Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. ex = 3 − 2x, (0

, 1) The equation ex = 3 − 2x is equivalent to the equation f(x) = ex − 3 + 2x = 0. f(x) is continuous on the interval [0, 1], f(0) = _____, and f(1) = _____. Since f(0) < 0 < f(1) , there is a number c in (0, 1) such that f(c) = 0 by the Intermediate Value Theorem. Thus, there is a root of the equation ex = 3 − 2x, in the interval (0, 1)

Answer:

f(0)=-2\\f(1)=e-1

Step-by-step explanation:

According to intermediate value theorem, if a function is continuous on an interval [a,b], and if k is any number between f(a) and f(b), then there exists a  value, x=m, where a, such that f(m)=k

In the given question,

Intermediate Value Theorem is used to show that there is a root of the given equation in the specified interval.

Here,

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

Put x=0

f(0)=e^0-3+2(0)=1-3+0=-2

Put x=1

f(1)=e^1-3+2(1)=e-3+2=e-1

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly
frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

y-7 = -\frac{5}{2} (x+6)

y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8<------ Answer

Hope that helps!

You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed? 3x-2y=7 equati
svetlana [45]

Answer:

x = 31/9 and y = 5/3

Step-by-step explanation:

It is given that,

3x - 2y = 7  -----(1)

3x + 4y = 17 ----(2)

<u>To find the solution by elimination method</u>

Step 1: Subtract eq(2) from eq(1)

3x - 2y = 7  -----(1)

<u> 3x + 4y = 17 </u>----(2)

0  - 6y = -10

6y = 10

y = 10/6 = 5/3

Step 2: Substitute the value of y in eq (1)

  3x - 2y = 7  -----(1)

  3x  - 2*(5/3) = 7

  3x = 7 + 10/3

  3x = 31/3

   x = 31/9

Therefore x = 31/9 and y = 5/3

(1+2i) (2+5i)
Lostsunrise [7]

Answer:

Step-by-step explanation:

first multiply 1 with 2+5i then multiply 2i with 2+5i and you will get

2+5i+4i+10i^2

then in the next step add 4i and 5i you will get 9i

in the next step put i^2=-1 and you will get -10

in the last step just substract 2-10 you will get -8 and 9i

and your answer will be -8+9i
