Answer:

Step-by-step explanation:

$3x+5=x-3\qquad\text{subtract 5 from both sides}\\\\3x+5-5=x-3-5\\\\3x=x-8\qquad\text{subtract}\ x\ \text{from both sides}\\\\3x-x=x-x-8\\\\2x=-8\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{-8}{2}\\\\x=-4$

Hello!

Here are the steps to your problem:

3x + 5 = x - 3

3x -x = -3 -5

2x = -8

x = -4

I hope this helps you! Have a lovely day!

The hover dam contains 3 1/2 millon cubic yards of concrete.The grand coulee dam contains 2 1/2 times as much. How much concrete

Margarita [4]

grand coulee dam (g) contains 2.5 times as much concrete as the hover dam (h)

Therefore,

g = 2.5 * h

h = 3.5 million

g = 2.5 * 3.5

g = 8.75 million yards of concrete

Please help!! will give brainliest and 20points!!! SUPER EASY PROBLEM

Fiesta28 [93]

Answer:

C. 184 ft²

Step-by-Step Explanation:

The formula for the surface area of a triangular prism is

SA = bh + 2ls + lb; where b = base, h = height, l = length, s = side

First, substitute the known value into the equation:

b = 6 ft

h = 4 ft

l = 10 ft

s = 5 ft

SA = (6)(4) + 2(10)(5) + (10)(6)

Then, all we have to do is simplify:

SA = 24 + 2(50) + 60

SA = 24 + 100 + 60

SA = 184 ft²

Hope this helps!

Help please<br> solve for x

Katen [24]

Since A and B are parallel lines, the two marked angles are congruent.
Then, 2x + 12 = x + 25
We can solve for x:
x = 13

Find the slope of the tangent line to the curve f(x)=e^(x) at (0.4,1.49)

almond37 [142]

Answer:

1.49

Step-by-step explanation:

In order to find the slope of the tangent line to a given equation, and in a given point, we need to:

1. Find the first derivative of the given function.

2. Evaluate the first derivative function in the given point.

1. Let's find the first derivative of the given function:

The original function is $f(x)=e^{x}$

But remeber that the derivative of $e^{x}$ is $e^{x}$

so, $f'(x)=e^{x}$

2. Let's evaluate the first derivative function in the given point

The given point is (0.4,1.49) so:

$f'(x)=e^{x}$

$f'(0.4)=e^{0.4}$

$f'(x)=1.49$

Notice that the calculated slope of the tangent line is equal to the y-coordinate of the given point because f'(x)=f(x). In conclusion, the slope of the tangent line is equal to 1.49.
