If f(x) = -2x - 3, find f(0) - 7. <br><br><br>help please!! I will give brainliest!!!!
VikaD [51]

Hi there!

\huge\boxed{-10}

f(x) = -2x - 3

Plug in 0 for "x" to solve for f(0):

f(0) = -2(0) - 3

f(0) = -3

Since the question is asking you to evaluate f(0) - 7, simply subtract:

-3 - 7 = -10.

I just need help set up
Vilka [71]

Answer:

Step-by-step explanation:

<em>Set up equations (L= Lisa; M = Maria; A = April; J = Jim)</em>

L = 12M

A = 2J

<em>Substitute x for Maria and 6x for Jim</em>

L = 12x

A = 2(6x) = 12x

<em>So, you get:</em>

Maria = x

Jim = 6x

Lisa = 12x

April = 12x

Find the equation of the line through (8,−6) which is perpendicular to the line y=x3−7.
ycow [4]

Answer:

y = (-1/3)(x + 10)

Step-by-step explanation:

The slope of the new (perpendicular) line is the negative reciprocal of the slope of the given line, which appears to be 3.  Thus, the perpendicular line has the slope -1/3.

Using the slope-intercept form y = mx + b, and substituting the givens, we obtain:

y = mx + b    =>    -6 = (-1/3)(8) + b, or

-6 = -8/3 + b.  We must solve for the y-intercept, b:

Multiplying all three terms by 3 removes the fraction:

-18 = -8 + 3b.  Thus, -10 = 3b, and so b must be -10/3.

The desired equation is    

y = (-1/3)x - 10/3, or

y = (-1/3)(x + 10)

Speed, Time, and Dis
serious [3.7K]

Answer:

3 hours

Step-by-step explanation:

Recall:

Distance = speed x time

we are given that speed = 18 km/h and distance = 54 km.

hence,

54 = 18 x time   (divide both sides by 18 and rearrange)

time = 54/18 = 3 hours
