Answer:

31. (98,765 x 9) + 3 = 888,888

32. (12,345 x 9) + 6 + 111,111

33. 3367 x 15 + 50,505

34. 15,873 x 28 = 555,555

35. 33,334 x 33,334 = 1,111,155,556

36. 11,111 x 11,111 = 123,454,321

41. 3 + 9 + 27 + 81 + 243 = 3(243 -1) / 2

42.  1/1x2 + 1/2x3 + 1/3x4 + 1/4x5 + 1/5x6 = 5/6

<em>hope this helps</em>

4y+8=2\qquad|\text{subtract 8 from both sides}\\\\4y=-6\qquad|\text{divide both sides by 4}\\\\y=-\dfrac{6}{4}\\\\\boxed{y=-\dfrac{3}{2}\to y=-1.5}

Need help plz thanks I need help with the other probs I posted under the name YasElm

Since they are alternate interior angles, they will be congruent with each other.

4x= 5x-30

Subtract 5x on each side.

-1x= -30

Divide -1 into both sides.

x= 30

Now just plug in 30 too (4x) for the angle measure of both sides.

4*30 = 120

Each angle is equal to 120.

Hope this helps!

(c) For what value of the domain(-3,-1,0,2,5) does f(x)= g(x) (-3,-1,0,2,5) ?
fiasKO [112]
Info from question brainly.com/question/1025208


so we have
f(x)=3x-4 and
g(x)=x(2)-2
the x(2) should mean 2 times x or 2x, but if it means x^2 then
g(x)=x^2-2
solution set is represented by S={solutions}
so to see what values make them equal, we set them equal to each other

if x(2)=2x then go to AAAAAAAAAA
if x(2)=x^2 then go to BBBBBBBBBBBBB



AAAAAAAAAAAA
3x-4=2x-2
subtract 2x from boths ides
x-4=-2
add 4 to both sides
x=2
therefor the number that would satisfy the thingumy is the value of  2 so
S={2}



BBBBBBBBBB
3x-4=x^2-2
subtract (3x-4) from both sides
0=x^2-3x+2
factor
(x-2)(x-1)=0
set each to zero
x-2=0
x=2

x-1=0
x=1

so the answer is x=1 or 2 so
S={1,2}



so the answer is
if x(2)=2x then S={2}
if x(2)=x^2 then S={1,2}

Is the point (4,11) a solution to the following system of equations? How do you know?
rjkz [21]
No because when you plug in the ordered pair to either equation it doesn’t work. Y=2x+14 would go to 11=2(4)+14 and you would get 11=22 which is wrong. Again with y=3x-5 would be 11=3(4)-5; 11=7 which is wrong again.

Which graph shows f(c)=0.5|x+3|-2
iVinArrow [24]

The graph that shows f(c)=0.5|x+3|-2 has been added in the attachment.

<h3>How to solve for the graph</h3>

We are given the equation to be f(x) = 0.5|x + 3| – 2

This equation above is an absolute value equation that was entered into a graphing calculator

The absolute value equation is represented by the values

f(x) = a|x - h| + k

in the equation above, h and k are the vertex of the graph

when we compare the absolute value equation with the equation we have in the question, we would have h = +3 and k = -2

Hence we would say that the vertex is 3 , -2.

When the graph was plotted, the vertex is the point that shows that meeting at a point in the point 3, - 2 are shown as the vertex also
