2.3x+4.1(1310-x)=4597
Solve for x
2.3x+5,371-4.1x=4597
2.3x-4.1x=4597-5371
−1.8x=−774
X=-774/-1.8
X=430 standard version

Determine if two triangles are congruent. If they are, state how you know.
nataly862011 [7]

Answer:

B. SSS

Step-by-step explanation:

The two triangles already have 2 congruent sides, and the only missing thing to see is that they both share the same side with one another. This automatically makes them congruent.

Math help pls i don’t understand how to solve this

<h3>Answer:    y = x+1</h3>

===================================================

Explanation:

f(x) = x^3 - 2x + 3

f ' (x) = 3x^2 - 2 ..... apply the power rule

f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point

f ' (1) = 1

If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value.

Now apply point slope form to find the equation of the tangent line

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

y = x - 1 + 2

y = x + 1   is the equation of the tangent line.

The graph is shown below. I used GeoGebra to make the graph.

The equation is 18.1 - x = -0.7

18.1 - -0.7 =
18.1 + 0.7 = 18.8

18.1 - 18.8 = -0.7

Florida’s 3-month temperature is 18.8 degrees C warmer than Montana’s.
