Problems with Equations:

Bas_tet [7]

Answer:

x = 11

The value "11" makes the equation true.

2 ( x - 5 ) = 12

2 ( 11 - 5 ) = 12

2 ( 6 ) = 12

12 = 12

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

Dont forget to make this the brainliest answer to help those in need. also add a 5 star and a heart. thanks for the support hope it helped. have a nice day

Fibd the distance and midpoint between each pair of points. C(-2,2) d(5,-3)

Anika [276]

Answer:

D= $\sqrt{10}$ or about 3.2 M=(1.5,-0.5)

Step-by-step explanation:

D= $\sqrt{(x2+x1)^2 +(y2-y1)^2}$ M= $(\frac{x1+x2}{2} , \frac{y1+y2}{2} )$

Lets find the distance first:

D= $\sqrt{(5+-2)^2 + (-3+2)^2}$

D= $\sqrt{(3)^2+(-1)^2}$

D= $\sqrt{9+1}$

D= $\sqrt{10}$

D is about = 3.2

Lets find the midpoint now:

M= $(\frac{-2+5}{2} , \frac{2+-3}{2} )$

M= $(\frac{3}{2} ,\frac{-1}{2} )$

M= (1.5,-0.5)

The line x+ 2y = 9 intersects the curve xy + 18 = 0 at the points A and B. Find the coordinates of A and B.

victus00 [196]

Subtracting the second equation by 18 on both sides, we have xy=-18. Next, we divide both sides by x to get y=-18/x Plugging that into the first equation, we have x+2(-18/x)=9. Multiplying both sides by x, we get x^2-36=9x. After that, we subtract both sides by 9x to get x^2-9x-36=0. Finding 2 numbers that add up to -9 but multiply to -36, we do a bit of guess and check to find the answers to be -12 and 3. Factoring it, we get
x^2-12x+3x-36=x(x-12)+3(x-12)=(x+3)(x-12). To find the x values, we have to find out when 0=(x+3)(x-12). This is simple as when you multiply 0 with anything, it is 0. Therefore, x=-3 and 12. Plugging those into x=-18/y, we get x=-18/y and by multiplying y to both sides, we get xy=-18 and then we can divide both sides by x to get -18/x=y. Plugging -3 in, we get -18/-3=6 and by plugging 12 in we get -18/12=-1.5. Therefore, our points are (-3,6) and (12, -1.5)
