Answer:

Infinite amount of solutions

Step-by-step explanation:

Step 1: Write equation

5(x + 2) = 5x + 10

Step 2: Solve for <em>x</em>

  1. Distribute 5x + 10 = 5x + 10
  2. Subtract 10 on both sides: 5x = 5x
  3. Divide both sides by 5: x = x

We see here that <em>x</em> is infinite amount of solutions. We can plug in any value <em>x</em> and it would render the equation true.

o-na [289]
Z=5.714285714285714 because you subtract 0.3z from 0.02z which = 0.28z and then subtract.2 from 1.8 which is 1.6. So then divide 1.6 by 0.28 to find z.

Nastasia [14]

Answer:

v = 25

Step-by-step explanation:

The crucial information you need to know to solve this is to realize that HI and GH are the same length. However, why they are equal is not immediately obvious.

Both sides of the middle line (HF) are symmetrical, since G and I are the same distance away from the line, and they both lie on a line perpendicular to the middle line.

Note: we know they're the same distance away due to the small red marks in the lines, indicating that they're the same length.

The angles at G and I in the triangles are also the same, as the lines from G and I both meet at H. If they were different angles, they would each hit a different point on the middle line.

Thus, we can conclude that GH and HI are the same length.

Since we know the following:

GH = 4v - 75

HI = v

We can set GH and HI equal to each other and solve the equation.

4v - 75 = v

Subtract v from both sides:

3v - 75 = 0

Add 75 to both sides:

3v = 75

Divide both sides by 3:

v = 25

Answer: v = 25

One A
y = e^x
dy/dx = e^x The f(x) = the differentiated function. Any value that e^x can have, the derivative has the same value. x is contained in all the reals.
One B
y = x*e^x
y' = e^x + xe^x Using the multiplication rule.
You want the slope and the value of the of y to be the same. The slope is y' of the tangent line
xe^x = e^x + xe^x
e^x = 0
This happens only when x is very "small" like x = - 4444444

y = e^x * ln(x) Using the multiplication rule again, we need the slope of the line with is y'
y1 = e^x
y1' = e^x
y2 = ln(x)
y2' = 1/x
y' = e^x*ln(x) + e^x/x So at x = 1 the slope of the line = 
y' = e^1*ln(1) + e^1/1
y' = e*0+e  = e
y = mx + b
y = ex + b
to find b we use y= e^x ln(x)

e^x ln(x) = e*x + b
e^1 ln(1) = e*1 + b
ln(1) = 0
0 = e + b
b = - e

line equation and answer.
y = e*x - e

Wanda has $640 in her checking account. She pays her landlord $75 per week for rent.Which function best models the linear relati
umka21 [38]

Answer:

The function best describe the  linear relationship be y = 640 - 75x.

Step-by-step explanation:

As given

Wanda has $640 in her checking account.

She pays her landlord $75 per week for rent.

Let us assume that the number of weeks be x.

Let us assume that the y reresented the money in the account after x weeks.

Than the function becomes

y = 640 - 75x

Therefore the function best describe the  linear relationship be y = 640 - 75x.

Reptile [31]

Answer:

H = 12

Step-by-step explanation:

Add the angles, 54 + 63 + 5h + 3 = 180

simplify into 120 + 5h = 180

5h = 60

h = 12
