The car is driving at 70 miles per hour which is above the speed limit on the highway

<h3 /><h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and m is the y intercept.

Let y represent the distance in miles and x represent the time in hours. Hence:

  • Using the points (0, 0) and (3, 200)

Slope = \frac{y_2-y_1}{x_2-x_1} =\frac{200-0}{3-0} =66.7

Bob speed limit is 66.7 miles per hour

Given a car by y = 70x. The car is driving at 70 miles per hour which is above the speed limit on the highway

kogti [31]

Answer:

y-b/m = x

Step-by-step explanation:

y = mx + b

~Subtract b to both sides

y - b = mx

~Divide m to both sides

y-b/m = x

Best of Luck!

Solve 3sinx-4sin^3 x= -1
postnew [5]
Hello,

Since 3sin x-4sin^3x=sin (3x)  (*****)
3sin x-4sin^3x=-1
==>sin (3x)=-1
==>3x=3π/2 +2kπ
==>x=π/2+2kπ/3, k being an integer

(*****)
sin (3x)=sin(x+2x)=sin x cos2x+cos x sin 2x
=sin x(cos²x-sin²x)+2cos²x sin x
=sin x(cos²x+2cos²x-sin²x)
=sinx(3(1-sin²x)-sin²x)
=3sin x-4sin^3x

f(x)=8−4x−x3 g(x)=x2+7x−9 Find f(x)+g(x). Select one: a. x3+x2+3x−1 b. −x3+x+3x−1 c. −x3+x2+11x−9 d. 8x2+3x−9x3
vovangra [49]

Answer:

B

Step-by-step explanation:

We are given the two functions:

f(x) = 8 - 4x - x^3\text{ and } g(x) = x^2 + 7x - 9

And we want to find:

f(x) + g(x)

Substitute:

= (8 - 4x - x^3) + (x^2 + 7x - 9)

Rewrite:

= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)

Combine like terms:

= -x^3 + x^2 +3x -1

In conclusion:

f(x) + g(x) =  -x^3 + x^2 +3x -1

Hence, our answer is B.
