj^2 = 25

Taking the square root of each side

adj = ±5

We know that it has to be negative since it is in the third quad

adj = -5

cos theta = adj / hyp

cos theta = -5/13
