Y decreased by 23 is 52.9....
y - 23 = 52.9 <== ur equation
y = 52.9 + 23
y = 75.9
================
c - 12 = 6 <== ur equation
c = 6 + 12
c = 18
================
h - 234 = 1192
h = 1192 + 234
h = 1426
no, he is not correct because he did not add 234 and 1192 to find the value of h, which is 1426

Can someone please help me answer my question
algol [13]
The surface area would be 150cm and the volume would be 125cm. To get volume you do 5 cubed to get the answer 125. To get surface area you would do 5 multiplied by 5 multiplied by the cubes 6 sides to get 150.

Hey there! I'm happy to help!

Let's think of this as the equation y=mx+b, where m represents the slope and b equals the y-intercept.

The y-intercept is where the line hits the y-axis. As we can see, it hits it at the y-value of zero. Therefore, our equation is just left as y=mx now because b is 0.

We want to find the slope now. This is known as the rise/run, or the y/x. This is basically saying how far up it goes for every one step to the right. If we go to the x-value of one, we see that the y-value is at a little bit less than one. We want to keep on moving to the right until the y-value is at a nice integer value (number without fractions).

If we keep on moving to the right, we see that at the x-value of 3, the y is at 2. This means that the slope is 2/3. And it makes sense! When we were looking at that value of 1, the y-value was less than one and looked like it was at about 2/3, or 0.666....

This will apply to all points on the line. Our y will always be 2/3 of what x is.

Therefore, the equation is y=2/3x

I hope that this helps! Have a wonderful day!

Solve: e^2x + 5 = 4<br> help pls
kaheart [24]

Answer:

The solution of the equation is x=\frac{(ln4)-5}{2} ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve this problem

- The function f(x) = e^x is called the (natural) exponential function

- The natural logarithm (㏑), or logarithm to base e, is the inverse

 function to the natural exponential function

∵ e^{2x+5}=4 is an exponential function

∴ We can solve it by using the inverse of e (㏑)

- Remember:

# ln(e)=1

# ln(e^{m})=m(ln(e))=m

- Insert ln in both sides

∴ ln(e^{2x+5})=ln(4)

∵ ln(e^{2x+5})=(2x+5)ln(e)=2x+5

∴ 2x + 5 = ㏑(4)

- Subtract 5 from both sides

∴ 2x = ㏑(4) - 5

- Divide both sides by 2 to find x

∴ x=\frac{ln(4)-5}{2}

* The solution of the equation is x=\frac{(ln4)-5}{2}
