Answer:

a) b^{3}

b) x^{3}

Step-by-step explanation:

a) Since it is division, you just subtract the powers from each other

b^{7} /b^{4} =b^{7-4} =b^{3}

b) First add the powers on the top, then divide

\frac{x^{1} *x^{5} }{x^{2} *x^{1} } =\frac{x^{1+5} }{x^{2+1} } =\frac{x^{6} }{x^{3} } =x^{6-3} =x^{3}

Find the value of x<br> -3x - 5 = 16
Kazeer [188]

Answer:

x=-7

Step-by-step explanation:

so if you multiply two negative numbers you get a positive and and -7 * -3 is just doing 3*7 which is 21 and that is the answer to -3*-7 and 21 minus 5 is 16 so there´s that and hope this helps

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show your work.
Gemiola [76]
Sum of the angles of any quad =360
then y+(x+2)+(x-2)+(x-10) = y +3x -10 =360 (by adding both sides by 10)
y + 3x =370 ;.... eq 1
the sum of each two opposite sides in a quad inscribed in a circle =180
then (x+2)+(x-2)=180 
therefore 2x =180
therefore x=90  (sub in eq 1)
y+3*90 =y +270 = 370 (subtracting both sides by 270)
therefore y=100
then measure angle B=100 degrees
A=92 degrees
C=88 degrees
D=80 degrees

Complete the table and then graph the function.<br> y = x + 1 look at photo
JulsSmile [24]
Since y=x+1 you get your first x value which is 2 and add one which is 3. Your first coordinate is (2,3) now the second one is 5 so 5+1=6 meaning your coordinate is (5,6) and so on a so forth so technically just add one to the x able and use your x value and the new value you just solved for to create the new coordinate to graph

How do you find the angle for n? If you can, please show work on how to get to the answer. Thank you!
PtichkaEL [24]
A triangle needs to add up to 180 degrees so 44 plus 37 is 81 so that last angle is 99 degrees then you do 180 minus that angle because those 2 angles need to equal up so not equals 81
