8.5x-6.1=-7.1 round to the nearest tenth

Mathematics

Rainbow [258]4 years ago

Answer & Step-by-step explanation:

8.5x-6.1=-7.1

Add 6.1 to both sides:

8.5x-6.1+6.1=-7.1+6.1\\\\8.5x=-1

Isolate the variable x. Divide both sides by 8.5:

\frac{8.5x}{8.5} =\frac{-1}{8.5}\\\\ x=-\frac{1}{8.5}

Round to the nearest tenth. Simplify division:

-\frac{1}{8.5}=-0.11764705...=-0.1

So, x≈-0.1

:Done

8.5x-6.1=-7.1

40x-6.1=-7.1

40x=-7.1+6.1

40x=-1

solution= x= -0.025

Don’t know how to solve, help ?
yawa3891 [41]
I believe the answer is 88 because the 120 will create a straight angle which is 180. Then you do 180-120=60. This is the measure I the left angle. Now your answer will be 88

Write a definite integral that represents the area of the region. (Do not evaluate the integral.) y1 = x2 + 2x + 3 y2 = 2x + 12F
Svet_ta [14]

Answer:

A = \int\limits^3__-3}{9}-{x^{2}} \, dx = 36

Step-by-step explanation:

The equations are:

y = x^{2} + 2x + 3

y = 2x + 12

The two graphs intersect when:

x^{2} + 2x + 3 = 2x + 12

x^{2} = 0

x_{1}  = 3\\x_{2}  = -3

To find the area under the curve for the first equation:

A_{1} = \int\limits^3__-3}{x^{2} + 2x + 3} \, dx

To find the area under the curve for the second equation:

A_{2} = \int\limits^3__-3}{2x + 12} \, dx

To find the total area:

A = A_{2} -A_{1} = \int\limits^3__-3}{2x + 12} \, dx -\int\limits^3__-3}{x^{2} + 2x + 3} \, dx

Simplifying the equation:

A = \int\limits^3__-3}{2x + 12}-({x^{2} + 2x + 3}) \, dx = \int\limits^3__-3}{9}-{x^{2}} \, dx

Note: The reason the area is equal to the area two minus area one is that the line, area 2, is above the region of interest (see image).
