Answer: 28 degrees

Step-by-step explanation: Since degree x as well as the 10 ° angle seem to be aligned to a 38 45 ° angle, this would be 38-10=28 degrees.

Answer:

28 degrees

Step-by-step explanation:

because it looks like angle x and the 10 degree angle are vertical to the 38 degree angle so it would be 38-10=28 degrees.

So i have an assignment that needs to be answered quickly please! :) So i need to know how to turn an improper fraction into a m

dezoksy [38]

Say if you have 55/10 thats an improper fraction so in order to turn that into a mixed number divide 55 by 10 which you will get 5. Something right so the 5 will be your whole number 5 then your leftover is 5 so you will put that 5 over 10 so the mixed number will be 5 5/10 but you can simplify that to 5 1/2

50 POINTS!!!

Answer:

f(x) = x
g(x) = -2x+1
f(x) -(-g(x)) = -x+1
f(x) +g(x) = -x+1
f(x)-(-g(x)) = (f+g)(x) is true for all functions f and g, linear or not

Step-by-step explanation:

We can define a couple of linear functions as ...

f(x) = x

g(x) = -2x+1

Then the reflected function -g(x) is ...

-g(x) = -(-2x +1) = 2x -1

And the difference from f(x) is ...

f(x) -(-g(x)) = x -(2x -1) = -x +1 . . . . f(x) -(-g(x))

We want to compare that to the sum of the functions:

f(x) +g(x) = x +(-2x +1) = -x +1 . . . . f(x) +g(x)

The two versions of the function expression have the same value.

These results are <em>a property of addition</em>, so do not depend on the nature of f(x) or g(x). They will hold for every function.

Which expression represents the sixth term in binomial expansion (2a-3b)^10

AysviL [449]

Therefore the sixth term in the binomial expansion is $=-{10}C_5(2a)^{5} (3b)^5$

Step-by-step explanation:

Given

$(2a -3b)^{10}$

$=^{10}C_0 (2a)^{10} + ^{10}C_1(2a)^9(-3b)+^{10}C_2(2a)^8(-3b)^2+...............+^{10}C_10(-3b)^{10}$

So,

$T_{n+1}= ^{10}C_n(2a)^{(10-n)} (-3b)^n$

$T_6=T_{(5+1)} =^{10}C_5(2a)^{10-5} (-3b)^5$

Therefore the sixth term in the binomial expansion is= ${10}C_5(2a)^{10-5} (-3b)^5$

$=-{10}C_5(2a)^{5} (3b)^5$

Solving systems of linear equations by graphing 2x+3y=-12 and 10x+3y=12

Artyom0805 [142]

Answer:

(x, y) = (3, -6)

Step-by-step explanation:

I like a good graphing calculator for solving systems of equations by graphing.

If you're solving these by hand, you need to graph the equations. It can be convenient to put the equations into "intercept form" so you can use the x- and y-intercepts to draw your graph.

That form is ...

x/(x-intercept) +y/(y-intercept) = 1

Dividing a standard-form equation by the constant on the right will put it in this form.

x/(-12/2) +y/(-12/3) = 1 . . . . . . divide the first equation by -12

x/(-6) +y/(-4) = 1 . . . . . . . . . . . the x-intercept is -6; the y-intercept is -4

x/(12/10) +y/(12/3) = 1 . . . . . . divide the second equation by 12

x/1.2 +y/4 = 1 . . . . . . . . . . . . . the x-intercept is 1.2*; the y-intercept is 4

The locations of these intercepts and the slopes of the lines tell you that the solution will be in the fourth quadrant. The lines intersect at (x, y) = (3, -6).

_____

* It can be difficult to draw an accurate graph using an intercept point that is not on a grid line. It may be desirable to put the second equation into slope-intercept form, so you can see the rise/run values that let you choose grid points on the line. That equation is y =-10/3x +4. A "rise" of -10 for a "run" of +3 will get you to (3, -6) starting from the y-intercept of (0, 4).
