Answer:

-9 =x

Step-by-step explanation:

We know these are similar triangles

We can use ratio's to solve

Let CS = y  and XR = y+y or 2y

y           x+19

------ = ------------

2y         x+29

We can simplify the ratio on the left by dividing by y

1           x+19

------ = ------------

2         x+29

Using cross products

1(x+29) = 2(x+19)

Distribute

x+29 = 2x+38

Subtract x from each side

x-x+29 = 2x-x+38

29 = x+38

Subtract 38 from each side

29-38= x+38-38

-9 =x

Suppose A and B represent two different school populations where A > B and A and B must be greater than 0. Which of the follo
Ulleksa [173]
We can reject the last one: subtracting a non-zero value will result in a smaller value.

So now we have:

<span>2(A + B)
(A + B)2
A2 + B2

If all of them are mulptiplications, then they are all equivalent!

I mean by this, if what you meant is this:

</span>
<span>2*(A + B)
(A + B)*2
A*2 + B*2

If there is no sign, then the multiplication sign is implicit,


and all of these expressions say exactly the same: two of A and two of B.

1<br> Determine the number of solutions for the equation.<br> - 3(42x +46) = -15(-22-9x)
kkurt [141]

Answer:

x=-52/29

Step-by-step explanation:

-3(42x+46)=-15(-22-9x)

-126x-138=330+135x

-126x-135x-138=330

-261x-138=330

-261x=330+138

-261x=468

x=468/-261

x=-52/29

Given that x &lt; 5, rewrite 5x - |x - 5| without using absolute value signs.
arsen [322]

For x, x-5, therefore |x-5|=-(x-5)=-x+5

So, for x, 5x-|x-5|=5x-(-x+5)=5x+x-5=6x-5

Left and Right end behavior of f(x)=2e^x+3 written in infinity notation.
Verizon [17]

Answer:

I think you wanna know exactly it's graph

See f(x)= 2 e^x +3

e^x is exponential function which is always positive and so lies above x axis

Multiply by 2 make it's incrementation in slope and now it will pass through (0,2)

Also adding 3 shifts graph 3 unit above y axis

So Now it will pass through (0, 2+3) that is B) (0,5)

Now At x approaches to minus infinity it will shift 3 unit up from 0 to 3 So it will pass through (-infinity,3)

Now see the pic
