Answer:

C) -7/3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-(-5))/(-2-4)=(9+5)/-6=14/-6

simplify -14/6 to -7/3

Where does the line through (1, 0, 1) and (4, −3, 3) intersect the plane x + y + z = 6?

Irina-Kira [14]

Parametrically for real t the line is

$(x,y,z) = (1-t)(1,0,1) + t(4,-3,3)$

$(x,y,z) = (1,0,1) + t(4-1,-3-0,3-1)$

$(x,y,z) = (1,0,1) + t(3,-3,2)$

That's three equations; we substitute into

$x+y+z=6$

$(1+3t)+(0-3t) + ( 1+2t)=6$

$2t=4$

$t=2$

$(x,y,z) = (1,0,1) + 2(3,-3,2) = (7,-6,5)$

The intersection is a single point (7,-6,5).

4.) solve for f(g(2))

Westkost [7]

Answer:

$f(g(2))=10$

Step-by-step explanation:

We have the two functions: $f(x)=3x-5$ and $g(x)=2+\frac{6}{x}$ .

We want to find $f(g(2))$ .

So, let's use the second function to find $g(2)$ first:

$g(2)=2+\frac{6}{2}$

Divide:

$g(2)=2+3$

Add:

$g(2)=5$

Therefore, our expression is the same to $f(g(2))=f(5)$ .

Now, we can substitute 5 for f(x). This yields:

$f(5)=3(5)-5$

Multiply:

$f(5)=15-5$

Subtract:

$f(5)=10$

So:

$f(g(2))=10$

And we're done!

Can you help me in seeing if its right

Scorpion4ik [409]

Answer: The answer to that would be 4/5= 32/40.

Step-by-step explanation: It is 4/5 =32/40 because if you were to divide the 40 by the 5 you would get 8. Since you got 8 when dividing 40 by 5 you would multiply 8x4. You would do this because whatever you do to the denominator you would do to the numerator. So you would multiply 4/5 x 8/8 and get 32/40. PLEASE MARK BRAINLIEST!!!!
